Adobe® Photoshop®-Dateiformatlösung

High-Code-APIs und kostenlose Apps für PSD, PSB mit der Möglichkeit, die Größe von Dateien zu reduzieren und mithilfe undokumentierter Möglichkeiten zu komprimieren

Größe von PSD-Dateien reduzieren

Die Größe großer PSD-Dateien zu reduzieren ist ein einfacher Vorgang, wenn Sie Aspose.PSD verwenden. Eine Reduzierung der Größe kann erreicht werden, indem Cache-Daten aus PSD-Dateien entfernt, Ebenen zusammengeführt und in das PSD-Format konvertiert werden, wobei weniger Bit pro Farbe verwendet wird. Sie können auch den Farbmodus der PSD-Datei ändern. Wenn Sie beispielsweise von CMYK-Farbe zu RGBA-Farbe wechseln, wird die PSD-Dateigröße reduziert. Diese App verwendete nicht dokumentierte Funktionen des PSD-Formats, sodass das Endergebnis beeinträchtigt werden kann. Bitte verwenden Sie PSD File Reduce nur, wenn Sie wissen, was Sie archivieren möchten.
