While most people prefer to use a specific webpage as the home page in their web browser, others have chosen to use about:blank instead. Is about:blank simply a blank webpage or does it have a special purpose? Today’s SuperUser Q&A post has the answers to a curious reader’s questions.
Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites.
SuperUser reader “Guy named Jon” wants to know what the about:blank page in web browsers is for:
What is the about:blank page in a web browser used for? I was just wondering why it is there. Is it an actual webpage or just something that is built in? It seems to be completely empty except for the header and body.
What is the about:blank page in web browsers for?
SuperUser contributors Keltari and bwDraco have the answer for us. First up, Keltari:
It is simply a blank page that is built into some web browsers. Some people just like to have a blank page rather than see/load anything else when they start their web browser or open a new tab/page.
Followed by the answer from bwDraco:
Per IETF RFC 6694, about:blank is reserved for a blank page. Essentially, every web browser that supports about implements about:blank and it is pretty much the same everywhere.
Because about:blank is little more than a blank internal page, it does not depend on any external resources and serves as a good default on metered connections or slow systems.
