MetadataKit is a browser-based toolkit for viewing, editing and removing hidden metadata in digital files – camera settings, GPS coordinates, shutter count, author names, creation dates – across more than 500 file formats spanning photos, video, documents and audio. It processes everything client-side via WebAssembly, so files are never uploaded to a server, and it handles gigabyte-scale files with batch processing.
100% client-side processing is the feature that actually matters here: a metadata tool that strips GPS coordinates or author names for privacy reasons is only as trustworthy as its promise not to see that data itself, and running entirely in the browser removes the question rather than requiring you to take a privacy policy’s word for it. Supporting the standard metadata formats (Exif, IPTC, ID3, XMP) rather than just one file type also makes it a single tool for a job usually split across several format-specific utilities.
Client-side WebAssembly processing means very large batch jobs are bounded by your own device’s memory and CPU, not a server’s, which can be slower for genuinely huge batches even though it’s better for privacy. It’s also a utility, not an editor – it exposes and manages metadata, it doesn’t alter the actual image or audio content itself.
