Introduction

Every day, millions of people use online file converters to transform documents, images, and videos. But have you ever stopped to consider what happens to your files after you click "upload"?

The Hidden Journey of Your Files

When you use a traditional online converter, here's what typically happens:

1. Upload Your file travels across the internet to the converter's servers. This journey can be intercepted if the connection isn't properly secured.

2. Server Storage Your file is stored on their servers, often in multiple locations for redundancy. You have no control over how it's stored or who has access.

3. Processing The file is converted on their infrastructure. During this time, it exists in memory and possibly in temporary storage.

4. Lingering Data After you download your converted file, the original often remains on their servers.

Real Privacy Risks

Sensitive Document Exposure

Consider what files people commonly convert: - Tax documents - Legal contracts - Medical records - Personal photos - Business presentations

Would you hand these documents to a stranger on the street?

Data Breaches

Online converters are attractive targets for hackers because they contain high volumes of diverse, sensitive files from millions of users.

How It Works

  2. Local Loading: The file is read into your browser's memory
