Once installed, your trial will be automatically activated, and it'll work just like the full software without adding any watermarks. The only limitation is a batch size of 20 files, compared to the 10,000 files that the paid version can compress.

  • NXPowerLite Desktop costs just $57 one-off cost for a single user.

    NXPowerLite Desktop is licensed per user rather than per machine, so if you buy a license you can install it on up to 3 machines so long as you are the only user of the software.

    Licenses are perpetual, so they don't expire. Once you buy a license you can use that major version of the software for as long as you want without paying additional fees.

    Volume discounts start at 10 users, so the more licences you buy the less you pay per user. Visit our support site for more information on multi-user licensing.

    If you work at a non-profit then simply email us with your work email address to verify your details and we will send you a discount code.

  • NXPowerLite Server costs from $257/ yr per server, depending on the storage capacity.

I have used various online PDF tools to compress files, but I needed a more convenient and secure way to compress multiple PDF files. I found the free version of NXPowerLite Desktop and have not been disappointed ... It performs really well and I also discovered an Outlook add-in to automatically compress email attachments. I am over the moon. Good job guys!
