SubAlign

The Universal Subtitle Positioner v3.6.6 is a powerful browser tool designed to give you complete authority over your video captions. By integrating directly into your favorite streaming platforms, this extension eliminates the frustration of poorly placed text that obscures facial expressions or critical action. You can achieve pixel-perfect vertical alignment using the distance adjustment tool, which offers a wide range of motion from -300 to +300 percent of the frame height. Beyond simple positioning, the extension allows you to toggle between straight and italic text styles to suit your personal reading preference or the aesthetic of the film. Once you have dialed in your ideal settings, a single click of the Apply Changes button locks your configuration into the active tab, while a dedicated Reset option remains available to quickly restore default layouts. Built on the secure and efficient Manifest V3 framework, it provides a seamless, high-performance experience across all URLs without slowing down your browser.
