About MetaRase
MetaRase is a privacy-first tool for inspecting, cleaning, and verifying supported metadata in image files. This page explains how it works, how it is tested, and where its limits are.
What MetaRase does
MetaRase reads the container of a JPEG, PNG, WebP, GIF, AVIF, or HEIC image and reports the supported indicators it finds, such as EXIF, GPS, XMP, IPTC, comments, ICC profiles, embedded thumbnails, and C2PA / Content Credentials.
Cleaning rebuilds the image from its decoded pixels and exports a fresh file in the browser, then scans the result again so you can compare before and after.
Local by design
Scanning, cleaning, and verification run entirely in your browser. Image bytes, previews, cleaned output, and scan reports are never uploaded to MetaRase servers. Account, billing, and security data are handled separately, as described in the privacy policy.
How it is tested
The scanner is checked against the known metadata structures of each supported format and against sample files with real embedded indicators. The cleaner is verified by rebuilding a file and confirming that the supported indicators no longer appear in the output scan.
Reports describe categories and confidence rather than dumping raw values, so they show what a platform could read without exposing your coordinates or manifest contents.
What MetaRase does not claim
It does not remove pixel-level watermarks such as SynthID, steganography, perceptual fingerprints, or content visible in the picture. It does not guarantee how a third-party platform will classify an image, and it cannot validate every C2PA manifest cryptographically. Being precise about limits is part of the product.
Independent and transparent
MetaRase is an independent project. The source is available on GitHub, and the tool pages and guides explain the same behaviour you get in the cleaner. The guides are written to be honest about what works and what does not.
