How to use it
- 20 KB is already selected — just tap “Select Photos” and pick your image (JPG, PNG, WebP or HEIC).
- Wait a second while the photo is compressed to 20 KB or just under it.
- Check the preview and the new size, then tap “Download”.
When do you need a 20 KB image?
Signatures are the most common reason. Most bank and government exam forms ask for a signature between 10 and 20 KB. 20 KB is also the minimum size for photos in many forms that use a 20–50 KB range — so if your photo is getting rejected as “too large”, 20 KB is a safe floor to try.
Getting a clean 20 KB signature
- Sign with a black pen on plain white paper.
- Take the photo in daylight, straight from above, without shadows.
- Crop tightly around the signature before compressing — less empty paper means sharper ink.
