A changelog with forty entries, a Slack thread that scrolled past the top of the window an hour ago, a full web page with a footer you've never actually seen — these are the captures a plain screenshot can't handle, because a plain screenshot only sees what fits on screen at once. Scrolling Capture exists specifically for that case: frame a region, and the app drives the scrolling, captures each step, and hands you back one continuous image.
Starting one
Scrolling Capture has its own global shortcut, Control+Shift+V, and a horizontal variant on Shift+Cmd+7 for wide content. It's also reachable mid-selection from the All-in-One overlay: frame the area you want the way you would for a region capture, and it takes it from there.
Driving the scroll
Because ScreenClipr is scrolling a window that belongs to a different app, it needs the Accessibility permission in addition to Screen Recording — this is the one feature in the app that reaches out and drives another application rather than just reading the screen. Under the hood, the loop is genuinely simple: capture the framed region, post a scroll event into the target window, wait briefly for the view to settle, capture again, and repeat. macOS routes scroll events to whichever app is currently active rather than whatever's under the pointer, so ScreenClipr briefly activates the window it's scrolling for the duration of the capture and hands focus back to whatever you were using the moment it's done.
Knowing when to stop
Every new frame is compared against the previous one using a lightweight brightness signature — not a pixel-perfect diff, just enough of a fingerprint to tell "this changed" from "this didn't" cheaply, frame after frame. When two consecutive frames come back close enough to identical, the app concludes it's reached the bottom (or the right edge, for a horizontal capture) and stops — requiring two matching reads in a row rather than one is deliberate, since the very first comparison after the first scroll step is measurably less reliable than every later one. Left unattended, the loop keeps going for up to 60 scroll steps, which comfortably covers everything from a long chat thread to a full changelog page.
Stitching without a visible seam
Each captured frame overlaps a large part of the one before it, since the scroll step is smaller than the visible region. To join them, the app finds exactly how far the content moved between each pair of frames by comparing the overlapping rows and locating the offset where they line up best — it doesn't just trust the pixel distance it commanded the scroll to move, because a page's last scroll before hitting bottom is often shorter than every step before it. Only each frame's genuinely new content is appended to the growing image, so you get one continuous capture rather than a column of overlapping duplicates.
The other thing that makes a naive scroll-and-stitch look broken is a sticky header or footer — a nav bar or a "reply" toolbar that stays pinned in the same place while everything else scrolls past it. ScreenClipr detects rows that stay identical across every captured frame from the top or bottom edge inward, and keeps that band exactly once in the final image instead of once per frame. That's what keeps a stitched capture of a page with a sticky nav from repeating that nav bar down the entire length of the image.
The horizontal variant
Wide tables, spreadsheets, and timelines need the same idea turned sideways: instead of scrolling down, the app scrolls right, and instead of a repeating header, it watches for a sticky left or right column (a frozen row-label column is the common case). It's the same underlying capture-compare-stitch logic, just applied along the horizontal axis — reachable with its own shortcut, Shift+Cmd+7, for exactly the cases a vertical scroll can't help with.
When to reach for it
- Long changelogs and release notes — capture the whole thing in one pass instead of stitching screenshots by hand afterward.
- Chat threads — a Slack, Discord, or Messages conversation that's scrolled well past what fits on screen.
- Full web pages — an article, a docs page, or a long form, top to bottom, in one image you can annotate as a whole.
- Wide tables and spreadsheets — anything that scrolls sideways instead of down, using the horizontal variant.
If the target window doesn't respond to the scroll at all — or was already sitting at the very bottom — the app still hands you back a genuine still image of what was framed rather than failing silently; it just won't be the multi-frame panorama the feature is built for. For everything else, it's the difference between five separate screenshots taped together in an editor and one clean image you can search, annotate, and share as a single file.
