Secure PDF Tools That Don't Upload Your Files
The problem: Most PDF tools upload your files to their servers. For sensitive documents — contracts, medical records, financial statements — this is a serious privacy risk. DocMint solves this with 100% browser-based processing.
The Risk of Uploading PDFs to Online Tools
When you use a typical online PDF tool, your file travels from your device to their servers, gets processed, and then gets sent back. During this process:
- Your file is transmitted over the internet (even with HTTPS, it reaches their servers)
- The service stores your file temporarily (sometimes longer)
- Server breaches could expose your documents
- Some services scan files for advertising or training AI models
