QUICK ANSWERStart with the tool that matches your immediate input.
Open Rounded Corners Image first when its stated purpose matches the result you need now. Use Sharpen Image only when it solves a separate next task.
This guide is for creators, marketers, designers, and website owners. Start with Rounded Corners Image when your immediate task is to use the Rounded Corners Image to complete this file task privately in your browser. Move to Sharpen Image only when you also need to use the Sharpen Image to complete this file task privately 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 Sharpen Image 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.
