How to compress an image to 20kb
- Check whether the recipient means KB (not pixels) and whether it sets a strict maximum.
- Choose the image and set the target to 20 KB.
- Download the result, then check the actual file size and readability. Leave a margin if the limit is strict.
Questions and answers
Will every image reach exactly 20KB?
No. The compressor searches JPEG quality settings and aims for the target; some images cannot reach it without excessive quality loss.
Will the image dimensions change?
No. The target-size control changes JPEG quality. Resize the image first only if the recipient allows different pixel dimensions.
Why leave a little room below the limit?
Upload systems can enforce a strict maximum, and rounded size displays may differ. Check the downloaded file rather than relying on the target entry alone.
