By the numbers

Big enough to be useful. Small enough to trust.

One codebase, no backend for tool processing, and a hard rule that nothing you paste or open is transmitted anywhere.

Why it is private

There is no upload step to worry about.

Most "online" tools are a form that posts your file to someone else's machine. TextWonder skips that middle box entirely — the browser already has a PDF engine, an image decoder and a JSON parser, so we use those.

✓
Nothing to breach

We never hold your file, so there is no bucket for anyone to find later.

✓
Nothing to wait for

No round trip means results appear as fast as your laptop can compute them.

✓
Nothing to sign up for

No account exists because there is no server-side state to attach one to.

Questions

The six we get asked most.

Is anything actually uploaded?+
No. Every tool is JavaScript running in your own tab. Your text, PDFs and images are read by the browser, processed in memory and written back out — nothing is sent to a server, so there is nothing for us to store, log or leak.
Do I need an account?+
There is no account, no email wall and no trial. Open a tool, use it, close the tab. Nothing is saved unless a tool explicitly offers to remember a setting in your own browser storage.
Is it free forever, or free for now?+
Free. All 234 tools, all suites, no premium tier and no per-file limits. The site is supported by advertising, not by charging for the tools.
Does it work on a phone?+
Yes — every tool is responsive and the file-based ones use the standard mobile file picker, so PDFs and images from your camera roll work the same way they do on desktop.
Will it work offline?+
Most tools keep working once the page has loaded, because the processing is already on your device. The exceptions are the handful that call an external service, such as certain text-to-speech voices.
How big a file can I give it?+
The limit is your device, not our plan. Browser memory is the only ceiling, which in practice means a few hundred megabytes on a modern laptop and rather less on an old phone.

No account. No upload. No cost.
