## Detailed info

## What is Private Toolkit?

Private Toolkit is a collection of file and text conversion tools developed by Gyrus Solutions. It executes entirely inside the user's web browser using JavaScript and WebAssembly modules without uploading files to remote servers.

## What Private Toolkit does

The toolkit provides four client-side workbenches: Image, Video, Text, and Archive. It converts photos across formats including HEIC, camera RAW, WebP, AVIF, PNG, and TIFF, returning batch results in a single ZIP. The video tool rewrites clips into MP4 containers, compresses files to target limits, and generates GIFs. It also cleans OS metadata like .DS_Store and Thumbs.db from ZIP archives, and formats text, JSON, YAML, HTML, and XML.

## Who Private Toolkit is for

The utility is designed for users working with sensitive photos, private documents, and media who need format conversion without sending files to third-party servers.

## How Private Toolkit works

Users select or drop files and folders into their browser, where client-side WebAssembly encoders process the data directly on the local processor, enforced by Content Security Policy restrictions.
