Since Base64 encoded data is approximately 33% larger than original data, it is recommended to use Base64 data URIs only if the server supports HTTP compression or embedded files are smaller than 1KB. The data, separated from the preceding part by a comma (,). The data is a sequence of zero or more octets represented as characters. The comma is ...
Because Base64 is a six-bit encoding, and because the decoded values are divided into 8-bit octets, every four characters of Base64-encoded text (4 sextets = 4 × 6 = 24 bits) represents three octets of unencoded text or data (3 octets = 3 × 8 = 24 bits). This means that when the length of the unencoded input is not a multiple of three, the ...

Using XOP avoids this by extracting the binary data out of the XML Infoset so that the XML Infoset does not contain binary data and the binary data can be serialized differently. Therefore, XOP can reduce the size of the serialization (since base64 encoding has approximately a 33% size overhead) and (depending on how it is implemented) might ...
The Extensible Metadata Platform (XMP) is an ISO standard, originally created by Adobe Systems Inc., for the creation, processing and interchange of standardized and custom metadata for digital documents and data sets. XMP standardizes a data model, a serialization format and core properties for the definition and processing of extensible metadata.

Xena attempts to avoid digital obsolescence by converting files into an openly specified format, such as ODF or PNG.If the file format is not supported or the Binary Normalisation option is selected, Xena will perform ASCII Base64 encoding on binary files and wrap the output in XML metadata.
XnView can read more than 500 image file formats, some audio and video file formats, and write 50 image file formats. [13] XnView also supports ICC profiles in JPEG , PNG and TIFF files. It doesn't respect loop settings on animated files, however, and will infinitely loop them, regardless. [ 14 ]
