Optimization without noticeable quality loss

Image size has a direct effect on page load speed, and faster loading means fewer visitors bouncing and better search rankings. The tool lets you reduce the "weight" of an image by adjusting the compression quality with a slider: you instantly see the resulting file size, the percentage saved, and a preview next to the original so you can judge whether the picture still looks right.

The key feature of the service is that all processing happens directly in the browser, with no file sent to a server. That means compression takes a fraction of a second regardless of the source file size, and the image itself is never transmitted or stored on the site - which matters if you are working with personal photos or images containing sensitive information.

The tool comes in handy when preparing images for a blog post, product cards in an online store, social media posts, or attachments for emails and services that often limit file size. By moving the slider left or right, you can quickly find the right balance between file weight and visual quality for the task at hand, then download the result right away.
