How to use it

  1. 1

    Throw in your photos: JPG, PNG or WebP, a dozen at a time if you like.

  2. 2

    Pick a mode. In quality mode you move the slider yourself; in size mode you just say how many kilobytes the file should weigh.

  3. 3

    Hit “Process”. Under each file you will see what it weighed and what it weighs now.

Common questions

How do I compress a photo to 200 KB?

Switch to size mode and type 200. The quality is worked out for you: a binary search walks the values until the file fits.

Is it really lossless?

For PNG, yes — the pixels stay untouched and only the file gets squeezed. JPG always loses something, but at 80–85% you cannot see it, and the file ends up several times lighter.

What quality should I use?

Start at 80% for photos. Below 60% you start seeing blocks in skies, gradients and around lettering.

How big a file can I put in?

Up to 100 MB on a computer, up to 25 MB on a phone. The limit is really about how much memory the browser will hand over.
