PDFbolt — Free online PDF tools
About PDFbolt
Learn about PDFbolt — free online PDF tools for merge, split, compress, convert, and edit.
PDFbolt is a collection of online tools for everyday PDF work, built and maintained by an independent developer rather than a large company. The goal is simple: cover the document jobs people actually need, do each one well, and keep the experience fast and free of clutter.
It is actively maintained — tools are tested, fixed, and improved over time, and new ones are added based on what people ask for. If a tool is missing or could work better, the Contact page is the quickest way to reach us, and we aim to reply within a few business days.
The tools are free to use. To cover hosting and development, PDFbolt shows advertising provided by Google. Ads are clearly labelled and kept separate from the tools, and your documents are never used for ad targeting — file processing and advertising are completely independent.
Most tools upload your file to our server, process it, and return a download. The file is used only for that single job and removed afterward — it is not stored or shared. A few tools, including Sign, Redact, and Unlock, run entirely in your browser, so those files never leave your device at all.
