Upload the WebM file and our converter samples frames (default 15 fps), encodes them into an animated GIF container, and applies palette quantization tuned for the GIF format (GIF GIF uses an adaptive 256-color palette; animated WebP supports full 24-bit color).
How short / long should my WebM be for a good GIF?
+
Animated GIF is best for clips under 10 seconds. Longer than that and the file balloons (animated GIF is uncompressed-per-frame); use GIF WebP or APNG for longer animations, both of which compress similarly to video codecs.
What is the file size of a 5-second GIF animation from a WebM 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 GIF have the same frame rate as the WebM?
+
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 GIF animation have audio?
+
No — animated GIF formats (GIF, WebP, APNG) do not store audio. If you need sound, target a video format (MP4, WebM) instead of GIF.
Can I make the GIF animation loop?
+
Yes — the loop count option controls whether the GIF loops infinitely (default), plays N times, or plays once. Loop info is stored in the GIF container metadata and respected by most viewers.
Why does my GIF look choppy compared to the WebM?
+
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 WebM before making the GIF?
+
Yes — the resize option scales the input down before frame extraction, which dramatically reduces final GIF size. A 480p GIF from a 4K WebM is 16× smaller than a 4K GIF. Crop is handled in a separate /video-cutter/ step.
Is my WebM private during GIF conversion?
+
Yes — same privacy model as every conversion. Source and output are isolated and deleted within minutes.
How long does the WebM to GIF conversion take?
+
Animated GIF 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 GIF preserve transparency from the WebM?
+
Animated GIF supports single-color transparency only (binary mask). Animated WebP and APNG support full alpha. WebM sources that have no alpha channel (most camera footage) produce fully-opaque GIF regardless of format.
Can I share the GIF on Discord / Slack / Twitter?
+
Yes — animated GIF 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.
