The new Independent website is to begin with an editorial staff of around 75.
Some 50 journalists already work on the site and around 25 are expected to transfer across from the newspaper.
Digital editor Christian Broughton continues, so will effectively be editor of The Independent. Current Independent newspaper editor Amol Rajan will be editor at large.
Press Gazette understands that foreign correspondents Patrick Cockburn and Robert Fisk are among those staying on.
Ollie Wright will continue as political editor, Rupert Cornwell is to continue reporting from Washington, Simon Calder is set to continue as travel editor and Grace Dent is among a number of newspaper columnists who will continue writing for the site.
The New York office, which currently has seven staff, is set to double in size.
Correspondents are set to be appointed for Beirut, Hong Kong and Paris.
The i100 website is going to stay with The Independent and become the Indy100.com.
Broughton has told staff that he wants to ensure the Independent.co.uk “embodies the qualities that made the print editions stand out”.
He said in an email to colleagues: "The most frequently asked questions concern whether our core values and our most widely celebrated journalists will continue. To answer both these questions, I want to offer reassurance that many of the writers the world expects to see in the Independent will be a part of our digital future."
In December, The Independent attracted some 2.8m unique browsers per day and 59m over the course of the month, according to ABC. Some 21.4m unique browsers per month come to The Independent from the UK, with the rest coming from around the world.
The Independent has launched a paid-for app aimed at tablet computers called the Daily Edition. It aims to replicate a newspaper-style reading experience and costs £2.99 a week.
