Frequently asked questions

Why compress images?

Images are usually the heaviest part of a web page. Smaller images load faster, which improves user experience, Core Web Vitals and conversion, especially on mobile networks.

What is WebP?

WebP is a modern image format that is typically much smaller than JPEG or PNG at similar visual quality, and it is supported by all current browsers.

What quality should I choose?

Around 75 to 85 percent usually looks identical to the eye while cutting file size a lot. Lower it for large background images, raise it for detailed product photos.

What size should website images be?

Match the largest size the image is displayed at, with some allowance for high-density screens. A full-width hero rarely needs more than 1600 to 2000 pixels.

Are my images uploaded?

No. Compression runs in your browser using a canvas, and the files never leave your device.
