An ordinary iPhone screenshot captures what is on screen and nothing more. For a long article, a receipt, a chat thread or a terms page, that means stitching together six images and hoping nobody notices the seams.
iOS has captured entire scrolling pages for years, as a single file. The feature is real, it is built in, and it is hidden behind a tab most people never notice.
The method
- Open the page in Safari.
- Take a normal screenshot. On Face ID phones, press Side button + Volume Up. On models with a Home button, press Home + Side button.
- Tap the small preview that slides into the bottom left corner. You have about four seconds before it vanishes.
- At the top of the editor, switch from Screen to Full Page.
- Tap Done, then Save PDF to Files.
The entire page is captured, top to bottom, however long it runs. A scrollbar appears down the right of the preview showing just how much you have.
Miss the preview thumbnail and the option is gone. The full page version is not retained, so you have to take the screenshot again.
Why it saves as a PDF
This is the part that frustrates people, and it is a deliberate limitation rather than an oversight.
Full page captures save to Files as a PDF, not to Photos as an image. A very long page would produce an image thousands of pixels tall, which the Photos app handles poorly and most apps refuse to display sensibly.
The upside is that the PDF keeps selectable text, so you can search it later and copy from it. That is genuinely more useful than a picture, particularly for receipts and confirmations.
If you specifically need an image, open the saved PDF, screenshot individual pages, or use the Markup tools to export. There is no built-in one-tap conversion.
It does not work everywhere
The Full Page tab only appears in apps that have implemented support for it. Safari, Mail, Notes, Files and Pages all work. Most third-party apps do not.
So you cannot capture a whole WhatsApp conversation, an entire Instagram feed or a long thread in a social app this way. If the tab is missing, the app has not enabled it and no setting on your side will change that.
The workaround for those is Chrome or Safari’s reader view where a web version exists, or the app’s own export or share function, which often produces something cleaner than a screenshot anyway.
Trimming before you save
The editor lets you crop before saving, which is worth doing. Web pages captured in full tend to include a cookie banner at the top and a wall of footer links at the bottom.
Drag the corner handles to frame just the part that matters. Cropping here is faster than opening the PDF later, and it keeps the file to a sensible size.
The markup tools are available too, so you can circle the relevant line or black out an account number before the file leaves your phone. Do note that drawing a black box in Markup genuinely covers the pixels in the exported PDF, unlike some redaction tools that merely draw over recoverable text.
Faster ways to take the screenshot
Back Tap is the most useful iPhone setting almost nobody enables. Under Settings, Accessibility, Touch, Back Tap, assign Screenshot to a double tap on the back of the phone. It works through most cases and saves the button gymnastics entirely.
AssistiveTouch puts a floating on-screen button that can be set to screenshot, which helps if a physical button is broken.
You can also ask Siri to take a screenshot, though not to take a full page one.
The print trick for stubborn pages
If Full Page is unavailable but the content is on the web, there is a reliable fallback. Tap Share, choose Print, then pinch outwards on the print preview thumbnail. iOS turns the preview into a full PDF you can save or share.
It is an odd, undocumented gesture, and it has worked for years across a lot of iOS versions. For anything printable it captures the whole document regardless of length.
