How do I scan both sides of an ID card into one PDF?

Photograph the front, tap Add page, photograph the back, and export. Both sides go into one PDF, in the order you choose. Pick Match the scan as the page size if you want each page to be card-shaped rather than A4 or Letter.

Is my ID card uploaded when I scan it?

No. Finding the card, straightening it, cleaning the image and writing the PDF all happen in the browser tab on your device. The scan is kept in this browser's storage, not on a server, and you can delete it from your scans at any time.

Is it free to scan ID cards here?

Yes. Every feature is free, with no page limit, no watermark, no trial and no account.

Does OpenDocScan verify an ID or check that it is genuine?

No. It makes a clean PDF copy of the card for you to keep or send. It does not check, verify or store identities.

Can I scan a passport or a driver's license the same way?

Yes. Any card or page the camera can see is scanned the same way. For a passport, photograph the photo page as a page of its own.

Guide

Scan ID cards to PDF, without uploading them

To scan an ID card, photograph the front and the back with your phone's camera in OpenDocScan and save both as one PDF. Used as an ID card scanner, it finds the edges of the card, straightens it, evens out the lighting and writes the PDF inside the browser tab. It is free, there is no app to install and no account, and the card is never uploaded: the image does not leave your device.

How to scan ID cards, front and back

Open the scanner. Go to opendocscan.com on your phone or laptop and allow the browser to use the camera.
Put the card on a plain, dark surface. The contrast gives the scanner a clean edge to find. Hold the phone straight above the card to avoid glare on a laminated surface.
Photograph the front. Tap Scan and capture. If the outline misses a rounded corner, drag the corner points onto the card.
Choose the look. Photo keeps the card's colours, which suits an ID with a portrait; Enhance and B&W make printed text crisper.
Photograph the back. Tap Add page and capture the other side, so both sides end up in one PDF.
Export. Under Export settings choose A4 or US Letter to have the card printed on a full sheet, or Match the scan to keep each page card-shaped. Then Save & export and Save PDF, or Share it where your browser supports sharing.

Already have photos of the card? Choose Import images and they are straightened and cleaned up the same way as a fresh scan.

Why scan ID cards somewhere that does not upload them

An identity document carries your name, date of birth, a photo and a document number: the details that are most useful to someone else. Most scanner apps send each photo to their servers to process it. When you scan ID cards here, the work happens inside the browser tab: the scanning core has no networking code compiled into it, and a service worker refuses any request bound for another origin. You can check it yourself: open the browser's developer tools, switch to the Network panel, and scan. After the app has loaded, nothing else is requested.

The finished scan is stored in this browser on this device, not in an account. To remove it, open the document and delete it; clearing your browsing data also clears it. Once you have sent or saved the PDF, there is no copy anywhere you did not put one.

What it is not

Not an ID verification tool. It makes a copy of the card. It does not read a chip, decode a barcode, check that a document is genuine, or confirm who you are.
Text recognition reads English. With OCR on, the printed Latin-script text on the card is made searchable in the PDF. Text in Chinese, Japanese or Korean is not read, and the scanner says so; the image is unaffected.
Check what you are allowed to copy. Some documents carry rules about copies. That is between you and whoever issued the card.

OpenDocScan is a free, open source document scanner that runs in the browser. The same steps work for a passport photo page, a driver's licence or an insurance card. For longer documents, see how to scan to PDF in your browser.
