How the File Metadata Viewer Works
AnyTool parses metadata entirely in the browser. Photos are read with exifr (EXIF, XMP, IPTC, ICC, GPS, JFIF, IHDR across JPEG/TIFF/HEIC/AVIF/PNG/WebP); audio and video use music-metadata (ID3/Vorbis/MP4 tags, container, codec, duration, bitrate); PDF Info/XMP and PNG text chunks have dedicated binary parsers; Office documents (DOCX/XLSX/PPTX) expose their docProps via JSZip. Every file also gets name/size/type and a SHA-256 hash. Heavy parsing runs in a Web Worker, results are grouped, GPS is mapped (link-out, no embedded tracker), and everything can be exported to JSON/CSV — or the file can be stripped of all metadata into a clean copy, all without an upload.
- Runs client-side — the file is never uploaded
- EXIF/XMP/IPTC/ICC/GPS for photos incl. HEIC, via exifr
- Audio/video tags + PDF + Office document properties
- GPS coordinates with OpenStreetMap / Google Maps links
- JSON & CSV export + SHA-256 hash
- Lossless metadata removal (JPEG/PNG) downloadable locally
