AI Image Upscaler
Enlarge any image up to 16K without losing detail. Powered by Topaz — the industry standard for professional AI upscaling, now in your browser.
Keyo Studio's AI image upscaler takes any photo, illustration, or AI-generated image and enlarges it to a higher resolution while rebuilding the detail that low-resolution files normally lose. Powered by Topaz — the de facto standard for professional-grade AI photo enhancement — it brings desktop-grade upscaling quality into the browser, with no software to install and no technical knowledge required. You upload your image, choose your target resolution, and the model reconstructs sharp textures, clean edges, and fine detail at up to 16K output. Whether you're preparing an image for large-format print, recovering a compressed photo, or taking an AI-generated image to production quality, the result is ready to download in minutes.
How AI image upscaling works
Traditional upscaling stretches pixels, producing blurry, soft results that look worse the larger you go. AI upscaling works differently: the model analyzes the content of your image — textures, edges, faces, structure — and reconstructs the missing detail rather than stretching what's already there. Topaz's upscaling models enlarge images with invented but believable detail, useful for printing large from a small original or recovering a compressed file to full resolution. The result is a larger image that looks genuinely sharp, not a blurry one that's been stretched.
Up to 16K output, five resolution tiers
Keyo Studio's image upscaler outputs at five resolution tiers based on the longest side of your image: 1K, 2K, 4K, 8K, and 16K. The model preserves your original aspect ratio throughout, so portrait and landscape images both come out correctly proportioned at any size. At 16K, the output is large enough for billboard printing, large-format display, and any professional production use case that demands the highest possible resolution. You pay per output resolution — not per megapixel, not per processing minute — so cost is predictable at every size.
Powered by Topaz: the professional standard
Topaz Labs has been building AI image enhancement tools since 2015, and their upscaling models are used by landscape, wildlife, wedding, and commercial photographers as the benchmark for quality. Their model lineup includes specialized tools for different image types — High Fidelity V2 for high-resolution inputs like smartphone photos and RAW files, Standard V2 for general detail and sharpness improvement, Low Resolution V2 for heavily compressed or very small originals, CGI for digital illustrations and computer-generated artwork, Text Refine for images with typography, Recovery and Recovery V2 for rebuilding lost detail, and Wonder for one-click sharpen, upscale, and denoise in a single pass. Each model is trained on a specific type of content, so the reconstruction is matched to what your image actually contains.
What you can upscale
The AI image upscaler handles any type of image: photographs from any camera or phone, AI-generated images from any model, product shots, illustrations and artwork, scanned documents and archive photos, and screenshots. It works particularly well on AI-generated content — taking an image produced at lower resolution on Keyo Studio and rendering it at print quality in the same platform, without switching tools. Topaz's specialized models are trained on different image types, lighting, and noise profiles, so the result stays true to the original no matter what kind of image you're working with.
Pricing on Keyo Studio
Image upscaling is priced by output resolution tier: 1 credit for 1K, 1 credit for 2K, 3 credits for 4K, 6 credits for 8K, and 12 credits for 16K. Cost is fixed per output size — you know exactly what you'll spend before you generate. Credits are shared across every tool on the platform, so you can move between image generation, video creation, and upscaling without managing separate accounts or subscriptions.
Why Keyo Studio
Professional AI upscaling used to mean installing desktop software, managing licenses, and processing files locally. Keyo Studio brings Topaz's professional models into the browser — same quality, no installation, no subscription to a separate tool. Upload from anywhere, upscale to any resolution, download and use. And because it's part of the same platform as your image and video generation, you can go from generating an image to upscaling it to production quality without ever leaving your workflow.

What is an AI image upscaler?
An AI image upscaler enlarges an image to a higher resolution while rebuilding the detail that low-resolution files normally lose. Unlike traditional upscaling, which simply stretches pixels, AI upscaling reconstructs textures, edges, and fine detail to produce a genuinely sharp larger image.
How high can I upscale an image on Keyo Studio?
Keyo Studio's AI image upscaler outputs up to 16K resolution based on the longest side of your image, across five tiers: 1K, 2K, 4K, 8K, and 16K. Aspect ratio is preserved automatically at every size.
What AI models power the image upscaler?
The upscaler is powered by Topaz — the industry standard for professional AI photo enhancement. Available models include Standard V2, High Fidelity V2, Low Resolution V2, CGI, Text Refine, Recovery, Recovery V2, Redefine, Standard MAX, and Wonder, each trained for a specific type of image content.
Which Topaz model should I use?
Use High Fidelity V2 for high-resolution inputs like photos and RAW files, Standard V2 for general upscaling, Low Resolution V2 for heavily compressed or very small images, CGI for illustrations and digital artwork, Text Refine for images with typography, and Wonder for a one-click sharpen, upscale, and denoise in a single pass.
How much does AI image upscaling cost on Keyo Studio?
Image upscaling is priced by output resolution: 1 credit for 1K, 1 credit for 2K, 3 credits for 4K, 6 credits for 8K, and 12 credits for 16K. Cost is fixed per output size, with no per-megapixel or processing-time billing.
Can I upscale AI-generated images?
Yes. The upscaler works on any image type, including AI-generated images from any model. You can generate an image on Keyo Studio and upscale it to production quality in the same platform, without switching tools.
