Free online PDF tools that respect your privacy
PDFHook is a collection of 29 free PDF tools — including merging, splitting, compressing, signing, protecting PDFs, and converting to and from Word, Excel, PowerPoint and images — built to run entirely inside your web browser. Unlike most free PDF websites, PDFHook never uploads your documents to a remote server for processing. Instead, every merge, split, conversion and edit is performed locally using JavaScript already built into your browser.
That local-first approach means your documents stay private by default: nothing is transmitted, logged, or stored anywhere outside your own device. It also means PDFHook works instantly — there's no upload progress bar to wait through and no server queue — and it keeps working even if your internet connection is spotty, since the page only needs to load once.
Whether you need to merge a batch of PDFs into one file, remove a password, sign a contract, or convert a PDF into an editable Word document, PDFHook's tools cover the everyday document tasks people search for — all for free, with no account and no watermark.
Frequently asked questions
Is PDFHook really free?
Yes — every tool is free, with no sign-up, no daily limits, and no watermark added to your files.
Do I need to install anything?
No. PDFHook runs entirely in your web browser using standard JavaScript already built into it — there's nothing to download or install.
Are my documents uploaded to a server?
No. Every operation — merging, converting, signing, encrypting — happens on your own device. Your files never leave your browser tab.
Which file formats does PDFHook support?
PDF is supported everywhere, plus Word, Excel, PowerPoint, JPG and GIF for the relevant conversion tools.
Does PDFHook work on mobile?
Yes — every tool works in a mobile browser exactly as it does on desktop, including drag-and-drop-style file selection.
