A modern browser with canvas support
The editor uses standard canvas rendering for preview, PNG and GIF. Current desktop browsers are the easiest place to start. Mobile browsers can use the same tools, but memory and background-tab behavior vary.
Video support is detected, not assumed
MediaRecorder and canvas capture support determine whether video export is available. If your browser cannot encode video, PNG and GIF remain available. Try a current desktop browser if video is essential.
Keep the workload reasonable
A large uploaded photo, a long animation and several open browser tabs all compete for memory. Use a shorter duration and a smaller source image if the device struggles. The editor accepts up to 10 MB and limits decoded images to 16 megapixels.
No account needed for the local workflow
Input images, preview, project files and downloads are handled in the current browser. Clearing browser data removes the local saved state. Download a project file when you want a copy independent of that browser.
