Somebody asks for a copy of your Aadhaar or PAN card, so you put the card on the table, take a photo and send it. What arrives is a small tilted card floating in a large picture of your desk, your sleeve and whatever the card was lying on. It is readable if you zoom, but it is not a copy of a card — and if it is going into a file, a form or a print job, it is not good enough.
The fix is not to crop it by hand. It is to detect the four corners of the card, straighten the perspective and cut exactly to the card's real proportions.
Why a hand crop never quite works
When you crop in a gallery app you drag a rectangle. But the card in your photo is not a rectangle — it is a slightly squashed four-sided shape, because the camera was not perfectly square above it. Whatever rectangle you drag will either clip a corner off the card or keep a wedge of background along one edge. The tilt stays too.
Corner detection works differently. It finds where the card's four corners actually are, then stretches that shape back into a true rectangle. The tilt disappears, the background disappears, and the edges come out parallel.
The size an ID card should be
Aadhaar PVC cards, PAN cards, driving licences, most national ID cards and virtually every bank and office card are made to the same international size, called CR80:
| Measurement | Value |
|---|---|
| Width | 85.6 mm (about 3.37 in) |
| Height | 54 mm (about 2.13 in) |
| Aspect ratio | roughly 1.586 : 1 |
This matters because it lets a tool remove the last of the distortion. Once the corners are known, telling it "this is a CR80 card" produces a crop with exactly the right proportions, rather than proportions guessed from a photo taken at an angle.
How to crop an ID card photo
- Open the Auto Crop Scanner and choose the photo of the card.
- Check the blue outline sitting on the card. Drag any corner that is off — the magnifier shows you exactly where you are placing it.
- Press Next: Enhance.
- Set Page shape to ID card (Aadhaar / PAN / NID). This locks the crop to true card proportions.
- Choose Magic Colour so the card's printing, holograms and photo stay in colour while the background lighting is flattened out.
- Download the image, or add the back of the card as a second page and export both as one PDF.

Open the Auto Crop ScannerPhotographing a card so it crops cleanly
- Put the card on a contrasting surface. Most ID cards are pale, so a dark table, a dark cloth or a dark book cover makes the edges obvious. A white card on a white table is the hardest case there is.
- Leave a margin. Keep the whole card in frame with visible space around all four sides.
- Watch the glare. Laminated and PVC cards are shiny. Move so the reflection of the light falls off the card, and turn the flash off — flash almost always creates a bright patch over the photo or the number.
- Fill the frame. The card should be most of the picture. Detail you did not capture cannot be recovered later.
- Hold the phone flat. Directly above beats at an angle, even though the tilt can be corrected.
Both sides, one file
Most of the time whoever asked for your ID wants the front and the back. Sending two separate images invites one of them to get lost.
Scan the front, press Add page, scan the back, then Download PDF. You get one file with two pages in the right order — much easier to attach to an email or a portal upload than two loose photos.
If you need them side by side on paper instead, the PVC Card Layout tool places the front and back at true card size on an A4 sheet, ready to print and cut.
A word on sharing ID documents
An ID card image contains your number, your date of birth and your photograph. Before you send one:
- Send it only to a party who genuinely needs it, over a channel you trust.
- Where the recipient accepts it, a masked Aadhaar — which hides the first eight digits — is the safer thing to share.
- Delete the copy from your phone gallery and from chat threads once the work is done.
Frequently asked questions
Will this work on a Voter ID, driving licence or bank card?
Yes. Detection does not care what is printed on the card. Old paper Voter ID cards are portrait rather than landscape — crop them the same way and leave the page shape on Auto, since they are not CR80.
My card photo has glare across the number. Can the tool remove it?
No. A reflection has replaced the printing in those pixels, so there is nothing left to recover. Retake the photo with the light coming from the side.
Can I get the card at a size suitable for printing?
Downloads are produced at the full resolution the crop allows, so the more of the frame the card filled, the more detail you get. For printing several copies on one sheet, use the PVC Card Layout tool.
What is the difference between this and the ID Card Auto-Crop tool?
The ID Card Auto-Crop tool is one tap: it detects the card and hands back a cropped card at CR80 size. The Auto Crop Scanner gives you the corner handles, the filters and multi-page PDF export, so use it when you want to check or adjust the result.
Do I need an account?
No. Free use is subject to a daily limit per tool for visitors who are not signed in; a subscription removes it.
