# Image Combiner

Combine several images into one, stacked or side by side, with an optional gap. Different widths are scaled or padded, never distorted. Nothing is uploaded.

## Capabilities

- Free: Yes, with no watermark and no page limit.
- Account required: No. There is no account system.
- Processed on device: Yes. The file is read by your browser and never uploaded. There is no server to send it to.
- Formats: JPG, PNG and WebP in. PNG or JPG out. PNG keeps transparency and loses nothing; JPG is smaller.
- Limits: No image count limit. The ceiling is the largest canvas your browser will encode, and a combination that goes over it is refused with the size it would have been, not saved broken.
- Mobile: Yes, on any modern mobile browser. Large files are limited by the memory the phone gives the browser.
- Offline: Yes, after you have used it once. Your browser keeps what the tool needs, so it then works with no network connection.

## Questions

### What happens if my images are different widths?

You choose. Scale to match shrinks every image to the narrowest one in the set, keeping each one's shape, so nothing is stretched and nothing is enlarged. Keep sizes, pad leaves every image at its own size and fills the leftover space with a background colour you pick. Whichever you choose, no image is ever distorted to fit.

### Can I put the images side by side instead of stacked?

Yes, that is the Side by side option. Stacked is the default because the common job is joining phone screenshots into one tall picture. Side by side works the same way, matching heights instead of widths.

### Does combining reduce quality?

Saving as PNG does not: it is lossless, and images that are not being scaled are drawn pixel for pixel. Saving as JPG re-encodes everything, which costs a little and gives you a much smaller file. Scaling to match a narrower image does lose the detail it removes, which is why the tool never scales the other way.

### Does the order of the images matter?

Yes, and you set it. The arrows under each thumbnail move an image earlier or later, and the number on it is where it will land: first is the top when stacked, and the left when side by side.

### Can I leave a gap between the images?

Yes: none, 8, 16 or 32 pixels, filled with the background colour. The gap goes between neighbours only, never at the outer edges, so the combined picture has no border.
