Need to black out an account number, address or signature in a PDF before you share it? Redactly lets you draw redaction boxes and exports a new PDF where that content is actually removed โ not just covered up. Open a PDF, drag to draw black boxes over anything private, page by page, and tap Apply Redaction. Then share the redacted copy or save it to Files. โข TRUE REMOVAL โ every page with a redaction box is flattened into an image with solid black over your boxes, so the hidden text can't be selected, copied, searched or uncovered by deleting a shape. โข DRAW WITH A FINGER โ drag to draw a box over text, numbers, photos or signatures; touch and hold a box to remove it, or clear a whole page and start again. โข ALL YOUR PAGES โ move between pages with the page strip and redact as many pages as you need, up to 300 pages per PDF. โข OTHER PAGES STAY SHARP โ pages without boxes are copied as they are, so their text stays crisp and selectable, and their links and bookmarks are kept. โข NO HIDDEN LEFTOVERS โ comments and form annotations are not copied back onto redacted pages โ a redacted page carries only what you see on it. โข SHARE OR SAVE โ send the redacted PDF by Mail or Messages, or save it to Files. Your original file isn't changed. Honest scope: you choose what to redact โ Redactly doesn't search for or detect sensitive text automatically, so check every page. Redacted pages become images, so their remaining text is no longer selectable. Password-protected PDFs need to be unlocked first. Everything happens on your iPhone. Your documents are not uploaded and no account is needed. Redacting and previewing are free: check every redacted page before you pay. A one-time $4.99 purchase unlocks saving and sharing the redacted PDF. No subscription, no ads. Questions: overlapmarr@gmail.com
PDF Offline Studio

Every PDF tool you need. None of your documents ever leave your device. Most free PDF apps quietly upload your files to a server to do the work. This one doesn't, because it can't. The app is built with no internet permission at all. Your contracts, IDs, medical records and tax forms are handled entirely on your phone or Mac. It doesn't keep them either. There's no library and no cloud folder: you open a file, work on it, and save the result wherever you like. Nothing is left behind. PAGES - Merge several PDFs into one - Split a PDF: see exactly where it will divide before you commit - Extract only the pages you want - Delete, rotate and reorder pages by dragging MARK UP - Draw, highlight and add text anywhere on the page - Sign with your finger or mouse - Fill in PDF forms: type into fields, tick boxes, pick from lists - Stamp a page: Draft, Confidential, Approved and eleven more, or make your own - Watermark every page, once or tiled - Add page numbers SECURITY - Redact: removes what's underneath instead of covering it - Flatten PDF: fixes your marks and filled-in forms into the page so nobody can change them - Lock a PDF with a password, or remove one you know READ & TRANSLATE - Translate a whole PDF into another language, laid out where the original text was, or read the translation as clean text with Easy to read - Make searchable: find and copy the text in scanned pages CONVERT - PDF to images, images to PDF: photos go in without their location or camera details - Scan paper documents with the camera, straightened and cropped (iPhone and iPad) - Compress, with an honest warning when there's nothing to gain Redaction is the one worth explaining. Drawing a black box over a name doesn't remove it: anyone can still select the text underneath, and people have lost jobs over exactly that. Redact rebuilds the pages so what you covered is genuinely not in the file, then checks its own work and refuses to hand you the result if any readable text survived. Translation and text recognition use Apple's own frameworks, on your device, like everything else here. Translating needs iOS 18 or macOS 15 or later and the two languages downloaded once by your system; after that it works with no connection at all. It translates into languages written in Latin, Greek or Cyrillic letters. BUILT FOR PRIVACY, NOT MARKETED AS IT - No internet permission: verifiable, not just a promise - No library, no cache, no account, no sign-up - No ads, no analytics, no tracking, no crash reporting - Photos you turn into a PDF lose their location, time and camera details - Works on a plane, in a tunnel, anywhere Free. No subscription, no unlock, no Pro tier. Available in English, Spanish, Portuguese, German, French and Italian.

Verdict
The clearest difference is in-app purchases: PDF Offline Studio at none against Redactly's 1. PDF Offline Studio also leads on device support (4 vs 1). Redactly's advantage is update cadence (every 4 days vs every 2 weeks). On price, ads and iOS requirement there is nothing between them.
