Frequently asked questions
Does my file upload?
No — it compresses in your browser; nothing leaves your device.
Is it free?
Yes. Free, no signup, no limits.
Will it lower the quality?
Compression trades some quality for size; pick a higher bitrate to keep more quality, or a lower one for a smaller file.
Why compress before transcribing?
Smaller files send faster. Transcription quality depends on clarity, not file size, so light compression is usually fine.
