Local Metadata Stripper

Remove hidden GPS coordinates and tracking data from Images and PDFs.

100% Local - Maximum Privacy

Your files are parsed and scrubbed directly in your browser's memory. We do not upload your identifiable data to any backend, ensuring complete anonymity.

Why you must scrub metadata before sharing files

Every time you take a photo with your smartphone, hidden data called EXIF (Exchangeable Image File Format) is embedded directly into the image file. If you have location services turned on, this means the exact GPS coordinates (down to the meter) of where you took the photo are attached to it. When you share this photo online, you are broadcasting your location to the world.

Similarly, when you create or edit a PDF document using software like Microsoft Word or Adobe Acrobat, it automatically tags the document with hidden metadata. This often includes your full name, the company name, the software version used, and the exact dates of creation and modification. This can be devastating for whistleblowers, activists, or simply individuals who value their privacy when uploading documents to public platforms.

How Our Local Metadata Stripper Protects You

  • For Images (JPEG, PNG): We utilize raw pixel extraction. By drawing the image into a virtual HTML5 Canvas and exporting a pristine copy, all EXIF tags (including GPS location, camera serial numbers, and exposure times) are permanently annihilated.
  • For PDFs: We use an open-source WebAssembly engine (pdf-lib) to hook directly into the PDF document dictionary and actively wipe out the Author, Creator, Producer, Title, and Subject fields, resetting all timestamps to zero.

The Privacy Paradox: Many "free online metadata removers" ironically require you to upload your files to their servers to clean them. This defeats the purpose of privacy. Our tool operates strictly within your browser. If you don't trust us, turn off your Wi-Fi after the page loads—the tool will continue to strip your files flawlessly.
