Why iPhone's Full-Page Screenshot Doesn't Work in Most Apps (And What to Do)
Full Page depends on the app and view, not just Safari. Why it may be missing, and three ways to capture content when it is.
If you've ever taken a screenshot in Messages, WhatsApp, or Instagram and looked for the "Full Page" tab, you already know: it isn't there. It appears when the current app and view support full-page capture. Safari is the familiar example.
This isn't a bug. It's how the feature is built.
Why it only works in some apps
iPhone's full-page screenshot doesn't actually "scroll and capture." It asks the app to hand over the entire page as a document. Safari can do that because a web page is one long document. Apple’s iOS 13 release notes also list Mail messages, iWork documents, and Maps. That is a list of supported uses from that release, not a promise for every screen today; in Maps it can remove controls rather than capture an endlessly scrolling map. Apple’s current guide does not provide a complete app list.
Third-party apps can support it too. A chat view may load messages only as you scroll and may not provide a full document. If that view does not provide one, the Full Page option does not appear.
What you can do instead
-
Take overlapping screenshots and stitch them. This works in apps that allow screenshots. Scroll, screenshot, scroll a little less than one screen, screenshot again. Keep a bit of overlap between each shot, then use a stitching app to merge them. This is the most reliable method and gives you a clean, full-resolution image.
-
Screen-record while scrolling. Start a screen recording from Control Center, scroll slowly through the content, stop. Some stitching apps (Picsew is one) can turn the recording into a long image. Faster for very long threads, but sensitive to scroll speed.
-
Use the app's own export, if it has one. Some apps can export a conversation or page as PDF or text. Check the share sheet first; it's occasionally the cleanest option.
Which method to pick
| Situation | Best method |
|---|---|
| A few screens of chat or comments | Overlapping screenshots |
| A very long feed or article | Screen recording |
| You need text, not an image | App's own export |
About stitching apps
The main ones are Tailor (free, very simple; its release notes say third-party ads were removed), Picsew (the most features, some paid), and Stitch It (good redaction tools, also on Android). I made a fourth one, LongShot, because I wanted the simple version without ads: take the screenshots, double-tap the back of your iPhone, and a small matching group can be stitched into Photos, once a compatible version and the shortcut are set up. It checks overlap before merging, which reduces bad joins; it cannot guarantee every result. If it asks you to open the app, review the screenshots there.
Whichever you use, the trick is the same: leave enough overlap between screenshots.
