    How PDFToolkitX works

    Your files stay on your device

    Most online converters send your document to a remote server. Our tools load a small program into your browser and do the work there. You can even disconnect from the internet after the page has loaded and the tools keep working.

    Built on proven open-source libraries

    PDF reading and rendering use PDF.js, the library developed by Mozilla for Firefox's PDF viewer. Creating and editing PDF files uses pdf-lib. Both are widely used and openly developed.

    Simple by design

    Each tool does one job with a few clear options. Pick your files, choose a setting if you need to, and download the result. No accounts, no email address, no waiting in a queue.

    Frequently asked questions

    Are these PDF tools really free?

    Yes. Every tool on the site is free to use, with no account, no watermark and no daily limit. The site is supported by advertising.

    Are my files uploaded?

    No. The tools run inside your web browser using JavaScript, so your files are read and processed on your own device. They are not sent to our server or anyone else's.

    Do the tools work on a phone?

    Yes. They work in current versions of Chrome, Safari, Edge and Firefox on phones, tablets and computers. Very large files are faster on a computer.

    Is there a file size limit?

    We do not set one. Because processing happens on your device, the practical limit depends on its memory. Ordinary documents are handled in seconds.

    Can I edit the text inside a PDF?

    Not with these tools. They organize and convert PDFs (merge, split, rotate, convert to and from images and text). Editing text requires a PDF editor or the original document.
