DOC is the older binary Microsoft Word format from Word 97-2003. PDF is the universal fixed-layout format for sharing documents exactly as designed. FileConverter turns your DOC into PDF online in seconds - free, privacy-first, and with no software to install or account to create.

It opens in every browser, Adobe Acrobat, and built-in OS viewers.

Troubleshooting
- If the file exceeds the limit shown below, compress images, trim video, or split archives before retrying.

- Password-protected PDFs must be unlocked before conversion.
- Heavy formatting may shift slightly — allow a minute to tidy headings in Word or a similar app.
