Formats and privacy
PDF input is validated by its file signature and parser. This tool runs in your browser. Document contents are not uploaded to MyDocverter or sent to a conversion service. Standard hosting access logs can still record page visits and IP addresses.
Frequently asked questions
Is this free?
Yes. No account, payment or subscription is needed.
Why was my file rejected?
Encrypted, malformed or oversized files may not be supported. The job limit is 50 MB and 300 PDF pages; rendering is limited to 100 pages to reduce browser memory use. These are resource safeguards.
Will the result preserve everything?
Overlays do not prevent copying. Text uses the Latin WinAnsi character set. Rewriting signed documents can invalidate their signatures. Check the final file before sharing.
