WebM is an open, royalty-free video format launched by Google in 2010 as part of the WebM Project. Based on the Matroska container, WebM pairs VP8, VP9, or AV1 video with Vorbis or Opus audio (typically 64-160 kbps). The format was designed specifically for HTML5 video delivery, offering efficient compression without patent licensing fees. Opus audio, in particular, achieves excellent quality at low bitrates—often matching MP3 quality at half the file size.

WebM files are commonly encountered from YouTube downloads (youtube-dl, yt-dlp), screen recorders, and web-based video tools. YouTube uses WebM as one of its primary delivery formats, making it a frequent source for audio extraction. While Chrome, Firefox, and Edge play WebM natively, other devices may lack support—extracting to MP3 or WAV ensures universal compatibility.
WAV (Waveform Audio File Format) is an uncompressed audio format developed by Microsoft and IBM in 1991. It stores raw PCM (Pulse Code Modulation) audio data, preserving every sample from the original recording without any quality loss. WAV supports 16/24/32-bit depth, sample rates from 8 kHz to 192 kHz (commonly 44.1/48 kHz), and up to 65,535 channels. It's the standard working format for audio professionals in recording studios, broadcast facilities, and sound design workflows worldwide.

The main tradeoff is file size: a 3-minute stereo track at CD quality (44.1kHz, 16-bit) is approximately 30 MB. While this makes WAV impractical for streaming or portable devices, it remains essential for editing, archiving, and any workflow where audio quality is paramount. Converting to MP3 reduces file size by 90% or more while maintaining perceptually transparent quality for most listeners.

How are credits calculated for this conversion?
Cost: 1 credit per 5 minutes
How it works:
- Files up to 5 minutes: 1 credit (minimum)
- 6-10 minutes: 2 credits
- 11-15 minutes: 3 credits
- 16-20 minutes: 4 credits
Example: A 10-minute file = 1 credit. A 180-minute (3h) audiobook = 36 credits.
Why per-minute? Audio conversion time scales with content duration, not file size. Longer audio requires proportionally more processing.
What are my daily and monthly credit limits?
Credit allocations vary by account tier:
| Tier | Daily Limit | Monthly Limit |
|---|---|---|
| Free | 50 credits/day | — |
| Pro | — | 10,000 credits/month |
| Business | — | 30,000 credits/month |
Daily credits (Free tier, including guests) reset every day at midnight UTC. Monthly credits (Pro & Business) reset on your billing cycle date.
Note: With 1 credit per 5 minutes, video files under 5 MB cost 1 credit each. Pro users can convert 10,000 video files per month.
