PAN Card applications on NSDL require a photo and signature each under 20 KB. NDA and CDS applications via UPSC, RRB NTPC signature uploads, MPSC signature, and several state PSC signature fields also require 20 KB or less.

The key is combining dimension reduction with JPEG compression. For a 213×213 px image, JPEG quality of 65–75% typically produces a file between 8–18 KB — well within the limit while remaining clear enough for identity verification. Use the quality slider and the KB meter above to find the sweet spot.

Yes. A typical smartphone photo is 3–8 MB. By resizing it to 213×213 px and compressing at 70% JPEG quality, you can bring it down to 10–18 KB — a 99%+ reduction. The tool handles this in under 3 seconds entirely in your browser.

PNG is a lossless format — it cannot be compressed below a certain size based on pixel content. A 213×213 px PNG will typically be 30–80 KB regardless of settings. Always use JPEG for small KB targets like 20 KB. Government portals also usually mandate JPEG explicitly.

Try two things: (1) lower the quality slider to 60–65%, and (2) reduce the pixel dimensions slightly (e.g. from 213×213 to 180×180). The KB meter shows your current output size in real time after each resize. Keep adjusting until the bar turns green.

Yes. The output is a standard JPEG file with no watermarks, no embedded metadata added by this tool, and the filename is clean (e.g. pan-photo.jpg). It is identical in format to a file produced by Photoshop or any professional tool.
