Leaf is a document scanner and a PDF editor in one app. Scan, edit and send documents right on your phone — no subscription and no ads. EDIT A DOCUMENT LIKE PAPER • Fix a date, an amount or a name on a scan — the new letters are taken from the document itself, so the edit looks native • Move a line somewhere else or erase it • Add a stamp and a signature at their real size. Take a photo of a stamp or sign with your finger — the background is removed automatically • Add text, a date, a check mark, a cross, a highlighter, an arrow or a box • Pinch to zoom the page — small text is edited precisely PDF WITHOUT QUALITY LOSS • Open PDFs you receive: text stays text and remains searchable, the file does not turn into a picture • Fill in forms — fields, check boxes and lists • Send with the values filled in, or keep the fields fillable for the recipient • Password-protect the file, forbid printing and copying A FILE OF THE RIGHT SIZE Choose where you are sending it — a government portal, email, a bank, a visa application — or set your own limit. The app picks the quality by itself and shows the final size before saving. If the file does not fit, it tells you how to make it lighter. LIKE A REAL SCANNER • Automatic page edge detection and batch scanning • Two-sided documents: scan the fronts, flip the stack, scan the backs — the pages are put in order automatically • Hand shadows, yellowed paper and uneven light are removed • Colour, grey and black-and-white looks — you see the difference on your own document REAL REDACTION What you cover is destroyed, not hidden under a black box: in the file you send there is neither image nor text left under the redaction. The app finds card, passport and phone numbers by itself and offers to cover them with a single tap. ORDER IN YOUR DOCUMENTS • Search the text of all documents, PDFs included • Sort by date, name or page count; list, grid or compact view • Folders, merging and splitting documents, page order • The title is picked up from the page heading • Import from Photos and Files, share and print YOUR DOCUMENTS STAY WITH YOU Documents are stored only on your phone: no sign-up and no cloud. Text recognition runs right on the device. Face ID lock. Free, with no ads and no limit on the number of documents. 11 languages, light and dark themes.
