PDFiles is a fast, private PDF scanner for iPhone. Scan documents, receipts, invoices, notes and forms into clean PDFs and save them directly to the Files app. What makes PDFiles different is the workflow. Choose a Files folder once, then every scan lands there automatically. No export maze, no repeated folder picking, no account and no cloud upload required. New in 2.0: faster batch scanning for real documents. Detect several documents in one camera image, choose the pages you want and set the final PDF order by the order you tap them. Scan multiple pages without an artificial 25-page limit. Keep the camera open, collect pages in a scan stack and save one multi-page PDF when you're done. Need to scan book pages, sheet music or two A4 pages side by side? Double Page Mode splits one photo into separate PDF pages. Move or delete the divider before saving. PDFiles also lets you fine-tune every scan. Adjust corners and edges, use the magnifier for precise placement or add a manual scan area when automatic detection misses something. Use PDFiles for: • documents • receipts • invoices • contracts • forms • notes • letters • sheet music • book pages Features: • Scan documents to PDF • Save PDFs directly to the Files app • Choose a default Files folder • Detect multiple documents in one photo • Create several PDF pages from one camera image • Scan longer documents without a 25-page limit • Keep scanning and save one multi-page PDF at the end • Split double-page scans into separate pages • Reorder pages before saving • Merge documents into one PDF • Compress PDFs to reduce file size • Adjust corners and edges manually • Add a manual scan area • Use A4, A3 and US Letter paper formats • Organize folders with colors • Switch target folders quickly Privacy first: Scans are processed locally on your iPhone with iOS and Apple frameworks.
