Privacy by design

Your work files
stay with you.

Our offline tools process files locally instead of sending them to a web service. That makes them a practical choice for client data and internal documents.

  1. 01
    No uploads

    Your files are processed locally and never sent to our servers.

  2. 02
    No account

    We do not ask for your email address or a user registration.

  3. 03
    No subscription

    Use the tools you download without another monthly bill.

FAQ

Good to know

Are these tools really free?

Yes. Every tool listed here is free to download. Optional contributions help fund future development and maintenance.

Do you receive the contents of my files?

No. The offline version processes files on your device without uploading them to an external server.

How are download counts measured?

The download endpoint adds one to an aggregate total for the selected tool. The counter stores no cookie, account, filename, or tool input, and the offline tools themselves contain no analytics.

Will you add more tools?

Yes. We plan to keep adding small, practical tools for file management and everyday office work.
