Then, add the domain to your netlify.toml file: Īutomatic integrations are coming soon for most frameworks, so you won’t need to think about them at all in the near future, but you can use them with all the major frameworks today if you use a library like Unpic. To use a remote image, pass in the complete URL: This will resize the image “/owl.jpg” to fit within an 800px x 600px box, and automatically deliver the best format. It works out-of-the-box for all of your local images and the transformation options are passed as regular query params. Mistakes can undo all of your hard work, so we wanted to make this feel as simple and accessible to developers as we could, which is why we’ve given Netlify Image CDN the simplest possible API.

Modern browsers support several advanced new formats that offer dramatically better quality and compression level, which means developers can maintain image quality but dramatically decrease the size of the file to optimize for web performance.īrowser support is good, but not universal. While JPEG and PNG files have served us well, we can do so much better with newer technologies. ![]() Next, we decided to address image format. We’ve all seen those sites that accidentally use a multi-megapixel image for a thumbnail, which is why we’ve now made it dead simple to resize your images, with the added functionality of lots more options for how you want to crop and resize them so they look just right. ![]() There are, however, a few actions that every site needs.Īt the top of the list is resizing and cropping – nothing affects performance more than unnecessarily large images being loaded onto a webpage.
