Compress Image to 500KB

Automatically tunes quality until your JPG, PNG, or WebP fits under 500KB - free and entirely in your browser.

500KB is a practical upper bound for hero images and full-width banners - large enough to keep a 1920px-wide photo looking crisp, small enough not to wreck your page's load time. If your hero currently weighs several megabytes, compressing to 500KB is often the biggest single performance win available. Pair it with WebP output in the advanced controls for even better results.

Frequently asked questions

Is 500KB small enough for good page speed?

For a single above-the-fold hero, yes - it's a widely used budget. If the page carries many large images, aim lower (100-200KB each) or lazy-load everything below the fold.

Why not compress the hero even further?

You can, but large images show artifacts sooner. 500KB at 1920px wide is usually the balance point; test 200-300KB versions if your audience is mobile-heavy.
