Question 1

How many images can I merge?

Accepted Answer

There is no fixed limit, but very large images or dozens of files may hit browser memory limits. For best results, use a handful of reasonably sized photos (under a few megabytes each). The tool shows an error if the combined output exceeds safe pixel dimensions.

Question 2

What layout options are available?

Accepted Answer

Side by side aligns all images to the same height; stacked aligns them to the same width; grid arranges images in two columns left-to-right, top-to-bottom. Reorder thumbnails before merging to control the final sequence.

Question 3

Can I merge images with transparent backgrounds?

Accepted Answer

Yes. PNG and WebP images with alpha channels keep transparency where pixels are transparent. The background color fills any gap between images and any letterboxing in grid mode — set it to white or match your design.

Question 4

What output formats can I download?

Accepted Answer

PNG (lossless, supports transparency), JPEG (smaller files, no transparency), or WebP (good compression with optional transparency). Use PNG for graphics with transparency; JPEG for photo collages where file size matters.

Question 5

Is my image uploaded to a server?

Accepted Answer

No. Merging uses the Canvas API entirely in your browser. Your images never leave your device.
