Choose files and settings to create output images.

Files are processed only on this device and are never uploaded to a server. How it works

Set the order and layout, then combine images

Select up to 12 images and use the up and down buttons to change their order. Choose vertical, horizontal or grid layout, a gap from 0 to 200 px and 1 to 6 grid columns. Each image is centered in a cell sized to the largest source width and height, without stretching or cropping.

Different source sizes leave blank space inside cells. Choose a white or transparent background; JPG always uses white. If the combined result exceeds an 8,192 px side or 24 million pixels, processing fails. Use smaller source images or another layout.

Supported files and limits

Input supports JPG, PNG and WebP, up to 20 MB per file and 12 files, with at most 8,192 px per side and 24 million pixels. Output has the same pixel limits. Only the first animation frame is processed; metadata is not retained. HEIC, SVG and GIF are unsupported. Worker and OffscreenCanvas browser support is required. The output is not guaranteed to meet passport, ID photo or institutional submission requirements.

The combined input limit is 50 MB and 24 million pixels. Output files are limited to 50 MB in total. The entire input size and pixel count are checked before decoding.

Frequently asked questions

Why is an image rejected?

Unsupported formats, damaged files, size or pixel limits, or missing browser features can cause rejection. Limited device memory may cause failure even within these limits.

What happens when I cancel?

Cancel terminates the processing Worker. Selected source files remain so you can change settings and retry. Selecting new files replaces the current list.
