Format mismatches, sample rate conflicts, loudness drift
Video edits live at 48 kHz, music gets exported from DAWs at 44.1 kHz, and stock SFX come in any format. A film audio pipeline ends up converting between rates, depths, and containers constantly. Browser tools handle the small one-off conversions that don't justify booting Pro Tools for a 5-second clip.
For filmmakers and video editors, the typical workflow is: Source audio → convert → time → import to NLE. The WMA to MP3 fits in that chain by handling convert legacy windows media wma into mp3.. without leaving the browser, without uploading the file, and without a watermark.

Filmmakers FAQ
Why does video use 48 kHz instead of 44.1 kHz?
Broadcast standards. Cinema, broadcast TV, and streaming video all standardize on 48 kHz, while music streaming (Spotify, Apple Music) standardizes on 44.1 kHz. If your audio came from a music project, resample to 48 kHz before importing into your video timeline.
What loudness for streaming video?
Streaming video targets -23 LUFS for broadcast (EBU R128) or -16 LUFS for Netflix/streaming. YouTube uses -14 LUFS. Match the platform you're delivering to.
