Brian Apps is a boutique Windows utility publisher whose entire catalog revolves around the single-minded but surprisingly versatile tool Sizer, a lightweight shell extension that lets designers, QA testers, streamers and productivity hawks snap any desktop window to an exact, preset dimension in pixels or percentages. Originally created to help web developers verify responsive breakpoints without manually dragging borders, the program now appeals to anyone who needs repeatable window geometry: support staff documenting ticket steps, gamers capturing fixed-size screenshots, presenters rehearsing layouts, or multi-monitor users who want consistent app frames across screens. Sizer quietly grafts itself onto every window’s context menu; right-click the title-bar or border and a cascading list offers choices such as 640×480, 800×600, 1280×720, or any custom combination the user has added. A real-time overlay confirms the new size before the change is applied, and optional hot-keys make the process even faster. Because the utility writes no files outside its own folder and consumes virtually no RAM, it is frequently carried on USB drives as a portable tweak. Updates over the years have added multi-DPI awareness, restored positions on dual monitors, and command-line scripting for automated testing pipelines. Brian Apps’ software is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always installing the latest version and supporting batch installation alongside other applications.
