Frequently Asked Questions

Do you add watermarks to free outputs?

Never. Free outputs are identical to paid outputs. No watermarks, no ads injected into PDFs, no quality reduction.

What if my browser crashes during editing?

Since processing is local, a crash only affects the current session. Your original file remains untouched on your hard drive. Simply reopen the tool and re-upload.
