完美解决Photoshop导出的 jpg 图片很大的问题

1、这代码复制到文本里，后缀名为.jsx 文件

function deleteDocumentAncestorsMetadata() {

whatApp = String(app.name);//String version of the app name

if(whatApp.search("Photoshop") > 0) { //Check for photoshop specifically, or this will cause errors

//Function Scrubs Document Ancestors from Files

if(!documents.length) {

alert("There are no open documents. Please open a file to run this script.")

return;

}

if (ExternalObject.AdobeXMPScript == undefined) ExternalObject.AdobeXMPScript = new ExternalObject("lib:AdobeXMPScript");

var xmp = new XMPMeta( activeDocument.xmpMetadata.rawData);

// Begone foul Document Ancestors!

xmp.deleteProperty(XMPConst.NS_PHOTOSHOP, "DocumentAncestors");

app.activeDocument.xmpMetadata.rawData = xmp.serialize();

}

}

//Now run the function to remove the document ancestors

deleteDocumentAncestorsMetadata();

2、到PS里打开那个大文件

3、文件菜单，脚本，浏览，选择这个.jsx文件

4、最后保存一下试试 是不是解决问题了
