Instagram will help teenagers to wipe their accounts of old posts as they grow up and "fully understand information they've shared", its boss has said.

       Adam Mosseri said users would soon be able to bulk delete old posts to help them "manage their digital footprint". The move comes as Instagram announced a series of other changes to make it safer for children and give parents more control over their usage of the app.

       In a blogpost on Tuesday, Mr Mosseri said Instagram was building a new feature for release next year that would allow users to see all their posts and the comments they have made on other people's profiles in one place and remove them.

       He wrote: "We know that, as teens grow up, they want more control over how they show up both online and offline so, for the first time, they will be able to bulk delete content they've posted, like photos and videos, as well as their previous likes and comments.

       "While available to everyone, I think this tool is particularly important for teens to more fully understand what information they've shared on Instagram, what is visible to others, and to have an easier way to manage their digital footprint."

       As well as the new safety features, Instagram also released more details of parental controls it is building into the app, which has a minimum age of 13. From March, parents will be able to see how much time their children are spending on Instagram and set time limits for them.

       The changes come as the social network and other tech giants face stricter rules around child privacy and online harm that could see them hit with fines running into the billions.

       Earlier this year, the UK's privacy watchdog, the Information Commissioner, was handed new powers to fine tech companies found to be using the private information of under-18s to target them with harmful features.

       The Government is also currently drawing up duty of care laws, for which The Telegraph has campaigned since 2018, which threaten tech companies with huge fines or even being banned from the UK if they allow children to come to harm on their services.
