Reaching exactly 20KB depends on the original image size, dimensions, format, transparency, and visual detail. If the target is too small, enable auto resize or choose WebP/JPG output.
What is an image compressor to 20KB?
An image compressor to 20KB reduces an image file so it is small enough for websites, online forms, school portals, job applications, government forms, email attachments, and document uploads.
This tool works inside your browser. It uses compression quality and optional resizing to reduce the final file size without uploading your image to a server.
How to compress an image to 20KB
- Choose or drag a JPG, PNG, or WebP image into the upload box.
- Keep the target size as 20KB or enter a custom target size.
- Select JPG for compatibility or WebP for smaller file size.
- Enable auto resize if the image is very large.
- Click “Compress Image” and download the result.
Best settings for small images
- Use JPG for photos, ID images, scanned photos, and general uploads.
- Use WebP when the website or form accepts WebP and you need a smaller file.
- Use PNG only when transparency or sharp graphics matter more than small size.
- Use max width between 600 and 1200 pixels for many upload forms.
- Enable auto resize when the original image is several MB or very large in dimensions.
Common use cases
