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