Start from categories when you are exploring, or jump to All Tools when you already know the name of the utility you need. The search box updates the URL so you can bookmark a filtered view for recurring tasks such as PDF merges or JSON formatting.
Each individual tool page on ToolzBanana includes a detailed article beneath the interactive workspace. That content is written for humans first and explains privacy boundaries, common pitfalls, and suggested workflows—so you are never looking at a bare widget without context.
Prefer a narrower starting point? Open the code and data workspace, jump to image editing and conversion tools, or go straight to PDF merge, split, and export workflows.
