When you open one of our tools, your browser downloads a small program and the open-source libraries it needs. After that, everything happens inside the browser tab on your own device. The file you choose is read by that program, changed, and handed back to you as a download. It is not sent over the internet.
What this means for you
- Privacy. We never see your documents, so we cannot store them, read them or lose them.
- Speed. There is no upload or download of your file to a server, so small and medium files finish in seconds.
- Offline use. Once a tool page has loaded, it keeps working if you go offline.
What we save
Nothing, unless you ask us to. Without an account we do not keep your files, your results or a list of what you did. If you later choose to create an account and save a document, we keep that document until you delete it, and not before. You can delete it at any time.
If a tool needs our server
Some jobs, such as turning a Word document into a PDF, cannot be done inside a browser. If we add a tool like that, we will mark it clearly, tell you before you choose a file, delete the file soon after it is processed, and say so in the privacy policy. Tools that need an account will say so in the same way. The tools listed here today all run in your browser.
The limits
- Very large files need a lot of memory on your device. A phone may struggle with files of several hundred pages with big pictures.
- A PDF that needs a password to open cannot be read by these tools. Remove the password first.
- Compression works on the pages and pictures in the file. A file that is already well compressed may not get smaller.
What we use
The tools are built with the open-source libraries pdf-lib and pdf.js for working with PDF files, and JSZip for making ZIP files. They are served from this site, so nothing is loaded from other companies.
