Compress an Image

Shrink a JPG, PNG or WEBP with an adjustable quality slider.

Make photos and graphics lighter for the web or email. Adjust a single quality slider to trade a little detail for a much smaller file, and preview the size before you download.

Compression happens on your device, so your images never leave the browser.

How to compress an image

  1. Add a JPG, PNG or WEBP image.
  2. Move the quality slider to your preferred balance.
  3. Download the compressed image.

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.
