Frequently asked questions
Does a watermark prevent copying?
No. A watermark labels a document but is not encryption, access control or proof of ownership.
Is my content sent to a server?
No. Processing runs inside your browser. Optional editor recovery saves a draft on this device only. Read the privacy policy.
Will my original file be changed?
No. Downloaded results are separate copies. Open the finished output before sharing it or deleting an original.
