Your phone already contains a genuinely good document scanner - no app purchase needed. The difference between a crisp 'scan' and a grey photo of a page is technique, and the technique is three rules.

Open Notes -> new note -> camera icon -> 'Scan Documents'. Hold the phone over the page: it detects the edges, snaps automatically when steady, straightens the perspective, and keeps asking for the next page - so a 10-page contract becomes one multi-page PDF in under two minutes. Tap Save, then share as PDF from the note.
The same scanner lives in the Files app (long-press in any folder -> Scan Documents) if you want the PDF filed directly rather than in a note. After capture you can adjust corners by hand, switch color/grayscale/black-and-white, and re-shoot any single page - fix the worst page rather than rescanning the stack.
Open Google Drive -> the + button -> Scan (or the camera-with-document icon). Same flow: auto edge detection, perspective correction, auto-enhance, add pages, save as PDF straight into Drive. Recent Android versions surface the same scanner in the Files by Google app, and Samsung phones offer scan capture natively in the camera when a document is detected.
If the goal is the text rather than the document - copying a paragraph, grabbing a table - Google Lens (in the camera or as its own app) extracts editable text from the camera view directly, including handwriting more often than you'd expect. Scan for documents you keep; Lens for text you need right now.
Light from the side, not above: overhead light plus a hovering phone equals your own shadow across the page. Set the page near a window or lamp so light rakes across it, and kill the flash - flash on glossy paper creates a white blowout right in the middle of the text.
Contrast behind the page: a white page on a dark table lets edge detection lock on instantly; white-on-white makes it guess. And hold parallel: directly above the page, phone flat, then let auto-capture take the shot - it fires when the geometry is right, and resisting the urge to jab the shutter is half the quality. The black-and-white/'document' filter afterward is what turns a photo into a scan: it flattens the paper grey to white and blackens the text.
Scan all pages in one session so they land in one PDF - separate single-page PDFs are the classic rookie output that someone then has to merge. Both scanners let you reorder and delete pages before saving. For double-sided originals, scan front-back-front-back as you flip through; it keeps the order right without sorting later.
Name files like future-you searches: '2026-03 boiler invoice' beats 'Scan 47'. Save into one cloud folder per year (Drive, iCloud, or wherever your documents live) - the scan that exists only in a notes app or the camera roll is the scan you'll never find. Both platforms OCR scans automatically these days, so well-named PDFs become full-text searchable in Drive and Files.
For IDs, contracts, and anything with personal data: prefer the built-in scanners over free third-party scanner apps (several monetize by processing documents on their servers), send via the channel the recipient specified rather than ad-hoc chat, and delete strays from the camera roll and 'recently deleted' after sharing. If a scan must travel by email, a password-protected PDF (both platforms can export one) is cheap caution.
Know the ceiling, too: phone scans are excellent for contracts, receipts, forms, and records - genuinely flatbed-grade for text. The exceptions are photographs (use a photo-digitizing app or a real scanner for prints you care about) and anything a body explicitly requires as an 'original certified copy'. For the other 99% of paper, the phone is the scanner now.
No - iPhone Notes/Files and Google Drive scan, straighten, enhance, and produce multi-page searchable PDFs for free. Paid apps add niceties like batch OCR export or integrations, but the built-ins cover essentially all personal and small-office needs.
Scan with Drive, open the PDF in Google Docs (it OCRs on open), or use Lens/Live Text to copy the text out and paste it. Expect to fix formatting - OCR nails the words, not the layout.
Blurry: the phone moved - let auto-capture fire instead of tapping, and brace your elbows. Grey: ambient shadow plus the color filter - re-light from the side and switch the scan to black-and-white/document mode, which whitens the paper and sharpens text.
Use the document scanner, not the camera: pages added in one scanning session save as a single multi-page PDF. If you already have photos, both iOS (select -> Print -> share as PDF) and Drive can convert and merge them, but scanning properly the first time is faster.
