Frequently Asked Questions
Everything people ask before using trim audio.
Yes. When you leave the output format set to “Same as input”, AudioKit copies the underlying audio stream without re-encoding it, so the trimmed result is bit-for-bit identical to the original for that section. Choose a different format only if you actually want a conversion.
Trim removes everything outside your selection, so to remove a middle section you would trim the two parts around it and then join them with Merge Audio. That two-step approach keeps both halves at full quality.
No. AudioKit processes every file locally in your browser using WebAssembly. Your audio is never transmitted to a server, never stored, and never seen by anyone but you. You can even disconnect from the internet after the page loads and the tools keep working.
You can open MP3, WAV, OGG, FLAC, AAC and M4A files. Output formats depend on the tool — Convert Audio can write MP3, WAV, OGG, FLAC, AAC and M4A.
Yes, completely. There is no signup, no watermark, no file limit and no paywall. AudioKit is funded by optional donations, so the tools stay free for everyone.
