When do you need a file under 500KB?

500KB keeps photos sharp while meeting upload limits on forms, CMS platforms and email newsletters.

How It Works

The tool searches for the highest quality setting that still fits under 500KB. Only if even the lowest quality is too large does it gently reduce the pixel dimensions. PNG is lossless, so PNG files are made smaller by resizing only.

Frequently asked questions

Is compressing to 500KB free?
Yes — free, no sign-up and no watermark.
Are my files uploaded?
No. Compression runs in your browser, so your files stay on your device the whole time.
What if my file can't reach 500KB?
You'll get the smallest version that could be made and a notice that it's still above the target. You can then pick a larger target or trim the file first.
Can I choose a different size?
Yes. 500KB is only the default — type any target size before clicking Compress.
