Downscale Image

Downscale Image is an easy-to-use online tool for shrinking photos and screenshots down to a smaller file size—whether you need a quick compression, an exact file size in KB, or full manual control over resolution and quality.

Smaller images load faster on websites, attach more easily to emails and forms, and take up less space on your device. Many upload forms even enforce a maximum file size, and this tool makes it simple to fit under the limit.

Drag the quality slider for a quick tradeoff, switch to an exact file-size target like 100 KB, or set a maximum width and height and crop the image yourself — all with a live before/after preview.

All image processing happens locally in your browser, so your images never leave your device—making Downscale Image a great option for privacy-conscious users working with personal photos or sensitive documents.

We also have a Compress Image Android app that lets you compress images on the go. Our app supports batch processing, so you can shrink multiple images at once effortlessly.

All processing happens locally in your browser—your images never leave your device, keeping your data private and secure.
