How to Use
- Load 2 or more images using “Add Images” or drag & drop.
- Use the up/down buttons or drag the image cards to set the order: top to bottom for vertical merging, left to right for horizontal merging.
- Choose Vertical, Horizontal, or Grid in the direction setting. For Grid, set the number of columns as well.
- Adjust size fit, alignment, background color, and gap, then check that the spacing and edges look right.
- Click “Update Preview” to check the result, then save as PNG / JPEG / WebP.
Notes
- Images are processed entirely in the browser and are never sent to any server.
- Useful for joining tall screenshots, comparing images side by side, or making a simple image grid for social posts.
- With “Keep original size”, images are not scaled — empty areas are filled with the background color.
- The quality slider affects JPEG and WebP exports. PNG export does not use the quality setting.
- Merging many large images may take time depending on your device’s memory.
Frequently Asked Questions
How do I join iPhone screenshots into one tall image?
Add the screenshots you want to join, then press “Join vertically (no gap)” at the top. Reorder them with the up/down buttons in the image list, check the preview, and save as PNG or JPEG.
I want to join images seamlessly with no gap
Use the “Join vertically (no gap)” preset, or set the “Gap between images” slider to 0px. The images will look like one continuous picture.
Are my images uploaded to a server?
No. Everything is processed in your browser with the Canvas API, and your images are never sent to any external server.
I can’t add HEIC photos
HEIC files cannot be read in browsers other than Safari on iPhone or Mac (for example, browsers on Windows). Please convert them to JPEG first. Note that iPhone screenshots are PNG, so they can be joined as is.
Images of different widths leave empty space on the sides
Under “Size fit”, choose “Match the largest” or “Match the smallest” so the widths align and the empty space is reduced. Images are scaled while keeping their aspect ratio.
How do I place photos side by side for a comparison image?
Add two or more photos and press “Side by side” at the top to merge them into one horizontal image. If their heights differ, choose “Match the largest” under “Size fit” to align them — handy for before/after shots and product comparisons.
Do I need to install an app?
No. The tool runs free in your browser on both smartphones and PCs. Everything is processed on your device, so unlike an app there is no need to grant access to your photo library.
