What it does
BulkPro AI Image Upscaler enlarges low-resolution images with AI. Unlike plain resizing, it reconstructs missing pixels intelligently instead of blurring.

Frequently asked questions
How do I enlarge an image without losing quality?
Pick a scale factor (2x-4x) and an AI engine, then run; the tool reconstructs missing pixels instead of blurring them.
Do I need an internet connection?
Only the first run downloads a small AI model (about 1-5 MB). Later runs work fully offline.
Are my images uploaded to the cloud?
No. Upscaling runs on your computer, GPU-accelerated; your images are never sent to any server.
