Social Preview Generator

About

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. The extension does not upload screenshots to a server, does not require an account, and does not depend on a backend service.

Key features:
- Capture the current visible tab
- Export a fixed 1200 x 630 PNG
- Drag vertically to refine the crop
- Use immediate capture or 3s / 5s delayed capture
- Works with staging sites, localhost, and logged-in pages already open
- Local-only processing with no remote upload
