Resize Image to Exact KB Sizes (20KB, 50KB, 100KB, 200KB)
One of the most common challenges people face is resizing images to meet strict file size requirements set by government portals, job application forms, and educational institutions. Our tool specializes in precision targeting. You can resize image to 20KB for signature uploads, resize image to 50KB for passport-size photographs, resize image to 100KB for standard form submissions, or resize image to 200KB for higher-quality document uploads.

Better Than Canva & Adobe Express for Resizing
If you have tried to Canva resize image or use the Adobe Express resize image feature, you have likely encountered limitations. Canva's resize functionality is locked behind its Pro subscription, and Adobe resize image tools require creating an Adobe account and often process files on remote servers — raising privacy concerns for sensitive ID photos and signatures. ResizeImageInKb.com offers a superior alternative: target-KB compression (which neither Canva nor Adobe Express supports), full privacy with zero server uploads, government portal presets, and batch processing — all completely free, forever.
Resize Image in KB JPG Format

Whether your source image is a PNG screenshot, a WebP photograph, or a BMP scan, the tool converts and compresses it into a standards-compliant JPEG file at exactly the size you need.
