Quick answer
To put Aadhaar front and back in one PDF, add both photos to Images to PDF and download. To fit both sides on one page, run that PDF through Pages per sheet with 2 per sheet. Finish with Compress PDF if the form has a size limit.
Why do forms want both sides in one file?
Bank KYC, SIM activation, rental agreements, admissions and many job portals allow only one upload for "address proof" or "ID proof". The front of the Aadhaar card has your photo and number; the back has your address. Putting both in one file means you don't miss either side.
How do I make one PDF from two photos?
- Take clear photos of the front and back on a plain, dark surface.
- Open Images to PDF and add both photos — front first.
- Choose A4 and a Small margin.
- Click Create PDF and download.
You now have a two-page PDF: page 1 is the front, page 2 is the back.
How do I put both sides on one page?
- Open Pages per sheet and add the two-page PDF.
- Choose 2 pages per sheet.
- Download. Both sides now sit on a single page, which is how most offices prefer a printout.
Already have them as two separate PDFs?
Use Merge PDF to join them first, then follow the one-page steps above.
How do I keep it under the upload limit?
Run the final file through Compress PDF with Strong and grayscale on. Front and back on one page usually comes out at 60–150 KB.
Should I share the full Aadhaar number?
Only if the organisation actually needs it. For most uses you can share a masked Aadhaar that shows just the last four digits. See how to mask your Aadhaar number in a PDF.
