Frequently asked questions
Are these tools really free?
Yes. Every tool here, the Markdown converters and the invoice generator, is free with no account, no watermark and no usage cap. They are built by the GPT Workspace team as a companion to the Chrome extension.
Do my files get uploaded?
No. PDF, Word and Markdown conversion and the invoice preview and PDF run in your browser. The only network requests are the optional Open in Google Docs button, which sends the Markdown you chose to convert, and the invoice generator's optional AI mode, which sends the sentence you typed.
Which Markdown flavour is supported?
GitHub-flavoured Markdown: tables, task lists, fenced code with language hints, strikethrough, footnotes and autolinks, plus Mermaid diagrams and LaTeX math in the viewer and PDF export.
Do the tools work on a phone?
Yes. Every page works in mobile Safari and Chrome, with the editor and preview as tabs. File drops become a file picker.
