Problem
Traditional PDF tools require users to upload sensitive documents—contracts, invoices, medical records—to cloud servers, creating privacy risks and necessitating accounts, subscriptions, or large software installs. Users face friction from signup requirements, file size limits, and uncertainty about what happens to their data after upload.
Solution
Mudra provides a fully in-browser PDF editor that processes all files locally on the user's device, with zero bytes transmitted to any server. Users can upload a PDF via drag-and-drop, then add text, highlight, draw freehand, or sign with a mouse or touchscreen—all without creating an account or installing software. The tool works in any modern browser, functions offline after the first load, and includes collaboration-style annotation features. A free tier supports files up to 10 MB, while paid plans add larger file handling, cloud storage, and team features. The interface is designed for speed, with typical signing workflows completed in under a minute.
Target Audience
Primary users are individuals who need to occasionally sign or annotate PDFs—such as freelancers, independent contractors, and everyday consumers—plus professionals and teams who require larger file support, cloud save, and collaboration tools.
