Screen recording has quietly become an everyday skill. You need it to show a colleague where a button is, to keep evidence of a transaction that went wrong, to record a lecture, to capture something before it disappears, or to make content.
The useful thing to know is that every major platform now includes a screen recorder built in. Paid tools have their place for serious editing, but for most purposes you already have what you need and simply have not found it.
This guide covers each platform in turn, including the part that trips people up most: the audio.
Windows
Windows has two built-in options.
The Snipping Tool now records video as well as capturing stills. Press Windows + Shift + S, or open Snipping Tool from the Start menu, then switch from the camera icon to the video icon. Select the area you want and press Start. This is the simplest option for a quick clip of part of the screen.
Game Bar is more capable, and despite the name it records most applications rather than only games. Press Windows + G to open it, or Windows + Alt + R to start and stop recording directly.
Two limitations. Game Bar records a single application window rather than the whole desktop, and it will not record File Explorer or the desktop itself. For the full screen including the taskbar, use the Snipping Tool.
Recordings save to Videos, then Captures.
For anything more demanding, OBS Studio is free and open source, records the full desktop and multiple sources, and handles separate audio tracks. There is a learning curve, and it is the standard tool for good reason.
Mac
Press Command + Shift + 5. A toolbar appears with options to capture a still or record, either the whole screen or a selected portion.
Before recording, open Options in that toolbar. This is where you choose the microphone, set a countdown, and pick the save location. The microphone is off by default, which is the single most common reason people finish a recording and find it has no narration.
Stop from the menu bar icon or with Command + Control + Esc. QuickTime Player offers the same thing through File, New Screen Recording, and is convenient if you want to trim immediately afterwards.
iPhone and iPad
Built in, but hidden until you add it.
Settings, Control Centre, find Screen Recording, tap the green plus.
Open Control Centre — swipe down from the top-right corner, or up from the bottom on models with a home button — and tap the record button. A three-second countdown runs, then the indicator turns red. Tap the red indicator at the top to stop.
To record your voice, press and hold the record button rather than tapping it. A panel appears with a microphone toggle. Turn it on. Almost everyone misses this the first time.
Internal audio is captured automatically, so app sounds and video audio are included. Recordings save to Photos.
Turn on a Focus mode first — notifications appear in the recording.
Android
Available since Android 11, with placement varying by manufacturer.
Swipe down twice for the full quick settings panel and look for Screen Record. If it is not visible, tap the edit or pencil icon and drag the tile in.
Tapping it offers choices before it starts: whether to record audio, and whether to show touches. The audio option usually includes device audio, microphone, or both. Choose deliberately — the default is frequently no audio at all.
Samsung, Xiaomi, Tecno and Infinix each style this slightly differently, but the function is in quick settings on essentially all current devices. Recordings save to the gallery.
Getting the audio right
Two different sources, frequently confused.
System audio is what the device is producing — the video playing, the app sounds. Microphone audio is you talking.
Most tutorials want both. Capturing a fault usually wants only system audio.
On iPhone, system audio is automatic and the microphone needs the long-press. On Android, both are offered explicitly at the start. On Mac, the microphone is in Options, and capturing internal audio needs extra software because macOS does not route it to the recorder. On Windows, Game Bar handles both through its audio widget.
Before recording anything important, do a ten-second test and play it back. It prevents the particular frustration of finishing a twenty-minute recording that turns out silent.
Practical tips
Turn off notifications. Do Not Disturb or a Focus mode.
Check what is visible. Bookmarks, open tabs, desktop files, account names. Close anything you would not show a stranger.
Watch the file size. Screen recordings are large — a ten-minute capture can run to several hundred megabytes. If you plan to share it over mobile data, compress it first.
Record in shorter segments. Easier to redo, easier to share, far less painful if something fails.
Trim afterwards. Photos on iPhone, the Photos app on Windows and QuickTime on Mac all trim without extra software. Cutting the first and last few seconds where you are reaching for the button makes a real difference.
The short version
Windows uses the Snipping Tool or Windows + Alt + R. Mac uses Command + Shift + 5. iPhone needs Screen Recording added to Control Centre first. Android has a quick settings tile.
The audio is what goes wrong: long-press the iPhone record button for the microphone, check Options on Mac, choose your source deliberately on Android.
Turn on Do Not Disturb, close anything private, and test ten seconds before recording anything that matters.
