DDD (Snappy -> SVG) is a Chrome extension developed by manu.dev that falls under the Browsers category, specifically in Add-ons & Tools. This free extension allows users to decode Base64, decompress Snappy, and download SVG files effortlessly. To utilize the extension, users need to enable access to file URLs in the Chrome extension options. Once enabled, users can open a file that is compressed using Snappy and encoded in Base64. By clicking on the extension icon, users can easily download the original uncompressed file.

The extension is currently equipped to handle Snappy compression, but future updates promise support for zlib compression types. Additionally, the developer plans to enhance the extension's functionality to allow for the customization of downloaded file formats beyond just SVG.
