Gigapixel AI Image Upscaler — Frequently Asked Questions

Everything you need to know about our AI upscaling tool

What is Gigapixel AI image upscaling?
Gigapixel AI uses deep-learning to enhance images while reconstructing fine detail at the pixel level. Unlike traditional bicubic resampling — which blurs edges — our model intelligently predicts missing pixels, producing naturally sharp results at up to 4K resolution.
What image formats does it support?
Upload JPG, PNG, or WEBP files up to 10 MB. Export as JPG (smallest size), PNG (lossless), or WEBP (modern compression). Works for web, print, and archival.
How much does Gigapixel AI upscaling cost?
Free to try. Upload your image, pick a resolution, and download the result — no account, no credit card, no watermarks on your output.
What output resolutions are available?
Gigapixel AI supports 1K, 2K, and 4K output resolutions. 4K delivers ultra-high-definition results suitable for large-format printing and professional use.
Is my image data private?
Yes. Images are processed securely via API and are not permanently stored, shared, or used for any other purpose.
How is this different from Topaz Gigapixel AI?
Topaz is a desktop app requiring installation and a paid license. Our Gigapixel AI tool delivers the same class of AI enhancement directly in your browser — no install, no subscription, accessible on any device.
