# issuu2epub
|

# Issuu to EPUB Converter
|
||||
|
||||
Download Documents from Issuu as EPUB Files.
|
||||
Ein Python-Skript zum Konvertieren von Issuu-Dokumenten in EPUB-Dateien,
|
||||
optimiert für Kindle E-Reader.
|
||||
|
||||
## 📋 Übersicht
|
||||
|
||||
Dieses Tool lädt Dokumente von Issuu herunter und konvertiert sie in das
|
||||
EPUB-Format. Das erste Bild wird als Cover verwendet, und alle Bilder werden für
|
||||
optimale Darstellung auf E-Readern komprimiert.
|
||||
|
||||
## ✨ Features
|
||||
|
||||
- **Einfache Befehlszeilenschnittstelle** mit Click
|
||||
- **Automatisches Cover** aus der ersten Seite
|
||||
- **Kindle-optimierte** Bildkompression
|
||||
- **Kein Inhaltsverzeichnis** für direkten Zugriff auf den Inhalt
|
||||
- **Temporäre Verzeichnisse** für saubere Verarbeitung
|
||||
- **Unterstützt große Dokumente** mit Stream-Download
|
||||
|
||||
## 🚀 Verwendung
|
||||
|
||||
### Einfache Verwendung
|
||||
|
||||
```bash
|
||||
python issuu2epub.py
|
||||
```
|
||||
|
||||
Das Skript fragt interaktiv nach allen benötigten Informationen:
|
||||
|
||||
1. Issuu URL: Die URL des Issuu-Dokuments
|
||||
2. Document Title: Titel des Dokuments
|
||||
3. Document Author: Autor des Dokuments
|
||||
4. EPUB Output Filename: Name der Ausgabedatei (z.B. mein_dokument.epub)
|
||||
|
||||
### Direkte Befehlszeilenverwendung
|
||||
|
||||
```bash
|
||||
python issuu2epub.py --url "https://issuu.com/bscyb1898/docs/yb_mag_nr._1_saison_2025_26" --title "YB Mag 2025 01" --author "BSC YB" --output "YB_Mag_2025_01.epub"
|
||||
```

||||
