Secure compression

Compress PDFs offline so they don't leave your system, maintaining your file security.

I use it to compress PDF medical Endoscopy etc. reports generated on Meditech Expanse prior to uploading to my EMR. The size post-compression is similar to or smaller than the same copy faxed!

PROS:

  1. Offline (for medical reports that's mandatory)

  2. Conscionable pricing

  3. Based on my subjective impression: the post-compression photos in the PDF seem "lossless" in quality.

  4. Batch processing.

  • Yes, we offer a fully functional 14-day free trial without any sign-up. Once installed, your trial will be automatically activated, and it'll work just like the full software without adding any watermarks.

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

    NXPowerLite 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.
