How to compress an image to 20 KB
- Click Select image and choose your photo, scan or signature. JPG, PNG and WebP all work.
- The target is already set to 20 KB. Move the slider or type a number if your form asks for a different size.
- Click Compress to 20 KB, check the before and after, then click Download.
Where 20 KB is asked for
20 KB is one of the most common limits on Indian exam and recruitment forms. Portals such as SSC and IBPS have often asked for a signature between 10 and 20 KB, and some forms set 20 KB as the minimum or maximum for the photo too. Limits change from one notice to the next, so check the size and the pixel dimensions in your official instructions before you upload.
Tips for a clean 20 KB file
- Crop first. A signature or face that fills the frame stays sharp at 20 KB. Use Crop image to cut away empty paper or background.
- Scan signatures on white paper with dark ink. Plain white compresses very well, leaving more of the 20 KB for the signature itself.
- Expect a smaller image. A phone photo has millions of pixels, far more than 20 KB can hold sharply. The tool shrinks it to a size that still looks clear, usually a few hundred pixels across, which is what these forms expect.
- If the form also sets pixel sizes, resize to them with Resize image first, then compress here.
