asantoolCompress or convert to WebP
WebP is the most efficient format a browser can write today — typically 25 to 35% smaller than a JPG of the same visual quality, and unlike JPG it keeps transparency. Every current browser supports it.

Common questions
Should I use WebP instead of JPG?
For anything on a website, yes — it is smaller at the same quality and every current browser reads it. The exception is a file you need to hand to someone else, where JPG remains the format every piece of software on earth opens without question.
Can I convert a PNG to WebP and keep transparency?
Yes. WebP supports transparency, so a logo or cutout converts cleanly and usually lands far smaller than the PNG did.
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.
