Why the labs exist

Most online file tools ask you to upload your documents to a stranger’s server. These do the opposite.

Private by design

Everything runs in your browser using JavaScript. Your PDFs, photos, passwords and previews stay in your device’s memory and vanish when you close the tab. We could not read them even if we wanted to.

Fast and simple

There is no queue and no waiting for an upload to finish. Files are processed locally, so even large documents and photos open in seconds on a modern phone or laptop.

Free, supported by you

No account, no watermark, no paywall. The labs are kept free by unobtrusive advertising and optional coffee donations from people who find them useful.

Works everywhere

The labs adapt to phones, tablets and desktops, and use open web technology, so there is nothing to install and nothing to update.

How it works

  1. Pick a lab

    Choose the tool that matches your file: PDF Lab for documents, Photo Lab for pictures.

  2. Open your file

    Drop it on the page or tap to select it. It is read by your browser, not uploaded anywhere.

  3. Edit and save

    Make your changes, then download the result. Close the tab and every trace of the file is gone.

Questions

Are my files uploaded anywhere?

No. The labs run entirely in your browser. Your files are never sent to our servers or to any third party, which is why we cannot recover a lost password or restore a closed session.

Do I need an account?

No. There is no sign-up, no login and no email required. Open a lab and start working.

Is it really free?

Yes. The labs are free to use with no watermark. They are supported by advertising and by voluntary donations through Buy Me a Coffee.

What do the live previews on this page show?

They are the actual lab websites loaded in a small window, so you can see the current interface before opening it. They are display-only and load only when you scroll to them.

Will there be more labs?

Yes. Four more tools are planned and will appear in the empty slots above as soon as they are ready.

How do I report a problem or suggest a tool?

Write to contact@clickfreetools.com. Please describe what you were doing and which browser you use, and do not attach your files.
