Desktop applications require Windows 10 or later with 4GB RAM minimum. Browser-based tools work on any modern browser including Chrome, Firefox, Safari, and Edge. No additional software installation required for web tools.

Our tools support all major formats: JPEG, PNG, WEBP, PDF, MP4, AVI, SRT, VTT, and more. Maximum file size is 500MB for desktop tools and 100MB for browser tools. Batch processing supports up to 1000 files simultaneously on desktop applications.

All paid tools include full commercial usage rights with no attribution required. Free browser tools are for personal and commercial use.

Processing speed depends on file size and system specifications. Desktop tools utilize local hardware for maximum speed. Browser tools process files locally in your browser for privacy and security - no uploads to external servers required.

If you purchased an existing desktop software, downloads are delivered within 24 hours via email. Check your spam folder if you don't receive it.

Browser tools are instantly accessible after purchase. All products (except custom software OR products that require an internet connection) are DRM-free.

If you requested custom software, you will receive the access through the contact information provided.

If you requested flash (quick delivery) custom software, you will receive the access through the contact information provided within 24 hours.

Our software is digitally signed and safe. If Windows Defender flags the application, temporarily disable real-time protection during installation or add an exclusion for the download folder. This is common with automation tools and does not indicate malware.

Due to the DRM-free nature of our software, refunds are evaluated case-by-case. We cannot process refunds for change of mind or misread product descriptions. Technical issues preventing software use may qualify for refund. Contact contact@nxlibrary.com with your purchase details.

Your business information and project details are securely stored in our encrypted systems. We maintain strict confidentiality for all client data and never share proprietary information with third parties. Your data remains protected throughout our partnership.
