Skip the ComfyUI upscale nodes and Automatic1111 hires.fix complexity. PixelMax upscales your Stable Diffusion images to 4K using Real-ESRGAN AI — just drag, drop, and download in 30 seconds. $1 per image.
Upscale Your SD Image →The fastest path from SD output to print-ready resolution.
Forget installing ComfyUI upscale nodes, configuring ESRGAN models in Automatic1111, or fighting with VRAM errors. PixelMax runs in the cloud — any browser, any device, zero configuration.
PixelMax uses the same Real-ESRGAN architecture that SD users install locally — but hosted in the cloud. You get identical 4× upscaling quality without managing Python environments or downloading model weights.
Topaz Gigapixel costs $199/year and needs a powerful GPU. PixelMax is $1 per image with no subscription. Perfect for SD artists who don't want another software license.
Three steps. Thirty seconds. No installs.
Create your image in Automatic1111, ComfyUI, or any SD interface. Generate at your preferred resolution — PixelMax handles the upscaling.
Drag and drop your SD output into PixelMax. Select 4× upscale. No model downloads, no VRAM requirements — it runs in the cloud.
Your image is upscaled to 4× resolution in about 30 seconds. A 512×512 image becomes 2048×2048; a 1024×1024 becomes 4096×4096.
Everything SD users ask about PixelMax.
Hires.fix in Automatic1111 re-runs the diffusion process at higher resolution, which can change your image's composition. PixelMax uses Real-ESRGAN post-processing — it upscales exactly what you generated without altering the content. It's also dramatically simpler to use.
No. PixelMax runs entirely in the cloud. You just need a web browser. This is especially useful for SD users on laptops or machines with limited VRAM who can't run local upscaling models.
SD 1.5 defaults to 512×512, SDXL outputs at 1024×1024, and custom workflows vary. All of these are too small for quality printing at 300 DPI. PixelMax 4× upscale takes any SD output to print-ready resolution.
PixelMax is $1 per upscaled image. No subscription, no software license. Compare to Topaz Gigapixel at $199/year or running your own ESRGAN setup with GPU costs.
Yes. PixelMax supports batch processing — upload multiple images and upscale them all in parallel. Perfect for SD users generating variations who need all outputs at high resolution.
Cloud-powered Real-ESRGAN upscaling for your Stable Diffusion art. $1 per image.
