Are New Image Formats Worth It for You?

In the wise words of a certain content creator: If it's not worth it, don't do it! Easily learn if you would really benefit from adding modern image formats like WebP, AVIF, and JPEG-XL to your website with this tool. Numbers for support are pulled from Caniuse ("full support") and may change in the future. Default BD-rate savings values are estimates, based on the use of MozJPEG to encode the JPEG, and are probably wrong, but you get the idea.

We want the number of page views needed for you to break even by adding a new format with the JPEG as a fallback. The formula is generally:
SBCR * ((1 - savings) / (savings * support))
where:

• SBCR (storage-to-bandwidth cost ratio) is the ratio of how much it costs to store an image vs how much it costs to serve the image.
• Savings is the BD-rate savings of the new format vs JPEG, expressed as a number from 0.0-1.0.
• Support is the fraction of browsers that support the new format, expressed as a number from 0.0-1.0.

Generally, a very high SBCR means adding formats to the fallback chain is less desirable. More savings will make the format more desirable, as will more support. Enter some information below and we'll help you get all those values.

Calculate your SBCR:

Server storage capacity:

GiB

Server monthly bandwidth cap:

Your SBCR:

Or perhaps you might have UNMETERED bandwidth: 250 Mbps 500 Mbps 1 Gbps 2.5 Gbps 10 Gbps

Unmetered bandwidth isn't truly unlimited, you only have a month to use what you paid for. Click the buttons to calculate that for you.
