QUICK ANSWERStart with the tool that matches your immediate input.
Open Batch Image Converter first when its stated purpose matches the result you need now. Use Threshold Image Converter only when it solves a separate next task.
This guide is for creators, marketers, designers, and website owners. Start with Batch Image Converter when your immediate task is to convert your file or data with the Batch Image Converter directly in your browser. Move to Threshold Image Converter only when you also need to convert your file or data with the Threshold Image Converter directly in your browser.
The goal is not to run two tools automatically. It is to finish the first narrow task, inspect its result, and then decide whether Threshold Image Converter solves a genuinely different next step.
Both tools sit in Image & Design, but they handle different inputs or outcomes. Keeping those roles separate reduces repeated work and makes verification easier.
