batch export to filesize

[getho]

image processor is rubbish

image processor pro needs a load of faff to get it working

you cant include photoshop 2021 export in an action

this is pathetic!

How can this now be worse than it was 10 years ago?

Any suggestions for an alternative way to do this?

I'm not sure if it is worse, however, it is no better in this aspect. 😐

There are some custom scripts to save a file to a targeted file size on disk. I don't believe that they are specifically designed for batching, so it remains to be seen how well they would perform when recorded into an action and used with Batch, Image Processor, Image Processor or Picture Processor scripts.

Further code could be added for a custom bulk process.

I'll have to dig up these scripts for you... to be continued!

There is an error on line 28, however, I'm, not sure what the fix is:

jpegQuality = jpegQuality – dec;

Full code:

var doc = app.activeDocument;
var filename = doc.name;
var foldername = doc.path.name;
var filepath = doc.path;
var parentfilepath = doc.path.parent
var jpegQuality = 70; // desired quality
var maxfilesize = 512000; // max size in bytes
var dec = 5; // decreasing step
var minimumqual = 50; //minumum desired quality
savefolder = new Folder(filepath + '/BATCH/');
savefolder.create();
saveFile = new File(savefolder + '/' + filename.split('.').slice(0, -1).join('.') + ".jpg");
doc.flatten();
doc.pathItems.removeAll();
doc.channels.removeAll();

function savebatchweb(saveFile, jpegQuality) {
    var sfwOptions = new ExportOptionsSaveForWeb();
    sfwOptions.format = SaveDocumentType.JPEG;
    sfwOptions.includeProfile = true;
    sfwOptions.interlaced = 0;
    sfwOptions.optimized = true;
    sfwOptions.quality = jpegQuality;
    doc.exportDocument(saveFile, ExportType.SAVEFORWEB, sfwOptions);
}
savebatchweb(saveFile, jpegQuality);
while (saveFile.length > maxfilesize) {
    jpegQuality = jpegQuality – dec;
    saveFile = new File(saveFile);
    saveFile.remove();
    savebatchweb(saveFile, jpegQuality);
    if (jpegQuality <= minimumqual) {
        break
    }
}
doc.close(SaveOptions.DONOTSAVECHANGES); //closes file
