vupdf brings the PDF jobs people run into every day together in one place: merging and splitting files, shrinking a scan so it fits in an email, turning a Word document into a PDF or a PDF back into an editable file, adding a signature, a watermark or page numbers, and locking a document with a password. Every tool opens straight in the browser, so it works the same on Windows, macOS, Linux, Android and iPhone.
There is no account to create and nothing to install. You pick a file, check the settings and download the result, usually within a few seconds. Each tool has its own page that explains what it does, how to use it, what its options mean and where its limits are, so you know what to expect before you upload anything.
Choose a tool from the list above, or use the categories to narrow it down.
Drag your file onto the page or click to select it, then adjust the options the tool offers, such as page ranges, quality or a password.
Start the job and download the result. Use "New task" to start again with another file.
Uploaded files are used only for the job you asked for and are deleted from the server as soon as the result has been delivered to you. An automatic clean-up removes anything left over from an interrupted job within an hour. We do not look at your documents, keep copies of them or use them to train AI, and they are never used to target ads.
