MP4 به WebP سوالات متداول تبدیل
How do I turn a MP4 video into an animated WebP?
+
Upload the MP4 and the converter samples frames (default 15 fps), encodes them into the animated WebP container, and applies palette quantization tuned for the WebP format (GIF gets an adaptive 256-color palette; animated WebP supports full 24-bit color).
How short should my MP4 clip be for a clean WebP animation?
+
Animated WebP works best for clips under 10 seconds. Beyond that the file balloons (GIF is essentially per-frame uncompressed). For longer animations target animated WebP or APNG, both of which use video-codec-grade compression and scale much better.
What file size should I expect from a 5-second MP4 → WebP?
+
Animated GIF: 2 to 8 MB at 480p depending on motion complexity. Animated WebP: 200 KB to 1 MB at the same resolution / quality. Animated WebP is 5 to 10x more efficient than GIF for the same visual quality.
Will the WebP animation have the same frame rate as the MP4?
+
By default we downsample to 15 fps for animated GIF (it visually struggles above 25 fps) and 24 fps for animated WebP / APNG (which handle higher rates cleanly). Override via the frame-rate option if your viewer supports the source rate.
Will the WebP animation play audio from the MP4?
+
No — animated WebP formats (GIF, WebP, APNG) do not store audio. If you need sound, target a video container (MP4, WebM) instead of an animated image format.
Can I make the WebP animation loop forever?
+
Yes — the loop-count option controls whether WebP loops infinitely (default), plays N times, or plays exactly once. The loop count is stored in the WebP container metadata and respected by every modern viewer.
Why does my WebP look choppy compared to the MP4 source?
+
Two common causes. First, frame-rate downsampling: 15 fps WebP from a 60 fps MP4 drops 75% of frames; fix with the frame-rate slider. Second, palette quantization: GIF is limited to 256 colors and gradient-heavy MP4 dithers visibly. Switch to animated WebP for full-color fidelity.
Can I crop or resize the MP4 before making the WebP?
+
Yes — the resize option scales the MP4 down before frame extraction, which dramatically shrinks WebP file size. A 480p WebP from a 4K MP4 is roughly 16x smaller than a 4K WebP. Use /video-cutter/ for cropping in a separate step.
Is my MP4 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.
How long does converting a 10-second MP4 into WebP take?
+
Animated WebP encoding is CPU-bound and slower than typical video re-encode — expect roughly 1x source duration. A 10-second MP4 → 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 MP4?
+
Animated GIF supports single-color transparency only (binary mask, no alpha gradient). Animated WebP and APNG support full alpha. MP4 sources without an alpha channel (most camera footage) produce fully-opaque WebP regardless of target format.
Can I share the resulting WebP on Discord, Slack, and Twitter?
+
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, pick GIF; if file size matters, pick WebP.
