Compress an image to 300KB

300 KB is the comfortable middle: more headroom than a 200 KB web target, lighter than half a megabyte. It suits blog images, forum attachments, and upload forms that give you a bit of slack. Add your photo and it's compressed to land at or under 300 KB with as much detail as possible — all in your browser, nothing uploaded.

Images are compressed to at or under your target, and never leave your device.

Questions

How do I compress an image to 300KB?
Add your image, and the tool trims it until it's at or under 300 KB, then download it. Most photos reach 300 KB with quality alone, without needing to shrink the picture.
Is 300KB too big for a web page?
It's fine for one main image on a page, but it adds up quickly if you use several. Drop to 100 or 200 KB for photos further down the page, and keep 300 KB for the one that matters most.
Does my image leave my device?
No. Compression happens in your browser, so the image is never uploaded or stored anywhere.
