Upscale images with Topaz Creative. Add plausible new fine detail up to 4x resolution with Bloom 2/Bloom/Bloom Realism. Try free — pay per generation.
Upscale an image with Topaz's creative/generative-detail model, adding plausible new fine detail while enlarging up to 4x.
About this model
Topaz Upscale Image Creative enlarges an image up to 4x while inventing new, plausible fine detail — hair strands, fabric weave, skin texture — rather than just smoothing pixels. It runs on Topaz's Bloom 2, Bloom, and Bloom Realism models, with optional autoprompting and adjustable creativity so you can dial in how much new detail the model is allowed to imagine versus how closely it should stay to the source. Works well on soft phone photos, old scans, and AI-generated images that need a sharper, more detailed finish. See also Topaz Upscale Image Generative for a more faithful reconstruction-focused alternative, or Topaz Upscale Image Precision when you need to preserve the original look exactly.

Provide an image: Set image_url to any publicly accessible image URL.
Pick a model: Choose Bloom 2 (default, latest), Bloom, or Bloom Realism depending on how photoreal you want the added detail.
Tune creativity: Set creativity (1-9) to control how much new detail the model invents, and color_preservation to keep the original palette.
Set the scale: upscale_factor accepts 1-4x. Choose output_format (jpeg or png).
Submit and poll: POST to /api/v1/topaz-upscale-image-creative, then poll /api/v1/predictions/{request_id} (or use webhook_url) until status is completed.

Frequently asked
It enlarges an image up to 4x while generating new, plausible fine detail using Topaz's Bloom family of creative upscale models.
Creative leans furthest toward inventing new detail for a more stylized, sharpened result. Generative reconstructs realistic detail (faces, textures) more conservatively, and Precision stays closest to the original pixels.
Any standard JPEG/PNG/WebP URL works as input. Output can be requested as `jpeg` or `png` via `output_format`.
Cost is based on the actual output megapixels after `upscale_factor` is applied, billed per started 2-megapixel block.
Yes — the `creativity` parameter (1-9) controls how much new detail the model invents, and `color_preservation` keeps the original color palette intact.
Yes, pass `webhook_url` in the request body or as a `?webhook=` query parameter and muapi will POST the final result when processing completes.
