Scan anything on paper and turn it into a clean, professional PDF in seconds. Scan Studio is the scanner that lives in your pocket, ready whenever a receipt, contract, or handwritten note needs to become a proper document. Here is the problem with paper: it gets lost, it fades, and it is never with you when you need it. Scan Studio fixes that. Point your camera at a page and the app finds the edges, straightens the angle, removes shadows, and gives you a sharp scan that looks like it came from an office scanner. Keep snapping and a 20 page contract becomes one tidy PDF, ready to email before you have even left the room. WHY YOU WILL WANT IT ON YOUR HOME SCREEN SAVE TIME EVERY DAY Scanning takes seconds, not minutes. Capture page after page without stopping, so long documents are no longer a chore. Import photos or existing PDFs and work with everything in one place. It works just as well on iPad as on iPhone, so you can scan with whichever device is in your hand. LOOK PROFESSIONAL Smart filters powered by machine learning clean up your scans, sharpen the text, and remove artifacts, so the PDF you send to a client or a landlord looks polished. Set page sizes, reorder pages, and export exactly what you want. ONE APP FOR ALL YOUR PDF JOBS Stop juggling a different app for every little task. Merge several files into one, split a long PDF into parts, compress a heavy document so it actually sends, add a watermark, or lock sensitive files behind a password. From the moment you point your camera at a page to the moment the finished PDF lands in someone's inbox, everything happens in one place. KEEP EVERYTHING ORGANIZED AND PRIVATE Store your documents in folders in the built in library, so the receipt from last March takes seconds to find, not an afternoon. Back everything up privately with iCloud, using your own Apple account and no third party servers. Your documents stay yours, and only you can access them. WHAT PEOPLE SCAN WITH SCAN STUDIO Receipts and expenses for tax season. Contracts, agreements, invoices, and bills. ID cards and passports. Homework, lecture notes, and whole textbook chapters. Recipes, warranties, whiteboards after a meeting, and the kids' drawings you cannot bear to throw away. If it fits in front of your camera, it fits in Scan Studio. EVERYTHING INSIDE • Fast scanning with automatic edge detection, plus manual crop when you want full control • Automatic shadow and artifact removal for clean, readable pages • Color, grayscale, and black and white filters tuned for documents • Multi page scanning into a single PDF • Search inside your documents • Merge, split, and reorganize PDFs • Compress PDFs to save space and add watermarks • Password protect sensitive documents • Convert images to PDF, or PDF pages to images • Document library with folders to keep everything tidy • Private iCloud backup and sync across your iPhone and iPad • Export and share as PDF or JPG, print, or upload to your favorite cloud drive WHAT USERS SAY "By far the best scanner app I've come across!

Verdict

The call

The clearest difference is monetization model: Document Scanner at freemium against PDF Converter's subscription. Document Scanner also leads on review sentiment (90% vs 67%) and rating (4.7 vs 4.4). PDF Converter's advantage is ratings volume (6K vs 556) and device support (4 vs 2). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. PDF Converter sells 13 in-app purchases, starting at $4.99 per 7 days and Document Scanner sells 4 in-app purchases, starting at $2.99 per 7 days. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings
