Example generated with this workflow: Simply upload a image and a watermark file, and the workflow will automatically combine them into a professional watermarked image. Use cases include adding logos to content, branding product photos, or protecting images with copyright marks. Good to know Completely free solution with no ongoing costs or subscriptions Processing typically takes 5-15 seconds depending on image size The workflow uses a polling mechanism to check job completion every 3 seconds Supports standard image formats (PNG, JPG, etc.) No credit card required to get started How it works The Form Trigger creates a user-friendly upload interface for two files: main image and watermark Both images are uploaded simultaneously to the API's file storage via parallel HTTP requests The uploaded file URLs are aggregated and used to create an image composition job The workflow polls the API every 3 seconds to check job completion status Once completed, the final watermarked image is downloaded and returned as a file download The watermark is automatically positioned in the bottom-right corner with 50% opacity, but this can be easily customized. How to use The form trigger provides a clean interface, but you can replace this with other triggers like webhooks or manual triggers if needed. The workflow handles all file processing automatically and returns the result as a downloadable file.
