How to compress an image to 20 KB
- Press Choose image and select your photo (JPG, PNG or WebP).
- The target size is already set to 20 KB. You can change it if your form asks for something else.
- Press Compress & Download.
- Check the new size shown on the page. The file is saved as a JPG under 20 KB.
A 20 KB limit is very small. It is often asked for signature images and small passport-size photos on application forms. The tool first lowers the JPEG quality as far as is sensible and, if that is still not enough, it also reduces the pixel size so the file fits under 20 KB. For the best result start with a photo that is already close to the size you need, for example 200 x 230 pixels.
Frequently asked questions
How do I compress an image to 20 KB?
Choose your photo, keep the target size at 20 KB and press Compress and Download. The tool searches for the best quality that stays at or under 20 KB and saves the result as a JPG.
Will the file be exactly 20 KB?
No. The tool finds the largest quality that stays at or under 20 KB, so the file is usually a little smaller than 20 KB, never above it.
Why did my picture also become smaller in pixels?
If lowering the quality alone cannot reach 20 KB, the tool also reduces the width and height. This is needed for large phone photos. If your form asks for exact pixels, use the Image Resizer first.
Is my photo uploaded anywhere?
No. The image is compressed inside your browser and is never sent to a server.
Can I use it for a signature or a small passport photo?
Yes. Many exam, job and government forms set a maximum size in KB for photos and signatures. Always follow the size and format your form asks for.
