How to Take a Scrolling Screenshot on Mac (Full Page, 2026)
macOS has no built-in scrolling screenshot. Here are 3 ways to capture an entire web page or long chat on Mac — Safari DevTools, Chrome DevTools, and Snappix's one-click auto-scroll capture.
A regular screenshot only captures what fits on your screen. When you need the whole web page, the entire chat thread, or a full document — everything below the fold — you need a scrolling screenshot. And here's the short answer: macOS has no built-in scrolling capture. The ⌘+Shift shortcuts only grab the visible screen.
The good news: there are three reliable ways to take a full-page screenshot on Mac, and one of them takes a single click. Let's go through them.
Option 1: Safari's Built-in Full-Page Capture
Safari hides a full-page screenshot tool in its developer menu:
- Open Safari → Settings → Advanced → enable Show features for web developers.
- Open the page you want to capture.
- In the menu bar: Develop → Show Web Inspector (or ⌘+Option+I).
- In the Web Inspector's Elements panel, right-click the top
<html>node and choose Capture Screenshot — Safari exports a full-size PNG of the entire page.
Limits: it only works in Safari, the output is a plain PNG with no annotation, and very long pages can fail or produce gigantic files.
Option 2: Chrome DevTools Command
Chrome can also capture full pages, via its command menu:
- Open Chrome → press ⌘+Option+I to open DevTools.
- Press ⌘+Shift+P to open the command menu.
- Type
captureand select Capture full size screenshot. - Chrome downloads the complete page as a PNG.
Limits: same story — DevTools-only, no editing, and it captures the layout of the page (sticky headers and lazy-loaded images may render oddly). For everyday captures of chats, apps and documents it's useless, since those aren't web pages at all.
Option 3: Snappix — One-Click Scrolling Capture (Any App)
Both built-in methods only work in a browser. If you want to capture a long Slack thread, an email thread, a CodePen, a Notion page or anything scrollable in any app, you need a dedicated scrolling capture tool. Snappix does it in one click:
- Install Snappix — download it free and it lives in your menu bar.
- Open the capture menu and choose Scrolling Screenshot.
- Click the window you want to capture. Snappix scrolls the content and stitches frames together automatically — no manual overlapping.
- Stop or let it finish — it detects the end of the page on its own.
- Annotate and export — mark it up with arrows and highlights, then save as a tall PNG or a paginated PDF.
Because it scrolls whatever is on screen, it works in every browser and every app — no per-site integration, no DevTools. The PDF export is particularly useful for receipts, articles and documentation you want to print or archive. (Full scrolling screenshot guide →)
Which Method Should You Use?
| Method | Works in | Output | Best for |
|---|---|---|---|
| Safari DevTools | Safari only | PNG | Occasional full-page web captures |
| Chrome DevTools | Chrome only | PNG | Web developers debugging layouts |
| Snappix | Every app & browser | PNG / PDF | Daily full-page captures, chats, docs |
If you only need a full-page web capture once a month, the DevTools routes are fine. If you capture full pages, long threads or documents regularly, the one-click tool pays for itself the first week.
Bonus: Turn Full-Page Captures into PDF
Scrolling screenshots shine when exported as PDF: pages are paginated automatically, text stays selectable for search, and files open anywhere. Snappix exports any scrolling capture as PDF in one click — no Preview round-trip needed. We cover the full workflow in how to convert a screenshot to PDF.
Ready to Capture Full Pages in One Click?
Stop stitching screenshots by hand. Snappix auto-scrolls, stitches, annotates and exports full-page captures as PNG or PDF — bundled with region capture, OCR, beautification and screen recording in a single Mac app.
