Scanning a document with a phone is a solved problem — the question is what it costs you. Most of the good ones are apps that want an account; the free web tools tend to cap you per day; a couple stamp a watermark on the file unless you pay. We checked 11 by name on 4 September 2026, from the household names to the ones only book-scanners and iPhone owners know about. ScanReviver is ours; the rest you can verify on their own pages.
Your file is deleted the moment it's done. The big PDF sites keep your bank statements and IDs on their servers. Here the original goes right after processing, the result after 45 minutes — or sooner, on your click.

Clean a document now →Checked on each tool's own page and app store listing on 4 September 2026. "Best for" is the one job each tool is actually built around, not a marketing line.

The table above is the summary. This is the part most comparison pages skip — the specific thing each free tier will not let you do.
"Scan" and "OCR" get used interchangeably, and they are not the same thing. A scan is a clean photo of the page. OCR (optical character recognition) turns the letters in that photo into real, selectable, searchable text — the difference between a picture of a receipt and a receipt you can search for by amount.
Free and unlimited: Microsoft Lens and Adobe Scan. Both read text well and do not charge for it. Google Drive's scan can get OCR too, indirectly — open the resulting file with Google Docs and it converts the image to editable text, also free. Apple Notes can find and select text inside a scanned image (Live Text) but does not embed a text layer in the exported PDF the way a true OCR tool does.
Free with a cap, then paid: vFlat gives you roughly 100 pages of OCR before it asks for credits. Free but not the OCR: Genius Scan and SwiftScan both scan for free but put text recognition behind their paid upgrade. CamScanner and Scanner Pro read text as part of their paid tiers. TurboScan does not do OCR at all, free or paid — it is a scan-to-PDF tool, nothing more.
ScanReviver and any other browser-based scanner need a live connection: the cleanup happens on a server, so no signal means no scan. The native phone apps on this list — Genius Scan, CamScanner, Google Drive, Apple Notes, SwiftScan, Scanner Pro, vFlat and TurboScan — do the actual scanning and edge-cropping on the device itself, so you can scan on a plane or in a basement with no signal at all. You only need a connection afterward, to back the file up, sync it or share it. Microsoft Lens and Adobe Scan work the same way for the scan itself, but their OCR step can call out to the cloud depending on the language and file.
Each app defaults to a different home for the finished file, and that is worth knowing before you're locked into it. Microsoft Lens saves to OneDrive and plugs into Word/PowerPoint/Excel. Adobe Scan saves to Adobe Document Cloud and hands off cleanly into Acrobat. Google Drive's scanner saves straight into Drive, obviously. Apple Notes and Scanner Pro both default to iCloud, so they sync across your own Apple devices but do not hand the file to a third-party cloud on their own. CamScanner, Genius Scan, SwiftScan, vFlat and TurboScan keep files in the app itself first, with export or cloud-upload as a separate, sometimes paid, step. ScanReviver has no "home" at all — it hands you the finished PDF to download and deletes its own copy shortly after, which is the point of a tool with no account.
Stitching several pages into one PDF is table stakes — every tool on this list does it. What actually differs is the free-tier ceiling. TurboScan is the one with a hard number: 3 saved documents total on the free tier, regardless of how many pages each one has, before the one-time purchase unlocks the rest. vFlat's OCR specifically stops reading text after roughly 100 pages until you buy credits, though scanning itself keeps working. Every other tool here — ScanReviver, Microsoft Lens, Adobe Scan, Genius Scan, CamScanner, Google Drive, Apple Notes, SwiftScan and Scanner Pro — puts no cap on how many pages or documents you save for free; what they gate instead is a specific feature (OCR, cloud export, a clean watermark-free share).
Every paid step-up on this list, so there are no surprises if a free cap gets in your way:
Microsoft Lens, Google Drive and Apple Notes never charge a cent for the core scanning job described on this page. ScanReviver's core scan is free too, capped at 10 documents a day — a €5 pass raises that to 100 if you need more in one day.
None of this is really about the software. Three things decide whether the result looks scanned or photographed, and they all happen before you upload:
Get those right and every tool on this list produces something usable. Get them wrong and none of them can save it.
We opened each tool's own product page, pricing page and app store listing on 4 September 2026 and noted the free limits, account requirements, watermark policy and platform. We did not scan the same document with 11 tools and rank the output: the result depends far more on the light and the angle than on the software, as the section above explains.
Prices and free-tier caps on apps we do not control (CamScanner, Scanner Pro, SwiftScan, vFlat, TurboScan and the rest) can move without notice — that is normal for subscription apps. If one of these numbers is stale, mail [email protected] and we will fix it.
ScanReviver runs on our own hardware in the Netherlands. There is no account, and your upload is deleted right after processing with the PDF wiped 45 minutes later.
Our own scan to PDF tool turns any phone photo into a clean document, book page scanner handles curved pages without the usual glare, and receipt scanner is built for the small, faded print on receipts specifically.
Yes — no account, no app, no watermark, no charge to download. Ads on the page keep the server running.
For regular scanning, honestly yes: an app sees the page live through the camera and catches the edges before you take the shot. A browser tool works from the photo you already took. If you scan something once a month, that difference is not worth an install and an account.
ScanReviver can convert a PDF to Word, which extracts real text where the PDF has it. For OCR on a photographed page specifically, Microsoft Lens and Adobe Scan are the stronger free options — both do it well without paying.
ScanReviver, Microsoft Lens, Adobe Scan, Genius Scan, Google Drive's built-in scanner, Apple Notes, SwiftScan, vFlat and TurboScan all export clean, unmarked files on their free tier. CamScanner stamps free exports, and Scanner Pro adds a watermark unless you pay for Plus.
ScanReviver, Genius Scan, Apple Notes (it uses the Apple ID already on your device), SwiftScan, Scanner Pro, vFlat and TurboScan all work without signing up for anything new. Microsoft Lens, Adobe Scan, CamScanner and Google Drive's scanner need an account to save or sync your files.
Think first. Every browser tool here sends the file to a server. Ours deletes it immediately and stores no account, but if the document is genuinely sensitive, a phone app that processes on the device is the safer habit.
Uneven light. A shadow across half the page makes the cleanup guess wrong about what is paper and what is ink. Light from the side, phone directly above, and it fixes itself.
4 September 2026. Mail [email protected] if a limit here has moved.
Usually, yes — most people mean the same file either way. A scanner document to pdf conversion, ready to email or file, is what every tool on this list produces from a phone photo.
No — none of the browser-based tools here need document scanner software installed. ScanReviver, for instance, runs entirely as a web page; the phone apps in the list are the ones that install something.
ScanReviver runs as a document scanner online with no app; Adobe Scan and Microsoft Lens are apps first, though Adobe Scan also has a limited web uploader.
Automatic edge detection and perspective correction — a document photo scanner that finds the four corners of the page and straightens it saves you from framing every photo dead square yourself. ScanReviver and Adobe Scan both do this automatically.
Not on ScanReviver — scan the page here, then run the result through PDF to Word. Microsoft Lens can export to Word directly from the camera in one step.
Yes — ScanReviver is exactly that kind of pdf document scanner: it cleans and straightens the page and gives you a PDF, without trying to also read the text.
