1. 将图片用PS打开。
2. 快捷键Ctrl+Shift+Alt+S

品质越小，图片占的内存就越小，但是图片的清晰度就会越低

清除图片冗余，

1.将以下代码放在txt文档，然后改后缀jsx格式

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();
