Scan, edit, sign and convert PDFs right on your iPhone — no desktop, no signup, no watermarks on your work. RaptorPDF puts a full PDF workshop in your pocket, built around one idea: your documents are yours. SCAN PAPER INTO PDF Point your camera at a page and RaptorPDF finds the edges, straightens the perspective and cleans up the image — the way a real desk scanner would. Scan a whole stack in one go and every page lands as a single sharp PDF, ready to annotate, reorder or sign. Built-in OCR text recognition turns the scan into a searchable PDF, so you can find and select the words on the page instead of staring at a picture of them. Contracts, receipts, notes, ID pages, homework: paper goes in, a clean PDF comes out. A REAL PDF EDITOR, NOT A VIEWER Most mobile PDF apps are just a reader. RaptorPDF lets you work: • Add text anywhere on the page, in any size and color • Highlight passages and mark up what matters • Draw freehand, add shapes, boxes and circles • Drop sticky notes with adjustable opacity • Undo and redo every change, or tap any mark to edit or delete it • Redact content you need to hide PDF TO WORD — AND BACK Turn a PDF into a fully editable Word document (DOC, DOCX) with the layout, tables and formatting intact, then convert it straight back. Also converts to and from images (JPG, PNG) — so a photo becomes a PDF, and a PDF becomes shareable images. SIGN AND FILL, WITHOUT PRINTING Draw your signature, type it, or upload one you already have. Save it once and reuse it forever. Place it, drag it, resize it, done — no printer, no scanner, no back-and-forth. Fill in PDF forms and add your e-signature directly on your phone. ORGANIZE AND OPTIMIZE • Merge and combine several PDFs into one • Split a large PDF or extract the pages you need • Reorder, rotate or delete pages • Compress files that are too big to email • Resize pages and add page numbers • Add a watermark • Lock a PDF with a password, or remove one you own COMMON THINGS PEOPLE DO WITH RAPTORPDF • Sign a PDF on your iPhone without printing it • Convert a PDF to Word, edit it, and convert it back • Scan paper documents to PDF with your camera • Use OCR to make a scanned PDF searchable • Combine several PDF files into one • Compress a PDF that is too large to email • Fill out a PDF form on your phone PRIVACY FIRST — AND WE MEAN IT Almost every tool here runs entirely on your device. Your merges, splits, edits, signatures, annotations, scans and compressions never leave your iPhone. There is no account required to start, no upload queue, and nothing stored on a server waiting to be breached. (One exception, stated plainly: high-fidelity PDF to Word conversion is handled by a secure conversion service, because that quality is not achievable on-device. Everything else stays local.) BUILT FOR A PHONE, NOT SHRUNK ONTO ONE Big tap targets, a tool sheet you can reach with your thumb, and a canvas you can pinch and pan. Files open from Files, Mail, Photos, iCloud Drive or any share sheet, and go back out the same way. FREE AND PRO Free includes 3 PDF operations per day and files up to 50MB — enough for everyday paperwork, with every tool unlocked. No tool is hidden behind a paywall. Pro removes the daily limit and raises the file ceiling to 300MB: • Pro Monthly — $4.99 per month • Pro Yearly — $39.99 per year (works out to $3.33 a month) Prices are in USD and may vary by storefront. Subscriptions are charged to your Apple Account at confirmation of purchase and renew automatically unless canceled at least 24 hours before the end of the current period. Manage or cancel anytime in your Apple Account settings. Whether you are signing a lease on the train, scanning receipts at a kitchen table, or turning a PDF back into a Word file before a deadline — RaptorPDF has the tool, and it works in seconds.
