Frequently Asked Questions

How do I zoom in on a PDF?

Same shortcuts work: Ctrl/⌘ + Plus to zoom in. Most PDF viewers also have zoom controls in the toolbar or View menu. Adobe Reader: Ctrl/⌘ + scroll wheel.

How do I make text bigger permanently?

Windows: Settings → Display → Scale (125%, 150%, etc.). Mac: System Settings → Displays → Resolution. This affects everything, not just browsers.

Why does Ctrl + Plus not work?

On some keyboards, use Ctrl + = instead (no Shift needed). The plus key and equals key are usually the same button. Numpad + also works.

Does browser zoom stay when I revisit a site?

Yes, most browsers remember zoom level per website. To reset all sites: Browser settings → Appearance or Page zoom → Reset or set default.
