This ComfyUI tutorial workflow shows you how to cleanly upscale a single image using Bria’s dedicated resolution enhancement API. The core BriaIncreaseResolution node takes an input from LoadImage, sends it to the Bria API, and returns a higher-resolution version that preserves the original content without inventing new details or regenerating the scene. It supports JPEG and PNG inputs in RGB, RGBA, or CMYK color modes, and enforces a maximum area of 8192×8192 pixels to keep processing fast and reliable. Built-in content moderation checks both the input and the enhanced output for policy compliance before finalizing results.
Technically, the graph is straightforward and focused: LoadImage feeds your source into BriaIncreaseResolution, where you specify your target dimensions or scale within the allowed limits. ImageCompare then places the original and the upscaled image side-by-side so you can evaluate edge fidelity, text clarity, and fine textures at a glance. Finally, SaveImageAdvanced writes the enhanced output with your preferred filename, folder, and format (PNG for lossless graphics and text, JPEG for smaller photo files), making it a practical tool for print prep, large digital displays, and professional design workflows that need reliable resolution increases without stylistic changes.

Usa este flujo de trabajo desde código
Cada flujo de trabajo de Comfy es un grafo JSON. El siguiente payload es este flujo de trabajo, exactamente como lo ejecuta ComfyUI: descárgalo desde la URL, guárdalo en control de versiones o cárgalo en ComfyUI y ejecútalo nodo por nodo.
Ejecuta desde TypeScript o Python con el Comfy SDK. El mismo código funciona en Comfy Cloud o en un ComfyUI propio: solo cambia la URL base.
// Install (beta)
npm i @comfyorg/sdk
// Run this workflow (TypeScript)
import { Comfy } from "@comfyorg/sdk";
const client = new Comfy({ apiKey: "comfyui-..." });
const wf = await client.workflows.fromFile("workflow_api.json");
const job = await client.run(wf);
await job.getOutputs("<output-node-id>")[0].toFile("output.png");El SDK utiliza un flujo de trabajo en formato API: abre este flujo de trabajo en ComfyUI y usa Archivo → Exportar flujo de trabajo (API).
El acceso a la API de Comfy Cloud requiere un plan con clave API.
