About grumpes
grumpes is a collection of free, fast and genuinely private tools for working with PDF and document files. It was built around one simple idea: the everyday jobs of converting, merging, splitting and compressing documents shouldn't cost money, require an account, or force you to hand your private files to a stranger's server.
What makes us different
Most online PDF tools upload your files to a remote server, process them there, and send them back. That means your documents — which often contain personal, financial or confidential information — leave your control.
grumpes works differently. Every tool runs entirely inside your web browser. Your files are processed on your own device and never travel across the internet to us. We couldn't see your files even if we wanted to, because they never reach us. This also makes the tools fast: there's no upload wait and no queue.
Our tools
- Word to PDF — convert DOCX documents into clean, properly formatted PDFs.
- PDF to Word — extract editable text from a PDF into a Word document.
- Image to PDF — turn JPG and PNG images into a single PDF.
- Compress PDF — reduce file size for easier sharing and uploading.
- Merge PDF — combine several PDFs into one document.
- Split PDF — extract pages or separate a PDF into multiple files.
Who builds this
grumpes is an independent project run by a solo creator who was tired of paywalls, watermarks and sketchy "free" converters. The goal is to keep the core tools free forever, supported modestly by unobtrusive advertising, while never compromising on the promise that your files stay private and on your device.
