Open the Developer console in your browser of choice.atob() function translates into ASCII to binary and btoa() means binary to ASCII. ![]() The name of these functions represents their utility. To encode and decode data with Base64, you can take advantage of the two helper functions atob() and btoa() in Javascript. How to Encode Data with Base64 in Javascript The new charging sound can be Base 64-encoded to ASCII using the Shortcuts app on Apple’s mobile devices. Otherwise if some network packets happen to get lost during the transfer, the data inside the file may become corrupted and your file will be no longer usable.Īnother very popular but rather niche use for Base64 encoding is setting a custom iPhone charging sound. ![]() If you are transferring a big BLOB (Binary Large Object File) across the internet, it’s actually mandatory to encode the data using Base64. The base64 package ships with GNU Coreutils, which is installed on most Linux distros. Otherwise it will result into very big file sizes and slow down the website (alternatively, you can use webp file format to compress the image). On Linux, we have access to the base64 utility, which can encode and decode a file and display it on the standard output. You’ll need make sure to compress the image before encoding, though. This technique can help reduce the number of requests from clients and make your website more performant. With Base64, encoded images can directly be added to HTML documents or in CSS files. ![]()
