    🧩 Load Image from HTTP URL – Custom Node for ComfyUI

    By @jerrywap GitHub stars

    ComfyUI Node

    🔍 Description

    Load Image from HTTP URL is a lightweight but powerful custom node for ComfyUI that allows you to fetch images directly from a remote URL and use them in your workflows without manual uploads or preprocessing.

    Instead of uploading an image file manually, you can pass a publicly accessible image URL — and the node will handle downloading, decoding, and converting it into an image tensor compatible with ComfyUI.

    This is especially useful when you're:

    • ⚙️ Building ComfyUI as an API service
    • 📡 Receiving image URLs from client apps, webhooks, or JSON payloads
    • 🌐 Working with dynamic content from external APIs or cloud storage

    By skipping the file transfer step, you reduce friction, improve performance, and make your workflows more automation-friendly.

    ✨ Features

    • 📡 Downloads an image from an HTTP/HTTPS URL
    • 📷 Converts it to a proper image tensor (IMAGE) for ComfyUI
    • 🧼 Includes graceful fallback (returns a blank black image on error)
    • ✅ Supports JPEG, PNG, WebP, etc. (any format supported by Pillow)
