Step by step
How to Resize an Image to 20 KB
- 1
Add your photo
Drop a JPG, PNG, WebP or iPhone HEIC image on the box, paste it, or tap to pick it. The Under 20 KB limit is already chosen.
- 2
Set the size if your form asks
Keep the original width and height, or tap a preset such as 300 × 300 px. Small sizes like 300 × 300 px or 300 × 80 px stay much sharper at 20 KB.

Check the result
The quality is tuned automatically so the file fits under 20 KB. The new size in KB is shown under the preview.

Download
Tap Download JPG. The image is made on your device and never uploaded.
FAQ
Resize image to 20 KB: questions and answers
How do I reduce an image to 20 KB?
Add the image on this page: the Under 20 KB limit is already selected, so the tool finds the highest JPG quality that fits and shows the exact size before you download. Tap another limit or type your own if you need a different one.
What size in pixels fits under 20 KB?
A 300 × 300 px photo or a 300 × 80 px signature fits under 20 KB in good quality. A full phone photo (4000 × 3000 px) has to be made much smaller first, so tap a preset or type a width such as 400 px.
Why did my image get smaller in pixels to reach 20 KB?
If the image is very large or detailed, even the lowest sensible quality can't fit under 20 KB at that width and height. The tool then scales it down just enough to fit and tells you the new size. Picking a smaller size first, such as 600 px wide, keeps more quality.
Is my photo uploaded to a server?
No. The image is resized inside your web browser on your own device, so 0 bytes are uploaded and nothing is stored. It even works offline once the page has loaded.
