Frequently Asked Questions

Images can be merged by drawing them onto a shared canvas element using HTML5 Canvas API and exporting the result as a single image file. The images can be arranged side by side, stacked vertically, or overlaid.

JPEG, PNG, WebP, and GIF frames are commonly supported for merging operations. The output format is typically PNG to preserve transparency or JPEG for smaller file sizes when transparency is not needed.

Merging images to PNG preserves full quality for the compositing step. Exporting the merged result as JPEG introduces compression artifacts, so PNG output is recommended when quality is a priority.
