ResLock for YouTube

About

Have you had enough of manually changing YouTube quality every time you start a new video? Tired of switching back to 1080p or higher on every single click?

ResLock solves that.

Set your preferred playback quality once, and ResLock applies it automatically whenever a video starts. No more digging through the settings menu. No more interruptions. Just consistent playback the way you want it.

If your selected quality isn’t available, ResLock intelligently falls back to the closest available resolution to keep playback smooth and stable.

Why ResLock is worth it:
- Saves time on every video
- Keeps your viewing experience consistent
- Reduces frustration from unwanted auto-quality changes
- Simple setup — works quietly in the background
- No ads, no clutter

Whether you prefer stable 720p on slower networks or sharp 1080p+ on a fast connection, ResLock ensures YouTube behaves the way you expect.
