Le Monde has reported that 1 million copies of Charlie Hebdo will be published on Wednesday.
The Guardian Media Group has now offered £100,000.
According to The Guardian, the average weekly circulation for Charlie Hebdo is about 45,000. The update was announced by Richard Malka, the satirical newspaper's lawyer.
Columnist Patrick Pelloux told local media: "It's very hard. We are all suffering, with grief, with fear, but we will do it anyway because stupidity will not win." He said the remaining team would meet soon.
Martin Rowson, the chairman of the British Cartoonists' Association, called on his colleagues to donate free cartoons. He wrote in the Guardian:
Charlie Hebdo is planning to continue printing its magazine next week. As chairman of the British Cartoonists' Association, I am calling on my fellow cartoonists to join me in donating a free drawing. We should support them materially. We must also make a statement.
After it was firebombed in 2011, Charlie Hebdo published this cover. Its caption says "Love is stronger than hate".
Vigils were held around the world last night for the victims of Wednesday's attack at the publication's offices.
Twelve people died in the shooting. Two of the three suspected assailants remain at large.
