Make quiet videos easier to hear
Some recordings are mastered quietly, and the site player stops at 100%. UVE can raise loudness above that limit on compatible HTML5 video, then mute or drop back from the same popup.

The problem
The player is already at maximum, and it is still quiet.
Laptop speakers, soft lecture mics, and older uploads often run out of headroom before you do. UVE applies a software boost in the browser — it is not a hearing aid and it does not make high volume safer.
Adjust without leaving the video
Q and E step volume. M mutes. You can also drag the control in the extension popup.
Save speed and loudness together
Named templates store both. Share them across tabs, or keep one tab’s mute and volume to itself.
Responsible listening
More loudness, with a clear limit.
Software amplification can clip when the source is already loud. Start near 100% and increase only while speech stays clear. This is not medical advice and it does not protect hearing.

Open Controls
Install UVE, start playback, and open the popup.
- 02
Raise volume carefully
Move past 100% only when needed. Lower the boost if audio breaks up.
- 03
Keep a useful level
Save a template or leave sharing off so the next tab is not muted or boosted by accident.
When a boost helps
Quiet sources, not every soundtrack.
A boost cannot fix a damaged file, and it will not apply to every protected player.

Bring a soft instructor forward without a separate desktop audio utility.

Compatibility and safety answers.
Can UVE boost quiet video audio?
Yes on compatible HTML5 video and audio. Free boosts up to 200% above normal player volume. Pro unlocks up to 600%. Increase gradually to avoid clipping.
Does boosting volume protect my hearing?
No. A louder signal is not safer. Keep device output comfortable and lower the boost if it hurts or distorts. UVE is not a medical device.
Does volume boost work on every compatible site?
Some protected or non-HTML5 players will not allow extension audio control. Results vary by site.
Does UVE remember volume?
Templates can store speed and volume together. You can share the current level across tabs or keep a tab independent.
Is there a free version?
Yes. Free includes volume boost up to 200%, speed up to 3×, and keyboard shortcuts.
Raising playback loudness does not make headphones or speakers safer. Use a comfortable level and stop if you hear distortion.
