Looper
Loop YouTube Videos — A/B Repeat & Speed Control
Set precise A/B loop points on any YouTube video and repeat them at any speed. No signup, no download.
How it works
- 1
Bring in a video
Paste any YouTube link — a full watch URL, a youtu.be link, or a bare video ID — into the box, or swap "youtube.com" for our domain in the address bar of a video you're already watching.
- 2
Set your loop points
Drag the A and B markers on the timeline, or press A and B during playback to drop them at the current time. The section between them is what repeats.
- 3
Play, adjust, repeat
Playback loops automatically between A and B. Nudge the markers, change speed, or jump back in — the loop keeps landing precisely, not the sloppy near-second drift most tools give you.
- 4
Save or share it
Your loop is saved automatically to this browser, so it's there next time you open the video. Hit Share to copy a link that opens straight into the same loop for someone else.

Frequently asked questions
- Is Looper free to use?
- Yes. Looper is free, ad-supported, and doesn't require an account. Every feature — loop points, speed control, saving, sharing — works without signing up.
- Does it download or store the video?
- No. Looper plays the video through YouTube's own player and never downloads or stores video or audio — it only sets where playback starts and restarts.
- How accurate is the looping, really?
- Loop points are checked on every animation frame and the restart is timed to land right at your start marker, not up to a second late the way tools that check on a slow timer do — the gap most people notice as a stutter or a skipped word.
- Will my loop points be saved if I close the tab?
- Yes. Loop points, speed, and any notes are saved per video in your browser automatically. Reopen the same video later and your last loop is restored — no account needed.
- Can I share a loop with someone else?
- Yes. The Share button copies a link that encodes the exact video, loop points, and speed, so opening it drops the other person straight into the same loop.
- Does this work on my phone?
- Yes, the timeline, markers, and controls are built to work with touch, not just a mouse.
- Will it work on any YouTube video?
- It works on any public, embeddable YouTube video. A small number of videos have embedding disabled by their owner — those show a clear message rather than failing silently.
- Do I need to install anything?
- No. It runs entirely in your browser tab. Nothing to install, nothing running in the background.
