Resize image to 20 KB
Shrink any photo, signature or scan to 20 KB or under for forms and uploads, at the sharpest quality that fits.
How to resize an image to 20 KB
1. Choose your photo, signature or document scan. 2. Set the maximum size in KB. 3. If the form asks for exact dimensions (for example 200×230 px for a photo or 140×60 px for a signature), enter them too. 4. Tap the button and download. The result is always at or under your target.
The tool finds the highest JPG quality that fits the limit. If the image still doesn't fit, it shrinks the dimensions step by step until it does, keeping the photo as sharp as possible.
20 KB is a common limit for passport-style photos and signatures on government and exam applications. For a clear face at 20 KB, crop to head and shoulders first.
