Video to WebP Converter
Convert short video clips to animated WebP format directly in your browser. Create lightweight looping animations without uploading files to any remote server.
MP4, WebM, MOV, MKV, AVI, FLV, 3GP · up to 1 GB
Tips
- A 30 MB processing engine downloads once on your first visit and runs locally offline thereafter.
- Keep video clips under ten seconds because animated WebP files grow rapidly with duration.
- Dropping the source frame rate to 15 frames per second cuts final file payload roughly in half.
How to use it
- 1 Select or drag your source video file into the designated conversion area.
- 2 Adjust your target frame rate and output dimensions to control file size.
- 3 Start the conversion process and allow the browser engine to encode the frames.
- 4 Save the completed animated WebP file directly to your local drive.
What you should know
Web publishers and app developers frequently replace heavy GIF animations with animated WebP files to slash payload sizes while preserving 24-bit RGB color depth and 8-bit alpha channels. Unlike legacy GIF files limited to 256 indexed colors, animated WebP uses VP8 intra-frame and inter-frame predictive encoding. This delivers smooth gradients, eliminates visual dithering artifacts, and produces file sizes typically sixty to eighty percent smaller than equivalent GIF loops. Modern browsers across desktop and mobile platforms natively decode animated WebP without needing embedded video player controls or autoplay permission prompts.
This converter transcodes standard video containers like MP4, WebM, and MOV into animated WebP sequences entirely inside your browser tab using WebAssembly. The transformation discards the audio stream completely because the WebP container specification supports visual data exclusively. Since encoding runs on a single CPU thread without server offloading, long clips with high frame rates require extended processing times. For optimal balance between motion clarity and bandwidth efficiency, compress shorter highlights, trim excessive silent footage, and lower frame rates before exporting your final asset.
Frequently asked questions
Does the animated WebP file include audio from my original video?
No, the WebP format does not support audio tracks, so all sound channels are stripped during encoding.
Why does the conversion take longer for high-resolution video clips?
The WebAssembly encoder runs on a single CPU thread inside your browser tab, requiring more time to process every frame at higher resolutions.
Are my video clips uploaded to an external server?
No, all video decoding and WebP encoding happen entirely on your computer within your local browser sandbox.
