How to compress an image to 20KB
- Choose your photo or drop it into the box.
- Keep the target at 20 KB, or change it to any size you need.
- Check the preview, then download the new file.
The tool tries the best JPEG quality that fits under your limit. If the quality alone is not enough, it reduces the image dimensions a little at a time until the file fits.
Why 20KB?
A 20KB limit is common for signature images, small ID photos and older exam or job portals. It is a tight budget, so fine detail will soften. For best results, crop the photo to the part you need before compressing, and use a plain background.
Questions
Is 20KB enough for a photo?
Yes for a small passport-style or signature image. For a detailed photo the result will look soft, so crop first or raise the target.
Will a signature stay readable?
Usually yes. Dark ink on a white background compresses very well at 20KB.
Is my image uploaded?
No. Everything runs in your browser tab and nothing is sent to a server.
Can I use a different size?
Yes. Type any number in the target box, for example 50, 100 or 200.
