Geben Sie die Zielbreite und -höhe in die Formulareingaben ein, laden Sie die Stapelwarteschlange und laden Sie das Zip-Paket herunter.

„Fit Inside“ bewahrt den gesamten Bildinhalt. „Auf Füllung zuschneiden“ beschneidet die Ränder, um zu verhindern, dass Layouts gequetscht werden.

Ja, entsperren Sie den Seitenverhältnis-Schalter, um Breite und Höhe separat zu skalieren (Hinweis: Das Bild kann gedehnt werden).

Nein, die Verarbeitung erfolgt im lokalen Sandbox-Speicher. Es findet kein Internet-Upload des Bildes statt.

Nein, es sind keine Cloud-Speicherintegrationen oder Netzwerkübertragungen verbunden, sodass die Dateien sicher bleiben.

Der clientseitige Canvas-Export erstellt eine saubere Rasterausgabe, bei der standardmäßig die Details der alten Metadaten entfernt werden.

Beim Strecken kleinerer Bilder tritt Unschärfe auf. Gestreckte Formen treten auf, wenn die Seitenverhältnisse entsperrt sind.

Die Beschränkungen hängen von der Browser-Canvas-Zuweisung ab (normalerweise bis zu 16.000 x 16.000 Pixel bei Desktop-Browsern).

Stellen Sie sicher, dass das Dropdown-Menü für das Ausgabeformat auf PNG eingestellt ist. JPG unterstützt keine Alphakanal-Transparenz.
