Scan documents, IDs, receipts, and passports on iPhone & iOS. On-device OCR in 50+ languages, e-signature, merge, split, and searchable PDFs. No account required for scanning — documents stay on your phone.
The phrase "free PDF scanner for iPhone" is used loosely across the App Store, and it usually hides trade-offs: a 3-day trial that charges after, a "lite" edition with unusable output, daily scan limits, watermarks on exports, or an account required just to save a PDF. Before installing anything, it is worth knowing exactly what a scanner app gives you for $0.
This page answers that directly for ScanLens — what is in the free tier, what is locked behind Premium, and what costs nothing. If you are looking at product comparisons instead (which scanner app is best, feature by feature), see the PDF scanner app overview or the best scanner apps for iPhone in 2026. This page is about pricing and what "free" covers.
Short version: ScanLens is free to download, free to open, and free to scan on iPhone or iPad without creating an account. Free-tier exports include a watermark. Premium removes it and unlocks OCR, cloud sync, e-signatures, PDF tools, and searchable PDF export. The paid tiers are $4.99/week, $9.99/month, $29.99/year, or $59.99 one-time Lifetime license.
ScanLens does not hide the paywall in "premium pop-ups" in the middle of your scan. Every feature below is either labeled free or labeled premium from the moment you open the app. This is the precise list as of April 2026.

Not all "free" iPhone PDF scanners mean the same thing. Here is how the main options handle the free tier as of 2026:
It is worth walking through what scanning actually looks like when you never pay and never sign in, because "free" is easy to claim and harder to pin down. Here is the honest version of the no-cost path on ScanLens.
You open the app — no sign-up screen, no email gate, straight to the camera. Point it at a document and live edge detection finds the page borders; auto-capture takes the shot when the frame is steady. Add more pages and they stack into one multi-page document. Crop, rotate, fix perspective, and apply a filter (Original, Rich Color, Smart B&W, or Grayscale) to clean up the result. On-device OCR can read the text so you can copy it or check it on screen. None of that costs anything, and none of it requires an account.
When you export, the free tier produces a PDF, JPG, or PNG with a small ScanLens watermark on it, which you can then share through the iOS share sheet, print, or save to Files or Photos. For a lot of personal uses — a receipt you want to keep, a form you are storing for yourself, a page you are emailing to someone who does not care about a small mark — the watermark is a non-issue. Where it matters is professional output: a contract going to a client, a document you are submitting officially, anything where a vendor mark looks unprofessional. That is the line Premium is built to cross.
We are deliberate about this framing because an earlier version of this page was not clear enough about the watermark, and being straight about it is more useful than implying free export is unmarked. If watermark-free output is what you need, the pricing page lays out the weekly, monthly, annual, and one-time Lifetime options.
Plenty of real tasks fit entirely inside the no-cost path. These are the situations where the free tier is genuinely enough.
Scanning receipts, warranty cards, manuals, and household paperwork to keep digital copies for yourself. A small watermark on a file that only you will ever open does not matter. Scan, save to Files, done — no account, no subscription, no cloud detour.
A handout, a business card, a flyer with a date on it — the kind of paper that vanishes if you do not capture it now. Free scanning with auto-capture gets a clean, legible copy in seconds. Far better than a crooked Camera Roll snapshot, and it lives in your document library where you can find it again.
Because scanning and OCR run on-device with no upload, the free tier is a reasonable fit for things you do not want leaving your phone at all: an ID copy for your own emergency backup, a medical letter, a tax slip. Add Face ID, Touch ID, or a passcode lock on the app — also free — and the copy stays private to you.
On-device OCR is in the free tier, so you can recognize and copy text from a scanned page without paying — a phone number off a letter, an address off a form, a paragraph from a book. (Embedding that text permanently inside the PDF as a searchable layer is the separate Premium searchable PDF feature; reading and copying the text on screen is free.)
Yes — ScanLens is free to download from the App Store and you can start scanning immediately. Scanning, basic PDF export, and on-device OCR work without paying or creating an account. Free-tier exports carry a small ScanLens watermark; Premium removes it and unlocks the PDF tools. The full plan lineup, including a 7-day trial, lives on the pricing page.
No. No banners, no interstitials, no "watch an ad to continue" prompts. The app stays out of your way.
No — you can download and scan without creating an account. You only sign in if you choose to connect your own cloud storage.
Scans stay on your iPhone. Every OCR pass and signature placement happens on-device using Apple's Vision framework. Documents never reach a ScanLens server. Cloud sync only moves files when you connect your own Google Drive, Dropbox, OneDrive, or iCloud Drive.
Yes. PDF, JPG, and PNG exports from the free tier carry a small ScanLens watermark. The scan itself, the on-screen preview, and the on-device OCR are not affected — the watermark only appears on the exported file. Premium and the one-time Lifetime license remove it, producing a plain export with no mark. We state this up front rather than implying free export is watermark-free.
Yes, if the watermark on exports is acceptable for your use. Scanning with edge detection and auto-capture, ID and passport capture modes, crop and filter tools, multi-page documents, on-device OCR for reading text on screen, app lock with Face ID, and saving to Files or Photos are all available at no cost and with no account. You only need Premium for watermark-free export, searchable PDF, merge/split/compress, password protection, e-signatures, and third-party cloud sync.
On-device OCR — recognizing text from a scan so you can read or copy it on screen — runs in the free tier. Searchable PDF is a separate, Premium feature: it embeds that recognized text as an invisible layer inside the exported PDF, so the file becomes findable with Cmd-F or your phone's search later. Free OCR reads the text now; searchable PDF bakes it into the file for the future.
