How to Resize and Compress Scanned Photos Under 20KB

1. Resizing for Tiny Upload Limits

Many government exams require a photo and signature under 20KB. Meeting this limit requires reducing pixel dimensions (e.g. to 200x230px) and adjusting the JPEG compression quality.

2. Target Size Compression

Our tool uses a canvas-based loop. Enter '20' as the target KB size, and the script balances resolution and compression quality locally to generate a compliant image instantly.

2.1 Balancing Dimensions and Compression

Shrinking image dimensions first (e.g. to 150x200px) allows you to reduce file size while keeping the text and details legible.

Will the photo lose quality at 20KB?

By shrinking the resolution first (e.g. to 150x200px), you preserve high legibility while keeping the size small.
