Base64-encoded data takes about 33% more space than the original data. This encoding is designed to make binary data survive transport through transport layers that are not 8-bit clean, such as mail bodies. The PHP provides base64_encode and base64_decode. The Base64 can be easily implemented by modern programming language in many many ways, e.g.
Web base64 encoding code#
If images get updated, you have to re-obtain the Base64 code.You are increasing the size of images by 133%.Prevent image 404 errors due to invalid directory, permissions etc.Reduce the number of HTTP/HTTPS requests.If the file is of type image, then you can inline the images using the following two methods:Ĭopy to CSS background-image: url("data:image/png base64,iVBORw0KGgo=.") Choose a file locally and wait for a few seconds before the browser encodes the binary data into BASE64. HTML5 provides a local file reader object that allows you to load files locally without sending to the server.

Extra '=' are padded into the input so that last group always has 4 base64 digits.Įxample: This page provides a Javascript online web-based Base64 Encoder/Decoder. that is only 1 or 2 characters at the end of the input, then the following action is performed: Extra bytes are added with value zero so there are 3 bytes, and perform the conversion to base64. If the length of the input is not divisible by 3, i.e. Thus, each new character is from 0 to 63, which is mapped into new characters using this 64-character table.
3 X 8 = 24 bits, and regroup it into 4 characters 4 X 6 = 24 bits. It uses a 64 character table ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789+/= and group every 3 characters of input, e.g. The Base64 Encode Technique is often used to make binary data (those non-printable) into text-printable characters. This page provides a Javascript implementation online Base64 encoder and decoder that can be used to convert Text and Binary Data to Base64 format.
