Aadhaar Card PDF Requirements for KYC & Portals

January 28, 2026·4 min read·phototopdf.in

When applying for a bank account, a new SIM card, a passport, or any government service in India, you are almost always required to upload a copy of your Aadhaar card. However, simply taking a photo of your Aadhaar is rarely enough. Most portals require a specific PDF format.

Why Portals Require PDF Format

Government and banking portals prefer PDF files over JPG or PNG images for several reasons:

  • Both Sides in One File: An Aadhaar card has crucial information on both the front (Name, DOB, Photo, Aadhaar Number) and the back (Address). A PDF allows you to combine both sides into a single document.
  • Standardized Size: PDFs can be easily formatted to A4 size, which is the standard for printing and filing official documents.
  • Better Compression: PDFs can often compress text and images better than standard image formats while maintaining readability.

Common Aadhaar Upload Requirements

While requirements vary slightly between portals, these are the most common specifications you will encounter:

How to Combine Front and Back

To create a single PDF with both sides of your Aadhaar card, take a clear photo of the front and a separate photo of the back. Upload both photos to our Aadhaar to PDF tool. It will automatically place the front on page 1 and the back on page 2 of the generated PDF.

Frequently Asked Questions

Can I just upload two separate JPGs for my Aadhaar?

Most bank and government portals only provide a single upload button. If you don't combine the front and back into one PDF, you can't submit both sides.

What is the best file size for an Aadhaar PDF?

Aim for between 200KB and 500KB. This is the sweet spot that almost all Indian portals accept while keeping the text completely readable.

Is it safe to upload my Aadhaar card to a converter website?

It is only safe if the converter processes the file locally on your device, like phototopdf.in. Never use a converter that uploads your Aadhaar to an external server.
