Metadata leak checker
Drop images or PDFs and see exactly what hidden metadata would leak if you shared them — GPS, names, device IDs, internal paths, even an embedded thumbnail of the original. Everything runs in your browser; nothing is uploaded.
What this checks
It reads the metadata embedded in your file — EXIF, XMP, IPTC, C2PA and PDF document info — and flags the fields that would expose you if the file were published: GPS coordinates, author and creator names, device serial numbers, software versions, timestamps, internal file paths, email addresses and the embedded EXIF thumbnail (which can still show pre-crop content). There's no database and no guessing: the evidence is inside your file and the check is exact. It reads images (JPG, PNG, WebP) and PDFs today; it doesn't yet open Office documents or video.
Frequently asked
How do you know what's a leak without a database?
We don't need one — the metadata is inside the file. We read it and match each field against a fixed set of rules for what's sensitive to publish (GPS, names, paths…). It's a linter for your file's metadata, not a lookup against outside data, so it's exact and private.
What's the embedded thumbnail warning?
Many photos carry a small preview generated from the original frame. Apps that crop, rotate or redact often don't update it — so the thumbnail can still show the original, uncropped or unredacted image. We extract and show it so you can see what's leaking.
Is my file uploaded?
No. The whole audit runs in your browser — the file never leaves your device. You can turn off your connection and it still works. To remove what it finds, use our metadata cleaner (also on-device).
