Will my formatting stay the same?

Text, images, tables and page breaks are kept. Fonts that aren't embedded in your document may be replaced with a close match.

No. Uploads and converted files are removed after processing, and file contents are never used to train AI.

Can I convert several files at once?

Yes. Add up to 20 files, 25 MB each. You can download separate files as a ZIP or combine them into one document.
