PDkef started with an ordinary errand. My partner needed to download all her course slides into a single PDF before an exam, and separately needed to sign a summer-camp consent form that had arrived over WhatsApp. We went looking for tools to do both. One capped the number of pages you could merge. One wanted a paid subscription plus a Windows install. One just felt like a place you would not want to send a personal document. So I built the tool I wanted for myself, and named it PDF + kef ("fun" in Hebrew) = PDkef.
I believe simple tools like these should be free and accessible to everyone, everywhere, on any device. That is the whole reason PDkef exists: I wanted it for myself, and then I wanted to share it, so it saves other people the same time and hassle instead of sending them to a paywall or a site they have to trust with a personal document.
What PDkef does
PDkef is a suite of PDF tools, sign and fill, merge, split, compress, edit pages, convert to and from images, redact, and unlock or protect, that all run inside your browser. There is no upload step and no server that processes your file: the code that reads and changes your PDF runs on your own device, the same way a desktop app would, except you do not have to install anything.
Every tool is free, with no account, no page limit, and no watermark. The Sign tool also supports typing in 20 languages and scripts, including Hebrew, Arabic, Hindi, Bengali, Tamil, and Thai, and can save a draft on your own device so you can pick up a form later even if the tab closes.
Who built it, and how it stays trustworthy
PDkef is built and maintained by Shlomi Shemesh. The entire codebase is open source on GitHub under the MIT license, so nobody has to take the privacy claims on faith: anyone can read exactly what runs on their device, including the parts that handle your file.
