About Resize Image to KB
Compress a photo or signature to an exact file size — like 20KB, 50KB, or 100KB — to meet the limits on exam, job, passport, banking, and government portal upload forms. Pick a target size, and the tool automatically adjusts quality (and dimensions if needed) to land just under your limit. Everything runs in your browser, so your documents are never uploaded to a server.

Frequently Asked Questions
Why do exam and job forms need photos under a certain KB?
Government and exam portals (SSC, UPSC, banking, passport, university forms) cap upload size — often 20KB–100KB for photos and 10KB–50KB for signatures — to save storage and bandwidth. This tool hits those limits exactly.
How does it reach the exact size?
It binary-searches the JPG/WebP quality to find the largest version that stays under your target. If quality alone can't get there, it optionally shrinks the dimensions until it fits.
Will my photo look bad at 20KB?
Very small targets reduce quality, but the tool keeps the highest quality that fits. For strict limits, WebP usually looks better than JPG at the same size.
Is my document uploaded anywhere?
No. All resizing happens in your browser, so your photo, signature, or document never leaves your device.
