I like the iOS PageCapture here. I want to find it for Desktop. Where can I find such whole-browser-page-screenshotting app for OSx?
Paparazzi isn't a good app. I used it and it didn't work or was very slow to load.
I use a lot Layers Shot and W3Capture, they save the multiple pages or sites and also capture ones whole pages. Layers save as PDF, PNG, TIFF or PSD file. W3Capture, as PDF (separated pages) and PNG (one whole page). I also used a lot Web Slices (free), a sites sncreenshot app.
Go to the Mac App Store, search the apps and follow the apps:
Out of Mac App Store, W3Capture's link:
More apps that I didn't test yet:
I hope this answer help you. Good luck with these apps!
If you don't want to use OSx apps, go with your browser -- use Awesome Screenshot Capture -plugin in Chromium here. It has also annotating -features.
