Compress a PNG to 500 KB

Design exports and full-screen screenshots saved as PNG are often 3 to 10 MB. As a JPEG under 500 KB they look nearly identical.

Getting a PNG under 500 KB

A design export or a high-resolution screenshot saved as PNG is often 3 to 10 MB, because PNG never throws detail away. Converted to a high-quality JPEG, the same image usually drops under 500 KB with no difference you can see at normal size.

We keep as many pixels and as much quality as the limit allows, starting at 4000 pixels on the longest side and quality 92. Transparent areas become white.

Tips

  • Sharp text and thin lines, as in screenshots, show JPEG artifacts first. Zoom in on small text in the result before you upload it.
  • If you control the export, a JPEG export straight from your design tool is often smaller still.
  • Images with large flat areas of one color, like diagrams, shrink the most.

How it works

  1. 1

    Drop your file

    A PDF or an image. It goes over an encrypted connection and nowhere else.

  2. 2

    Pick your limit

    Choose the size the form asks for. We start with a cleanup that changes nothing you can see.

  3. 3

    Download it

    If it needs more, we find the gentlest quality setting that still fits, and delete everything soon after.

Questions

Is it free?

Yes. There is no sign-up and no watermark.

What happens to my file?

It is processed on our server and deleted automatically: the original 5 minutes after the run finishes, the compressed file after 10. A file you upload but never compress is deleted within 30 minutes. You can also delete everything right away with Delete now.

Will it look worse?

We try a lossless cleanup first, which does not change how the file looks. Only if that is not enough do we lower image quality, and we pick the gentlest setting that still fits your size.

What if my file cannot get that small?

You get the smallest version we could make and a clear note saying so, instead of a file that silently misses the limit.

Why does the size page aim a little under its limit?

Some sites count a kilobyte as 1000 bytes and others as 1024. We aim under the stricter one, so a 200 KB page aims for 200,000 bytes and the file passes either way.
