A random online EXIF remover receives your photo along with its location history. An online PDF service receives your passport scan and may keep it on someone else's disk. Most browser utilities make that trade silently.
CapyToolkit removes the tradeoff. It is a free collection of 45+ tools where every computation happens inside your browser: hardware diagnostics for screens, webcams, microphones, and gamepads; developer parsers for JSON, JWT, regex, cron, and SQL over local files; security utilities such as an EXIF scrubber, a PII scrubber, and offline OCR redaction; and personal tools for passport photos, PDFs, phone scans, image size limits, and receipt splitting.
There is no account, no upload, and no paywall, and the site analytics script is blocked from every tool area. Files stay on your machine and are discarded when you close the tab. It installs as an app, ships on the Microsoft Store, or just opens in a tab.
It is built for developers, security-conscious users, and anyone who needs a quick technical check or a document task without handing data to a third-party server. Every tool page includes examples and reference docs, and new tools ship regularly.
