Heavy images are the #1 cause of slow websites. Compressing them well improves load speed, user experience and Core Web Vitals (which affect SEO). Here is how to do it with no visible loss.
How to compress an image step by step
- Open the compress image tool.
- Upload your JPG, PNG or WebP.
- Adjust the compression level and download.
Free, in batches and in your browser: your images are never uploaded to a server.
Lossy or lossless: which to choose
- Lossy (JPG, WebP): cuts size a lot by discarding barely visible data. Ideal for photos.
- Lossless (PNG): keeps every pixel but compresses less. Ideal for graphics and logos.
Why it matters for your site and SEO
Google measures speed with Core Web Vitals (especially LCP, which is often an image). Lighter images = faster load = better ranking and less bounce.
Combine with modern formats
To maximize savings, also convert to WebP or AVIF: much lighter than JPG at the same quality. And if the image is bigger than needed, resize it before compressing.
