About Fades & volume
Free in-browser tool for fades and volume shaping. Set a fade in and fade out with two numbers, or draw the volume curve directly on the waveform to duck a specific passage. Overlapping fades meet in the middle instead of producing a bump. Nothing is uploaded.

How your file is processed
Fades & volume tells you where processing happens. Browser-only operations keep the file on your device; transcription and server processing upload only the media they need and apply the account limits shown in the tool.
Frequently asked questions
Is Fades & volume free?
The tool shows its access rules before processing. Browser-only operations are free and need no account; transcription and server processing can require an account and use the limits of your plan.
Are my files uploaded anywhere?
It depends on the operation. Browser-only tools keep the file on your device. Auto subtitles uploads only detected speech segments, while server processing uploads the selected file; each tool states this before you start.
Which formats does Fades & volume accept?
The upload field and output selector show the formats available for that operation. Browser support and the selected codec can affect which output formats are enabled.
Does Fades & volume work on a phone or tablet?
Yes, on a current version of Chrome, Safari or Edge. Speed depends on the device, so a long clip takes longer on a phone than on a laptop — the tool tells you its limits up front rather than failing part way through.
Why can processing change the file?
Edits that change picture or sound require decoding and re-encoding. A container change or fast keyframe trim may copy packets instead. The tool states which path it uses, because re-encoding can change quality, size or metadata.
