Drop files to scrub their metadata

Images, PDFs, Office docs, video, audio and vectors — up to 50 at once. Everything is analyzed and cleaned in your browser; nothing is uploaded.

Metadata & EXIF Privacy Scrubber

A zero-knowledge studio for finding and permanently removing hidden metadata from images, documents, video, audio and vector files — EXIF, GPS, XMP, IPTC, MakerNotes, ID3 tags, Office document properties, QuickTime atoms and more. Every byte is parsed and rewritten in your browser. Nothing is uploaded, no server is contacted, and — unlike most “GPS map” features — we never fetch map tiles, because doing so would leak the very coordinate you are trying to erase.

How it removes metadata (per format)

  • JPEG / PNG / WebP: the EXIF (TIFF) block is re-serialised keeping only the tags you allow, so you can drop GPS while keeping orientation; XMP, IPTC and comment segments are removed as chosen. The image pixels are untouched.
  • TIFF / HEIC / AVIF: these can’t be edited byte-safely, so the pixels are decoded and re-encoded to a clean PNG/JPEG — all metadata is dropped together and the format changes.
  • PDF: the Document Info dictionary and XMP stream are deleted with pdf-lib, which also collapses incremental-update history.
  • DOCX / XLSX / PPTX: the package is unzipped and docProps/core.xml, app.xml and custom properties are cleared, then re-zipped.
  • MP4 / MOV / M4A: the udta/meta tag boxes (including QuickTime GPS) are erased in place as zeroed free boxes, so sample offsets stay valid and playback is unaffected.
  • MKV / WebM: Title, dates, muxing/writing app and the Tags block are neutralised in place as EBML Void elements.
  • MP3 / WAV / FLAC: ID3v2 frames, RIFF INFO and Vorbis comments are rebuilt without the fields you remove; ID3v1 and embedded cover art are dropped.
  • SVG / EPS: executable <script> elements and on* handlers are stripped, along with editor namespaces, the <metadata>/RDF block and DSC author/date comments.

On honesty and limits

This tool edits container metadata; it does not run OCR, and it will not remove information that is part of the visible content (text under a black box, faces in a photo, tracked changes rendered into a document body). For ISO-BMFF (MP4/MOV) and Matroska, tags are cleared as a block rather than one field at a time, which the file card notes. The “Preserve file dates” toggle records your intent, but browsers set a downloaded file’s own timestamp to the moment it is saved — the embedded timestamps inside the file are what this tool actually controls.

FAQ

Are my files uploaded?
No. Parsing, tag detection, rewriting and ZIP packaging all run in your browser with Web APIs. No file, and no coordinate, ever leaves your device.
Why doesn't the GPS map show a real map?
Because loading a map tile would send the file's exact latitude and longitude to a tile server — leaking the location this tool exists to remove. We plot the point locally and offer an explicit link you can choose to open.
Can I keep some metadata and remove the rest?
Yes. Switch to Custom mode and toggle the categories — geolocation, device, identity, timestamps, thumbnails, scripts. The live diff shows exactly what will be stripped before you run it. (MP4/MOV and MKV clear tags as one block.)
Why did my HEIC/TIFF change format?
HEIC, AVIF and TIFF store metadata in structures that can't be rewritten safely in a browser, so we decode the pixels and re-encode to a clean JPEG or PNG. That guarantees zero residual metadata at the cost of the original container.
Does removing metadata change the image quality?
For JPEG, PNG, WebP, GIF and all the audio/video/document formats, no — only metadata bytes are touched and the media stream is copied verbatim. Only the re-encoded formats (HEIC/AVIF/TIFF) are recompressed.
How many files can I process at once?
Up to 50 per run. Files are processed a few at a time in the background to keep the interface responsive, and the batch exports as a single ZIP.
