[Free Distribution] I made a Windows app that turns 15 minutes of work in Canva into a few seconds | Try it for free 3 times
🎁 First, you can try it completely free for 3 times
Starts immediately upon download, no installation required, and you can use it permanently for ¥1,480 if you like it
Hello, I am Hide.
This might be sudden, but if you
want to show your track record on Coconala or CrowdWorks
want to post a "summary of what I made this month" on Instagram or X
want to display a list of handmade items or AI images all at once on a single sheet
want to make your blog eye-catching images with impact
If any of these apply to you, download the tool from the end of this article and try it for free up to 3 times. If you don't like it, just discard it. I won't push you to buy it any further.
Actually, you are unconsciously paying a "15-minute hell" every month
Achievement images, portfolios, work lists, end-of-month summaries. Just making "one sheet with images packed together" wastes 15 minutes to an hour—have you noticed this?
Dragging in Canva, adjusting sizes, aligning spacing, "Oh, one is misaligned," fixing, previewing, "I want to add one more," layout breaks, starting over from the beginning.
The other day, on a Sunday night when I was updating my Coconala sales page, 15 minutes melted away just to combine 20 achievement images into one tile.
Even with monthly updates, that's 3 hours a year.
If it's weekly, that's 26 hours a year—that's a calculation of spending a full day of your life just "lining up images."
Isn't there work that you don't realize is stealing a massive amount of your time? This is exactly that.
Try calculating it for yourself. How many times have you made "a single sheet with images neatly arranged" in the past year? Coconala achievement images, Instagram end-of-month summaries, presentation materials, blog eye-catchers, year-end reviews... You probably haven't noticed, but 15 to 30 hours of your life have been spent just "lining up images".
At an hourly rate of 2,000 yen, that's 30,000 to 60,000 yen worth. This time will continue to disappear next year, and the year after that. This is the terror of "chronic time leakage." It costs many times more than a monthly Canva Pro subscription, yet no one notices.
I made a tool that finishes that in "a few seconds"
I searched everywhere for existing tools, but there was no tool specialized for "just neatly arranging 20-50 images". Canva is too versatile and slow, Photoshop costs 2,728 yen per month and is heavy to operate, and online services require uploading and have no privacy.
If so, I have no choice but to make it. After finishing it in two weekends, an image grid viewer that completes in a few seconds just by selecting a folder was born.
Time-saving comparison with Canva
It's faster to look at the numbers than to explain in words, so I'll lay them out.
The point is that the gap explodes as the number of images increases.
Actual usage results
Used in situations like these
1. Listing pages on Coconala/CrowdWorks
There is a clear difference in order conversion rates between those who write 'I have 20-50 completed projects' in text and those who post a single tile image with the actual images lined up, which clearly changes the order rate.
The client's psychology is simple. They want to judge in an instant, 'Is it okay to hire this person?' Looking at images is overwhelmingly faster than reading text. A densely packed image of past work is more eloquent than 100 lines of text.
2. 'Monthly Summary' posts on Instagram/X
Have you ever seen the style of posting 'Everything I made this month' in a single image at the end of the month?
This is a classic type of content with exceptionally high repost and like rates. The reason is simple: viewers intuitively react with 'That's an amazing amount!'
3. Product lists for handmade creators
For handmade artists selling works on minne, Creema, BASE, etc. Whether or not you have a single image displaying all your works in a list on your pinned profile post or self-introduction page makes a world of difference in your first impression.
④ Summary images for bloggers and note users
When writing articles like "100 Free Resources," "I tried AI image generation," or "All the eye-catching images from articles I wrote in a year," it is much more impactful to use a tiled image summarizing them into one rather than pasting images one by one in the body of the text.
⑤ Year-end review posts
Posts like "I lined up everything I made in 2026" are classic content that goes viral on social media every December.
⑥ Summary of AI image generation results
If you are generating a large number of images with Midjourney, Stable Diffusion, DALL-E, etc., you can use this to summarize 100 to 500 results. The more you mass-produce images with generative AI, the more you run into the "I made them, but I have no way to show them" problem. With this tool, you can combine 500 generated items into a single mosaic-style image.
⑦ Product catalogs for restaurants and online shops
When sending messages via LINE or DM saying "Check out our menu!" or "Here is our product list," a single image packed with product photos is far more effective than an Excel table. Restaurant menu photos, real estate property photos, apparel seasonal collections—list images as business tools directly lead to conversions.
⑧ Memories of weddings and events
When you want to combine 200 wedding photos, graduation photos, travel photos, or records of your child's growth into a single memorial image. It takes less effort than a photo book, but looks better than an album. Hundreds of photos are combined into a single mosaic.
⑨ Proposal materials for clients
When you want to show "I have created designs with this taste in the past," collect only the relevant works in a folder and list them. If you paste them onto a PowerPoint slide, it becomes a more persuasive presentation than 100 lines of text.
