Look at details saved in a PDF
PDF file checker
Check the software name, dates and update markers saved in a PDF. This runs in your browser without uploading the file. It cannot prove whether a particular word, number or signature was changed.
Drag and drop a PDF to check its file details
Looks at the PDF version, creator details, timestamps, and revision markers in this browser. These clues are not proof of authorship or fraud. Supports PDF 1.0 to 2.0 up to 30 MB.
What the checker reads
Four kinds of file details
These details describe the PDF file. They do not verify the document's contents or the identity of its author.
PDF header
Checks whether the file starts with a recognizable PDF header and shows its declared version.
Saved software names
Shows the creator and producer names written in the PDF, when present. Those names can be changed.
Saved dates
Shows creation and modification dates written in the file. Missing or different dates do not prove tampering.
Extra update sections
Counts markers that can indicate later saves. It does not show which words or images changed.
How to use this result
Compare the file details with what the sender told you. If an invoice, contract or other important document raises questions, ask its source to confirm it. A familiar software name or a single update marker cannot establish whether a document is genuine.
Frequently Asked Questions
Can this check prove that a PDF is genuine?
No. It shows details saved in the file, such as the software name, dates and signs of later updates. Those details can be changed or removed. Confirm important documents with their sender or another trusted source.
Why might a PDF have no creation date or software name?
A scanner, website or export tool may leave those details out or remove them. Missing details do not mean the document is fake.
What does an added update section mean?
Some PDF tools save later changes as extra sections. That may happen for a signature, a comment, an edit or another export step. This check cannot tell which content changed.
Can this check tell whether PDF text or images were made with AI?
No. The file details shown here do not identify how the text or images were created. If you need to check a picture in a PDF, review that selected image separately and keep the result limited to it.
