Antelope 3.2
Compress JPGs/ PNGs without losing quality

Antelope is a tool for reducing the size of JPG and PNG files, without apparently affecting the images.

The program supports lossless compression, which doesn't affect image quality, or you can enable lossy compression for greater reductions in file size.

By default the program will overwrite your source files, so be extremely careful. Ideally, always work with copies. Otherwise, open the Options dialog and check "Backup original file".

Once you understand that key detail, basic operation is easy - just drag and drop your images onto the Antelope window and click Compress. The program then uses OptiPNG and JPEGTran to apply lossless compression to your images, reporting any file size reductions as it works. Results vary depending on your source images, but will typically be very small, just a percentage point or two.

If you'd like to improve PNG compression then setting Antelope's "Optimization Factor" to "Max" may help, though beware: it also significantly increases the time the process takes (a single large image might require a minute or more). If you need to compress lots of very large images then test this setting with just one, first.

Antelope also provides separate "Lossy Mode" settings for both PNG and JPGs, and enabling this can produce spectacular reductions (our test PNG file sizes routinely fell by 60% or more). But the program is taking drastic action to achieve this - like reducing PNGs to 256 colours - and while it's doing so in an intelligent way, you may well find the loss in image quality is too great.

One additional problem is that there's no setting to define how lossy your JPEG compression will be, unfortunately. This isn't a massive issue - the default isn't too drastic - but it's still something the user should be able to decide.

Verdict:

Antelope needs work. The default settings aren't always ideal (it really shouldn't overwrite source files), and users should have more control over what it does. The program really can cut the size of your JPGs and PNGs, though, and as long as you remember to work with copies only, it's worth a closer look.

Ashampoo Burning Studio 2013 (v11.0.6)

Free Full Commercial Software

Ashampoo Burning Studio 2013 is a compact, simple, but surprisingly feature-packed disc burning suite.

The program makes it easy to create simple data discs and audio CDs, for instance: just drag and drop your files onto the list area and you'll be burning the finished disc in a couple of clicks.

That's just the start, though. Burning Studio 2013 can also create data discs with customised, interactive multi-page menus, perfect if you'd like a more professional way to share and present the disc contents.

A built-in backup tool allows you to create backups which may be encrypted, compressed, and span several CDs, DVDs and Blu-rays.

And there are modules to create VCD or SVCD video projects; burn video DVDs or Blu-ray discs from prepared folders; create, browse or burn disc images (ISO, CUE/ BIN and Ashdisc formats are supported); copy discs, erase them, design and print disc covers, labels and booklets, and more.

The focus throughout is on ease of use, though, and so Ashampoo Burning Studio 2013 remains very straightforward, whatever you're doing. Most disc projects are created via the same simple interface, and for the most part all you have to do is drag and drop the necessary files. But experts will find more advanced options are only a click away, and if you need to then you can set ISO and UDF version, enable Joliet, make a disc bootable and more.

Note the download here will take you to the Downloadcrew Software Store where you can download Burning Studio 2013.
