GIF to WebM Conversion FAQ
Will the animation loop like the GIF did?
+
Looping is a player behaviour rather than a stored property once you are in video, so set the loop attribute on your video element or enable loop in the player. Social platforms loop short clips automatically.
What happens to the frame rate?
+
Frame timing is read from the source and reproduced as closely as the target allows. Animations with irregular per-frame delays are normalised to a constant frame rate, which usually looks smoother than the original.
Will the colours change?
+
They can improve. A palette-limited source is restricted to 256 colours, and video codecs are full-colour, so banding in the source stays but no new banding is introduced. Where WebM is the royalty-free web container — VP9 or AV1 video with Opus audio, decoded natively by every modern browser, the conversion generally makes gradients look better, not worse.
Is there audio in the output?
+
No — the source has no sound, so the WebM is silent. Some platforms prefer a video to have an audio track; add a silent or music track afterwards if a specific platform complains.
What resolution will the WebM be?
+
The source dimensions by default. Note that some codecs require even-numbered dimensions, so an odd-sized source is padded or cropped by a single pixel — harmless, but it explains an unexpected off-by-one in the output size.
Which target should I choose for social media?
+
MP4 with H.264 is accepted everywhere and is the right default. WebM is smaller and ideal for self-hosted web embedding but is rejected by several social platforms.
Can I trim or crop during the conversion?
+
Not in the same pass — convert first, then use /video-trim/ on the result. Doing it in two steps is faster than re-encoding the whole clip just to change its boundaries.
Is my file private during conversion?
+
Yes. Uploaded GIF files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted WebM are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
