Web Screenshot Tool

The tool captures a web page screenshot by rendering the target URL in a headless browser and exporting a raster image. It supports configurable viewports and both full-page and viewport-only captures. Developers and QA teams gain a reproducible visual artifact suitable for PR validation, release notes, and documentation. The system is designed to work with public pages, including GitHub Pages, and can be integrated into CI pipelines or API workflows. Core features include URL input, viewport presets, full-page capture, image format choice, and output delivery as an image file. Conceptually, rendering relies on a browser automation layer to render the page at a defined size, then encodes the DOM visualization into PNG or JPEG for stable asset generation. Unique value lies in deterministic sizing, consistent rendering across environments, and easy integration into documentation and QA processes. Use cases include documenting UI changes, validating layout on different devices, and archiving project pages after releases. The tool avoids UI and front-end behavior discussions, focusing strictly on rendering logic, data flow, and output formats.
