Frequently asked questions
Which formats can I compress?
JPG, PNG and WEBP are all supported, with a quality slider that lets you control the final size.
Will compressing ruin the image?
At moderate settings the difference is barely noticeable. Push the slider lower only when small size matters more than fine detail.
