Social Preview Generator

Capture the current page locally and export a 1200x630 social preview image.

Social Preview Generator helps you turn the page you are already viewing into a ready-to-use social sharing image. Capture the current visible tab, fine-tune the vertical crop, and download a 1200 x 630 PNG for Open Graph and social preview use cases. Everything happens locally in Chrome.
