About this Image Compressor
The Image Compressor shrinks, resizes and converts images between PNG, JPEG and WebP entirely in your browser. Drop in a heavy screenshot or photo, pick a quality, and download a web-ready file: the image is processed on your device and never uploaded to a server.
How to use the Image Compressor
- Drop an image onto the panel or pick one from your files.
- Set the target format, quality and optional max size.
- Compare the before and after sizes, then download the result.
Good to know
- WebP usually beats JPEG at the same visual quality, and every modern browser displays it.
- Screenshots with text stay sharper as PNG; photos compress far better as JPEG or WebP.
- Because nothing is uploaded, private screenshots and unreleased product images are safe to compress here.
