Does Adobe Scan do OCR, and where do the words go?

Last reviewed: October 29, 2026 · Markdown version

Yes. Adobe's own documentation for the app says that "By default, the app automatically converts image text in scans to actual text using the Optical Character Recognition (OCR) feature", and that "The default text recognition language is set to the language of your device." (Change settings — Adobe Scan for iOS, Adobe, read 29 October 2026.) The parts worth knowing before you rely on it are the page limit, the language setting, and where the finished PDF lives. This page is about the Adobe Scan phone app; Acrobat on a computer is covered in OCR a PDF in Adobe.

Where the text goes

Into the PDF Adobe Scan saves, and that PDF goes to Adobe's cloud storage. Adobe's Android page is direct: "By default, your scans are saved to Adobe cloud storage as PDF" (Configure Adobe Scan — Adobe Scan for Android, Adobe, read 29 October 2026). The store listing says the same for both phones: "Scans are automatically saved to Adobe Document Cloud" (Adobe Scan: PDF & Doc Scanner, App Store listing, read 29 October 2026). Signing in is part of that: Adobe lists "Get your files automatically saved on Adobe cloud storage" among the reasons to sign in (Top questions — Adobe Scan for iOS, Adobe, read 29 October 2026).

Adobe Scan itself only shows you the result. Its troubleshooting page says "While you can open and preview your OCR’ed scan in Adobe Scan, you need to install Acrobat Reader and tap Open in Acrobat to work with the text" (Troubleshoot — Adobe Scan for iOS, Adobe, read 29 October 2026). The settings pages offer to keep the original photos on the phone ("Save originals to Photos" on iPhone, "Save original images to Gallery" on Android), but those are images, not the searchable PDF.

The page limit, which Adobe's pages state two ways

OCR does not run on long scans unless you pay, and Adobe's own pages disagree about where the free line is:

The iPhone settings page: "OCR does not run on scans longer than 25 pages for general users. However, with paid subscription, you can run OCR for scans up to 100 pages" (the Change settings — Adobe Scan for iOS page).
The Android settings page gives the same sentence with "5 pages" (the Configure Adobe Scan page).
Both store listings advertise the subscription as a way to "Increase OCR capacity from 5 to 100 pages" (the App Store listing above, and the Adobe Scan: PDF Scanner App, Google Play listing, read 29 October 2026).

Read on 29 October 2026, so check the app's own screen for the current figure. Our reading of "does not run": a longer scan is still saved, just without recognised text.

The language setting, and why it can produce nothing

You can switch OCR off or change its language under Preferences: "To change text recognition language, tap Text recognition language and tap a desired language." The list on both settings pages is English, Dutch, Japanese, Finnish, Norwegian, Swedish, French, Spanish, Brazilian Portuguese, Italian, German, Traditional Chinese, Simplified Chinese, Korean, Turkish, Russian, Czech and Polish (the two settings pages above). No Indian language is on it. A mismatch is not a small error, according to Adobe: "If you’ve selected a language to recognize that doesn’t match the document language, OCR produces no output", and if the phone's own language is unsupported, "the default output is English" (the Troubleshoot page). What the OCR language setting does explains why engines work this way.

When some pages come out without text

Adobe's troubleshooting page lists the conditions that "may impair OCR quality": "A dark colored background", "A source document with multiple languages", "A rotated source document", lighting "too bright or dark", and, last, "A network connection and an Adobe cloud storage connection is required" (the Troubleshoot page). That last line is why a scan made with no signal may not be searchable yet; whether OCR works offline compares other apps on that point. The listings also describe a beta Digitize tool for notes written by hand. We have not tested it, and Adobe's help pages we read do not describe it.

Searching Adobe Scan PDFs on your phone

The Adobe Scan pages we read describe the cloud copy and the original photos, but not how to keep the recognised PDF itself on the phone (the settings and Top questions pages above), so check the app's share options for that. Once a copy of the PDF is on your phone, DocFind can search it on iPhone, iPad or Android without uploading it. It searches inside many PDFs at once and shows the file, the page and the surrounding text. A page Adobe already recognised is searched as it stands; a page that came out as a picture only, such as one past the page limit, is read on your device first. Its limits: it reads printed text, not handwriting; on Android it reads Latin-script scans only; and it searches the PDFs you give it, not your Adobe cloud storage.
