When you upload a document to an online converter, where does it go? For many "free" online OCR services, the answer is a remote server. This means your bank statement, personal ID, or proprietary contract is being transmitted over the internet and processed on a computer you don't own.
The Risks of Server-Side Processing
- Data Breaches: Servers can be hacked.
- Data Retention: Some services keep copies of uploads to "train their models" or for logs.
- Man-in-the-Middle Attacks: Unencrypted transfers can be intercepted.
The Client-Side Revolution
Modern web technologies (like WebAssembly and Tesseract.js) allow powerful OCR to run directly in your web browser.
How Screenshot Clean Protects You
- No Uploads: Your image never leaves your device. The processing happens in your Chrome/Edge/Firefox memory.
- Automatic Deletion: Once you refresh, the data is gone.
- Zero Storage: We don't have a database of your images.
Before you use any tool, efficient or not, check their Privacy Policy. If they don't explicitly state that processing is local, assume your data is being sent to the cloud. Make the smart choice for your privacy.
