How to convert WebM to GIF
- 1
Drop your WebM file into the converter above, or click to browse. Nothing is uploaded — the file stays on your device.
- 2
Adjust the settings (width, frame rate, and trim). Tip: For screen recordings, 640px width at 10–12 fps keeps interface text readable while keeping the GIF lightweight.
- 3
Click “Convert to GIF”. The conversion runs locally in your browser — larger files take longer, and a progress bar keeps you posted.

Why convert WebM to GIF?
Browser-based screen recorders almost universally export WebM, but the places you want to show a quick demo — GitHub READMEs, Jira tickets, Notion docs, code reviews — render GIFs inline and autoplay them. Converting bridges that gap in one step.
The converter builds a custom color palette from your recording before encoding, which keeps UI screenshots and text crisp — exactly what naive GIF converters get wrong with screen content.
WebM vs GIF at a glance
| WebM | GIF | |
|---|---|---|
| Type | Video container (VP8/VP9 + Opus) | Animated image |
| Compression | Lossy, efficient, royalty-free | Lossless per frame, 256-color palette |
| Transparency | — | Yes (1-bit) |
| Audio | Yes (Opus/Vorbis) | No |
| Compatibility | All modern browsers; weak in editors and on Apple devices | Universal — autoplays in chats, docs, emails |
| Best for | Web embeds, HTML5 video, screen recordings | Short loops, reactions, tutorials, README demos |
About the formats
WebM WebM (VP8/VP9 + Opus)
WebM is the open, royalty-free video format built for the web, using the VP8/VP9 codecs with Opus or Vorbis audio. Browsers and screen recorders love it — Chrome extensions and many capture tools export WebM by default — but desktop editors, iPhones, and smart TVs often refuse to open it.
GIF Graphics Interchange Format
GIF is the internet's animation workhorse: it autoplays silently everywhere — chat apps, docs, README files, emails — with no video player needed. The trade-offs are a 256-color palette, no audio, and file sizes that grow quickly with resolution and frame rate.
Frequently asked questions
How do I make a GIF for a GitHub README?
Record your screen (most browser recorders give you a WebM), drop it here, trim to the interaction you want to show, set width to 640px and about 10 fps, then convert. Drag the resulting GIF into your README on GitHub and it embeds and autoplays.
Will small text stay readable in the GIF?
Yes, if you don't downscale too far — GIF is lossless per frame, so text stays sharp at the pixel level. Keep the width as high as your file-size budget allows (640–800px for dense UIs) and text will remain legible.
Is this WebM to GIF converter really free?
Yes — completely free, with no watermarks, no sign-up, and no conversion limits. The tool is supported by ads on this page, so the converter itself never asks you for anything.
Are my files uploaded to a server?
No. This converter runs entirely in your browser using WebAssembly (a browser build of FFmpeg). Your WebM file never leaves your device — nothing is uploaded, stored, or seen by us, which also makes it safe for private or confidential files.
Is there a file size limit?
There's no hard limit. Because conversion happens on your own device, the practical ceiling is your browser's memory — files up to a few hundred megabytes work well on most computers. Very large files may be slow or fail on low-memory devices.
Why does the first conversion take a moment to start?
The first time you convert, your browser downloads the conversion engine (about 31 MB) once. It's cached after that, so later conversions start instantly — and they keep working even offline.
