Reduce Image to 40KB — Ideal for Scanned IDs and Documents
Need to resize your photo to 40KB for an official application? Our easy online tool helps you compress scanned IDs, Aadhaar cards, and Driver’s Licenses to the perfect size without making the text blurry or unreadable.
When you are signing up for things online, you will often run into a rule that says your ID — like your Aadhaar card, PAN card, Passport, or Driver’s License — has to be under 40KB.
Modern phones create very high-quality images, which also means bigger file sizes. Many government portals reject large uploads, so reducing the image size becomes necessary.
This tool helps you compress JPG, PNG, and WEBP images while keeping the text readable and clear.
Recommended Settings
- Dimensions: 300 × 400 pixels
- Format: JPG
- Quality: 75–85%
- Target Size: Around 38KB
Why Do Websites Require 40KB Images?
Government portals and job websites process millions of uploads every day. Smaller image files reduce server load and make uploads much faster.
Tips for Better Compression
- Crop unnecessary white space.
- Use JPG format for smaller file sizes.
- Keep image dimensions moderate.
- Use grayscale for scanned documents.
- Aim for 35–38KB to avoid upload rejection.
