About CapyToolkit

CapyToolkit is a growing collection of free, privacy-first browser tools. Most online utilities upload what you type, paste, or record before showing a result; these 50+ tools compute on your device instead. The catalog includes a gamepad drift tester, mouse polling rate meter, speaker sweep, JWT decoder, EXIF scrubber, passport photo cropper, PDF toolkit, and receipt splitter. Nothing is sent to a server, no account is needed, and it stays free. Also on the Microsoft Store.

Who is CapyToolkit for?

Indie makers, early adopters, PC builders, streamers, and everyday users who need a fast hardware check, a PDF fix, or a passport photo.

How does CapyToolkit work?

CapyToolkit is a growing collection of free, privacy-first browser tools, built by a solo developer tired of tools that demand uploads and signups. Hardware testers, dev parsers, security scrubbers, audio checks, and PDF and photo tools all run client-side.
