Your file never leaves your device
Private file tools that run in your browser
Most online converters ask you to upload the file first. These do not, because there is nothing to upload it to: the whole site is static, and every tool runs as JavaScript inside this tab. Turn off your Wi-Fi and they still work.

Adaptive thresholding cleans up uneven scans and shrinks scanned files.
Why this is different
Nothing is uploaded
There is no server to receive your file. The site is a set of static files, with no upload endpoint, no database and no accounts.
The browser enforces it
A Content-Security-Policy restricts this page to talking to its own origin, so even a bug could not send your file elsewhere. Your browser applies that, not us.
It works offline
Once a page has loaded, it keeps working with the network switched off. That is the simplest proof that your file is not going anywhere.
Check it for yourself
- 1. Open any tool below and let the page finish loading.
- 2. Turn off Wi-Fi, or switch on airplane mode.
- 3. Drop a file in. It converts normally, because nothing is being sent.
