Features
🌆 Ultimate Image Upscaler
Ultimate Image Upscaler is a next-generation AI-powered upscaler and enhancer that reconstructs stunning detail, texture, and clarity — turning any low-resolution photo into a high-definition masterpiece.
With our creativity control, you can decide how far the model should “reimagine” the image: from subtle restoration to bold, high-fidelity enhancement. Whether for portraits, landscapes, or digital art, every pixel shines with cinematic precision.
If you’re looking for a more affordable option, check out the Standard Image Upscaler.
✨ Why it looks incredible
- AI detail reconstruction: restores missing features like hair strands, fabric texture, and fine lighting gradients.
- Smart edge recovery: sharpens outlines and removes blur while preserving realism.
- Dynamic creativity scaling: adjust the “creativity” slider to balance accuracy vs. artistic reimagination.
- Noise & artifact cleanup: removes compression noise, color banding, and digital grain.
- Cinematic color grading: enhances tonal contrast and depth for a naturally vivid finish.
⚙️ Limits and Performance
- Input formats: JPEG, PNG, WEBP
- Output formats: JPEG, PNG, WEBP
💰 Pricing
Upscale only for $0.05!!!
🚀 How to Use
- 📤 Upload your image (JPG/PNG/WEBP).
- 🎛️ Choose your upscale ratio (2×, 4×, or 8×).
- 🎨 Adjust creativity for detail vs. realism.
- ▶️ Click Run to generate the enhanced image.
💡 Pro Tips
- For photo restoration, keep creativity low (0.5–1.0) to preserve realism.
- For artistic reimagination, try creativity 2.0+ — it can recreate missing details in new styles.
- Use higher-resolution outputs for prints, posters, or cinematic use.

Request Parameters
| Parameter | Type | Required | Default | Range | Description |
|---|---|---|---|---|---|
| image | string | Yes | - | The URL of the image to generate an image from. | |
| creativity | number | No | - | -2 ~ 2 | Controls how strongly the upscaler will try to improve the image quality. |
| target_resolution | string | No | 4k | 2k, 4k, 8k | The target resolution of the generated media. |
| output_format | string | No | jpeg | jpeg, png, webp | The format of the output image. |
| enable_base64_output | boolean | No | false | - | If enabled, the output will be encoded into a BASE64 string instead of a URL. This property is only available through the API. |
| enable_sync_mode | boolean | No | false | - | If set to true, the function will wait for the image to be generated and uploaded before returning the response. It allows you to get the image directly in the response. This property is only available through the API. |
