Online Image Compressor To 20kb Width And Height
Upload an image, adjust the compression level, and download the optimized result. This tool is designed to be simple, fast, and mobile-friendly.
Tip: Very small targets (like 20KB) may require higher compression and/or resizing, depending on the original image.
Compress your image
How it works
- Choose an image from your device.
- Adjust the compression level (higher = smaller file, but more quality loss).
- Click “Compress Image” and download the optimized file.
Why can’t every image become exactly 20KB?
The final size depends on resolution, colors, details, and the file format. Some images need resizing in addition to compression to reach very small sizes.
Does compression reduce quality?
Yes. Higher compression usually reduces file size more, but can also reduce sharpness and detail. Use the slider to find the best balance for your image.
Privacy
We recommend not uploading sensitive personal images. If your tool processes files on the server, consider adding a short note about how long uploads are stored (or if they are deleted immediately).
Image compression for web and mobile
Smaller image files load faster, improve user experience, and can help reduce bandwidth usage. This is useful for websites, forms, email attachments, and social media uploads.
Best practices
- Use the lowest file size that still looks good on your target device.
- For photos: JPG is usually smaller than PNG.
- For screenshots/logos: PNG may look cleaner, but can be larger.
- If you need very small sizes, reduce dimensions (width/height) too.
