How2 Mac: Quick Look Is the Secret Superpower You're Ignoring

🖱️ The Basics: Select, Spacebar, Done

Quick Look is the fastest file preview on any computer, and it's been on your Mac the whole time. Click any file once, then tap the spacebar — a preview window pops up instantly.

• Documents & PDFs: read pages right in the preview.
• Photos & images: full-resolution glance without opening Photos.
• Videos & audio: press play directly in the preview window.
• Arrow-key surfing: keep the preview open and tap up/down to move through a whole folder.

It also works inside Open and Save dialogs — preview before you commit.

⚡ Power Moves Most People Miss

Tap the fullscreen icon (or hold Option while pressing spacebar) for a distraction-free full-screen preview. Select a whole folder's contents and hit spacebar for an instant slideshow — complete with forward/back controls.

• Force Touch: hard-press a file on a trackpad to peek at it without lifting a finger.
• Markup in preview: click the pencil icon to annotate a PDF or image right inside Quick Look, then share it — no Preview app required.
• Third-party plugins: free Quick Look plugins add previews for code files, ZIP contents, Markdown, and more.

🚀 Workflow Wins That Add Up

• Attachments: preview email and Messages attachments before deciding whether to download them.
• ZIP archives: with a plugin, peek inside compressed files before extracting.
• Code & text files: glance at scripts and config files without opening an editor.
• Downloads triage: spacebar through your Downloads folder and delete the junk in seconds.

Try this challenge: for one day, never double-click a file you just want to look at. Quick Look it instead. You'll wonder how you ever tolerated the wait.
