ABOUT
About
OKURAZU is a local file toolkit: the images and PDFs you select are processed inside your own browser and are never sent to an outside server.
About the service
OKURAZU is free to use. The release version, the bundled libraries and the known limitations are recorded in the README and in the third-party licence notices.
Design principles
No analytics, advertising, external APIs, CDNs or external fonts are used. A new feature is only released once on-device processing and its safety have been confirmed.
