Input, output, limits
Input is PNG/JPG from disk. Read/write runs in this browser via WASM. Local files are not uploaded to this site.
Safely edit EXIF metadata of image files with this client-side tool. Files are never uploaded to servers — all processing happens locally in your browser.
This page is the official demo. exiv2-wasm ports the C/C++ Exiv2 library to WebAssembly to enable EXIF/IPTC/XMP read/write in browsers, with robust Unicode (e.g., Korean) support.
