## Overview

Scribd Downloader is an interactive Python utility that turns a Scribd document URL into a locally saved PDF. The main workflow validates and converts the URL, opens the embed in headless Chrome, prepares and loads document pages, prints each page, then merges the page PDFs. The README also documents direct batched loading with a scrolling fallback, layout cleanup, dynamic page sizing, and bounded-memory export. The implementation is concentrated in one script; omitted source excerpts limit certainty about some internal call wiring.

Main entry points: [`scribd-downloader.py`](https://github.com/themrsami/scribd-downloader/blob/main/scribd-downloader.py) (Interactive runner)
