Image Compressor — Compress Images Online Free

Need to compress an image online for free? This tool shrinks a photo to a smaller file size right in your browser, with a quality slider that lets you control exactly how much you compress - and nothing is uploaded. Smaller images load faster, attach to emails more easily, and take up less storage.

Want a smaller file without guessing the outcome? Drag the quality slider to find the sweet spot between file size and clarity, and use the before/after size comparison to see exactly how much smaller your image becomes before you commit. You stay fully in control of the trade-off, so you can push for the smallest possible file or hold on to more detail, depending on what the photo is for.

You can save the compressed result as a JPG, WebP, or PNG, so you can pick the format that fits your needs - a smaller lossy file for sharing and faster web pages, a modern WebP for an efficient balance, or a PNG when you want to keep transparency and crisp edges. Matching the format to the job helps you get the smallest file without sacrificing what matters in the image.

Because the compression runs 100% in your browser, your photos never leave your device and nothing is uploaded to a server. That keeps your images private and makes compressing fast, even when you have several files to get through one after another, with no waiting on uploads or downloads from the cloud. It is a simple, reliable way to lighten your photos for the web, for email, or for storage while keeping full control over how they look.
