Interactive Image Editor with FLUX.1 Inpainting Tool

This n8n workflow powers a fully interactive, web-based image editor that replicates Photoshop's Generative Fill feature using the FLUX.1 API for inpainting. Users access a dynamic HTML interface via a webhook, featuring an adjustable brush tool for precise area selection, text prompt input, and controls for FLUX model parameters. It supports uploading custom images or using mock examples, enabling seamless iteration on edits with side-by-side original vs. generated image comparisons powered by Konva.js and img-comparison-slider.

The workflow handles the full image processing pipeline: capturing mask and prompt data from the browser, sending requests to the FLUX Fill API (via HTTP Header Auth), and returning high-quality inpainted results. No desktop software needed—everything runs in the browser, making it ideal for quick creative tasks.

Benefits include massive time savings for non-designers, perfect for product catalog updates (e.g., seasonal changes), marketing visuals, e-commerce imagery, and social media content. It's scalable for teams, requires only FLUX API credentials, and offers reusable outputs for further automation.
