Writing and production
Originally titled as "What Doesn't Kill You", "Stronger (What Doesn't Kill You)" was written by Jörgen Elofsson, Ali Tamposi, David Gamson, and Greg Kurstin in September 2010. In an interview with American Songwriter, Tamposi revealed that the song was inspired by the Friedrich Nietzsche adage ("That which does not kill us makes us stronger") that her mother told her as advice. Although Tamposi found the phrase saccharine, she submitted it as an idea to Elofsson and Gamson during their writing sessions. Elofsson originally intended "Stronger" for Leona Lewis, who turned it down in the process. Tamposi's manager, Tom Maffei, then had one of his producers, Matty Trump, produce a demo track, later pitched to RCA A&R executive Jeff Aldrich, who gave the song to Clarkson. Tamposi revealed that Clarkson had also altered a lyric from the track. Aldrich had then commissioned Greg Kurstin, whom Clarkson wanted to collaborate with, to produce and add additional writing to the final version. Kurstin recalled, "I rethought the music part of it, I guess. It had a different tempo, beat, chords, and I kinda just came up with that guitar riff that goes into the verse, and that was the first thing that I kinda contributed just changed the feel of the song." The song's uplifting theme of empowerment led Clarkson to name her fifth studio album Stronger. Saying that it is one of her favorite songs in the album, she said, "Everybody loves the message 'What doesn't kill you makes you stronger.' It's a perfect representation of my life."

Release and reception
After returning from a vacation in Tahiti, Clarkson found out over 50 of her newly recorded demo material were leaked online, including "Stronger". She commented that the leak felt worse than being physically robbed. In an attempt to counter-attack the leakage, RCA finally debuted the song online on October 5, 2011, three weeks ahead of the album's release. An acoustic version of the song appears in Clarkson's second extended play, iTunes Session. The song was featured in a Toyota Camry commercial featuring Clarkson and other celebrities. "Stronger" was officially released as the album's second single to mainstream radio on January 17, 2012. A dance remixes of the song were made available on February 3, 2012. On February 17, 2012, it was released as a CD single. Critical response Jenna Hally Rubenstein of MTV Buzzworthy compared it to "Since U Been Gone," which has "a super radio-friendly hook." Elizabeth Lancaster of MTV Newsroom listed it as one of five key tracks in Stronger, writing "Upbeat yet soulful, the chorus will drag you up and onto the floor to dance the heartache away alongside her." Grady Smith of Entertainment Weekly thought that the song's "belty pop/rock wheelhouse" should please fans of the sound. He later added that "Clarkson might have been better off releasing "What Doesn't Kill You" as the first track from Stronger." Another positive reception came from Glenn Gamboa of Newsday, who praised Clarkson for "infusing her tales of empowerment after a breakup with her unique combo of vulnerability and sass." Jonathan Keefe of Slant thought that the song is "tailor-made for radio play" and that "the chilly electro-pop that Greg Kurstin brings to the verses, suggests a top forty version of Robyn's "Call Your Girlfriend" (2010).
