The performance, in front of 20,500 fans, was filmed live in Manchester on Friday, and saw the 32-year-old perform his fourth studio album - Kiss All The Time, Disco, Occasionally - in full on the day of its release, before finishing with an encore of older tracks including some of his biggest hits.
"This is not the tour show, we don't ever play it like this again," Styles said in a trailer for the concert.
Styles has played One Night Only shows to celebrate the release of each of his previous albums, and the show comes ahead of his Together, Together tour, which will include 12 nights at Wembley Stadium, potentially breaking the record for most show by any artist in a year at the national stadium in London.
The global tour, beginning in May, will also see Styles perform in Amsterdam, New York, Sao Paulo, Mexico City, Melbourne and Sydney.
"I've kind of rediscovered what a privilege it is to be in people's lives through music over the last couple of years," Styles told fans during the Manchester show.
"You've changed my life. Thank you so, so much.
"Thank you for the warmth and generosity you've always given towards me over the last one, two, five, 10, 15 years of my life."
The concert was the first of its kind for the singer since the death of former bandmate Liam Payne, who fell from a hotel balcony in Argentina in October 2024.
Styles praised his fans for creating communities with hope in a world "that feels so chaotic it is so easy to become hopeless".
"The world could do with a little extra peace right now so please do all you can," he said.
Fans' phones were put into bags preventing them from filming and they were handed disposable cameras as they arrived at the arena, which Styles invested in ahead of its opening in 2024.
The pop star, who grew up in nearby Cheshire, also gave 100 tickets to students from Holmes Chapel Comprehensive School, where he was a pupil when he applied for The X Factor in 2010.
Others were able to earn their tickets by volunteering at community projects in Manchester.
Styles was accompanied by a band and gospel choir as he broke into dance moves during the song, which he had performed in the same venue at last week's Brit Awards.
The show's encore saw the star perform Golden, which he played on the guitar, and Watermelon Sugar saw an ecstatic crowd dancing and singing along before the night's biggest crowd pleaser, number one single As It Was.
The show's release comes after Styles made a cameo appearance on Saturday Night Live, sitting in the front row as actor and guest host Ryan Gosling delivered his opening monologue at the start of the US sketch show on Saturday.
