How to choose the right tool
Start from your source format (what you have today) and your target format (what the next app requires). Use the cards above for a visual overview, or jump straight to a popular converter below. If you are unsure, try the closest match and check the on-page FAQ for limitations.
For multi-step jobs—such as compressing after converting—open the first tool, download the result, then continue with a related utility listed on each tool page. This keeps quality predictable and avoids overloaded all-in-one settings.
