Real Detail Recovery, Not Just Resizing

Enhancer는 픽셀을 늘리는 대신 실제 디테일을 재구성합니다. 데모 페어는 287×367 스캔을 1144×1464로 복원하고 콘셉트 아트를 4배 확대합니다.

Try It on Your Own Image

Three Output Tiers

HD (1K) enhancement is free with a Hyper3D account. When you need bigger output, the 2K and 4K tiers unlock with a subscription.

원본 품질이 작업을 가로막는 곳 어디서든 향상된 이미지를 사용하세요.

Image to 3D

Sharpen reference photos before Rodin image-to-3D. Cleaner edges, materials, and silhouettes give the generator a stronger signal to work from.

Product Visuals

E-commerce

Product Visuals

Turn small, compressed product shots into crisp 2K–4K images for listings, mockups, and 3D product visualization work.

Game Art

Game Development

Game Art

Upscale concept art and old low-resolution renders into sharp references for modeling, texturing, and pitch decks.

Photo Restoration

Realistic Style

Photo Restoration

Recover old photos and scanned artwork. A high Similarity setting keeps the result faithful while clarity and detail improve.

자주 묻는 질문

Enhancer가 실제로 동작하는 방식에 근거한 답변: 형식, 제한, 컨트롤, 가격.

What does the AI Image Enhancer actually do?

It upscales and enhances an uploaded image to HD (1K), 2K, or 4K resolution, recovering detail, color, and clarity with a generative AI model. You control how aggressive the enhancement is, compare before and after on a slider, and download the result as a PNG.

Which file types and sizes can I upload?

JPEG, PNG, and WebP images are accepted, by click-to-browse or drag and drop. Files must be under 3 MB after automatic compression, and the shortest side of the image must be at least 128 pixels.

Is the Image Enhancer free to use?

Yes — the tool is labeled 'Free to all' in OmniCraft. You need a free Hyper3D account to upload, HD (1K) enhancement is free, and the 2K and 4K output tiers unlock with a subscription.

What do AI Strength and Similarity control?

AI Strength (0–100%, default 25%) sets how much new detail the model may generate — its creativity. Similarity (0–2, default 1.0) controls resemblance to the source: higher values stay closer to the original. Dynamic (0–10, default 6) and Sharpness (0–10, default 0) fine-tune contrast range and edge crispness.

Can I get repeatable, deterministic results?

Yes. Enter a positive number in the Seed field and the same image with the same settings will produce the same result. Leave the seed at its default (-1) for a fresh variation on every run.

Do I need to write a prompt?

No. The prompt box is optional — a short description of what's in the image (up to 255 characters) can guide the model, but the Enhancer works without any text input.

How do I check the result before downloading?

The result opens in a before/after viewer with a draggable divider. You can zoom from 0.2x to 2.5x with the mouse wheel and pan by dragging, so you can inspect edges, textures, and fine detail at pixel level.

What format is the downloaded result?

Enhanced images download as PNG files with a timestamped filename, ready to drop into image-to-3D, texture, or design workflows without further conversion.
