How It Works
Drop or select your GIF file
Click the upload area above or drag your .gif file onto it. Files up to 50 MB are supported. The GIF loads directly into your browser — nothing is sent to any server.
Wait 2–5 seconds while FFmpeg converts it
The converter runs FFmpeg compiled to WebAssembly entirely in your browser tab. It reads every frame of your GIF, applies H.264 video encoding, and muxes the result into an MP4 container — all locally on your device.
Click Download to save your MP4
The output file is an H.264-encoded MP4 with the same dimensions and frame timing as the source GIF. It will loop automatically when played in a browser using the loop attribute, and is ready to upload directly to Instagram Reels, TikTok, YouTube Shorts, or any video platform.
Why Convert GIF to MP4?
GIF is a relic of 1987 web technology. Every frame in a GIF is stored as a complete, independently compressed image using LZW compression — there is no concept of inter-frame similarity. That means a 5-second animation at 15 FPS stores 75 full images. A typical GIF weighs 3–15 MB. The same animation as an H.264 MP4 weighs 150–400 KB — an 80–95% reduction in file size with identical or better perceived quality. Smaller files load faster, consume less bandwidth, and score better on Google's Core Web Vitals assessment, directly improving your Largest Contentful Paint (LCP) metric.
Google's PageSpeed Insights has explicitly flagged animated GIFs as a performance issue since 2019, recommending replacement with MP4 or WebM. The audit rule "Use video formats for animated content" penalizes GIF usage and offers MP4 conversion as the fix. Replacing even one large animated GIF on a landing page can improve mobile LCP by 500 ms or more, which directly affects your Google Search ranking via the Core Web Vitals signal.
Beyond web performance, MP4 is simply the universal standard for video on social platforms. Instagram, TikTok, YouTube, Twitter/X, Facebook, and LinkedIn all accept MP4 uploads but do not accept GIF files (or severely downgrade them). Converting your GIF to MP4 unlocks every major distribution channel simultaneously, with no visual quality loss.
Instagram Reels and Stories: Instagram does not support GIF uploads at all. Any animated content must be submitted as an MP4 or MOV. Converting your animated GIF to MP4 lets you post it as a Reel or Story without re-creating the animation in a video editor.
Website hero sections and landing pages: If you have an animated GIF in a hero section, replacing it with an autoplay muted looping MP4 (<video autoplay muted loop playsinline>) can reduce page weight by 90% and eliminate the LCP penalty. This is one of the highest-ROI web performance improvements available.
Email marketing: While GIF has broad email client support, large GIFs are frequently blocked by corporate email filters due to file size. Converting to MP4 and hosting the video externally — linking to it from a static preview image — is the professional approach for video in email campaigns.
App store previews and product demos: Apple App Store and Google Play require MP4 preview videos. If you created a demo animation as a GIF, converting it to MP4 is the first step toward a polished app store listing.

Technical Details
This tool runs FFmpeg compiled to WebAssembly (Wasm) — the same FFmpeg binary used in professional video production workflows, running entirely in your browser tab. When you drop a GIF, FFmpeg reads the file's frame index, extracts each frame as a raw image, and feeds the frame sequence to the libx264 encoder. H.264 (the codec inside MP4) uses a combination of I-frames (complete key frames) and P-frames (delta frames that store only what changed from the previous frame). Because most frames in a looping animation share large regions of identical pixels, P-frame compression is extremely efficient — hence the 90%+ size reduction.
The output is wrapped in an MP4 container (MPEG-4 Part 12) and uses the yuv420p pixel format for maximum compatibility with players, social platforms, and operating systems. The -movflags +faststart flag is applied so the metadata is written at the beginning of the file, enabling progressive streaming from CDNs — the video starts playing before the full file downloads.
