Check what your photo file reveals
Every photo carries more than its pixels. Drop a JPEG, HEIC, PNG or WebP file and the check reads the file itself, in your browser, without uploading it.

What the instant check reads
- Camera tags: make, model, the maker note a phone writes, and whether a camera claim comes without one.
- Editor traces: the Software tag and XMP CreatorTool, which name the app that last saved the file.
- Location and time: GPS coordinates, time-zone offsets and DateTimeOriginal, and whether they agree.
- JPEG structure: quantization tables, Adobe/Photoshop markers, the embedded thumbnail and the colour profile.
- HEIC structure: the Exif item, Apple maker note, depth or Portrait images, and the HEVC image item.
- The file name, when it looks like an export rather than a camera original.
Two deeper scans, only if you ask
- Forensic read: sends the file to our server for a metadata, container and C2PA provenance read. It does not test sensor noise, compression history or invisible watermarks.
- Compare to original: upload the original too and see the PDQ perceptual-hash distance between the two pictures.
Files for the deeper scans are measured and discarded: nothing is stored. Up to 25 MB per file.
Questions, answered
Is my photo uploaded?
Not for the instant check: it reads the file in your browser. The forensic read and the compare send the file to our server only when you start them; it is measured and not stored.
Can it show where a photo was taken?
Yes, if the file still contains GPS tags. Many apps remove them when you share, so “No GPS” is common and is not an error.
What is C2PA?
C2PA (Content Credentials) is a signed record of how a file was made or edited, added by some cameras, phones and editing apps. The forensic read reports whether a manifest is present and whether its signature checks out.
What does the perceptual-hash comparison tell me?
How visually close two pictures are under Meta's PDQ hash, as a distance between the two files. It measures the files; it does not tell you how any platform will treat a post.
Does a clean result mean anything is guaranteed?
No. The check describes what is in the file's metadata and structure. It cannot see the image's content analysis or any platform's rules.
