Browser Screen Recorder with Microphone Audio

Both, and from two places at once. Your microphone gives the narration; the system or tab audio gives whatever the machine is playing, which is what you want when the point of the recording is a video or a call. The browser's share dialog is where the second one is granted — if the sound is missing afterwards, that checkbox in the dialog is almost always the reason.

MP4 with H.264 video and AAC audio — the format that opens everywhere without conversion. Where the browser cannot encode H.264 (Yandex Browser on some computers, Firefox always), the recording is saved as WebM, and a “Make MP4” button appears next to Download: it converts the recording right on the page.

Yes. A transcript panel opens when you stop, turning the speech into timestamped text you can search, and it exports to SRT or VTT if you want subtitles rather than a document. Recognition runs in the page through WebAssembly, so the accuracy depends on the recording rather than on a connection: a headset microphone and one speaker at a time will be transcribed well, while system audio from a call with three people talking over each other will not. Live captions during recording appear where the browser provides speech recognition; if its service does not answer, you can still get the text after recording. How many transcripts a day you have is shown above the transcript button.

In Chrome, Yandex Browser, Edge and Opera the recording is written to the device's disk in pieces as it goes, so even a session of several hours does not pile up in the tab's memory, and a take cut short by a reload or a crash comes back from the recordings history. The limit is free disk space: when it runs low, the recording stops by itself and the file is kept whole. Firefox holds the recording in memory — there it is safer to split long sessions. How much you can record without Premium per take and per day is shown above the Record button.

Windows 10 draws it when the browser records a single window — it is how the system shows that the window is being captured. On Windows 10 neither a website nor the browser settings can turn it off; on Windows 11 Chrome removes it by itself. The border does not end up in the file. To keep it off your screen too, pick Entire screen in the share dialog and turn on Screen area — drag around the game or app window, and only it will be recorded. Usually you get more frames this way as well: on Windows 10 capturing the entire screen runs faster than capturing a single window.
