How to choose the right tool
Choose file tools by the file type first, then check the page privacy note so you know whether the workflow runs locally or needs a supported browser feature.
Quality and privacy notes
Use the examples and FAQs on each tool page before relying on an output. Browser-local tools should keep input on the page, while file and web checks may depend on the browser capability described on the individual page.
