.PDFi

Edit, sign, and annotate PDFs

$0.99

Markup, signatures, page editing, and export all in one app that runs exclusively on your device- with no account, registration, or internet required! A complete PDF editor that runs entirely on your device. Open a document, mark it up, sign it, reorganize the pages, and export a clean copy. Nothing is uploaded, no account is required, and every feature works offline. VIEW AND NAVIGATE Continuous scrolling with zoom in, zoom out, and fit to page. A sidebar gives you page thumbnails, the document outline, and full text search. Password protected files open with a simple unlock prompt. ANNOTATE AND DRAW Pen and highlighter for freehand ink, plus an eraser. Draw rectangles, ellipses, lines, and arrows. Select text to highlight, underline, or strike it through. Drop in text boxes with your choice of font size and color, or leave a sticky note. Any annotation can be selected afterward to move it, resize it from the corner handles, restyle it, or delete it. Full undo and redo covers every operation. SIGN Build a library of signatures and initials by drawing with your finger or trackpad, or by typing your name in a script font. Signatures persist across documents and across your iPhone, iPad, and Mac. They are placed as vector ink, so they survive saving and open correctly in other PDF viewers. EDIT THE PAGE ITSELF Whiteout covers content so you can type over it. Insert images directly into the page. Rotate, reorder, delete, and extract pages, insert a blank page, or merge in another PDF. Add a watermark across every page. PDFs with existing AcroForm fields can be filled in natively. CONVERT TO PDF Turn Word documents, RTF, RTFD, plain text, and HTML files into paginated PDFs, then edit the result right away. Word conversion is available on Mac. EXPORT AND SHARE Save in place, or Save As to pick a new name and location. Closing an edited document offers to save a copy so your original stays untouched. Share, print, export a flattened copy with annotations baked in, export an encrypted copy protected by a password, or pull a single page out as its own PDF. BUILT FOR EVERY DEVICE One purchase covers iPhone, iPad, and Mac. The Mac version uses a real Mac interface with menu commands and keyboard shortcuts, not a stretched phone app. PRIVACY There is no account, no analytics, and no network access. Documents you open never leave your device. Note: text that is part of the original PDF content cannot be reflowed or retyped in place. The built in workaround is whiteout plus a text box, then export flattened.
