PDF Scanner turns your iPhone into a fast document scanner for everyday paperwork. Use it to scan receipts, IDs, invoices, contracts, forms, notes, assignments and office documents, then save them as clean, shareable PDF files. Open the camera, align the page and let automatic edge detection capture the document. Crop, rotate, apply filters, adjust brightness and contrast, and create readable scans that look organised instead of like quick photos. Add more pages, reorder them and build one multipage PDF from paper documents. Already have a document on your phone? Import photos, image files or existing PDFs, clean them up, arrange pages and save a new PDF. It is practical for students digitising notes, freelancers sending forms, small business owners saving invoices, and anyone who needs a scanner app without a desktop scanner. OCR text recognition helps you extract text from scanned pages and photos. Copy recognised text, share it as TXT or create selectable PDFs for notes, receipts, business paperwork and study material. When you need information from paper without typing it again, OCR keeps the workflow fast. For documents that need approval, add a handwritten signature directly on the page. Sign forms, agreements, letters and confirmations, then share the finished PDF by email, messaging apps or your preferred file destination. Useful workflows include receipt scanning, invoice capture, ID and card scanning, form scanning, photo to PDF conversion, image to PDF cleanup, note scanning, contract archiving, OCR text extraction and PDF merging. The app focuses on the jobs people search for most: PDF scanner, document scanner, scan to PDF, OCR scanner, receipt scanner, ID scanner, photo to PDF converter, PDF maker and signature tool. PDF Scanner keeps the experience simple: local document library, clear previews, page reorder, page merge, crop, rotate, filters, text recognition and signature tools. It is not a cloud team workspace or a complicated desktop PDF editor. It is a practical mobile scanner for the paperwork you need to capture, edit, sign and send today. Download PDF Scanner and make every document digital in seconds. For cleaner results, scan in good light and keep the phone as parallel to the paper as possible. After capture, adjust the page edges, remove extra margins, rotate pages and improve contrast so the text stays readable when you share, print or archive the file. That control matters whether you are scanning a small receipt, an ID card, a handwritten note or a multipage contract. The app is built around real mobile workflows: send back a signed form, keep expense receipts, turn class notes into PDF, reorder pages before emailing a document, extract one paragraph with OCR, or merge saved scans into a single file. The metadata and description naturally cover high-intent searches such as PDF scanner, document scanner, scanner app, scan to PDF, OCR reader, receipt scanner, ID scanner, photo to PDF, image to PDF, PDF maker, e-signature and document scan without claiming unsupported desktop editor features.
