HexaConverter does not write its own encoders. Conversion is performed by established open-source projects, which is why the output is the same as what those tools produce anywhere else — no watermark, no re-encoding to a lower quality, and no format withheld to sell you something.

Getting the source
Each project is used unmodified and runs as a separate program, so the corresponding source is the upstream release linked above. If you would rather receive it from us, email info@hexaconverter.com and we will send the source for the version in use, at no charge beyond the cost of sending it.
Nothing on this page grants you rights over HexaConverter itself, and nothing about HexaConverter limits the rights those licences give you over the components named here.
Trademarks
Format and product names — among them Microsoft Word, Excel and PowerPoint, and Apple Pages — are trademarks of their respective owners. They appear here only to describe which file formats can be converted, which is the accurate way to say it. HexaConverter is not affiliated with, endorsed by or sponsored by any of them.
Our own material
The HexaConverter name, logo and the text of this site are ours. The files you convert remain entirely yours; see the terms of service, which claim no rights over your content beyond performing the conversion you asked for.
