How about a script?
copy this script to your scripts folder (extension should be *.jsx)
If "saving as a PNG" is the only function you want to include in your action, you can also assign a shortcut to your script.
You can also integrate the script into your action.
[CODE=javascript]#target photoshop
(function () {
if (app.documents.length === 0) {
alert("No document open.");
return;
}
var doc = app.activeDocument;
// Derive file name and target path
var nameNoExt = doc.name.replace(/\.[^\.]+$/, ""); // remove extension
var extension = doc.name.split('.').pop().toLowerCase();
if (extension === "png") {
alert("This document is already a PNG. Saving would overwrite the original. Operation cancelled.");
return;
}
var targetFolder = doc.fullName.parent;
var targetFile = new File(targetFolder + "/" + nameNoExt + ".png");
// Overwrite if it already exists
if (targetFile.exists) {
try {
targetFile.remove();
} catch (e) {
alert("Failed to remove existing file:\n" + e);
return;
}
}
// PNG save options – moderate optimization (compression 6 of 0–9)
var pngOpts = new PNGSaveOptions();
pngOpts.compression = 6; // 0 (none) … 9 (max) – 6 ≈ moderate
pngOpts.interlaced = false; // no interlacing
// Make sure profile is NOT embedded
if (pngOpts.hasOwnProperty('embedColorProfile')) {
pngOpts.embedColorProfile = false;
}
// Save with lower‑case extension
doc.saveAs(targetFile, pngOpts, true /*asCopy*/, Extension.LOWERCASE);
// Done
})();[/CODE]
