Image Compressor for Websites

How to compress an image without losing quality

Most of the saving doesn't come from the quality setting. It comes from two simpler things:

1. Resize to the size it's shown at. A 4000-pixel photo shown 1200 pixels wide carries about 11 times more pixels than needed. Pick a maximum width and the file shrinks dramatically.
2. Use an efficient format. Switching "Convert to" from "Same as original" to WebP usually saves far more than lowering quality.

Then use quality 75 to 85 for photos. At those settings the difference is very hard to see, but the file is much smaller.

What size should website images be?

There's no single rule, but these are good targets for small business websites:

• Full-width banners: under about 300 KB
• Content and blog images: under about 150 KB
• Thumbnails and logos: under about 50 KB

Images that are much larger than this are one of the most common reasons we find for slow small business websites, especially on mobile data.

Why didn't my PNG get smaller?

PNG is lossless, so re-saving it as PNG can't throw away detail. If a compressed version would be bigger, the tool keeps your original file. To make a PNG much smaller, convert it to WebP, which still supports transparency, or resize it.

Is it safe for private photos?

Yes. Images are compressed inside your browser and never uploaded. Hidden metadata such as GPS location is removed from the compressed files.

Does compressing images help SEO?

Faster pages give visitors a better experience, and page experience is something Google considers. Compressed images won't rank a page on their own, but slow, heavy pages make everything else harder. Our SEO health checklist covers the other basics.
