Scan paper into a clean PDF, then merge, split, compress, reorder, lock or unlock it. Seven tools, free, all running on your iPhone. Nothing is uploaded, ever. No account, no subscription, no ads. Your documents stay exactly where they already are. EVERYDAY JOBS Shrink a PDF until it fits an email limit. Lock a tax return before you share it. Pull the one page you need out of a long contract. Turn a school form on the kitchen table into a PDF you can send in a minute. Combine a stack of statements into a single file. SCAN Point the camera at a page, or pick photos from your library. Paradoc finds the edges, squares up the perspective and cleans up the page. An on-device neural model lifts shadows and uneven lighting, so a page shot under a desk lamp comes out clean and legible. Up to 20 pages per document. MERGE Combine up to 20 PDFs in the order you choose. Password-protected files are handled one by one, each with its own password. SPLIT Pull a page range out into its own PDF. If the source was encrypted, the result stays encrypted. COMPRESS Three presets: Light, Balanced and Maximum. Paradoc re-encodes images, subsets fonts and repacks object streams, the same techniques desktop tools use. Text stays text. Bookmarks, form values, annotations and document metadata stay intact. ORGANIZE Reorder, delete and rotate pages from a thumbnail grid. PDF TO IMAGE Export pages as JPEG images, from 75 to 600 DPI, up to 20 pages per export. PROTECT AND UNLOCK Lock a PDF with AES-256, the strongest encryption the PDF standard defines. Unlock removes a password you know, or clears owner-only restrictions on printing and copying. PRIVATE BY DESIGN Paradoc makes no network requests. None. There is no server, no sign-in, nothing quietly phoning home. Switch on airplane mode and every feature keeps working, on a plane, in a basement, anywhere. Your contract, your tax return, your medical letter: none of it needs to visit someone else's computer to be scanned, merged, shrunk or locked. The work happens where the file already is. BUILT FOR THE PDFs THAT USUALLY BREAK THINGS Password-protected files, including older RC4 and AES-128 ones, open and stay encrypted through Split, Organize and Compress. Files locked against printing or copying are detected and explained before you continue. Digitally signed PDFs are checked before anything is touched, and you are warned when an edit would invalidate a signature; certified documents are left alone. PDF/A archives are flagged before you change them. Merge two forms with the same field names and the result still works. Files up to 100 MB. A PDF comes out the way it went in. Text that was selectable stays selectable, and pages stay as sharp as they were at any zoom, because Paradoc works on the file itself instead of turning pages into pictures. Available in English, Spanish, Portuguese, Hindi, Chinese, Russian, Arabic and Hebrew, with full right-to-left layout.
