Best PDF Scanning Apps in 2026: 8 Apps Compared

Adobe describes Adobe Scan as completely free to download, and the app covers the basics well. It corrects perspective, sharpens text and reduces glare and shadows, then saves the result as a searchable PDF. Files can be sorted into folders, shared by link or email, or sent to cloud apps.

The catch sits behind the paywall. Adobe's page says features such as combining files and password protection need a trial of Acrobat Pro, and the iOS listing says paid subscriptions raise OCR capacity from 5 to 100 pages. The same listing shows a 4.9 rating from about 1.6 million ratings on iOS.

This is the one we would try first. It runs on iOS 15 or later and Android 8.0 or later, and anything you scan shows up in Acrobat once you sign in with an Adobe ID.

Genius Scan is the easiest app here to understand financially. The pricing page lists a free Basic plan described as a fully functional scanner with unlimited scans, and an Ultra plan at $39.99 per year. Ultra adds OCR, export to major cloud providers, enhanced security, unlimited cloud backups, cross-device sync, storage saving and web access.

The scanning itself covers automatic document detection, perspective correction and color enhancement. You can add pages, rearrange them, merge documents and tag them for search later. A team plan is listed at $40 to $20 per license per year, with volume discounts.

The honest downside is that searchable text is not free. If you need OCR every week, count on Ultra. If you mostly scan receipts and forms to email, Basic may be enough.

Scanner Pro from Readdle is the polished choice for Apple households. It scans documents, receipts, IDs, business cards and printed photos, then lets you crop, merge pages, erase marks, sign and annotate. It also offers OCR, PDF password protection, QR capture and iCloud backup.

Pricing is the weak spot. The iOS listing calls the app free with in-app purchases and shows rows labeled Scanner Pro Plus at several prices between $3.99 and $59.99, without saying which is which. Readdle's own site shows no price, so check the in-app screen for the current Plus plan and any trial before you subscribe.

The listing shows a 4.9 rating from about 337,000 ratings. We would pick it over cheaper options if you live in the Apple ecosystem and want one scanner on every device.

CamScanner, from INTSIG, is the feature-heavy veteran. Its site lists iOS, Android, HarmonyOS, macOS, Windows and web versions. Beyond scanning, it handles page merging and splitting, e-signatures, watermarks, compression, and conversion between PDF, Word, Excel, PowerPoint and JPG.

The free version covers basic scanning, saving, sharing and uploading, with limited OCR. CamScanner's FAQ says to upgrade to Premium to remove ads and watermarks, which is a real consideration if you send scans to clients. The iOS listing shows Premium options at many price points, including a one-week plan at $9.99, plus a 4.8 rating from about 2 million ratings.

It earns a place for breadth. Just check the plan length and renewal terms on the purchase screen, because the list of tiers is long.

SwiftScan, made by Maple Media Apps, leans on privacy and utility. Its site says text recognition happens on the device and that no data in your documents is sent to the company or a third party. It captures at 200+ dpi, offers five color modes, and can fax at one credit per page to more than 50 countries.

On iOS the listing shows AI summaries and translation, annotations, e-signatures, redaction, and WebDAV, FTP and SFTP uploads. The site links to a seven-day free promotion. The plans in the listing include a VIP annual tier at $34.99 and a Plus annual tier at $59.99, but the page repeats some names at different prices, so confirm in the app.

Read the App Store privacy label alongside the site's privacy claims, since the label lists some data types such as identifiers and usage data. The iOS listing shows a 4.8 rating from about 19,000 ratings.

The Google Drive app has a scanner built in, and for many people it is enough. Google's help page says that on Android you tap the camera icon, photograph the page, then crop, rotate, apply filters, clean up stains, add or retake pages and name the file. You can save as PDF or JPG, and the page describes the results as searchable PDFs. The help page also has separate steps for iPhone and iPad.

Every Google account includes 15 GB of free storage, shared across Gmail, Drive and Photos. There is no separate scanner subscription, which makes this the simplest route when a form just needs to land in a folder.

The trade-off is depth. You will not find merge-and-sign tools, ID modes or fax credits here, so power users will want a dedicated app.

If you relied on Microsoft Lens, note that Microsoft retired it. Its support page says the app was removed from the app stores on November 15, 2025, and that creating new scans stopped after December 15, 2025. Microsoft points users to the scan feature in the Microsoft 365 Copilot app, and the OneDrive mobile app also scans.

According to Microsoft's OneDrive scanning page, you tap the camera icon in the mobile app to turn documents, receipts, whiteboards and ID cards into PDFs, then mark them up. The page lists 5 GB of free storage with the mobile app.

OneDrive is a sensible pick when your files already live in Microsoft 365. Reports note that some Lens features, such as direct saving to OneNote and business card scanning, are missing in Copilot, so check that your workflow still fits.

Dropbox offers a document scanner inside its iOS and Android apps. You tap the plus icon, choose Scan Document, and the result is saved as a PDF in your Dropbox. You can add pages, apply filters, reorder pages, rename the file and pick where it saves. Dropbox says the scanner is free for all users.

The limits are plan-related. Dropbox lists OCR text search for Standard, Advanced and Enterprise plans, and its page does not say whether Plus includes it. The Basic plan includes 2 GB of storage, and Plus is $9.99 per month for 2 TB.

It makes the most sense when Dropbox is already your filing cabinet. If it is not, start with one of the dedicated scanners above instead.
