Check the metadata of a PDF or an image
Which software produced this file, when was it modified, how many saved versions does it keep? Drop it here: it is read in your browser, with no sign-up, and the file is never sent.
Your file stays in your browser: it is not sent anywhere.
What the tool shows
A file keeps information about its own history, which you do not see when looking at the document on screen. The tool reads the standard properties:
- For a PDF: title, author, creating software, PDF producer, creation and modification dates, number of saved versions, presence of an electronic signature.
- For an image (PNG, JPEG, TIFF): software, camera, dates, and a C2PA provenance marker if there is one.
How to read the results
Does the software match the issuer?
A bill from a major supplier or a payslip usually comes out of business software. An image editor or a PDF editor is worth a question, but it is not proof: a document can legitimately be converted or compressed.
Are the dates consistent?
Compare the file’s dates with the date printed on the document and what you know of the case. A modification long after creation only makes sense if someone had a reason to change it.
How many versions?
Several successive saves can come from a filled-in form or a signature. For a document meant to come straight from its issuer, that raises a question. Our guide explains how to tell if a PDF was edited.
What if everything is empty?
Some tools write no properties, and messaging apps or screenshots often remove them. The absence of information proves nothing: ask for the original file.
In doubt about a document?
Analyze it for free: Docusan flags the anomalies and locates them on the document.
The limits of this tool
These properties can be missing or altered: they help you ask the right questions, but they prove neither that a document is genuine nor that it was forged. An edit may also leave no trace in the properties.
That is why the tool gives no verdict. To check a document, combine these properties with a check of the issuer and of the content’s consistency: our guide explains how to verify a document’s authenticity.
Going further with Docusan
Docusan also analyzes the document’s content, its pixels and its structure, then gives a verdict: No detection, Warning or Alert. The anomalies are located on the document, with a comment explaining them, and the decision stays with your teams. Unlike this tool, Docusan analyzes the file on its servers, hosted in the European Union (security and privacy).
FAQ
Your questions
Is my file sent anywhere?
No. It is read entirely in your browser: the file does not leave your computer, and this page keeps nothing.
Does the tool say whether a PDF is fake?
No. It shows facts about the file without concluding: these properties can be missing or altered, and an edited document is not necessarily fraudulent.
What is PDF metadata?
It is information stored in the file itself: title, author, software used, creation and modification dates. It does not show on the document’s pages.
Do I need an account?
No, the tool is free and needs no sign-up. Only Docusan’s full analysis requires an account, created from your work email.
