## Overview

ALL PDF is a browser-based PDF toolkit, also offered as a Telegram Mini App. The user chooses a tool, supplies local files, runs an operation, then downloads its result; the README says files stay on-device. The app routes to specialized tool pages, which call PDF-processing code where shown. Major documented capabilities are retained, including tools whose implementations were not sampled. Edges are limited to README statements and source-index references; unsampled tool internals are not inferred.

Main entry points: [`src/App.tsx`](https://github.com/vovalitwinov2012-wq/all-pdf/blob/main/src/App.tsx) (Routed application), [`src/features/pdf-core/pdfOps.ts`](https://github.com/vovalitwinov2012-wq/all-pdf/blob/main/src/features/pdf-core/pdfOps.ts) (PDF operations), [`src/pages/tools/SignPage.tsx`](https://github.com/vovalitwinov2012-wq/all-pdf/blob/main/src/pages/tools/SignPage.tsx) (Sign documents), [`src/pages/tools/MergePage.tsx`](https://github.com/vovalitwinov2012-wq/all-pdf/blob/main/src/pages/tools/MergePage.tsx) (Merge and images to PDF)
