Compress image to 20 KB
Signatures and photos for government, exam and job forms that cap uploads at 20 KB.
How to compress a photo to 20 KB
- Set the size. It is already set to 20 KB. You can change it above.
- Add your photo. Drag it in, choose it, or paste a screenshot. You can add several at once.
- Download. Each result shows its final size, quality and dimensions.
Very small limits like 20 KB usually mean a small photo or a signature. The tool lowers quality first, then size, until the file fits, so faces and writing stay as clear as possible.
Tips for the best result
- Crop first. Cutting away background leaves more of the size limit for your face or document. Use the Image Cropper or the Passport Photo Maker.
- Need exact pixels too? Some forms ask for both, such as 200 × 230 px under 50 KB. Resize with the Image Resizer, then compress here.
- Got an iPhone HEIC photo? Convert it with HEIC to JPG first.

Frequently asked questions
How do I compress an image to 20 KB?
Add your photo, and it is reduced to under 20 KB automatically. Then download it. The tool tries the highest quality that fits before it makes the picture smaller.
Will the photo still look good?
The tool keeps as much quality as the size allows. It first lowers JPG quality, and only reduces the width and height when that is not enough. You can see the final quality and dimensions before you download.
Is my photo uploaded anywhere?
No. Everything happens in your browser on your own device. Your photo is never sent to a server, so it is safe for ID photos and documents.
What format is the result?
A JPG file, because almost every online form accepts JPG. Transparent areas are filled with white.
The form says "KB" but my file is slightly over. Why?
Some sites count 1 KB as 1,000 bytes and others as 1,024. The tool aims a little under the limit, measured in 1,000-byte KB, so the file passes either way.
