您的檔案將保持私密

常見問題
No — this tool works without creating an account. There is no sign-up option at all right now.
新增浮水印 accepts PDF files and produces a PDF result, up to 1 file per job.
Only the specific change you make is applied — everything else on the page stays exactly as it was in your original file.
Your file is processed in an isolated job and deleted automatically, along with the result, once your download window ends.
