🎬 Video to Animated WebP Converter

Animated WebP is a modern image format developed by Google that supports both lossy and lossless compression for animated images. Compared to GIF, animated WebP files are typically 25-35% smaller at equivalent quality, support 24-bit color with alpha transparency (vs GIF's 256 colors), and offer smoother gradients. It's supported by all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. For websites, switching from GIF to animated WebP can significantly improve page load times and reduce bandwidth usage.

Our tool supports all common video formats including MP4, WebM, MOV, AVI, MKV, FLV, and WMV. The FFmpeg engine can handle virtually any video codec. For best results, we recommend using MP4 (H.264) or WebM (VP8/VP9) files as they are most widely compatible and offer efficient compression. The maximum recommended file size is 100 MB for optimal browser performance.

The ideal frame rate depends on your use case: 8-10 fps is great for memes, stickers, and simple animations (smallest file size); 12-15 fps works well for screen recordings, tutorials, and UI demos; 20-30 fps is best for smooth motion like short video clips or cinemagraphs. Remember: higher frame rates mean larger file sizes. For web usage, 10-15 fps usually provides an excellent balance of smoothness and file size.

No — everything happens locally in your browser. Your video never leaves your device. All processing is done using WebAssembly (FFmpeg) or the Canvas API directly in your browser. This means your files remain 100% private and secure. There's no file upload to any external server, making this tool ideal for sensitive or confidential video content. You can use it offline after the initial page load.

FFmpeg WASM is the full-powered engine that generates genuine animated WebP files (.webp) with true animation support — just like a GIF but in WebP format. It requires downloading ~30MB of WebAssembly on first use (cached thereafter). Canvas mode is a lightweight fallback that extracts individual frames from your video as separate WebP images and plays them in a preview loop. Canvas mode works instantly without any downloads. For production use, we recommend the FFmpeg engine for true animated WebP output.

For web use, we recommend keeping the width between 400-800 pixels. A width of 480px is a sweet spot for social media and messaging platforms. For smaller UI elements like stickers or emojis, 200-300px is sufficient. The height is automatically calculated to maintain your video's original aspect ratio. Larger dimensions dramatically increase file size — a 1200px wide animated WebP can be 4-5x larger than a 480px version with similar quality settings.

Setting the loop count to 0 (Infinite) makes your animated WebP play continuously without stopping — perfect for memes, stickers, and website animations. Setting it to 1 means the animation plays once and stops on the last frame. Values from 2-10 play the animation that many times and then stop. Most use cases benefit from infinite looping (0), but finite loops can be useful for tutorial animations or loading indicators.

Several factors affect file size: resolution (higher = bigger), frame rate (more fps = bigger), quality setting (higher quality = bigger), and video duration (longer = bigger). To reduce file size: lower the output width to 320-480px, reduce the frame rate to 8-10 fps, lower quality to 60-70, or trim your video to a shorter clip before converting. Animated WebP is still significantly smaller than GIF at equivalent settings.
