Free tier

Converts between around 200 file formats, including the awkward ones.
The converter that handles the pairs other sites quietly skip — CAD to PDF, EPS to SVG, DOCX to EPUB — and then lets you set the codec, resolution or DPI instead of accepting whatever default it fancies. Files are uploaded, converted on their servers and deleted afterwards, and there is a proper API if the job turns out to be a recurring one. It is the right first stop for an unfamiliar extension and the wrong one for a folder of confidential contracts.
Questions
A genuinely usable free tier with paid plans for volume or team features. Free use is metered as a daily allowance of conversion minutes, and video burns through it fastest.
Yes. CloudConvert sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
