Compress Image to Any Size in KB
Compress an image to any size in KB, free. Reduce the file size of a JPG, PNG or WebP picture or screenshot. It runs in your browser, so nothing is uploaded.
How it works
- Choose your image. It opens on your own device and is not sent anywhere.
- The tool finds the best JPG quality that stays under the limit on the slider, and only shrinks the pixel size if quality alone is not enough.
- If your form asks for exact pixels or a minimum size, open "More options". The image is cropped from the centre to match the pixel size.
Reducing image size without losing what matters
Crop away anything you do not need before compressing. Screenshots and flat graphics shrink far more than photographs, so a photo may need a larger limit to stay sharp. PNG and WebP files are converted to JPG, which is what makes them smaller.
Questions
Is my file uploaded to a server?
No. All the work happens inside your browser. The file never leaves your phone or computer.
What format is the result?
JPG (also written JPEG), which is what almost every application form accepts. PNG and WebP pictures are converted for you.
Will the image look blurry?
The tool keeps the highest quality that fits under your limit. A very small limit on a large, detailed picture will lose some sharpness.
Does it work on a phone?
Yes. It works in the browser on Android and iPhone, with nothing to install.
