How Image Upscale Works
Image Upscale uses AI super-resolution to increase image dimensions by 2x or 4x while generating genuine detail that simple scaling cannot produce. The AI model has been trained on millions of images and predicts the fine textures, edges, and details that would exist at higher resolution. Two quality tiers are available: fast mode for quick previews and HD mode for maximum detail recovery.
Photographers use Image Upscale to prepare images for large-format printing. E-commerce sellers enlarge product photos for zoom views on product pages. Designers upscale stock imagery or legacy assets to meet modern resolution requirements. Archive and restoration projects recover detail from low-resolution scans.
Start with the highest quality source file you have -- upscaling works best with clean, minimally compressed originals. JPEG compression artifacts tend to be amplified by upscaling, so use PNG or high-quality JPEG sources when possible. The fast tier is suitable for web use, while HD mode is recommended for print production. At $0.001-0.03 per image, upscaling is one of the most affordable operations on the platform.

No. FairStack uses pay-per-use pricing. Add funds to your account and use any tool whenever you need it. There is no subscription, no monthly commitment, and no minimum spend.
What file formats does Image Upscale support?
Image Upscale outputs PNG, JPG, and WebP. You can download results instantly after generation. All outputs are full quality with no watermarks.
How long does Image Upscale take?
Most generations complete in 2-10 seconds. Processing time depends on the complexity of your input and the selected quality settings. You can monitor progress in real time.
Can I use Image Upscale outputs commercially?
Yes. All outputs generated on FairStack include a commercial-use license. You can use them in client work, products, marketing materials, social media, and any other commercial context.
What is the maximum output resolution for Image Upscale?
At 4x upscale, a 1024x1024 input becomes 4096x4096 -- suitable for large-format prints. Output format is PNG for maximum quality. The AI generates real detail (textures, edges, text sharpening), not just interpolated pixels.
Can I use upscaled images for print production and commercial projects?
Yes. All FairStack outputs include a commercial-use license. Upscaled images can be used for print production, large-format displays, product photography, marketing materials, and any other commercial purpose.
Can I upscale images in bulk?
The web app processes one image at a time. For bulk upscaling, use the FairStack API to submit multiple images for parallel processing. At $0.001-0.03 each, upscaling 100 images costs as little as $0.10.
