Tencent Image Upscaler (MPS advanced super-resolution)
Tencent Image Upscaler is developed by Tencent. Atlas Cloud (operated by Atlas Cloud AI LLC) provides access to it and does not own it. All trademarks belong to their respective owners.
Tencent Image Upscaler
Tencent Image Upscaler enhances an existing image to a higher resolution and better quality using Tencent Cloud MPS (Media Processing Service) advanced super-resolution. Provide a public image URL, pick a super-resolution type and scaling mode, and receive an enhanced image URL.
Highlights
- Image-to-image enhancement: Upscale and enhance an existing image without changing its content. User-uploaded images and third-party-model outputs are both supported.
- Four SR engines:
standard(generic, fastest),super(AIGC scenes),ultra(more detail enhancement, default), andfidelity(ultra high fidelity for e-commerce). - Flexible scaling: Scale by a factor (
percent), fit given dimensions keeping aspect ratio (aspect), or force exact dimensions (fixed). - Hosted output: Enhanced images are transferred to AtlasCloud storage and returned as long-lived URLs (the upstream Tencent COS URL is never exposed).
Parameters
| Parameter | Required | Description |
|---|---|---|
model | Yes | Use tencent/image/upscaler. |
image_url | Yes | Input image URL. Must be a publicly accessible HTTP(S) URL — Tencent MPS fetches it before processing, so signed URLs should be long-lived. Supported formats: .jpg / .jpeg / .png. |
type | No | Super-resolution engine: standard (fastest ~5s), super (AIGC scenes ~15s), ultra (more detail, default ~15s), fidelity (ultra high fidelity ~30s). |
mode | No | Scaling mode: percent (default, scale by a factor), aspect (keep aspect ratio, scale to fit given dimensions), fixed (force exact dimensions). |
percent | No | Scale factor for mode=percent. 1.0 = keep resolution (enhance only), 2.0 = 2x. Range 1.0–10.0. Default 2.0. |
width | No | Target width in pixels (for mode=aspect / fixed). |
height | No | Target height in pixels (for mode=aspect / fixed). |
long_side | No | Target long-edge in pixels (for mode=aspect / fixed). Alternative to width/height. |
short_side | No | Target short-edge in pixels (for mode=aspect / fixed). Alternative to width/height. |
encode_format | No | Output image format: JPEG (default), PNG, WEBP, BMP. |
encode_quality | No | Output encode quality 1–100 (applies to lossy formats). Default 80. |

Example Request
{ "model": "tencent/image/upscaler", "image_url": "https://static.atlascloud.ai/media/images/8137931a-0d1b-43d2-a70f-b041ad7d775f.jpg", "type": "ultra", "mode": "percent", "percent": 2.0 }
Processing
Enhancement is asynchronous. Submit a request to receive a task id, then poll the result endpoint until status is completed (or failed). Enhanced output is transferred to AtlasCloud storage and returned in outputs as a long-lived URL.
