Your Files Belong to You. Period.
Offline99 was created with a simple promise: to give you simple, powerful tools to edit and compress your media without ever uploading your personal files to the internet.
Why Offline99 is Different
Most websites that compress videos or edit PDFs ask you to upload your files to their servers. This means your personal photos, private work documents, and voice recordings travel across the internet and sit on someone else's computer.
Offline99 works completely differently. When you open our website, your web browser turns into a self-contained workstation. All the editing, cutting, and shrinking happens directly inside your web browser on your own device.
