Portrait Upscaler
Generated on PixelDojo with Portrait Upscaler. Produced by PixelDojo's generation pipeline.
Portrait Upscaler is priced by the size of its output, read from your image before the charge. Our face focused 4x upscale of a 1024 by 1392 portrait returned a 4096 by 5568 file, 22.8 megapixels, in about 107 seconds on August 26, 2026. That is 12 credits at today's price; it was charged 2 that day, when the price came from the scale factor alone. It runs Crystal Upscaler, tuned specifically to hold facial detail through a large upscale rather than treating a face like any other texture. Here is what the extra resolution actually revealed.

How Portrait Upscaler prices and behaves
Cost follows the output size, in bands
The output (width x height x scale_factor squared) is billed in bands: 1.5 credits up to 4.4 megapixels, 3 up to 8.8, 6 up to 17.6, 12 up to 27.5, 24 up to 55, 48 up to 110 and 96 above that. A 1 megapixel portrait at the default 4x is 6 credits; our 1.4 megapixel one is 12.
What 4x actually revealed
At 4096 by 5568, individual skin pores and fine wrinkle lines on the hands became visible in a way the 2x upscalers in the catalog did not show. The net's woven fiber also separated into clearer individual strands rather than a soft mesh.
It is one setting, one input
The entire request is an image URL plus a scale_factor from 1 to 8. There is no prompt, no creativity dial, no style setting. This is a narrow, single purpose face and portrait upscaler, not a general creative refinement tool.
The price is measured before you pay it
We read your image's size before charging, so the price you see is the price you pay. The bands follow the provider's own output-size tiers, which is why the price steps rather than rising smoothly per pixel.

Why Choose Pixel Dojo for Portrait Upscaler
Professional-quality results with cutting-edge AI technology
Priced by output size, 12 credits for our 4x test
1.5 credits up to 4.4 megapixels of output, 3 up to 8.8, 6 up to 17.6, 12 up to 27.5, 24 up to 55, 48 up to 110 and 96 above that. Our 22.8 megapixel 4x result is 12 credits today; it was charged 2 on August 26, 2026.
About 107 seconds, measured
Timed on August 26, 2026 from request to a finished 4096 by 5568 file at 4x.
Face and skin detail is the point
Pore level texture and fine wrinkles came through clearly, which is what a face specific upscaler is supposed to do that a general one does not prioritize.
How It Works
How our 4x upscale was made:
Start from a clear portrait
We used a close crop already at 1024 by 1392. The narrower the face fills the frame, the less this specific tool has to work with.
Leave scale_factor at its default of 4
On our 1024 by 1392 source that is a 22.8 megapixel output, the 12 credit band today. A lower scale drops into a cheaper band, and pushing toward 8 climbs into the 48 and 96 credit bands.
Run it in the app or over the API
From the tool page, or POST to /api/v1/models/face-enhance/run. Ours returned in about 107 seconds; charged 2 credits on August 26, 2026, it is 12 at today's price.

Common Questions
Everything you need to know about Portrait Upscaler
How much does Portrait Upscaler cost?
It is priced by output size, read from your image before the charge: 1.5 credits up to 4.4 megapixels of output, 3 up to 8.8, 6 up to 17.6, 12 up to 27.5, 24 up to 55, 48 up to 110 and 96 above. A 1 megapixel portrait at the default 4x is a 16 megapixel output, 6 credits. Our 1024 by 1392 test portrait at 4x is 12 credits today; it was charged 2 on August 26, 2026.
How fast is Portrait Upscaler?
About 107 seconds in our August 26, 2026 run at the default 4x scale, from request to a finished 4096 by 5568 file.
How is it different from Creative Upscaler and Clarity Pro?
Creative Upscaler is a flat 2.5 credits and general purpose. Clarity Pro charges 1 credit per output megapixel and targets photorealistic identity preservation across any subject. Portrait Upscaler is narrower still: it is tuned specifically for faces, with no prompt or creativity setting, just an image and a scale factor.
What scale factors does it accept?
Any value from 1 to 8. The default is 4. Higher values cost more, in the seven output size bands above.
Does it work on photos that aren't close up portraits?
It is built and tuned for face detail specifically, so a subject where the face is small in the frame will see less benefit than a close portrait like the one in our test.
How do I call it from the API?
POST to /api/v1/models/face-enhance/run with your API key, an image URL, and optionally scale_factor. Same key as every other model in the catalog.
