Convert images without uploading them

file4edit does not upload the images you open — every conversion, resize and PDF operation runs in your own browser, on your own processor. Once the browser has downloaded the HTML, CSS and JavaScript there is no further request for it to make and nowhere to send a file to. There are no accounts, no cookies, no third-party scripts and no error reporting. One anonymous row per page view is counted at the edge — date, path, country and referring host, kept for ninety days, with nothing in it that identifies a visitor — and your own settings stay in your browser's local storage.

How it works

  1. Open the network panel In your browser's developer tools, switch to the network panel and leave it open.
  2. Convert a file Drop an image into any tool and process it. No request appears in the panel, because the file is read from disk into the tab's memory and never leaves it.
  3. Disconnect from the internet Turn your connection off and keep working. The service worker caches only file4edit's own files and never intercepts a request it did not serve, so the tools carry on with no network at all.
  4. Clear what is stored, if you want to The settings page has a button that removes your default format, quality, filename pattern, theme and pinned tools from this browser's local storage.

Questions

Does file4edit upload my images to a server?
No. file4edit is a static website with no server component. Your browser downloads the page once, and every conversion after that is JavaScript running on your own machine — the image is read from disk into the tab's memory and is never sent anywhere. When you close the tab, the memory holding it is released.
How can I verify that nothing is uploaded?
Open your browser's developer tools, switch to the network panel, and convert a file: no request appears. A stronger test is to disconnect from the internet entirely and keep working — file4edit installs a service worker on first load, so it keeps functioning with no connection, which a service that uploaded your file could not do.
Does file4edit store anything on my device?
Only preferences, and only in your own browser. Your default output format, quality, filename pattern, theme and pinned tools are kept in local storage on your machine under the keys file4edit.prefs and file4edit.pins. There are no cookies, no analytics and no error reporting. Clearing your browser data, or the clear button on the settings page, removes them.
