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.
API
Use this workflow from code
Every Comfy workflow is a JSON graph. The payload below is this workflow, exactly as ComfyUI runs it — fetch it from the URL, keep it in version control, or load it in ComfyUI and run it node by node.
Run it from TypeScript or Python with the Comfy SDK. The same code targets Comfy Cloud or a ComfyUI you host yourself — only the base URL changes.
// 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");The SDK takes a workflow in API format: open this workflow in ComfyUI and use File → Export Workflow (API).
Comfy Cloud API access requires a plan with an API key.
