An ARW file is a graphics file format created and used in conjunction with Sony cameras and allows highly detailed images to be stored in a compact digital file format with far greater definition compared to other image formats such as JPG.

The highly specialised nature of the ARW file format means that editing it requires specialist software, though they can be viewed on some operating systems natively, such as Windows 11.

A WebP file is a next-generation image file format designed for the web. It allows large and highly detailed photographic-quality images to be stored using a very small file size, making it an ideal format for use by websites where bandwidth comes at a premium.

It's aim is to replace other photographic formats, such as JPEG, by offering similar levels of compression and quality while offering a superior reduction in file size. As well as storing static images, the WEBP format can also store animations, making it a great alternative to the traditional animated GIF format.

As the WEBP format is still relatively new, support for it is best found in modern image editing applications or those that benefit from regular updates.
