Paper in. Searchable PDF out. Foldline is a PDF editor and scanner for iPhone and iPad. Scan paper into PDFs, change the text on a page, fill in and sign forms, mark up pages, and merge, split, compress, redact or convert files. Everything happens on your device: no account, no uploads, no internet connection needed. FREE, AND PRO FOR LIFE • Free: scan to PDF, images to PDF, fill and sign forms, highlight and mark up, reorder and rotate pages, and search and share your PDFs. • Foldline Pro, a one-time purchase, unlocks the rest: editing a page’s text, text recognition (OCR), merge, split and extract, compression, redaction, password protection, watermarks, and PDF to images or text. • Try every Pro tool except Merge on one PDF for free before you buy. • No subscription: buy once, use it on all your devices with your Apple Account. SCAN PAPER TO PDF • Scan receipts, letters, contracts and forms. The camera finds each page’s edges and straightens it. • Capture many pages into one PDF, then crop, rotate, reorder or retake any of them. EDIT THE TEXT ON THE PAGE (PRO) • Double-tap a paragraph or a table cell and type. Fix a date, a name or a price in seconds. • Choose the font, size, bold, italic, underline, alignment and color. • The old words are removed from the page, not hidden, so they can’t be found or copied later. • On a scanned page the words are part of the picture, so they’re covered with the page’s color instead. FIND ANY WORD, EVEN IN SCANS (PRO) • Text recognition (OCR) makes scanned pages searchable, here and in other apps, so you can find, select and copy their words. • Reads English, Spanish, French, German, Italian, Portuguese, Chinese, Japanese, Korean and more. FILL & SIGN • Type into PDF form fields, check boxes and choose options. • On scanned or flat forms, add text and check marks wherever you need them. • Draw your signature once and reuse it, with the date beside it if you like. HIGHLIGHT & MARK UP • Highlight, underline and strike through text. • Draw with a pen or marker, and erase strokes you don’t want. • Add text, sticky notes, links, and shapes such as arrows, stars and check marks. • Your original stays untouched until you tap Save. ORGANIZE PAGES • Reorder, rotate, duplicate and delete pages in a thumbnail grid. • Pro: merge PDFs into one, in the order you choose. • Pro: split a PDF by page ranges, or extract chosen pages into a new file. COMPRESS & CONVERT • Pro: compress a PDF so it’s easy to email or upload. Only photos and scans shrink; text, links and form fields stay as they are. • Images to PDF: combine JPEG, PNG and HEIC images into one document. • Pro: PDF to images, as PNG or JPEG at screen, standard or high resolution. • Pro: PDF to text, as a .txt file. Scanned pages are recognized first. REDACT & PROTECT (PRO) • Redact names, account numbers and signatures: find every match, select text, draw a box or mark a whole page. • What’s under the boxes is removed from the new PDF, not just covered, so it can’t be searched, copied or uncovered. • Password-protect a PDF, and limit printing, copying and changes. • Stamp a text or image watermark, such as CONFIDENTIAL or your logo, on the pages you choose. PRIVATE BY DESIGN • Your documents stay on your device. Nothing is uploaded, not even for text recognition. • No account, no ads, no tracking, no subscription. • A file leaves the app only when you share or export it. THE DETAILS • Open PDFs from Mail, Files and other apps with the Share button. • If the app closes mid-edit, your unsaved changes are kept. • Supports Dark Mode and larger text sizes. GOOD TO KNOW • Your signature is a handwritten mark on the page, not a certificate-based digital signature. • Edited text is set in one of six common fonts, matched as closely as possible to the original. • If a drawing runs under a redaction box, that page is saved as a picture of the page, without selectable text.
