Upload the MOV file and our converter samples frames (default 15 fps), encodes them into an animated WebP container, and applies palette quantization tuned for the WebP format (WebP GIF uses an adaptive 256-color palette; animated WebP supports full 24-bit color).
How short / long should my MOV be for a good WebP?
+
Animated WebP is best for clips under 10 seconds. Longer than that and the file balloons (animated GIF is uncompressed-per-frame); use WebP WebP or APNG for longer animations, both of which compress similarly to video codecs.
What is the file size of a 5-second WebP animation from a MOV clip?
+
For animated GIF: 2-8 MB at 480p, depending on motion complexity. For animated WebP: 200 KB to 1 MB at the same resolution / quality — animated WebP is 5-10x more efficient than GIF.
Will the WebP have the same frame rate as the MOV?
+
By default we downsample to 15 fps for animated GIF (the format works poorly above 25 fps) and 24 fps for animated WebP / APNG (which handle higher rates fine). Override the frame-rate option to keep the source rate if your viewer supports it.
Will the WebP animation have audio?
+
No — animated WebP formats (GIF, WebP, APNG) do not store audio. If you need sound, target a video format (MP4, WebM) instead of WebP.
Can I make the WebP animation loop?
+
Yes — the loop count option controls whether the WebP loops infinitely (default), plays N times, or plays once. Loop info is stored in the WebP container metadata and respected by most viewers.
Why does my WebP look choppy compared to the MOV?
+
Two common causes: frame rate downsampling (15 fps GIF vs 30 fps source — fix with the frame-rate option) and palette quantization on GIF (only 256 colors — switch to animated WebP for full color fidelity).
Can I crop or resize the MOV before making the WebP?
+
Yes — the resize option scales the input down before frame extraction, which dramatically reduces final WebP size. A 480p WebP from a 4K MOV is 16× smaller than a 4K WebP. Crop is handled in a separate /video-cutter/ step.
Is my MOV private during WebP conversion?
+
Yes — same privacy model as every conversion. Source and output are isolated and deleted within minutes.
How long does the MOV to WebP conversion take?
+
Animated WebP encoding is CPU-bound and slower than typical video re-encode — expect about 1× source duration. A 10-second clip finishes in ~10 seconds.
Does the WebP preserve transparency from the MOV?
+
Animated GIF supports single-color transparency only (binary mask). Animated WebP and APNG support full alpha. MOV sources that have no alpha channel (most camera footage) produce fully-opaque WebP regardless of format.
Can I share the WebP on Discord / Slack / Twitter?
+
Yes — animated WebP GIF is universally supported. Animated WebP plays on Twitter, Discord and modern browsers but not on iMessage or older Slack clients. If maximum compatibility matters, target GIF; if file size matters, target WebP.
