LeptonGUI
Compress JPGs by 20% or more

Disclosure: LeptonGUI is a tool I've developed. That makes it difficult for me to be unbiased, and so I'll tell you what the program does, but not try to assess how well it does it.

Lepton is an open-sourced Dropbox technology for the lossless compression of JPEGs.

The program can compress JPG files by 20% or more, exporting the results in a LEP format (picture.jpg > picture.lep). Point the program at LEP files later and it restores the original JPG file, byte for byte.

The standard Lepton.exe runs only from the command line, and can behave strangely if you don't run it in just the right way. Experienced users won't have any trouble with it, but we've also put together a very basic front end that might be easier to use.

Operations are much like any other conversion tool. Drag and drop your source files, JPG or LEP, or click Open and choose whatever you need, and click Convert to process them (JPGs become LEP, LEPs are restored to JPG).

The program won't overwrite the destination file. This is intentional, as I don't completely trust Lepton to work in all circumstances, and I don't want there to be any risk of losing data.

When you're done, LeptonGUI displays the individual savings for each file and the overall compression rate.

Verdict:

LeptonGUI is a very basic front end for Lepton, but it doesn't add any other functionality. Try it if you'd like to add drag and drop support, otherwise stick with the command line build.

WhatsApp Messenger 2.19.20

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

What's New in Version 2.19.20 

• You can now reply to a group message privately in your 1:1 chat. Tap and hold a message in a group chat and select "More", then "Reply Privately".
• When editing a photo or video, you can tap the smiley icon to add stickers. 
• From the Status tab, you can now 3D touch to preview a contact's status.
