Why Kit ?
Private by design.
Powered entirely by your device.
Every day, millions of people upload confidential agreements, financial records, personal photographs, and proprietary documents to online utility websites just to convert a format or compress a file. Most online services quietly store these uploads on remote cloud infrastructure, introducing unseen privacy liabilities and unnecessary data retention risks. Kit was created to prove that everyday digital tools should never require surrendering your personal data.
Instead of routing your files across the internet to a third party server, Kit brings the entire execution environment straight to your web browser. Utilizing modern WebAssembly binaries alongside isolated background Web Workers, your computer performs all computations locally. Whether you are editing a multi page PDF, converting video recordings, compressing high resolution imagery, or formatting Markdown notes, every single byte stays strictly contained within your device memory.
Because Kit operates entirely client side without expensive cloud rendering farms, there is no need for paywalls, subscription plans, usage quotas, or artificial file limits. You never have to create an account, manage passwords, or accept third party tracking scripts. You open Kit, complete your task at instant native speed, and close the tab with total confidence that your documents remained private from start to finish.
