WebP to WebM Optimization FAQ
Why convert an animated WebP to a WebM video instead of leaving it as is?
+
Video formats like WebM compress motion far better than animated image formats. A chunky animated WebP often shrinks dramatically as a WebM, plays more smoothly, and is accepted by platforms (timelines, ad systems, messaging) that reject animated images.
How small will the WebM be compared to the WebP?
+
Animated GIF and animated WebP are inefficient compared with a real video codec, so the WebM is frequently several times smaller for the same visible motion — one of the main reasons to make this conversion for web delivery.
Does the WebM video have sound?
+
No — image formats carry no audio, so the WebM starts silent. If you need a soundtrack, convert to WebM first, then add audio with a video editor; the conversion itself only handles the visual track.
Can I make a slideshow WebM from several WebP images?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Is the WebM good for uploading to social platforms?
+
Yes — an MP4 / WebM is exactly what timelines, stories, and ad systems expect, unlike an animated WebP that many of them downrank or reject. Pick the WebM container your target platform lists as supported.
How long does WebP to WebM take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Is my WebP file private during conversion?
+
Yes. Uploaded WebP 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.
