FAQ Frequently Asked Questions

What audio formats can I trim and convert?
The tool typically supports common formats including MP3, WAV, AAC, and OGG. Input and output format support depends on browser capabilities and the specific implementation of the Web Audio API.
Can I trim audio files without losing quality?
Yes, trimming removes sections without re-encoding the remaining audio, preserving original quality. However, format conversion may involve compression that could affect quality depending on the output format and settings.
Is audio processing done locally or on servers?
The tool processes audio locally in your browser using the Web Audio API and client-side libraries. Your audio files never leave your device, ensuring complete privacy for sensitive or personal audio content.
Can I see waveforms when trimming audio?
Yes, most tools display audio waveforms that help you visually identify the sections you want to keep or remove. This makes precise trimming much easier than relying on time markers alone.
What's the maximum file size I can process?
File size limits depend on browser memory and device capabilities. Most tools handle files up to 100-200MB effectively, though larger files may take longer to process or cause performance issues on older devices.
