"One image can be worth a thousand words". Images are a great way to improve your blog posts and make them more appealing and informative to your users. However, images can also be a source of performance issues if not used properly. Hyvor Blogs automatically optimizes images for you when possible.

WebP Format

WebP images are 25-34% smaller than JPEG/PNG images of the same quality. It is recommended nowadays to use WebP in websites whenever possible as all modern browsers support WebP images. You can upload JPEG and PNG as usual in your posts. Hyvor Blogs will serve them in WebP format to your users via /media of your blog. You don't have to do anything.

Note that the extension in the URL will not change (ex: /media/image.jpg or /media/image.png), but the image will be served as WebP with correct HTTP headers. You can verify this by checking your page in PageSpeed Insights.

Responsive Images

Hyvor Blogs handles responsive images for you. Here's how it works.

Images (PNG, JPEG, WebP only) uploaded to /media can be automatically resized by appending /{width}w to the URL.

We use this resizing feature and srcset (supported by all modern browsers) to make images in your posts responsive. These are the sizes we use:

For example, if you upload a 1250px image to a post, the HTML code would look like this:

        /media/image.jpg/500w 500w, 
        /media/image.jpg/750w 750w, 
        /media/image.jpg/1000w 1000w,
        /media/image.jpg 1250w

Then, the browser will decide the best image version to load based on the screen size and the device pixel ratio (DPR).

Note that responsive images are not supported for externally hosted images (ex: images from Unsplash)
