Questions answered
We explain meaningful limitations before conversion so you can decide whether this tool is appropriate for your document.
Are my PDFs uploaded?
No. This tool runs locally in a browser worker and does not send the files to our server.
Will digital signatures remain valid?
No. Combining a signed PDF changes the document and normally invalidates its signatures.
