I have a lot of .ai files with logo and I need to export them into PNG files. Is there an antomatic way of doing it? I know you cannot record the export part in Action...

    Hi,

    You can use following snippet for your documents. When you run the script it will ask for the folder where source file exists. So select source_files folder in your case and png will be exported at the Desktop.

     

    var _folder = Folder.selectDialog();
if (_folder != null) {
    var _files = _folder.getFiles('*.ai');
    for (var f = 0; f < _files.length; f++) {
        var doc = app.open(_files[f]);
        var docAssets = doc.assets;
        var assetIDArray = new Array();
        var itemToExport = new ExportForScreensItemToExport();
        itemToExport.artboards = '';
        itemToExport.document = false;
        var assetArray = new Array();
        var _layer = doc.layers[0];
        for (var i = 0; i < _layer.groupItems.length; i++) {
            var asset = docAssets.add(doc.groupItems[i]);
            assetIDArray.push(asset.assetID);
        }
        itemToExport.assets = assetIDArray;
        var options = new ExportForScreensOptionsPNG24();
        app.activeDocument.exportForScreens(File('~/Desktop'), ExportForScreensType.SE_PNG24, options, itemToExport);
    }
}

    that is what I'm doing for the moment. The painful things is to open up hundreds of .ai files one by one, export them as multiple assets, and close them one by one. 

    I think there is a way to speed it up by using scrips since I only need to open a file and export them to png, right?

    Hi,

    Yes this possible via script. I have simple script that exports all selected items of the active document as PNG, but this can be modified to run on all multiple documents.

    My question, is do you want to export all items inside all documents or some specific? Coudl you share some ai sample files

     

    Below is sample script

    var doc = app.activeDocument;
var docAssets = doc.assets;
var assetIDArray = new Array();
var itemToExport = new ExportForScreensItemToExport();
itemToExport.artboards = '';
itemToExport.document = false;
var assetArray = new Array();
for (var i = 0; i < app.selection.length; i++) {
    var asset = docAssets.add(app.selection[i]);
    assetIDArray.push(asset.assetID);
}
itemToExport.assets = assetIDArray;
var options = new ExportForScreensOptionsPNG24();
app.activeDocument.exportForScreens(File('~/Desktop'), ExportForScreensType.SE_PNG24, options, itemToExport);

     

    NOTE: This will export only selected items of the active document. if you answer above quetsion, we can help you in right direction.

    Best regards
