Compress image

Shrink JPG, PNG or WEBP photos right in your browser — pick a quality, or a target size in KB and the real encoded bytes are measured until it fits. Transparent PNG areas become white when saving as JPG; choose WEBP to keep transparency.

This tool runs entirely in your browser — nothing you type or open here is ever uploaded. You can disconnect from the internet after the page loads and it still works.
