Решение Adobe Photoshop для форматирования файлов
API High Code и бесплатные приложения для PSD, PSB с возможностью уменьшения размера файлов и сжатия с использованием недокументированных возможностей
Бесплатное онлайн-приложение к Compress PSD и уменьшение его размера
Сжимайте большие файлы PSD и PSB, используя методы с потерями и без потерь. Откройте для себя скрытый потенциал Aspose.PSD. Это не всегда безопасно для данных в PSD-файле, поэтому, если вы часто его используете, вам следует протестировать PSD-файлы после сжатия. Обратите внимание, что некоторые функции сжатия работают с потерями, поэтому после такого сжатия вы не сможете восстановить исходные PSD-файлы. Эта функция предоставляется «как есть». Можно сжать PSD или уменьшить размер файлов PSB.
