Frequently asked questions
What audio formats are supported?
The audio tools support common formats including MP3, WAV, OGG, M4A, AAC and FLAC for conversion and compression.
How can I make a quiet audio file louder?
Use the Audio Volume Booster to increase the gain of an audio file with an adjustable level, directly in your browser.
Can I cut a specific section out of an audio file?
Yes, the Audio Trimmer lets you select precise start and end points to cut a clip down to just the part you need.
Is there a file size limit for audio tools?
Audio files are processed locally in your browser, so practical limits depend mainly on your device's memory rather than a fixed upload cap — very large files may take longer to process.
