About this extension
Every video, every stream, one comfortable volume.
You know the pattern. Dialogue so quiet you lean in, then an ad or a trailer that makes you lunge
for the volume key. Compressr fixes that at the source: it measures how loud audio actually is,
in real time, and rides it toward one steady level you choose.
WHAT IT DOES
• Loudness leveling — a broadcast-style loudness rider brings programme audio toward a consistent
target, so quiet and loud material arrive at the same comfortable level.
• Sudden Volume Protection — a fast detector catches abrupt bursts and pulls them down before they
reach you, then recovers gently rather than pumping.
• Dialogue clarity — optional presence shaping tuned to keep speech intelligible without making
everything sound bright.
• A/B and Fair Compare — hear the processing on and off. Fair Compare matches loudness between the
two so you judge the tone, not just the level.
• Presets for how you are listening — Balanced, Dialogue, Movie and Music, with a Night preset
and per-site settings in Pro.
PRIVATE BY DESIGN
Audio is processed inside your browser, on your device. No audio is recorded, uploaded or stored.
Compressr does not collect your browsing history, and it never changes your computer's system
volume — only what the browser plays.
FREE AND PRO
The core leveling and Sudden Volume Protection are free and need no account. Pro adds dialogue
clarity, the Night preset, A/B with Fair Compare, per-site profiles, and the advanced audio
controls.
