For example, your Word, Excel or PowerPoint files will be converted by Microsoft Office Word, Excel or PowerPoint software by default. If the "Always use open-source projects to convert documents" option is checked, your files will be converted by LibreOffice software instead of Microsoft Office. Check more information on conversion options.

The history file list is stored as "Local Storage" in your web browser only, it will not be exposed outside of your current web browser. You can remove history by clicking the "Delete all files" button which can be found in most pages.
A: Most conversion failures are caused by server overload. The allocated server's CPU or memory is currently 100% occupied so it doesn't have enough resources to complete your conversion. You can try it again a few minutes later if this happens. There are also many other reasons may cause conversion failure, for example: the source file is not supported, corrupted, encrypted with password or Digital Rights Management (DRM) etc. If your conversion is failed, you can click the "Failed!" button next to your file to check out the exact reason.
