{{Short description|Web page in-line data scheme}}
{{Lowercase title}}The '''data URI scheme''' is a [[Uniform resource identifier|uniform resource identifier (URI)]] scheme that provides a way to include data in-line in [[Web page]]s as if they were external resources.  It is a form of file literal or [[here document]]. This technique allows normally separate elements such as images and style sheets to be fetched in a single [[Hypertext Transfer Protocol|Hypertext Transfer Protocol (HTTP)]] request, which may be more efficient than multiple HTTP requests,<ref>{{cite web|url=http://blog.teamtreehouse.com/using-data-uris-speed-website|title=Using Data URIs to Speed Up Your Website|date=27 March 2014|publisher=Treehouse Blog}}</ref> and used by several browser extensions to package images as well as other multimedia content in a single HTML file for page saving.<ref>{{cite web|url=https://chrome.google.com/webstore/detail/singlefile/mpiodijhokgodhhofbcjdecpffjipkle|title=SingleFile - Chrome Web Store|website=Chrome Web Store|access-date=25 August 2018}}</ref><ref>{{cite web|url=https://addons.mozilla.org/en-US/firefox/addon/single-file/|title=SingleFile – Add-ons for Firefox|website=Firefox Add-ons|access-date=25 August 2018}}</ref> {{As of|2024}}, data URIs are fully supported by all major browsers.<ref>{{cite web|url=http://caniuse.com/#feat=datauri|title=Can I use...|first=Alexis|last=Deveria|date=July 2015|access-date=31 August 2015}}</ref>