Actual usage stories
Case 1: Illustrator Y on Coconala
Having just started listing, they had 20 achievements, but only wrote "Production achievements: 20" in text on the listing page. When they used this tool to combine the achievement images into a single tile and made it the main image of the listing page, inquiries for that week jumped from 3 to 12.
Y was surprised, saying, "I didn't realize it would make such a difference just by changing how I show them."
Case 2: Handmade artist M
When they posted "I lined up all the accessories I made this year" on X at the end of the year, the tile image of about 80 works received over 120 reposts and 800 likes. With more than 10 times the reaction of their usual posts, traffic to minne also tripled.
Case 3: Thumbnail creator YouTuber K
Although I had a track record of over 200 thumbnails in the past, I had no way to showcase them other than writing numbers in the description box. As a result of using this tool to consolidate 200 thumbnails into a single tile image and repurposing it for description boxes, pinned posts, and PDFs for collaboration requests, new inquiries increased from 5 per month to 20 per month.
Why "densely packed images" are powerful
Reason 1: Quantity is conveyed in 1 second
The human brain recognizes images before text. While it takes several seconds to read text, the overall image is understood in 0.1 seconds. SNS timelines move at high speed, but a single image packed with content will always stop the scroll.
Reason 2: Quality can also be proven simultaneously
If you show only one piece of work, there is a risk that people will think, "Maybe they just happened to pick a good one." But if 100 pieces are lined up, that risk disappears. The uniformity of the overall quality itself becomes a message that says, "This person is a serious creator."
Reason 3: The aesthetics of alignment
Humans instinctively feel a sense of satisfaction when looking at regular patterns arranged in an orderly fashion. A "single image packed with images" is visually "satisfying" before you even think about the meaning. That is why it goes viral.
Tips for creating effective tile images
Tip 1: The more images, the stronger the impact
30 images are stronger than 10, and 100 are stronger than 30. The more images there are, the more the "pressure of quantity" is conveyed. Since this tool can arrange thousands of images in a few seconds, the right approach is to show everything without holding back.
Tip 2: Smaller sizes look better
Rather than making each image look large, packing them in smaller and denser creates more impact. The goal is not to have people read individual images, but to convey "quantity and overall atmosphere." I recommend setting the size slider to a smaller value to create a high-density tile.
Tip 3: Design the number of images according to the purpose
Features
🎁 Download (Try it for free 3 times)
How to use (3 steps)
Step 1: Download and launch the EXE
Save ImageGridViewer.exe from the "Download" button above. Saving it to your desktop makes it easy to find. Launch it by double-clicking. No installation is required, and it does not clutter the registry. When you are finished, simply delete the EXE and it will disappear without a trace.
When launching for the first time, you may see a warning saying "Windows protected your PC." This is a common warning for apps developed by individuals and is not a virus. You can launch it by clicking "More info" -> "Run anyway."
Step 2: Select a folder
Click the "📁 Folder" button on the screen and select the folder containing your images. You can also drag and drop a folder into the window. Even if there are subfolders, it will trace through all the contents to find the images (supports PNG, JPG, JPEG, WebP, GIF, and BMP).
Once the images are loaded, they will be packed onto the screen.
Step 3: Adjust and save as a screenshot
Adjust the appearance using the two sliders on the toolbar:
Count slider: Increase or decrease the number of images displayed
Size slider: Change the display size per image
Once it looks the way you want, press the "📸 Save Screenshot" button. A native save dialog will open, so specify the save destination folder and name to save. It will be exported as a 3x resolution PNG.
That's all there is to it. You can use it completely free for up to 3 times. The count is triggered only when you press the save screenshot button. It is not based on the number of launches or the number of images loaded. If you don't like it, just try it 3 times and delete the EXE. No costs will be incurred at all.
Who should try this 3 times
If any of the following apply to you, please give it a try. Even just with the 3 free uses, something is bound to change for you.
Those listing on Coconala or CrowdWorks: Just by creating one portfolio image, the impression of your listing page will change drastically
Instagram operators: Making end-of-month summary posts a habit leads to an increase in followers
Those generating large amounts of AI images: You will gain a "means of showing" 500 generated items by summarizing them into one image
Handmade artists: Just by turning your pinned profile image into a list of your works, your sales will change
Freelance designers and video editors: Updating your portfolio will become 10 times faster
Blog operators: You can differentiate the eye-catching image at the beginning of your articles
Those who "want to look back on this year's achievements at the end of the year": If you summarize a year's worth of images into one, it will be the best memento and SNS post
Even for uses not listed above, if you have the task of "lining up images," it will definitely be useful.
