Q: What’s an M4A file, and why convert it on RunConvert?
A: M4A files are like AAC’s close cousin, often used by Apple for iTunes and iPhones. They sound great but aren’t always compatible with every device. RunConvert lets you convert them to MP3 for wider use or WAV for editing. It’s like turning an Apple-exclusive recipe into a global dish. RunConvert’s got you covered, wherever you are!
Q: Can I adjust the quality of my converted audio?
A: Yes, you can adjust the quality when converting. For higher fidelity, choose formats like FLAC or WAV. If you're okay with a bit of compression, MP3 or OGG are great choices. You control the quality, you know?
Q: How long will it take to convert my audio file?
A: Most of the time, the conversion takes just a few minutes. However, it depends on the file size and the format. Larger files or more complex conversions can take longer, but we’ll get it done as quickly as possible.

Q: Can I convert audio to video formats?
A: Not exactly. While RunConvert handles audio-to-audio conversion, for audio-to-video conversion (like turning your audio into a video file with visuals), you’ll need a video editing tool. Afterward, you can upload it and convert the audio portion!
Q: Can I convert audio to a format for mobile game sounds?
A: Yep, you can convert your sound effects, background music, and more into formats like OGG or MP3, which are commonly used for mobile games. Just upload your files, convert them, and you’re good to go!
Q: Can I convert audio from a YouTube video to a music file?
