Before / After - owl, 2× with face restoration
Batch-upscale a whole folder at once, up to 10× - to exact print sizes at 300 DPI, entirely on your own NVIDIA GPU. No uploads, no accounts, no slow cloud queue.
No frills, no fluff - just a fast, local batch image upscaler for Windows that turns low-res art into print-ready files on your own NVIDIA GPU. Six things that matter, when each one matters.
FP16, TF32, torch.compile, 768-pixel tiles. A 4K upscale of a 1080p mockup finishes in about eight seconds on an RTX 3060 Ti.
Drop a folder, set the scale, get an archive back. No limits, no babysitting individual files.
A smooth slider, not three preset buttons. Hit exact print dimensions every time.
The alpha channel runs through the model on its own. No serrated edges on transparent PNGs.
Nothing uploads. Or, if you'd rather, use the optional cloud press with your own Replicate key.
Pick by intent, not by filename. Low Resolution for compressed source, CGI / Anime for digital art, High Fidelity for grain-preserving photo work - each backed by a different ESRGAN weight.
Pick a poster size in inches (5×7 up to 24×36, plus A2 / A1). The output lands at the exact pixel count for the chosen DPI, with the print-DPI tag written into the file so Etsy and Redbubble accept it on first upload.

AI Upscaler Studio needs an NVIDIA GPU to press at the speed it's built for. If you don't have one, please read this before buying.
Windows: Press Win + X → Device Manager → expand Display adapters. If you see "NVIDIA GeForce …" you're good. If you see "AMD Radeon", "Intel UHD/Iris/Arc", or only one entry that isn't NVIDIA - AI Upscaler Studio will run on CPU and be slow. Stick with cloud-only tools or use the Replicate fallback.
Faster check: Press Ctrl + Shift + Esc → Performance tab. Each GPU on your machine is listed in the left sidebar.
A one-time-purchase image upscaler with no subscription - lifetime licence, no upsells, no expiry.
LAUNCH at checkout.If yours isn't here, send us a message and we'll get back to you.
Your licence covers 3 machine activations - install and activate AI Upscaler Studio on up to three of your own computers. Batch size is unlimited, so you can drop a whole folder and walk away. Need more than three seats? Email support and we'll sort it out.
Windows 10 or 11 with an NVIDIA GPU that has at least 4 GB of VRAM (RTX 2060 and up recommended). No GPU? Use the built-in Replicate cloud option with your own free API key - you pay per image, but you skip the hardware.
Yes - outputs are yours. The AI Upscaler Studio license covers personal, freelance, and commercial use on the activated machine, including selling prints on Etsy, POD platforms, and your own shop.
Topaz is the premium player at $99+ and is excellent. AI Upscaler Studio is faster on batch jobs, costs about half as much, runs as a local web app instead of a heavy desktop binary, and handles transparent PNGs more cleanly. Topaz is better for single-image, fine-tuned photographic work.
No. One-time purchase, lifetime use, free minor updates. Major version upgrades (e.g. AI Upscaler Studio 3.0 with video) will be optional and discounted for existing customers.
Yes - Real-ESRGAN, the same family of model used in many commercial tools, running locally on your GPU. Three distinct pretrained weights are bundled, each chosen by intent: Low Resolution (RealESRGAN x4plus) for compressed source, CGI / Anime (x4plus_anime_6B) for digital art, and High Fidelity (RealESRNet x4plus) for photo work where grain and texture matter more than maximal sharpness. All open-source - Real-ESRGAN trains on synthetic degradation rather than scraped image sets, so there's no training-data licensing trouble.

Windows only at launch. Mac and Linux are on the roadmap if there's enough demand to justify the port.
