Resize Image to 20KB

Upload your image and the tool automatically lowers JPG quality until the file is at or just under 20KB, reducing the dimensions if needed. Then download it. No software to install.

A 20KB cap keeps a portal's storage and bandwidth low. It is one of the most common limits for exam, banking and signature uploads, and a clean image compresses to 20KB easily.

Reduce the pixel dimensions in the custom settings — fewer pixels means each one keeps more quality at 20KB. Cropping out empty background also helps a lot.

No. Every step — resizing, cropping and compression — happens locally in your browser using the HTML5 Canvas API. Your image never leaves your device, and nothing is stored or transmitted.

Open the "Need exact width, height or quality?" section and reduce the width and height — a smaller image reaches a tiny KB target far more easily. Make sure the output format is JPG, and start from the original photo rather than a screenshot. If a target is physically impossible, the tool shows the smallest clear result it can make instead of a broken file.

Choose JPG for photographs and most form uploads because it gives the smallest file size. Use PNG only when you need a transparent background or razor-sharp line art. WebP gives excellent compression but some older government portals do not accept it — check the form requirements first.
