Convert HEIC to WebP in your browser
HEIC is introduced by Apple in iOS 11 (2017) to halve the storage cost of iPhone photos, about 50% smaller than equivalent JPG at the same visual quality. Google's WebP is the more practical choice when supported by Chrome, Firefox, Edge, Safari 14+ and 95% of modern browsers. Filzy converts HEIC to WebP fully in your browser using libheif compiled to WebAssembly 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 HEIC 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 HEIC 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 HEIC files at once. Filzy converts them in parallel using your CPU cores and packages everything as a single ZIP archive.
