What's the difference between Personal and Studio?

Personal ($39) is for one person — unlimited use on one active device at a time. Activate on a new device and the old one signs out. Studio ($199) is for teams and commercial client work — unlimited team members, early access to new tools, and a commercial license.

Do I need an account?

No. Use any tool free up to 5 times per day on compute-heavier tools, and unlimited on lightweight ones. No card, no account, no signup required.

Where are my files processed?

Right on your device. Files never upload to any server. Everything runs in your browser — you can verify in DevTools → Network.

What happens if I use my Personal license on a second device?

The new device activates and the old device signs out. Your license key stays the same — you just move it between devices as needed. No limit on how often you switch.

Does this work on my phone?

Yes. Every tool works on iPhone, Android, tablet, and desktop.

What if I want a refund?

30-day money-back guarantee on both tiers. No questions asked. Email sales@cipherforces.com.

Will you add more tools?

Yes. New tools ship regularly. Your license includes every tool we ever release — Studio members get early access.

About Audio Converter.

Convert Audio Between MP3, WAV, AAC, OGG, and FLAC

Drop any audio file and CipherForces converts it to your target format using FFmpeg compiled to WebAssembly. All processing happens in your browser — your audio never uploads.

First use downloads ~25 MB of FFmpeg-core from the unpkg CDN (cached after). On a modern laptop, a 3-minute song converts in 2-5 seconds.

Common Use Cases

Podcast production: Convert WAV masters to MP3 for upload to podcast hosts.
Music library: Convert FLAC archive to AAC for iPhone or Apple Music.
Sample conversion: Turn OGG game assets into WAV for further editing.
Phone ringtones: Convert any format to short M4R (AAC) for iOS ringtones.

Key Features

5 target formats: MP3, WAV (uncompressed), AAC, OGG, FLAC (lossless).
Bitrate control: 64, 96, 128, 192, 256, 320 kbps for lossy formats.
Sample rate: 22050, 44100, 48000 Hz.
Batch mode: Drop 10 files, convert them all in sequence.

Privacy: FFmpeg runs as WebAssembly in your browser. Audio data never leaves your device.
