QUICK ANSWERStart with the tool that matches your immediate input.
Open HTML Language Attribute Checker first when its stated purpose matches the result you need now. Use Image Alt Attribute Checker only when it solves a separate next task.
This guide is for designers, developers, editors, and site owners. Start with HTML Language Attribute Checker when your immediate task is to check common html language attribute issues and receive practical improvement guidance. Move to Image Alt Attribute Checker only when you also need to check common image alt attribute issues and receive practical improvement guidance.
The goal is not to run two tools automatically. It is to finish the first narrow task, inspect its result, and then decide whether Image Alt Attribute Checker solves a genuinely different next step.
Both tools sit in Accessibility Tools, but they handle different inputs or outcomes. Keeping those roles separate reduces repeated work and makes verification easier.
