@@ -32,14 +32,13 @@ Die Batch lädt bei Bedarf automatisch das **Windows Embeddable Python Package**

 ## Was das Tool macht
 - Entpackt die PPTX in einen Temp‑Ordner
- Komprimiert **JPG/JPEG, PNG, WebP** mit **CaesiumCLT** (Default `-q 90`, `-O bigger`)
+- Komprimiert **JPG/JPEG, PNG, WebP, GIF** mit **CaesiumCLT** (Default `-q 90`, `-O bigger`)
 - Ersetzt Bilder nur, wenn die komprimierte Datei kleiner ist
 - Schreibt ein CSV‑Log (`.log` neben der Output‑PPTX)
 - Baut eine neue PPTX und zeigt eine Summary (Name, Größe vorher/nachher, Ersparnis %, Zeit)
 - Räumt alle temporären Dateien auf (keine Caesium‑Tempfiles in der finalen PPTX)

 ## Hinweise
- **GIF** wird übersprungen (keine Rekodierung).
 - `-t` steuert die Parallelität der Python‑Threads; intern wird `caesiumclt --threads 1` gesetzt, sobald `-t > 1`, um Oversubscription zu vermeiden. Default ist 16
 -  `-q` steuert das Qualitätslevel; intern wird `caesiumclt -q` mit diesem Wert von `0..100` benutzt, Default ist 90
 - Die Batch **verwendet bevorzugt das Embeddable Python** neben der BAT; ansonsten sucht sie echte `python.exe`/`py.exe` im PATH, **ignoriert** aber die Microsoft‑Store‑Alias‑Pfade (`WindowsApps`).
