FAQ

Does pdf viewer upload my document?

No. Processing runs in your browser. The page does not send the selected PDF to a document-processing server.

Can this tool open a password-protected PDF?

No. Remove the password with the correct credentials before using this page. Encrypted files may fail during parsing.

Will the downloaded result preserve every advanced PDF feature?

Standard pages are supported, but complex XFA forms, unusual embedded objects, and vendor-specific metadata may not be preserved.

What should I do with a very large PDF?

Try a smaller file or split the document first. Browser memory limits vary by device, page count, and image resolution.

How can I verify the result?

Open the downloaded file in a separate PDF reader and inspect the relevant pages or properties before sharing it.
