Mastcall Tools is a collection of free utilities for the small jobs that come up every day: getting a photo under 50 KB for an exam form, merging PDFs for an application, converting an iPhone photo so Windows can open it.
Every tool runs entirely in your web browser. Files are processed on your own device and are never uploaded to a server, which makes the tools fast, private and usable even on slow connections.
