When you upload a document to an online converter, where does it go? For many free services, the answer is a remote server. That means your bank statement, personal ID, or proprietary contract is transmitted over the internet and processed on a computer you do not own.
The Risks of Server-Side Processing
- Data breaches: Servers can be hacked.
- Data retention: Some services keep copies of uploads for logs or training.
- Man-in-the-middle attacks: Unencrypted transfers can be intercepted.
The Client-Side Approach
Modern web technologies like WebAssembly allow OCR to run directly in your web browser.
How Screenshot Cleaner Protects You
- No uploads: Your image stays on your device.
- Automatic cleanup: Data disappears when you refresh the page.
- Zero storage: We do not keep a database of your images.
Before you use any OCR tool, check the privacy policy. If it does not explicitly say processing is local, assume your data is sent to the cloud.
