How to check the result
Compare the source and output previews, then check dimensions, frame count, duration, and file size to confirm that the chosen settings took effect.
The preview is a quick check. Treat the downloaded file, re-parsed for structure and timing, as the final result.

Method and calculation
The tool reads each frame in this browser, applies the selected Wavy-Edge GIF Generator settings, and encodes the result as a GIF.
Boundaries and limitations
Large files or animations with many frames need more memory and may take longer. Check the downloaded GIF in a second player before sharing it.
Privacy and local processing
The GIF is read, decoded, processed, previewed, and encoded in this browser. Nothing is uploaded, no third-party runtime API is called, and the input is not saved.
Format and standards
GIF parsing and output follow the GIF89a format description. Very short delays, loops, and color quantization can look different across browsers and players.
Frequently asked questions
How do I add a wavy edge to a GIF?
Upload a GIF, adjust the wave peaks, amplitude and phase, then process it to preview the new edge locally in your browser.
Does this tool upload my GIF?
No. Your source GIF and the generated animation remain in the browser, and the finished file is downloaded only when you choose Download.
