Preparing your workspace
Loading securely
LoadingA free download is not the same as a free app. Before you install, check these five things:
No watermark. A logo stamped on every page makes a PDF useless for job applications, contracts or school work.
Unlimited scans. Some apps cap pages per document or scans per month.
No forced account. An account usually means your scans are uploaded to someone's cloud.
Where your files live. Apps that store scans on your phone keep them private by default.
What's behind the paywall. OCR, merging PDFs and exporting to Word are the features most often locked.
It also helps to know that both iPhone and Android can already scan documents with built-in tools. A dedicated app earns its place with what comes after the scan: text recognition, batch scanning, sync and control over where documents go.
ScanMint AI turns your phone into a document scanner and adds a full PDF and productivity toolkit on top. You can scan to PDF, sign documents, convert files and share them, with no account and no watermark.
What sets it apart is everything around the scan. ScanMint AI bundles 18 tools in one app, including a QR code generator, barcode generator, speech to text and a text counter. Most scanner apps only read QR codes; ScanMint AI lets you create them.
Privacy: Your scans, PDFs and signatures stay on your device and are never uploaded to our servers.
Pricing: Free to use. Premium removes ads and unlocks every tool, or you can unlock a single tool for free by watching a short ad.
Pros: No account, no watermark, local storage, QR and barcode generator, speech to text, Material You design with dark mode
Cons: No OCR yet, Android only, fewer cloud export options than older apps
vFlat Scan offers unlimited scans with no watermarks, ads or sign-in, plus free text recognition. It shines with books: it flattens curved pages, removes your fingers from the shot and captures two-page spreads at once.
Pros: Free OCR, excellent book scanning, auto-capture
Cons: Fewer PDF editing tools, heavy OCR use needs paid credits
Genius Scan works fully offline and is ad-free. The free Basic plan is unlimited with no watermark. OCR, cloud export and encryption need Ultra at $39.99 a year.
Pros: Very fast, private by default, no ads
Cons: No free OCR, annual billing only
Adobe Scan detects edges automatically and creates searchable PDFs that open straight in Acrobat. The free tier is limited, though: OCR is capped at 5 pages per file, and merging scans or exporting to Word needs a paid plan.
Pros: Accurate scanning, trusted brand, free OCR on short documents
Cons: Needs an Adobe account, key features paywalled
iScanner includes a free document editor for e-signing, merging, splitting, annotating and watermarking. Multi-page OCR and cloud features require the Pro subscription.
Pros: Strong editing tools, AI page straightening
Cons: Advanced features need a subscription
CamScanner is one of the most feature-rich scanners available. On the free plan, reviewers report intrusive ads and a watermark on exported documents. Premium costs $4.99 a month, or $49.99 a year after the first year.
Pros: Deep feature set, good image enhancement
Cons: Watermark and ads on the free plan, pricey premium
TapScanner offers a full PDF workspace and OCR in over 110 languages. Some users find it pushes the premium plan hard, and the free version is limited beyond single pages.
Pros: Wide language support, batch scanning
Cons: Aggressive upsells, limited free tier
If you only scan a few documents a month, the scanner already on your phone may be enough. Google Drive on Android and Apple Notes on iPhone scan to PDF for free.
Pros: Already installed, completely free
Cons: Few editing tools, scans tied to your Google or Apple account

In 2019, CamScanner was briefly removed from Google Play after a malicious ad library was found in the app. The library was removed and the app restored. If you prefer extra caution, choose an app that stores scans locally and needs no account.
You don't need to pay for a good scanner app in 2026. Avoid apps that watermark your PDFs or force an account, and pick based on what you do after the scan.
If you want one app that scans, signs, converts and creates QR codes without uploading your documents anywhere, download ScanMint AI free on Google Play.
