Why 20KB is harder than ordinary compression
A hard byte ceiling may require both quality reduction and dimension reduction. Once encoding quality becomes too low, reducing dimensions often gives a cleaner result.
Portal requirements change
Government, recruitment, university and KYC portals can use different size ranges, dimensions and formats. Read the current upload instructions and verify the downloaded file before submission.
Quick reference
What to remember
- 20KB is usually a maximum-size requirement, not the only requirement.
- Reducing dimensions can preserve quality better than forcing very low JPEG quality.
- Signatures usually compress more easily than detailed photos.
- The destination portal remains the source of truth for current submission rules.
What to avoid
- Optimising only KB while ignoring dimensions.
- Submitting PNG when JPG is required.
- Compressing a face or signature until important detail becomes unclear.
- Assuming every exam, recruitment or KYC portal uses identical rules.
