When to keep the DOC
Keep the DOC as your editable copy, or better, convert it to DOCX if you still need to change the text.
Tips for the best result
- Standard fonts such as Arial and Times New Roman are matched closely.
- Very old documents may use fonts that are no longer common; they are replaced by similar ones.
- Images, tables and page numbers are kept.
Common problems and fixes
- Some characters look wrong.
- Very old DOC files sometimes use symbol fonts or old character sets. Open the file in Word, change the font of those characters, save and convert again.
- The file will not convert.
- Password-protected DOC files cannot be opened. Remove the password in Word first.
PDF – Portable Document Format
PDF is the standard format for documents that must look the same on every device. It preserves layout, fonts and images, but is difficult to edit.

Frequently asked questions
What is the difference between DOC and DOCX?
DOC is the older binary Word format; DOCX (Word 2007 and later) is based on XML, smaller and more robust. Both convert to PDF here.
Do I need Microsoft Word?
No. The conversion runs on our server with LibreOffice.
How do I convert DOC to PDF?
Click Select File or drop your DOC file onto the upload box. The converted PDF appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
