Find out if your PDF was modified

No, our tool provides indicators and signals based on metadata and structure analysis. This is not forensic proof and should not be used as legal evidence.

The score summarizes observed metadata and structural indicators. It is not a calibrated probability of fraud, and a low score does not establish that a document is original or authentic.

Many normal workflows create editing signals: saving in different software, printing to PDF, form filling, etc. The tool detects patterns, not intent.

We remove Author, Title, Subject, Keywords, Creator, Producer, CreationDate, ModDate, and XMP metadata streams.

No. Metadata removal only removes invisible metadata. All text, images, and formatting remain exactly the same.

Yes. Any modification to a signed PDF invalidates its signature. This is by design - signatures are meant to detect changes.

Compression results vary. PDFs with large images typically see 30-70% reduction. Already optimized files may see minimal change.

Our compression optimizes images and removes redundant data. Text remains crisp. Image quality may slightly decrease for maximum compression.

Some PDFs are already optimized or contain mostly text. If compression cannot reduce size, we return your original file unchanged.

Files are temporarily stored for processing in private storage and on the processing server. During normal operation, document copies are automatically deleted within five minutes after processing finishes. Download needed results promptly; there is no long-term document storage.

Yes. All uploads and downloads use HTTPS/TLS encryption. Your files are protected during transit.

No. File processing is fully automated. No human ever accesses your documents.
