Most free online PDF editors require you to upload your sensitive files to their servers. This creates a privacy risk. LanaPDF is different - we use WebAssembly to process your bank statements and contracts 100% locally on your device. Your data never leaves your browser.
When you need to fill out a form or redact information from a bank statement, your first instinct might be to search for a "free PDF editor." However, many of these tools work by uploading your document to a remote server, processing it there, and then sending it back to you. This means your private financial information, addresses, and account numbers are temporarily stored on a computer you don't control.
The Risk of Cloud-Based Processing
Even if a service promises to delete your files after an hour, the simple act of transmission introduces vulnerabilities. Data can be intercepted during upload, or a server breach could expose "temporarily" stored documents.
The Local Alternative
LanaPDF takes a fundamentally different approach. We utilize WebAssembly technology to run the entire PDF editing engine directly in your Chrome browser. When you open a PDF in LanaPDF, the code comes to your data, your data doesn't go to our code.
This means minimal latency and maximum security. You can even disconnect from the internet after loading the page, and LanaPDF will continue to work perfectly. For documents containing sensitive personal information, local processing isn't just a feature - it's a necessity.
