How to use this image tool
- Choose the source images.
- Set the available options for the output.
- Select “Create mosaic” and inspect the result.
- Download the newly generated file.
Arrange several photos into one evenly spaced mosaic. Choose the columns, tile size, gap, background, and crop behavior, then export the composed canvas.
Images are scaled into equal tiles, cropped or contained as selected, and composited onto one canvas.
Processing stays in the current browser tab. Closing or resetting the page releases temporary preview URLs.
The file picker accepts the formats shown above. Actual decoding support is controlled by the browser. Images above 60 megapixels are blocked to reduce memory crashes, and canvas-generated output does not retain source metadata.
| Stage | Behavior |
|---|---|
| Input | Browser-decoded image files |
| Processing | Local Canvas, File, and Blob APIs |
| Output | New downloadable result |
No. Processing runs in your browser. The page does not send the selected image to a processing server.
The tool accepts the formats listed on the page, but decoding still depends on your browser. AVIF and some unusual files may not open in older browsers.
Canvas-generated image outputs normally omit EXIF and other source metadata. The batch rename tool copies original bytes, while its ZIP changes filenames only.
The tool rejects images above its pixel safety limit because large canvases can exhaust memory, especially on phones. Resize the source first if needed.
Yes. The download is a newly generated image or report. Check the preview and dimensions before publishing or archiving it.
