QUICK ANSWERStart with the tool that matches your immediate input.
Open Image Resizer first when its stated purpose matches the result you need now. Use WebP Image Converter only when it solves a separate next task.
This guide is for creators, marketers, designers, and website owners. Start with Image Resizer when your immediate task is to open the original Image Resizer and complete the task with a focused browser-based interface. Move to WebP Image Converter only when you also need to open the original WebP Image Converter and complete the task with a focused browser-based interface.
The goal is not to run two tools automatically. It is to finish the first narrow task, inspect its result, and then decide whether WebP 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.
