How to resize an Aadhaar card image — step by step
About the Aadhaar card resizer
The Aadhaar card sticks to the worldwide ID-1 format — 8.56 × 5.40 cm — which translates to 1011 × 638 px once you set a print-ready 300 DPI. Nailing the pixels and the file weight together really counts when you're printing: an off-spec image ends up stretched or fuzzy, and portals turn back anything that doesn't fit the published requirements.
Because the work is handled in your browser by HTML5 Canvas, your Aadhaar image stays put on the device you're using. Nothing gets parked in the cloud, nothing lands in a server log, and there's no privacy cost.
- Work from a high-resolution scan so the text stays legible at 1011 × 638 px.
- Trim right up to the card's edges before you resize.
- Keep the output inside the 20–300 KB band to stay crisp and readable.
- When printing the card, run it through a 300 DPI printer.
