Where it started

To compress a PDF, convert an image or open a file you can’t read, most free sites ask you to upload your file to their server. The processing happens on their side, and then you get the result back.

That seems harmless for a holiday photo. It is much less so for a pay slip, a bank statement, a contract, an ID card or a medical record, which are precisely the documents people want to compress, merge or redact.

Once the file has gone, you have no way of knowing how long it is kept, who can access it, where it is stored, or what happens to it if the company shuts down or changes hands.

What this site does instead

All the processing happens in your browser. The file you drop is read, transformed and handed back by your own device. It goes nowhere, because there is nowhere for it to go: the site has no server that receives files.

This isn’t a promise you have to take on trust. You can check it yourself in three clicks: open your browser’s developer tools (F12), go to the “Network” tab, then drop a file. You will see that no request goes out during processing. The only requests you can see are those of the ad network, when the page loads, and they carry nothing from your file.

You can go further still: cut your internet connection once the page has loaded. The tools keep working.

What the site doesn’t do

No account, no email address, no password. No limit on size, number or frequency. No watermark forced onto your documents. No “premium” version.

The site keeps at most three pieces of information in your browser: the light or dark theme, the chosen language, and the tools you opened most recently so it can offer them faster. None of this leaves your device and none of it identifies you. Your choice about ads, for its part, is recorded by the consent window of Google, the ad network, so that it can respect it. You can change it at any time from the manage my consent page.

The tools that don’t exist here, and why

Three common tools were left out on purpose.

Password-protecting a PDF. PDF encryption can be cracked offline in a few minutes with free tools.

Converting a video. Doing it in the browser would mean making you download a heavy engine file.

Converting a PDF to Word. Converters that give a faithful result need a server.

Every published tool also states, on its own page, what it can’t do: a conversion that loses quality, a layout that doesn’t come through, a texture that isn’t carried over. These limits are written down before you use the tool, not discovered afterwards.

Who publishes this site

WizeFile is published in France. The publisher’s identification details are in the legal notice.

It is an independent project. It belongs to no group, is funded by no investor and sells no data, for the simple reason that it collects none.

The full identity of the publisher and of the host are in the legal notice.

How the site is funded

The service is free and will stay free. It is meant to be funded by advertising, shown in spaces clearly marked as such.

An ad network stores its own trackers, and it is the only part of the site that relies on a third party. Your consent is asked for beforehand, and you can withdraw it at any time from the manage my consent page. The details are in the privacy policy.

This changes nothing about how your files are processed: they stay entirely on your device in every case, whether you accept the trackers or not.

How it is built

The site is written in HTML, CSS and JavaScript, with no application framework. Every library it uses is hosted on its own domain: no font, no tool and no image on the site is loaded from a third-party server. The one exception is the ad network that funds the site, whose code comes from Google and which is described in the privacy policy. Apart from that, your visit is disclosed to no company you haven’t chosen.

The open-source libraries used and their licenses are listed in the legal notice.

A question, a bug, an idea?

Feedback is useful, especially bug reports: a tool that fails on a specific file can almost always be fixed, as long as we know about it. How to reach us is explained on the contact page.
