This online Image Compressor reduces the file size of your pictures so they load faster and take up less space. It supports JPG, PNG, and WebP and lets you balance size against quality with a single slider. Because the compression is done in your browser, there is no waiting for uploads and no limit on how many images you process per day.
Frequently Asked Questions

This page compresses Image files. Compression re-encodes the image at a lower quality setting, discarding detail the eye is least likely to miss, and everything happens locally in your browser.
How it works
- Select your Image files — several at once is fine.
- Set the quality level and watch the estimated saving.
- Compare the preview against the original before committing.

Good to know
Image files respond differently to compression depending on their content. Photographs with smooth gradients compress well; images with sharp text or flat colour regions show artefacts sooner and are often better served by resizing or a format change.
