The official music video for the song was directed by Declan Whitebloom and chronicles the singer chasing a male love interest she meets at a diner, intertwined with footage of Duff performing choreography with her dancers.

[4][5] The song received mostly favorable reviews from music critics,[6] and debuted at number 79 on the Billboard Hot 100 chart.

[11] Its instrumentation consists of a banjo, handclaps, and the "heavy hand" of a drum, which according to Carolyn Menyes of Music Times, results in the song sounding like "a big ol' stomping party".

[12] Seventeen magazine's Kristin Harris found the song to sound like a mix of Taylor Swift, The Lumineers, and "old-school Hilary".

[10] Emily Blake of MTV News echoed the same thought, writing that the guitar-driven track starts out like a Lumineers or Mumford & Sons joint but noticing that it "builds into something far more peppy, poppy and, well, Hilary Duff.

According to Nolan Feeney of Time magazine, "All About You" is in the "same twangy folk-pop vein" as "Chasing the Sun", but that it is a "huge improvement", writing that "All About You" has the "kind of rowdy punch" that is required to get a comeback "really cooking".

[9] Jason Lipshutz of Billboard praised the song, naming it "a no-nonsense pop tour de force," [with] the folk undertones, handclaps, shout-along chorus and deliriously enjoyable melodies [that] make this the winning comeback bid that Duff fans were hoping to hear when she announced her return to music.

"[17] Michelle McGahan of Pop Crush was complimentary with the folk-rock tone for "add[ing] a rich depth and maturity to Duff's sound [...] that is only enhanced by the slightly provocative lyrics.

"[26] Duff wrote on her Twitter account on 4 September that she was filming the single's music video, which was directed by Declan Whitebloom.

[28] As described by Thomas Chau of Pop Crush: "The Cinderella-esque video begins with Duff innocently sitting in a diner when glances across and sees a hunky guy not far from her.
