Pas de problème means “no problem.” It is used to reassure someone that something isn’t an issue, or to accept a request casually.

Literal meaning: “not of problem” or “there’s no problem” (pas de = “no/not any” + problème = problem). The literal and actual meanings line up almost exactly here with no idiomatic gap.

Pronunciation: The French phrase pas de problème is pronounced pah-duh-praw-blem

When to use it: Examples

• Reassuring someone → “Désolé du retard.” “Pas de problème.” (Sorry I’m late. No problem.)
• Accepting a request → “Tu peux m’aider?” “Pas de problème.” (Can you help me? No problem.)

Register: Informal. It reads as polite-casual, so it’s safe with strangers, service staff, and mild formal contexts (customer service, a helpful colleague).

vs. “De rien”: De rien responds specifically to thank you (“you’re welcome”). Pas de problème is broader — it responds to an apology, a request, or a thank-you, and leans more “it’s fine / don’t worry about it.”
