How to Resize a Photo to 20 KB (Without Losing Quality)

Many government forms, job applications, and online portals require photos under a specific file size — often 20 KB, 50 KB, or 100 KB. This is far smaller than what modern phone cameras produce (typically 3-8 MB), so compression is necessary.

Why file size limits exist

Online submission portals have bandwidth and storage constraints. Government systems, particularly in South Asia, often enforce strict limits: Indian passport applications cap at 250 KB, some Indian university forms require under 20 KB, and many competitive exam portals set 50 KB limits.

The quality tradeoff

Reducing a photo from 5 MB to 20 KB means compressing by 250×. At this compression level, visible quality loss is inevitable. The key is minimizing that loss:

Step 1: Resize dimensions first. A 4000×3000 photo compressed to 20 KB looks terrible. A 200×250 photo compressed to 20 KB looks acceptable. Always reduce pixel dimensions before targeting file size.

Step 2: Use JPEG format. JPEG compression is far more efficient than PNG for photographs. If your source is PNG, convert to JPEG first.

Step 3: Reduce quality gradually. Start at 80% JPEG quality and decrease until you hit the target file size. The ExactPix compressor does this automatically.

Common target sizes

Use ExactPix

Upload your photo on any of our spec pages — the tool automatically compresses to the required file size for that specific application. Or use our universal compressor to target any custom file size.
