Compress images and cut file size — securely in your browser
Our Image Compressor makes JPG, PNG, and WebP files dramatically smaller without sending a single byte to a server. It re-encodes your picture at a quality level you control, discarding the fine detail that the human eye barely registers while keeping the parts that matter looking crisp. Because everything runs on an in-browser canvas, even sensitive images stay private on your device throughout.
Large images are the number-one cause of slow-loading web pages, sluggish email attachments, and storage that fills up faster than expected. Compressing them fixes all three at once. A live before-and-after readout shows the original size, the compressed size, and the percentage saved, so you can dial in exactly the trade-off you want between file size and image quality before downloading.
The tool is built for real-world workflows. Web developers and bloggers use it to hit Core Web Vitals targets and speed up their sites, online sellers shrink product photos for faster catalogs, and everyday users squeeze pictures under the attachment limits of email and chat. Switching the output to WebP often halves the size again compared with JPG, and a lossless PNG mode is there when transparency and exact fidelity are non-negotiable.