Display when used 3 times
A badge saying "Free trial: 3 / 3 uses remaining" will appear on the far right of the toolbar. Each time you use it, the count will decrease to "2 / 3 uses remaining" and "1 / 3 uses remaining," and when you try to press it for the 4th time, it will switch to the license key entry screen.
If you decide you don't need it anymore, just close the window. If you find it useful and want to keep using it, please proceed to the ¥1,480 purchase in the next chapter.
Notes on first launch
Windows may display a "Protected" warning. This is a common warning for apps developed by individuals and is not a virus. You can launch it by clicking "More info" -> "Run anyway."
Behind the scenes: Why I made it
I built this tool using Electron (Node.js + Chromium). Programming isn't my specialty, but I completed it over a weekend with Claude Code (AI assistant).
At first, I thought, "Anyone could make this," but once I released it, I received feedback like "This is incredibly useful" and "Why didn't this exist before?" and realized that tasks I thought were "obvious" were actually stealing time from many people.
Tools that solve small inconveniences are the ones that get used every day. I hope this tool becomes one of them.
Differences from other tools
Differences from online image combination services
If you search for "image combine," tons of free online tools will appear. However, most are at the "align 2-3 images" level and do not support 20 or more images. Furthermore, because you have to upload images, you cannot use them for images containing customer information or highly private photos. This tool processes everything locally, so not a single millimeter of your image data leaves your computer.
Differences from Photoshop's contact sheet feature
Photoshop has a "Contact Sheet" feature to list images in a folder, but it requires the full Photoshop app (from ¥2,728/month) and the operation is surprisingly complex. This tool specializes in high-density grids that look great on social media.
Differences from File Explorer screenshots
There is a method of taking screenshots in "Extra Large Icons" view, but it's full of problems like file names appearing, large gaps, low resolution, and inability to adjust sizes. I've received a lot of feedback saying, "Just not having file names show up is worth it alone."
If you like it, you can use it permanently for ¥1,480
If you try it 3 times and feel "This is useful!", you can purchase a license key for permanent use for a one-time payment of ¥1,480 (this is optional; you don't have to buy it if you don't like it).
💳 ¥1,480 one-time payment, no monthly subscription

From the 4th time onwards, a license key entry screen will appear. If you purchase it for ¥1,480 from the purchase page, you can continue using it immediately. If you decide you don't need it after using it 3 times, that's the end of it.
Q. Are images sent to the internet?
They are not sent at all. Everything is processed entirely within your PC. It works even without an internet connection.
Q. Can I use it on a Mac?
It is currently Windows-only.
Q. How many images can I load?
Operation has been verified for up to several thousand images.

Q. What if I lose my key after purchase?
If you let me know your PayPal payment email address, I will reissue it for you.
Post-purchase support
After your purchase, if you have any trouble with how to use it, bugs, or requests, please feel free to consult me via the note message function. As this is a solo project, my response speed is limited, but I will prioritize reflecting feedback from purchasers.
In the past, features like "right-click support" and "automatic password memory" were added based on purchaser requests. If you have any requests like "Can I do this?", I will include them in updates sequentially where possible.
Common Misconceptions
"You can do this in Canva, so why would I need this?"
Yes, you can do it in Canva. But the "time" it takes to create is different. Work that takes 15 minutes in Canva takes only a few seconds with this tool. The difference isn't "whether you can do it," but "how many minutes it takes." Even if you only use it once a month, you'll save over 3 hours a year.
"Isn't ¥1,480 expensive?"
It's cheaper than a month and a half of Canva Pro, and you can keep using it 3 years or 5 years from now without paying an extra yen. If you pay for Canva monthly, that's 36,000 yen over 36 months. With this tool, you pay once and you're done. It's the type of tool where "you get your money's worth the moment you use it."
"Is it too simple to be useful?"
It's precisely because it's simple that you can use it every time. Multi-functional tools have a high learning curve, and you end up not using them. This tool only has two steps: "select folder -> save." If you think of it as not having few features, but being focused only on the necessary ones, you'll understand the essence of it.
Finally
Are you melting away your time every month and every year on the tedious task of "neatly arranging images" without even realizing it?
You can replace the 15 minutes in Canva, 20 minutes in Photoshop, or the struggle of doing it manually with just a few seconds to select a folder.
Coconala operations, Instagram posts, handmade sales, blog writing, client proposals, AI image collections—these are all areas where "a single sheet with neatly arranged images" makes a difference. And just by streamlining that "arranging work," you can get back 10 to 30 hours of free time per year.
For many people, ¥1,480 is the price of one lunch or two convenience store trips. But that ¥1,480 will end the "15-minute portfolio tile image hell" that would otherwise continue forever.
If you use it once and find it convenient, you've already made your money back. Every use after that is pure time savings.
First, try it out for free 3 times. That alone will change your sense of time. You can decide whether to buy it after you've used it. I won't pressure you.
