This tools converts an image to Base 64 Data Encodings specification (RFC 4648). Base64 is a group of schemes that encode binary to text. This represents binary data in an ASCII strong format. Translation is done via radix 64.
The data URI provides a way to include your image in-line in web pages as if they were external resources. You can embed the image data directly into the document with data URIs.
data:[<mime type>][;charset=<charset>][;base64],<encoded data>
Embedded images should be stored in cacheable files such as flat, not dynamic, HTML and style sheets. Data URI style sheets should be cached long term, rename the file on each update.
The file size increases by approximately 30% which may be offset by serving as part of a compressed (gzip / deflate) file.
<img src="data:image/gif;base64,data:image/gif;base64,R0lGODlhAQABAIABAP///wAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==" />
To use image as a link in HTML, use the <img> and embedd the <a> tag with the href attribute. These html tags can be used for specific reason
Within the image tag src attribute, include the URL of the image and specify the height and width to limit the size.
First of all, let's read the file content to a byte array and use Java 8 Base64 class to encode it:
byte fileContent = FileUtils.readFileToByteArray(new File(filePath)); String encodedString = Base64.getEncoder().encodeToString(fileContent);
The encodedString is a String of characters in the set of A-Za-z0-9+/, and the decoder rejects any characters outside of this set.
Now we have a Base64 String, let’s decode it back to binary content and write to a new file:
byte decodedBytes = Base64.getDecoder().decode(encodedString); FileUtils.writeByteArrayToFile(new File(outputFileName), decodedBytes);
You can use base64_encode() to encode strings as base64.
base64_encode( $string ) will return a string that contains the encoded version of the given string. The function takes an optional argument that specifies how many characters should be used for encoding.
This function encodes binary data into an ASCII string format.
If you need to convert binary data into an ASCII representation, then base64_encode($binaryData) is what you need. It returns a string containing the encoded version of the binary data.
This function will convert any string into a valid base64 encoded string.
To decode a base64 encoded string, you can use base64_decode(). It takes a string as input and returns the original binary data.
