Need to stamp "DRAFT", "CONFIDENTIAL" or your logo on a PDF before you send it? Seally adds a text or logo watermark to every page of a PDF, right on your iPhone.
Pick a PDF, type your text or choose a logo from Photos, adjust the look with a live preview, and tap Apply Watermark. Then share the new PDF or save it to Files.
• TEXT OR LOGO — type any text (for example "DRAFT" or "© Your Name") in white, black, indigo or red, or use an image from your photo library as a logo stamp.
• NINE POSITIONS — place the stamp in any corner, along an edge or dead center on every page.
• OPACITY, SIZE AND ROTATION — opacity from 10% to 100%, size from 10% to 50% of the page width, and a tilt from −90° to 90° for the classic diagonal look.
• KEEPS YOUR PDF INTACT — pages are redrawn as vectors, so text stays sharp and selectable, and links, annotations and bookmarks are carried over to the watermarked copy.
• WATERMARK MANY AT ONCE — with the unlock, select up to 50 PDFs in one go and stamp them all with the same settings.
• SHARE OR SAVE — export the watermarked PDF to Files, Mail or any app on the share sheet. Your original file is never changed.
Honest scope: Seally stamps the same watermark on every page; it does not edit page content, and password-protected PDFs need to be unlocked first. A watermark is a visible mark, not encryption or copy protection.
Everything happens on your iPhone — your PDFs are not uploaded and no account is needed.
Try it free — 3 watermarked PDFs. A one-time $4.99 purchase unlocks unlimited PDFs and multi-file watermarking. No subscription, no ads.

Fixed: on iOS 27, watermarked PDFs lost their bookmarks. The table of contents now comes through intact, nested entries included, and each opens the right page.
