WebP Editor & Converter
WebP is Google's modern image format that delivers both lossy and lossless compression with dramatically smaller file sizes than JPEG or PNG. FastEdit gives you full control over animated and static WebP files: trim frames, adjust quality, crop, and convert between formats, all processed locally in your browser through WebAssembly.
Whether you need to optimize a hero image for page speed or fine-tune an animated WebP sticker, FastEdit handles it without uploading a single byte to any server.
