Questions
How do I record my voice and computer sound together?
Turn on Microphone and Computer sound, press Start recording, then turn on the sound switch in your browser's window. Both go into one sound track. Computer sound works in Chrome and Edge.
Is my recording uploaded?
No. It stays on your device, and FizzyTools never receives it.
Is there a time limit or a watermark?
No watermark, and no time limit. The free space on your device sets the limit: an hour at HD takes about 2.3 GB.
What if my browser crashes?
Your recording is saved as it runs. Open this page again and we'll offer it back, with at most the last second or two missing.
Can it record computer sound?
In Chrome and Edge, yes: turn on the sound switch when you choose what to share. Tab sound works on every computer, and whole-screen sound depends on your system. Firefox and Safari can't record computer sound, but your microphone works in all of them.
Do I need permission to record something?
Record only what you have the right to record. Recording someone else? Ask them first. The rules differ from place to place. This isn't legal advice.
Why is part of my recording black?
Some films and shows are protected by their owners, and your browser keeps them out of recordings. We can't change that and don't try to.
Can I record on my phone?
Most phones don't let websites record the screen, so use your phone's own screen-record control. You can record your camera here. iPhones and iPads with iOS 27 can share their screen in Safari.
Why doesn't my trim start exactly where I chose?
A clean cut starts on the next clean frame, so nothing before it stays in your file. In Chrome and Edge, Exact cut re-makes the video and starts where you chose.
Where does my recording go afterwards?
Recordings you've saved are removed from this browser on your next visit. Ones you haven't saved stay until you save or delete them. Browsers can clear stored data, so save important recordings soon.
Does it work in a private window?
Yes, for shorter recordings: a private window has less room, and a crash can't be recovered there.
