Convert JPG to WebP in your browser
JPG is standardised in 1992, still the universal lossy photo format on the web and in cameras, small to medium for photos, configurable via quality settings. Google's WebP is the more practical choice when supported by Chrome, Firefox, Edge, Safari 14+ and 95% of modern browsers. Filzy converts JPG to WebP fully in your browser using optimised JPEG encoder in Rust for decoding and libwebp compiled to WebAssembly for encoding. The original file never leaves your device, no upload, no tracking, no daily cap. You can drop a single file or batch dozens at once and download the result as a ZIP.
Files stay on your device
Your JPG files are decoded inside a Web Worker via WebAssembly. Nothing reaches a server, nothing is logged, no temporary copy is kept anywhere.
Quality preserved by default
Filzy decodes the JPG pixels, then re-encodes them with libwebp compiled to WebAssembly at high quality. EXIF metadata is preserved when the target format supports it.
Batch entire folders
Drop dozens of JPG files at once. Filzy converts them in parallel using your CPU cores and packages everything as a single ZIP archive.
