PDF Pro turns your iPhone into a scanner, a converter and a PDF editor — and keeps the work on your device. SCAN ANYTHING Point the camera at a page. PDF Pro finds the edges, straightens the paper, cleans it up and shoots when your hand settles. Multiple pages, one document, ready to send. CONVERT WITHOUT UPLOADING Photos, Word, Pages, PowerPoint, Keynote, Excel, Numbers, PNG, JPEG, HEIF and HEIC become PDFs on your phone. No upload, no waiting. EDIT THE DOCUMENT, NOT A COPY Add or delete pages, reorder them, rotate the whole file, fill in form fields, place your signature. Long documents open straight away and stay smooth while you scroll. PASSPORT PHOTOS, IN YOUR COUNTRY'S MEASUREMENTS Passport, ID card or driving licence: the app finds the face, measures the head and crops to the rules of the country you pick — 35 × 45 mm in Europe, square in the United States. It tells you what is wrong before you go and print, and lays out a 10 × 15 cm sheet with six copies. There is a tool that removes the background from a photo too. Both are included in the subscription. And if a photo is too heavy to send, you can make it smaller — many at once, and that one is free. FIND ANY DOCUMENT AGAIN Organize the archive with folders and tags, and search inside the text of your PDFs — not just their file names. Everything syncs across your devices through your own iCloud account. ASK YOUR DOCUMENT Get the short version of a long report, or the one answer you were looking for, without reading forty pages. A TOOLBOX, NOT A MENU Merge, split, compress with a preset that says what it costs, protect with a password, redact what should not be read, compare two versions, read a document aloud. ON IPAD AND ON MAC, TOO A layout made for the larger screen, and on the Mac a real window: sidebar, document list and page side by side, a File menu with keyboard shortcuts, and drag and drop. It is a Universal Purchase, so one subscription covers your iPhone, your iPad and your Mac. Plus a Home Screen widget and Shortcuts support, so scanning or converting can be one tap or one phrase to Siri. PRIVACY BY DEFAULT Scanning, conversion and editing happen on your device: your documents are not uploaded to do them. Two features do use a secure online service, and only when you ask for them — asking questions about a document, and the few conversions an iPhone cannot do on its own. Available in English, Dutch, French, German, Italian and Spanish. PDF PRO SUBSCRIPTION A subscription unlocks sharing, exporting and printing your documents, with no limit on how many. Weekly and yearly plans are available; the yearly plan starts with a free trial. There is also a 24-hour pass: a one-time purchase that does not renew. Payment is charged to your Apple Account at confirmation of purchase. The subscription renews automatically at the same price unless it is cancelled at least 24 hours before the end of the current period. Manage your subscription or turn off auto-renewal in your account settings after purchase. Any unused part of a free trial is forfeited when a subscription is purchased.

PDF Inbox

Your PDF library, only smarter. PDF Inbox gathers the PDFs on your iPhone — invoices, contracts, payslips, manuals, receipts — and organises them for you. No folders to create, nothing to rename. And it all happens on your device. No account, no cloud and no external AI. IT ORGANISES ITSELF Each document is read on your iPhone and filed under its category: invoices, contracts, bank, receipts, payslips, insurance, health, travel, official documents, taxes, manuals, studies, work, personal and other. If it gets one wrong, correct it once and it learns. The next invoice from that same company goes straight to the right place, and you can see exactly what it has learned and delete it whenever you like. IT READS WHAT'S INSIDE From every invoice it picks out the total, the date, the IBAN and who issued it. It also finds policy, contract and customer numbers, booking references and number plates, and links the documents that share them: the insurance policy with its receipt, the car inspection with the garage quote. And it suggests a name you can understand at a glance: 2026-09-18_Endesa_Invoice_61.15.pdf instead of IMG_20260918_0032.pdf. Scanned PDFs too: text recognition uses the system's own engine, without sending a single image anywhere. A SEARCH THAT UNDERSTANDS YOU Type it the way you would say it: "Amazon invoices from this year", "receipts over 100 euros", "insurance March 2025". PDF Inbox turns the phrase into filters — category, company, year, month, amount — and shows them as tags you can remove with one tap. It searches inside the documents, not just their names: type "tenant" and the lease shows up even if the file is called "doc3.pdf". It shrugs off accents, plurals and small typos, knows that "salary" means your payslips, and understands English, Spanish, French, German and Italian. And when nothing matches every word, it says so and shows the closest results instead of an empty screen. HOW YOUR DOCUMENTS GET IN · From the Files app, one or several at a time · A whole folder in one go · From any other app, with "Open in PDF Inbox" YOUR DOCUMENTS STAY HERE Your documents never leave your device. They are not uploaded anywhere, there is no account or sign-up, and no external AI ever sees them. You don't have to take our word for it: the app works just the same in airplane mode. What does go online has nothing to do with your documents. PDF Inbox is free and shows ads from Google AdMob, and iOS asks for your permission before they can use your device's advertising identifier. The app also checks for updates when it opens. Neither ever receives your files or anything inside them. It is all explained in the privacy policy. The original files are never modified or deleted: PDF Inbox always works on its own copy. ALSO · Fast PDF viewer with zoom and page counter · Favourites, plus filters by year and by company · Sort by relevance, date, size or name · Light and dark mode · In English and Spanish; reads documents in five languages · Works offline

Verdict
The clearest difference is in-app purchases: PDF Inbox at none against PDF Pro's 7. PDF Inbox also leads on iOS requirement (15.1 vs 26.0). PDF Pro's advantage is ads (none vs shown). On price and device support there is nothing between them.
