Why compress images?
Smaller images load faster, improve SEO rankings, and reduce bandwidth costs. Most photos compress 50–95% with little visible quality loss at moderate quality settings.

Frequently asked questions
Does compressing an image reduce its quality?
Lossy compression removes data the human eye barely notices. At sensible settings (70–85% quality for JPG) most photos look identical while shrinking 60–80% in file size.
Are my images uploaded to a server?
No. The entire compression runs in your browser using JavaScript. Your files never leave your device, which also means there is no file size queue or privacy risk.
What is the best image size for a website?
For most web pages, keep images under 200 KB and no wider than the layout needs (typically 1200–1600px). Smaller files improve page speed, which is also a Google ranking factor.
Should I use JPG, PNG or WebP?
JPG suits photos, PNG suits graphics that need transparency, and WebP usually beats both in size at the same quality. If your platform supports WebP, it is the best default for the web.
