A free CamScanner alternative with no ads or watermark

OpenDocScan is a free, open source CamScanner alternative: a document scanner that runs in the browser on your phone or laptop and turns a photo of a page into a straightened, searchable PDF. Unlike CamScanner, a scanner app whose free version shows ads and adds a watermark until you upgrade, it has no paid tier, no ads and no watermark, and the pages are never uploaded.

When CamScanner is the better choice

A CamScanner alternative is not always the right pick. Choose CamScanner if:

You want an app from the app store. CamScanner is on iOS, Android, HarmonyOS, Windows, macOS and the web [7]. The OpenDocScan iPhone, iPad and Android apps are still in progress, with nothing to download yet [5].
Your documents are not in English. OpenDocScan's text recognition reads English only for now [5][6].
You want your scans on every device. CamScanner syncs across platforms, with 1 GB of cloud storage free and 10 GB on Premium [2]. OpenDocScan keeps scans in one browser on one device [6].
You need more than a scan. CamScanner lists an ID scan mode, electronic signatures, image to Word and Excel, and team folder sharing [2]. OpenDocScan makes a searchable PDF and stops there.

When this CamScanner alternative fits better

You want no ads and no watermark, free. CamScanner says to “Upgrade to Premium to remove ads and watermarks” [1]. This CamScanner alternative has no paid tier: every feature is free, with no page limit, no watermark, no trial and no account [6].
You would rather not upload your documents. When you use CamScanner's text recognition or cloud sync, its privacy policy says it collects the files you choose to take or upload [4]. OpenDocScan finds the page, straightens it, reads the text and writes the PDF inside the tab; nothing is uploaded [5][6].
You want to check that for yourself. Open the Network panel in the developer tools and scan a page: after the app has loaded, nothing else is requested [6].
You want to read the code. The source is on GitLab under MIT or Apache-2.0 [8].

What this CamScanner alternative does not do

This CamScanner alternative reads English only. A page in Chinese, Japanese or Korean still scans and exports cleanly, but gets no searchable text layer, and the scanner says so instead of guessing.
No sync and no cloud copy. Scans live in this browser on this device. Clearing your browsing data for the site deletes them, so export the PDFs you want to keep.
No app store download yet. On a phone, use the browser and add the scanner to your home screen; it then opens like an app and works offline.
No ID card mode, signatures or Word export. The output is a PDF: A4, US Letter, US Legal, or the shape of the scan.

Try this CamScanner alternative

Open the scanner, photograph the first page, add the rest, and save one PDF. The scan to PDF guide walks through it step by step, and scanning multiple pages into one PDF covers longer documents. OpenDocScan is not affiliated with CamScanner or INTSIG. Questions: hello@opendocscan.com.
