Your files stay on your computer. Do not take our word for it.
Every other site that does this asks you to trust a sentence in a privacy policy. This one can be checked in about a minute, by you, right now. Here is how.
counting…
Three ways to check, hardest first
- Pull the plug. Open the tools, use one once so your browser has the files, then turn off your Wi-Fi or switch on aeroplane mode and reload the page. It still opens, and every tool still works. Software that sends your files somewhere cannot do that.
- Watch the network yourself. Press F12 (⌥⌘I on a Mac), open the Network tab, then merge, convert or compress something. You may see tiny requests to /api/events saying only that a tool started, finished or failed. You will never see the document upload — the request stays tiny whatever the file size.
- Read what is running. Right-click anywhere and choose View page source. There is no advertising tracker and no third-party analytics script. This very page loads nothing at all — no font, no stylesheet, no script from outside — which is why the number above can be zero.
What we do and do not do
| Send your files to a server | Never. There is no server to send them to. |
| Ask for an account, an email, or a payment | No. None of the tools are gated. |
| Set cookies, build advertising profiles, or run advertising | None of the three. |
| Measure whether a tool opened, finished, failed, or saved | Yes — as anonymous operational counts on Cloudflare. No file name, size, type, contents, entered text, settings, output, IP address, full URL, referrer, or persistent visitor ID is written to that dataset. Do Not Track is respected. |
| Limit file size or how many files you may do | No — the limit is your own computer's memory. |
| Keep anything after you close the tab | Nothing. Your files were only ever in this tab's memory. |
| Store one small thing on your device | Yes — which of the two colour themes you picked, so the page does not forget it. It lives in your browser and never leaves it. |
| Keep a copy of the site so it works offline | Yes — your browser caches the code, the same way it caches any page. You can clear it any time from your browser's settings. |
Why this is possible at all
Browsers grew up. Reading a PDF, decoding a photograph, recognising letters in a scan, drawing a CAD file — all of that now runs perfectly well inside a tab, on your own processor. The usual reason a file-conversion site uploads your document is not that it must; it is that a server is easier to bill for and easier to measure. We chose the harder build and kept the files where they started.
One honest caveat: the recognition models and the drawing decoder are large, so the first time you use those particular tools your browser downloads that code from this site — code coming down, never your files going up. After that they work offline too.
