The Problem
Every time you convert a file online, compress an image, or merge a PDF, you're trusting a stranger with your data. Most online tools upload your files to remote servers where they're stored for hours, days, or indefinitely. Some tools scan file contents for advertising. Others share metadata with third parties.
The scope of this problem is staggering. Hundreds of millions of files are uploaded to online conversion tools every month. Tax returns, medical documents, legal contracts, personal photographs, business proposals, employee records - all flowing through servers owned by companies with vague privacy policies and opaque data practices. Many of these services are free specifically because your data is the product being sold.
Even tools that claim to delete your files often retain them in backup systems, cache layers, or logging pipelines. "Deleted within 24 hours" does not mean secure. It means your sensitive document sits on someone else's infrastructure, potentially accessible to their employees, their partners, or anyone who breaches their systems during that window.
Users have accepted this as normal. We don't think it should be.
Our Approach
At topriv, we build tools that work fundamentally differently from the industry standard. Rather than trying to bolt security onto an existing cloud-processing model, we redesigned the architecture from the ground up with a single question in mind: how do we give users powerful functionality without ever having access to their data?
The answer is in-memory processing with immediate deletion. When you upload a file to PrivConvert, it is loaded into server RAM, processed entirely in memory, and the result is sent back to you. The moment your download begins, both the input and output are purged from memory. Nothing is written to disk. There is no caching layer, no backup queue, and no retention period. The data simply ceases to exist on our infrastructure.
For PrivDrop, we went even further. Files are encrypted in your browser using AES-256-GCM before they ever leave your device. The encryption key is embedded in the URL fragment, which by design is never transmitted to the server. This means our servers store only encrypted blobs that we have no ability to decrypt. It is mathematically impossible for us to access your files, even if we wanted to.
This is not privacy theater. This is privacy by architecture - systems designed so that data protection is a structural guarantee, not a policy promise.
