Mac – How to resize a web browser to force screenshots at a specific resolution on Mac OS

browser-addonsfirefoxmacresolution

I want to take screenshots in a web browser so that the resulting graphic (.png, .jpg) is a specific resolution, for example: 1024 x 768

Besides adjusting my monitor resolution, is there any way to do this with an application or plug-in/add-on specifically for Mac OS? There is a Firefox plug in called Window Resizer, but it does not work with newer versions of Firefox.

  • The last program I used for this was Gadwin Web Snapshot

    I do not recall all its features but I think it can achieve what is required here.

    Other options would be:

    • Screenshot - Webpage Screenshot, a Chrome extension that lets you take screenshots

      enter image description here

    • Capture Me, which is a flexible screen capture and recording utility for Mac OS X which features a floating capture window, several saving options, and resize ability.
