Max frame rate

Default 10 fps is a cap, not a guarantee. Past ~50 MB or too many frames, it steps down fps → long edge → duration.

Cap 10 fps

Longest edge

Scale by the longer side, keep aspect ratio, never larger than the source.

GIF vs animated WebP

Both paths share the same clip, speed and width controls — only the final container differs. This page writes animated WebP by default.

Compatibility

Animated GIF

  • Works in chat apps, forums and email almost everywhere
  • At most 256 colours — photos can look muddy
  • Often heavier at the same clarity
  • Transparency is all-or-nothing

Size

Animated WebP

  • Modern browsers and most websites support it
  • True colour — usually cleaner than GIF
  • Often lighter for the same clip, with better semi-transparency
  • Old software or some apps may not open it

FAQ

Are my files uploaded to a server?

No. This page has no upload channel — files are read, converted and saved entirely on your device. It even works offline.

Is it really free?

Yes. Every conversion path is free with no sign-up, no usage caps and no watermarks.

Will the quality suffer?

Lossy targets (MP3, JPEG, H.264…) re-encode at the quality you choose; lossless targets keep every pixel. Keep the defaults if unsure.
