PDF Eye turns paper into real documents. Scan a page, and every word on it becomes text you can search, copy and even edit — right on the scan. SCAN IN SECONDS • The document camera finds the page edges, crops and flattens each page automatically. • Import photos or image files too. • Choose how pages are built: Text + Image keeps the look of the paper with real text; Text Only gives a clean page; Image Only keeps the picture with invisible, searchable text. EVERY WORD, RECOGNIZED • Text recognition runs on your device in many languages. Nothing is uploaded. • Search and copy the text of a page or the whole document. • Set your languages and their priority for the best results. EDIT SCANNED TEXT • Tap any recognized text to change the words, font, size, color and alignment. • Move, resize, align, distribute and merge text boxes. • Remove text and choose whether the scan underneath shows through. • Add new text anywhere on the page. SIGN & HIGHLIGHT • Sign contracts and highlight what matters with Apple Pencil or your finger. PAGES THE WAY YOU WANT • Reorder, crop, rotate, add or delete pages. • Paper size and orientation per page: automatic, A4, A3, A2 or US Letter. • Share the finished PDF anywhere.
