Practical document tools without unnecessary friction

What we are building

The service brings merging, splitting, organizing, converting, editing, signing, reading, and image resizing into straightforward browser workflows. Each public tool is expected to perform a real task, explain its limits, and provide a usable result.

Browser-first by design

The tools currently available on PDFKaka process document files in your browser, so your documents do not need to be sent to us. If you choose phone signature transfer, only the signature image is transferred temporarily and then removed.

Processing location and limitations are described on the relevant tool and on our Security page.

Our operating principles

• Keep core tools useful without forcing an account.
• Publish a tool only when its workflow actually works.
• Use service insights to improve tools and plan future features.
• Keep the experience simple, clear, and honest.
• Improve based on reliability and real usage rather than inflated claims.
