Klarfile

Your PDF tools, on your own network.

For many professions, “it all happens in the browser” is not enough: the site itself must come from nowhere. Klarfile can be copied onto your internal server, your file share or a USB stick, and works with no access to the internet at all.

What is delivered: a folder. Nothing else.

Not a virtual machine, not a container, not a database, not a service to administer. The product is a set of static files: HTML, CSS, JavaScript and two libraries. You put it in a folder served by the web server you already have (nginx, Apache, IIS, a network share, a SharePoint folder) and the thirty-seven tools open in the browsers of your workstations.

No outgoing call: no font from a provider, no CDN script, no analytics. The page counter of the public site, the only request that exists here, is removed from the delivered package, not disabled. No licence to validate: nothing checks anything at start-up, because there is nothing to ask. A licence mechanism would be exactly the outgoing call this product forbids itself.

The security headers and the content security policy are delivered with it, ready to apply: that is what makes the promise verifiable on your side too.

Who it is for

A law firm, an HR department, an accounting practice, a hospital, a public authority: for them, sending an exhibit to a service provider is not a preference, it is a prohibition. The task itself stays ordinary: assemble four pages, take one out, black out a name, shrink a 40 MB scan so it fits in an email.

The usual solutions are a processing server to install, maintain and get approved. Here there is nothing to approve: no document ever reaches a server, since the computing happens in the browser of the workstation. The attack surface of a folder of static files is that of your web server, and not one bit more.

Two ways to buy

One-off purchase, 990 € excl. VAT. The package as it stands on the day of delivery, to copy onto as many internal servers as you like, for good. Nothing expires, nothing switches off. You do not receive later versions.

Subscription, 290 € excl. VAT per year. Every new version for a year: the new tools, the fixes, and answers to your questions by email. When the subscription stops, the last version you received stays yours and keeps working.

To order, write to us saying which of the two you want. We reply with a quote, then an invoice payable by bank transfer: that is what a purchasing department expects, and it puts no platform between you and us. Prices are excluding tax; French VAT applies according to your situation.

How it is installed

You receive a ZIP archive and its SHA-256 fingerprint, so you can check it is intact. You unzip it into a folder served by your web server. The package works in a subfolder (`/pdf-tools/`) just as well as at the root of an internal domain: no address is hard-coded. You add the supplied security headers if you want them: they are not needed for it to work, they are needed for it to be *provable*.

There is no step four. No service to start, no scheduled task, no backup to plan, because there is no data.

What this offer does not do

  • It is not a hosted service. We monitor nothing on your side and have no access to your installation. What happens there does not reach us, which also means we cannot see an incident on your behalf.
  • There is no availability guarantee and no on-call support. Subscription support is an exchange by email, on working days, in French or English.
  • Customization is not included (your colours, your logo, an extra tool for your trade): it is possible, and it is quoted separately.
  • No bespoke development is promised by the subscription. It entitles you to the versions we publish, not to the ones we might write for you.
  • The limits of the product are the same as here: no text recognition on a scan, no opening of password-protected PDFs, and everything has to fit in the memory of the tab.

Try it first, it is the same software

The public site is the product: same files, same tools, same code. Open one of them, cut your network connection, work, then look at your browser's “Network” tab. Checking takes thirty seconds, and it is the only thing we ask anyone to grant us: nothing.
