iAbout Compress Image to KB
Shrink any image to a specific file size limit that upload forms require. Pick a target like 20KB, 50KB, or 100KB (or enter your own) and the tool binary-searches the JPEG quality — and optionally the dimensions — until the image fits under your target while staying as clear as possible. Ideal for government, exam, visa, and job portal photo uploads. Runs entirely in your browser; nothing is uploaded.

?FAQ
Can I compress an image to exactly 20KB?
Yes — choose 20KB (or any target) and the tool lowers quality, and shrinks dimensions if you allow it, until the file is under that size.
Will the image still be clear?
It keeps the best quality that fits under your target. Higher targets look sharper; very small targets like 10KB will look softer.
What formats are supported?
JPG, PNG, and WebP go in; the compressed output is a JPG (smallest at a target size).
