What to check

Privacy: Server-side source files are deleted immediately after a successful conversion. If conversion fails, the source file is retained for up to one hour for error diagnosis and then deleted automatically.

  1. 1 Compare the result with the original before deleting or sharing anything.
  2. 2 Check content, layout, timing, fonts, or folder structure that matters to your workflow.
  3. 3 Keep the source file as a backup because some format-specific features cannot transfer.
