Key takeaways
- Modern browsers can use the camera, so a full scanner can run inside a web page.
- Osd-Scan processes everything in the browser — files are never uploaded.
- It works offline after the first visit and on borrowed or work phones where you can't install apps.
- Add the site to your home screen for one-tap access.
You don't always want another app: storage is full, it's a work phone, or you just need one scan. Modern browsers can access the camera and run serious image processing, so a complete document scanner can live in a web page.
How to scan in the browser
- Open your browser and go to osd-scan.com/scan.
- Tap Scan with camera and allow camera access when asked.
- Hold the phone over the page. The blue outline follows the edges.
- Hold still — the page is captured automatically. Continue with more pages.
- Tap Done, review the pages and tap Save PDF.
The PDF is saved to your phone's downloads.
Nothing is uploaded
Most "online scanners" send your photo to their server, process it there and send back a PDF. That means a copy of your document exists on someone else's computer. Osd-Scan works differently: the scanning engine, OCR and PDF tools run inside your browser. Your files never leave the device. You can even turn on airplane mode after the page loads and it still works.
Works offline
After your first visit, the tools are stored in the browser cache. Next time, they open instantly — even without a connection.
Add it to your home screen
For one-tap access like an app:
- Android (Chrome): menu ⋮ › Add to Home screen.
- iPhone (Safari): Share › Add to Home Screen.
No camera? Import photos
If you already took photos, tap Import photos or PDF and choose them. Each photo is cropped, straightened and enhanced. Computers work too: drag photos from a folder onto the page.
When the app is better
The Osd-Scan app for Android and iOS adds a few extras: saving straight to a Downloads folder, opening files from other apps, a recent-files list and faster access. But for scanning quality, the browser and the app are identical.
Use it on a computer
On a laptop, open Scan to PDF and import photos taken with any camera — or use the webcam for a quick capture. All 24 PDF tools work in the browser too: merge, compress, sign and more.
A scanner that needs no installation, no account and no upload is the simplest way to turn paper into PDF — wherever you are.
Frequently asked questions
Is an online scanner safe for private documents?
It depends. Many online tools upload your files. Osd-Scan runs entirely in your browser, so nothing is sent to a server.
Which browsers are supported?
Recent versions of Chrome, Safari, Samsung Internet, Edge and Firefox on Android, iPhone and computers.
Why does the site ask for camera permission?
To show the live camera for scanning. You can allow it once or every time, and you can still import photos without it.
Does it work without internet?
After the first visit the tools are cached, so scanning keeps working offline.
