Frequently Asked Questions

Will converting my MP3 to WAV make the sound quality better?

Honestly, no. MP3 is already a "lossy" format, meaning some audio data was permanently deleted to save space. Converting it to WAV won't bring that lost data back, but it will stop your audio from losing even more quality if you plan to edit or remix it in music software.

Why do game developers prefer OGG over MP3 for background music?

Because MP3 files naturally have a tiny, annoying gap of silence at the very beginning and end. If you try to loop a background track in a game, it will stutter. OGG allows for perfect, seamless audio looping, which is why it is the go-to format for games and apps.

I downloaded a video from social media and it's a WEBM file. Can I turn it into a song?

Yes. WEBM is a highly compressed format used by major video streaming websites and social platforms. Since most default music players can't open WEBM, converting it to MP3 is the fastest way to turn those trending web clips and music videos into offline songs for your phone.

I need to edit an interview recorded on my Mac/iPhone. Should I use MP3 or WAV?

Choose WAV. Your iPhone or Mac recorded the MOV video with high-quality audio. If you convert it to MP3, you compress it and lose detail. Converting MOV to WAV extracts 100% uncompressed raw audio, ensuring your video editing or audio tools get the cleanest sound for smooth editing.

I have a whole folder of voice memos. Do I have to upload them one by one?

Not at all. You can drop all your voice memos into our tool at once. The batch conversion feature allows you to process dozens of MP3, WAV, or M4A tracks simultaneously, saving you from the tedious headache of clicking through them one by one.

Will changing the format ruin my song's sound quality?

No, it depends on your choice. Moving between lossless formats like WAV and FLAC keeps your audio 100% untouched. However, if you convert a high-quality file into a compressed format like MP3, some subtle sound details are removed to shrink the file size, which might slightly affect how it sounds on professional headphones.
