Free Online PDF Tools — No Uploads Required
InBrowserApp offers a complete suite of PDF tools that run entirely inside your web browser. Whether you need to merge several documents, compress a large file for email, rotate a misfed scan, or extract text from a scanned PDF using OCR, every operation is performed locally on your device using modern JavaScript and WebAssembly. Your files never leave your computer.
Why Use a Browser-Based PDF Tool?
Traditional PDF software requires installing a desktop application — often expensive, tied to a single operating system, or bloated with features you do not need. Online PDF services require you to upload your documents to a cloud server, which raises privacy and security concerns for sensitive business, legal, or personal files.
Browser-based PDF tools solve both problems. They run on any operating system, require no installation, and process your files locally. There is no upload step — files are read directly from your device into your browser's memory, processed, and downloaded back to your machine. Nothing is stored or transmitted.

Privacy & Security
All PDF processing on InBrowserApp uses client-side libraries including pdf-lib (for PDF creation and manipulation), PDF.js (for rendering), and Tesseract.js (for OCR). None of these libraries communicate with a remote server. When you load and process a PDF, the file contents exist only in your browser's memory and are discarded when you close the tab. We do not log, store, or have access to any of your documents.
