Resize, compress and convert images to JPG, PNG or WebP.
The image resizer changes the dimensions of an image, compresses it and converts it to JPG, PNG or WebP. Enter a width or a height to keep the proportions, or both to set an exact size, and choose the quality.
Images are the heaviest part of most web pages. Resizing them to the size they're shown at and saving them as WebP can cut their weight by 70% or more, which speeds up the page and improves Core Web Vitals.
Keep the aspect ratio or set an exact size.
Choose the JPG or WebP quality.

In PNG and WebP, yes. JPG has no transparency, so a white background is added.
