App to Create Scroll Screenshot on macOS

by Rian

Though many browsers already support exporting a webpage as a long screenshot (or a scroll screenshot), from my experience, it doesn’t help the fact that it is filled with non-essentials. It’s a fact of all media. If you are saving only certain part of the post, exporting the entire page into PDF or JPEG is likely a step that will produce quite a lot of waste. And unlike iOS, screenshot tools on macOS are generally too expensive for one feature.

ScrollSnap is a freely available (from GitHub, $4.99 from Apple App Store) scroll screenshot tool. The idea and the execution are rather simple, though different from how it is usually done on iOS side. Upon launching the app, a user can select the window where the app would detect and record from. By manipulating what is displayed on the window (i.e. scroll the contents), the app is fed what it will make a scroll screenshot from.

When I began looking for a scroll screenshot tool on macOS, most of the forums guided to Photoshop’s photo merge feature, which was a complete overkill. Not only the subscription is beyond what I would pay for ($22.99/mo), the documentation seems to suggest it was meant for regular photos with extra bells and whistles I would never need with screenshots. Same for other professional screenshot tools too — I would only use one feature out of the dozens. I think the free app did the good job of what I was looking for. And it is also up to date; some tools are not updated for Tahoe.
