Image Enlarger HQ Batch adds powerful batching tools to the popular Image Enlarger HQ image enlarger. You can now apply the best available upscaling algorithms to large numbers of images automatically while maintaining exact control of quality.

Image Enlarger HQ Batch gives you the tools you need to extract the most quality possible out of image enlargements.

Setup in a proven workflow that allows you to apply pre-blurring, an advanced interpolation algorithm followed by optional sharpening (unsharp mask), this application gives high quality enlargement results.

The application includes 20 interpolation algorithms giving you tools for a variety of image types. Whether you're upsizing a portrait, a line drawing or pixel art, the included algorithms will allow for best-case results for each.

Optionally converting to and from linear colorspace allows for better color retention through the enlarging process.

For special case use the application allows for changing an enlarged image's aspect ratio.

The application supports large images (though maximum image size will depend upon the host computer's available resources). Maximum image size can be set in the application's preferences.

The application supports opening and saving in a variety for image formats. Image formats supported:

Photoshop, PDF
Microsoft Icon, Microsoft BMP

Important elements missing, at least for me

On my iMac 3.06 Ghz, the scroll bars keep disappearing, so a graphic larger than the window it occupies is hard to move - no hand tool or zoom out capability available, either. Also, I can't find a way to preview the graphic to see what the parameters I'm choosing will look like in the enlargement, which renders me handicapped until the final product is rendered - a bit like an archer required to aim at his target blindfolded. Unlike some other reviewers here, conversely, I thought the upscaled pics were good - albeit purely accidental without a preview. So, while the app has potential in its current price range, I'll stick with more expensive enlargement programs that provide basic and critical control until updates by this programmer stop forcing me to work in the dark. Hand tool, zoom button, preview window. Oh, yeah!


I got so annoyed at trying to enlarge images one-by-one in another app that I almost threw my Mac out of the window. Such a relief to finally get this app out as I can now set everything up in a few clicks, then go off and do something else. Then, when I return, it's all done, I've not had any error messages. So great to finally get that time back so I don't have to waste hours of justing clicking now. I think the quality is actually quite good, certainly it's worth it for the amount of time that it takes. You'd be amazed at how quick it is, and once you've used this, you won't be able to use another app, so that shows how good this one really is.


The only thing that puts me off this app is the price. It's good if you're going to be using it a lot, but this app is so good that I want everybody to buy it, because it beats all of the other apps that don't have the batch system. It seems so simple, but most other apps don't have it, so that's definately a reason to get this app.
