How to Compress Images Online
Large images slow down websites, eat storage, and use up bandwidth. Compressing an image reduces file size while keeping it looking good. This guide explains the basics of online compression and shows how to get the best results fast.

Open a free compressor like Pixcutly's Compress page.
Upload one or more images at once (batch compression supported).

Download the optimized images — Pixcutly keeps everything in your browser.
Pro tip
Start with a target size or quality around 80% and eyeball the result. You can usually cut file size by over half with no visible difference.
