About Toolkase

Toolkase is a free toolbox of browser-based utilities for PDFs, images, text, generators, and developers.

Our wedge is simple: your files never leave your device. File tools read and process data locally in your browser. We don’t run upload pipelines, and we don’t keep a copy of your documents.

That means fewer privacy tradeoffs, fewer accounts, and tools you can use for quick jobs without sending sensitive material to a third-party converter.

We’re shipping in waves — starting with high-intent tools like PDF Merger, Image Compressor, and JSON Formatter.
