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.

Use este workflow a partir do código
Todo workflow Comfy é um grafo JSON. O payload abaixo é este workflow, exatamente como o ComfyUI executa — obtenha-o pela URL, mantenha-o no controle de versão ou carregue-o no ComfyUI e execute nó por nó.
Execute a partir de TypeScript ou Python com o Comfy SDK. O mesmo código serve para o Comfy Cloud ou um ComfyUI hospedado por você — apenas a URL base muda.
// 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");O SDK utiliza um workflow no formato API: abra este workflow no ComfyUI e use Arquivo → Exportar Workflow (API).
O acesso à API do Comfy Cloud requer um plano com chave de API.
