Change Volume Online
Make sound louder or quieter in an audio file or video. For videos, the picture stays unchanged and the output keeps the same format.
Upload your file
Choose a volume level and process the sound locally in your browser. Videos keep the same format, while audio files can be exported to a format you choose.
Hints
- Wait for the current download to finish before starting another job, or it may fail.
- Very large files may take longer or fail on memory-limited browsers or devices.

Frequently asked questions
Does this normalize sound automatically?
No. This page applies a fixed volume change to the whole file. Use Normalize Audio when you want presets for podcasts, online video, broadcast-style sound, or uneven speech.
Can making sound louder cause distortion?
Yes. Boosting sound that is already loud can create harsh peaks. If the result sounds distorted, try a smaller boost or use the Normalize Audio page.
Are my files uploaded?
No. Processing runs in your browser, so your files are not uploaded to a server.
Can I keep the same format?
Yes. Videos keep the same format automatically. For audio files, choose the same output format as your input when you only want the volume to change.
