FAQ
Which format is best for a 20KB exam upload?
JPEG works best for tight size limits like 20KB. PNG is lossless and usually stays above the limit.
Does my image leave my browser?
No. Images are processed in your browser, so your image never leaves your device.
Common situations for this workflow
Government exam portals (SSC, UPSC, banking) that cap photo or signature size at 20KB.
Online registration forms that reject any image larger than 20KB.
Scanned signature uploads that must stay well under a small KB limit.
Checklist before you upload
Start with JPEG - it reaches a 20KB target far more reliably than PNG.
Reduce dimensions if compression alone cannot reach 20KB cleanly.
Verify both the final file size and the required format before uploading.
Tips to hit the target faster
20KB is a tight limit, so simple backgrounds and tightly cropped portraits compress more reliably.
For exam photos, downscaling resolution usually matters more than tiny quality tweaks.
Good for exam and signature uploads - aim slightly under 20KB so strict portals still accept it.
