About this tool
A 20 KB limit is common for photographs on many online application portals. This tool shrinks your picture to fit under 20 KB without you having to guess at quality settings. It tries different quality levels and, only when needed, reduces the dimensions slightly until the file is below the limit, then gives you the best result it found.
It is ideal for passport-size photos and signature uploads on exam or government portals. If you must keep the exact pixel dimensions, tick "Keep original dimensions" and only the quality will be lowered. Photos shrink best as JPG or WebP, while PNG is reduced with color palettes.
Everything happens in your browser, so personal photos and ID documents never leave your device.
Frequently asked questions

Add the image and the tool automatically lowers quality and size until it is under 20 KB. Download the result.
Will my image look bad at 20 KB?
For most photos it looks fine. Very large, detailed pictures squeezed into a very small size will lose some sharpness, which is unavoidable.
Can I keep the same dimensions?
Yes. Tick "Keep original dimensions". If that cannot reach the target, you will be told so.
Which format gives the smallest file?
WebP is smallest, then JPG. Some forms only accept JPG, so check the requirement first.
Is Resize Image to 20 KB really free?
Yes. You can use Resize Image to 20 KB as often as you like with no sign-up, no watermark and no daily limit.
Are my images uploaded to a server?
No. Resize Image to 20 KB runs entirely in your web browser, so your files stay on your own device and are never sent to DEWANARO or anyone else.
