Compress an image to 500 KB

Bring a photo under 500 KB without leaving the page. Roomy enough for a good-looking photo, and the usual cap on CV attachments and CMS uploads. The tool below opens already set to that limit — add your image and it finds the best quality that fits.

Questions

Common questions

Is 500 KB small enough for a web page?

For a full-width hero image, yes. For anything smaller on the page you can usually go much further — most photos on a website are fine between 100 and 200 KB once they're sized to the space they occupy.

How do I compress an image to 500 KB?

Add your image to the tool on this page. It is already set to a 500 KB target, so it will search for the highest quality that lands under that size and show you the result next to the original. Then download it.

Is my image uploaded anywhere?

No. The work happens in your browser using image APIs it already ships with, so the file never leaves your device. There is no upload to wait for and nothing stored on a server afterwards.
