Yes — the resize option scales the WebM down before frame extraction, which dramatically shrinks WebP file size. A 480p WebP from a 4K WebM is roughly 16x smaller than a 4K WebP. Use /video-cutter/ for cropping in a separate step.
Is my WebM video private during WebP animation creation?
+
Yes — same privacy model as every conversion. Source video and animated WebP output are processed in isolated workers and deleted within minutes; no human review, no retention beyond the result download window.
转换一个10秒的 WebM 成 WebP 需要多长时间?
+
Animated WebP encoding is CPU-bound and slower than typical video re-encode — expect roughly 1x source duration. A 10-second WebM → WebP finishes in about 10 seconds; a 30-second clip in about 30. GIF is slightly slower than animated WebP due to palette computation.
Does the WebP animation preserve transparency from the WebM?
