Every "free" file tool asks the same thing of you: your document. Not your consent — your document. What comes back is a smaller file, and the price is paid in ways nobody states on the download page.
When you press convert on a typical free online tool, three things happen in order: your file is sent to a server, the server does the work, and a link appears for a few hours. The middle part is invisible and the first part is the tell. The business model is the server's cost — and the server's cost is covered by either your attention (ads wrapped around the result), your impatience (a paywall after the third use), or your document (files retained, scanned, mined or leaked). You cannot tell which from the outside. That is the deal.
| Typical "free" online tool | Drazil | |
|---|---|---|
| Your file | Uploaded to a server | Never leaves the tab |
| Account | Often required for the good features | Never required |
| Cost | Free tier, then a paywall; or ads | Free, always; about $1 a month to run the site itself |
| Limits | Pages, size, uses per hour | Your device's memory — that is the whole limit |
| Offline | No | Yes, for everything already opened or cached |
| Your data afterwards | Their server has it; maybe forever | Your IndexedDB has it; export JSON and delete any time |
| Source | Closed | The build is public in the way this site is public: readable, dated, honest |
It buys the right to convert the document you do not want to show anyone — the medical letter, the contract clause, the assignment before it's due. It buys an offline train ride. It buys a guarantee that your files are not training data, not analytics, not a headline next week. And it buys the only metric that can't be gamed: nothing came in, nothing went out, and the work is finished anyway.
That is the one axis that matters. Everything else is taste. See the tools — or start with Text to PDF and watch your words become a typeset file without a packet ever leaving your machine.
