How to use the Compress Image to 20KB
- Drop your images into the box, click to choose them, or paste a screenshot with Ctrl+V.
- The target size is already set to 20 KB. Choose JPEG or WebP as the output format.
- Click Compress Image. The tool tries the highest quality that fits, and makes the picture slightly smaller only if it has to.
- Check the size shown next to your picture, then click Download.
Features
- Gets your image to 20 KB or less, the way many online forms and portals ask for it.
- Keeps the highest quality that still fits. It only reduces the picture dimensions when lowering the quality is not enough.
- Your original is kept as it is when it is already under 20 KB and in the right format.
- Several images at once (up to 20) with a ZIP download.
- Runs in your browser: no upload, no signup, no watermark.
When to use this tool
- Signature and stamp images for application forms.
- Small passport or ID photos when a portal has a very low limit.
- Thumbnails and avatars.
- Email signatures and tiny web graphics.
How the size is measured
20 KB means 20,480 bytes (1 KB = 1,024 bytes). The result is at or under this number. If you need a file that is close to 20 KB but not far below it, upload a larger original, because a small picture can not be made bigger without losing quality.
Frequently Asked Questions
How do I reduce an image to 20 KB?
Add your image, click Compress Image and download the result. The tool lowers the quality, and the dimensions if needed, until the file is 20 KB or less.
Are my images uploaded to a server?
No. Everything runs inside your browser, so your pictures never leave your device.
Why does my picture look smaller or softer?
To reach 20 KB, the tool may need to reduce the quality or the pixel size of large photos. A 20 KB target is small for a big photo, so some loss of detail is normal.
Can the tool fail to reach 20 KB?
For very large or very detailed pictures with a very small target it can fail. The tool then shows the smallest file it could make and tells you the target was not reached. Try a smaller original, for example by cropping it first.
What if my file is already under 20 KB?
The tool keeps your original file if it is already under the target and in the right format. A PNG file is converted to JPEG when JPEG is required.
Which format is used?
You choose between JPEG and WebP. JPEG works everywhere. WebP is smaller at the same quality, but some old programs and websites do not accept it.
