Convert WebP to PNG in your browser
WebP is released by Google in 2010 as a more efficient successor to JPG and PNG, around 30% smaller than JPG and 25% smaller than PNG at equivalent visual quality. Portable Network Graphics (PNG) is the more practical choice when universal across browsers, design tools, and any modern OS. Filzy converts WebP to PNG fully in your browser using libwebp compiled to WebAssembly for decoding and libimagequant + Rust 'image' crate 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 WebP 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 WebP pixels, then re-encodes them with libimagequant + Rust 'image' crate at high quality. EXIF metadata is preserved when the target format supports it.
Batch entire folders
Drop dozens of WebP files at once. Filzy converts them in parallel using your CPU cores and packages everything as a single ZIP archive.
