Frequently asked questions
Why compress website images to 500 KB or less?
Smaller images make pages load faster, especially on phones. For extra savings on a website, choose WebP as the output format.
Will 500 KB reduce quality?
Usually very little. Most photos can be compressed to 500 KB with no visible difference at normal viewing size.
Should I resize as well?
If the photo is wider than about 2000 pixels, set a maximum width too. It keeps the photo sharper at the same file size.
Are my files uploaded to a server?
No. Compress Image to 500 KB runs entirely in your browser, so your files stay on your device. Nothing is uploaded, stored or seen by anyone else.
Is Compress Image to 500 KB free?
