Why compress images?
Heavy images slow your site down and hurt rankings. Compression removes data the eye barely notices, often cutting file size by more than half. Faster pages mean better Core Web Vitals, lower bounce rates, and happier visitors — and it all happens privately in your browser here.
Frequently asked questions
How much smaller will my image get?
It depends on the image and the quality you choose, but JPG/WebP compression commonly cuts file size by 50–80% with little visible difference. The live comparison shows the exact saving.
Does compressing reduce quality?
Slightly, and you control how much with the quality slider. Around 70–85% is the sweet spot for photos — much smaller files, hard to tell apart from the original.
Is my image uploaded anywhere?
No. Compression happens entirely in your browser. Your file never leaves your device, so it is completely private.
Should I use WebP?
WebP usually produces smaller files than JPG at the same quality and is supported by all modern browsers. Switch the format to WebP for the best compression.
