No. Your PDF is processed in memory and immediately discarded. Only the extracted metadata is temporarily stored for your session.

Can PDF metadata be faked or modified?

Yes, PDF metadata can be modified. The metadata we show is what's embedded in the file, but it should be treated as informational rather than proof of authenticity.

Why does my PDF show no creation date?

Not all PDFs include creation date metadata. This depends on the software used to create the PDF and its settings.

We accept PDF files up to 100MB in size.
