Converts in your browser — nothing uploaded
How It Works
Select or drop your GIF file
Click the upload zone or drag your .gif file onto it. Files up to 50 MB are supported. The GIF is read directly into your browser's memory — nothing is sent over the network at any point during the process.
Choose your output format: MP4 or WebM
Select MP4 for maximum platform compatibility — it works on every social network, device, and browser. Choose WebM for the open-codec alternative that produces slightly smaller files and is ideal for embedding on websites targeting Chrome and Firefox users.
Download your video and publish anywhere
FFmpeg WebAssembly converts the GIF locally in 2–8 seconds. The finished file preserves your original frame dimensions and timing. Download it and upload directly to Instagram, TikTok, YouTube, or drop it into a web page with a video tag for a lightweight looping animation.
Why Convert GIF to Video?
GIF is a format frozen in 1987 technology. Its LZW compression encodes every single frame independently with no reference to adjacent frames, and it caps every frame at just 256 colors. The result is predictably large files: a typical five-second looping animation at 15 fps stores 75 independently compressed images and weighs 4–12 MB. Modern video codecs solve this by encoding only the differences between frames. A static background shared across 50 frames is stored once as a keyframe and referenced cheaply by every subsequent frame. The same five-second loop drops to 150–400 KB as an MP4 or 100–300 KB as a WebM — a size reduction of 80–97%.
The format-agnostic phrase "GIF to video" reflects a real choice: different use cases call for different output formats. MP4 (H.264) is the safest universal choice — every browser, mobile device, social platform, and video editor on the planet reads it without configuration. WebM (VP9) is the open-codec alternative favored by web developers who want smaller files and no licensing concerns. Chrome, Firefox, Edge, and Android all play WebM natively; Safari and iOS support it as of Safari 14.1. Choosing between the two depends on where your video will live and who your audience is.
Google's Lighthouse performance auditing tool flags animated GIFs by name under the rule "Use video formats for animated content" and counts them as a performance defect. The Largest Contentful Paint (LCP) metric — a Google Core Web Vitals signal that factors directly into search rankings — is harmed by large GIFs above the fold. Replacing an 8 MB hero GIF with a looping MP4 or WebM video element typically cuts LCP by several hundred milliseconds on mobile, which improves both user experience and organic search visibility.
Social and messaging platforms have largely abandoned GIF support at the upload level. Instagram, TikTok, YouTube Shorts, Facebook Reels, and LinkedIn all require MP4 for video posts. Slack, Discord, and WhatsApp technically accept GIF files for short reactions, but for high-quality animated content intended as a video post, MP4 is required. Converting your GIF to video unlocks every distribution channel simultaneously, without recreating the animation from scratch.
Editing and archiving: Video files are first-class citizens in every editing timeline — from DaVinci Resolve and Premiere Pro down to iMovie and CapCut. A GIF-to-video conversion gives you a proper working file you can trim, color grade, add audio to, or re-export at any resolution. The resulting video is also dramatically easier to version, store, and retrieve at scale compared to a collection of GIF files with no metadata.
Key Features
Fully Private — Zero Uploads
Your GIF never touches a server. FFmpeg runs in your browser tab via WebAssembly. No file is ever transmitted anywhere — suitable for confidential assets.
Choose MP4 or WebM Output
Select the format that fits your target platform. MP4 for universal compatibility; WebM for open-codec web publishing with slightly smaller file sizes.
80–97% Smaller Files
Inter-frame video compression reduces a 10 MB GIF to under 400 KB in MP4 or under 300 KB in WebM with no visible quality loss.
Converts in Seconds
Most GIFs convert in 2–8 seconds. No queue, no wait, no server round-trip. The conversion speed is limited only by your CPU.
Ready for Every Platform
MP4 output uploads directly to Instagram Reels, TikTok, YouTube Shorts, Twitter, and LinkedIn. WebM output embeds perfectly in Chrome and Firefox.
Works Offline
Once the page has loaded, conversion keeps working even if your internet connection drops. No server dependency at runtime.

Technical Details
The conversion runs on FFmpeg compiled to WebAssembly (Wasm) — executing entirely inside a browser sandbox. For MP4 output, FFmpeg reads the GIF's frame index table, extracts each frame as raw pixel data, and encodes the sequence using libx264, the reference H.264 encoder. H.264 divides the frame sequence into I-frames (complete keyframes) and P-frames (predictive frames encoding only pixel differences from the previous frame). Because looping animations share large regions of unchanged pixels, P-frame compression is extremely effective — this is why file size drops so dramatically. The output is muxed with yuv420p pixel format and -movflags +faststart so players and CDNs can begin streaming before the full file downloads.
For WebM output, the same FFmpeg pipeline encodes using libvpx-vp9, Google's open-source VP9 codec. VP9 typically achieves 20–30% better compression than H.264 at equivalent visual quality, which is why WebM files are slightly smaller than their MP4 counterparts. VP9 is royalty-free and is the codec behind YouTube's adaptive streaming. The trade-off is slightly longer encode time and limited support on older Apple devices (pre-Safari 14.1). Both output formats use the same source frame data and produce visually identical results.
Both output paths preserve the original frame dimensions from the GIF source without upscaling or downscaling. Frame timing is derived from the GIF's per-frame delay values, so variable-speed GIFs with uneven frame durations are converted accurately. The pixel aspect ratio is always 1:1 square pixels, which is required for correct display on all modern platforms. No metadata, EXIF data, or identifying information is added to the output file — the video contains only the encoded frame data and the container headers required for playback.
