About ArmorPDF

What Is ArmorPDF?

ArmorPDF is a collection of free online PDF tools designed to help you work with PDF files quickly, easily, and privately. Whether you need to merge documents, compress a file for email, split a PDF into separate pages, or perform any number of other common PDF tasks, ArmorPDF has you covered.

Our tools include merging, splitting, compressing, rotating, removing pages, reordering pages, adding page numbers, watermarking, converting PDFs to images, creating PDFs from images, and unlocking password-protected PDFs.

Our Mission: Privacy First

Most online PDF tools require you to upload your files to a remote server. Your documents travel across the internet, get processed on someone else's computer, and are stored, even if only temporarily, on infrastructure you do not control. For sensitive documents, this is a real privacy concern.

ArmorPDF was built on a different principle: your files should never leave your device. Every tool on this site processes your documents entirely within your web browser using JavaScript. There are no file uploads, no server-side processing, and no temporary cloud storage. When you close the browser tab, your data is gone, because it was never anywhere else to begin with.

How It Works

ArmorPDF uses modern web technologies to perform all PDF processing directly in your browser. When you select a file, JavaScript reads it from your device's storage into your browser's memory. The processing, whether it is merging, compressing, rotating, or any other operation, happens using JavaScript libraries running on your computer. The result is generated locally, and when you click “Download,” the file is saved directly from your browser to your device.

No internet connection is required after the page loads. The entire workflow stays on your machine.

No Signup, No Account, Completely Free

ArmorPDF does not require you to create an account. There is no email collection, no login form, and no premium tier. Every tool is fully functional and free to use without restrictions. There are no daily limits on the number of files you can process and no watermarks added to your output.

Open Technology

ArmorPDF is built using well-established open-source libraries and standard web technologies. We believe in transparency: the code that processes your files runs right in your browser, where you can inspect it. This open approach means you do not have to take our word for it when we say your files stay private. You can verify it yourself.
