.doc is the old format from the Word 97-2003 era. The older a document is, the more easily its formatting breaks depending on the program that opens it, but fixing it as a PDF keeps it safe to store and share. Here you can convert an old .doc right away, with no need to re-save it in a newer format.

The moatool converter never uploads your document. A real office engine runs inside your browser to build the PDF, so even sensitive files stay on your device and there is no size limit.

Frequently asked questions

Do old .doc files open too?

Yes. It reads the Word 97-2003 format directly and turns it into a PDF. Unless the file is corrupted, you do not need to re-save it in a newer Word first.

Is there a file size limit?

No. Because nothing is uploaded to a server there is no upload cap; the only limit is your device memory.

Why is the first run slow?

The office engine is downloaded once the first time. After that it starts right away — you are downloading the engine, not sending your document.

Does my file go to a server?

No. A real office engine runs inside your browser to make the PDF, so contracts and HR files stay on your device.
