Why JPG-to-PDF Converter on sakutto is safe
Many online tools upload your files to external servers for processing. This tool never sends your image files to any server — everything is processed entirely in your browser.
* Some AI-powered tools require server-side processing. Tools that send data to a server will always notify you beforehand.
| Comparison | Typical online tools | sakutto |
|---|---|---|
| Where data is sent | Uploaded to external servers | Nowhere — processed in your browser |
| Data leak risk | Risk during transfer and server storage | No risk — no network transfer occurs |
| External traffic | File data travels over the internet | No file data appears in network logs |
| Offline use | Not possible (server required) | Works offline after initial load |
How browser-based processing works
- WebAssembly (WASM): Processes image files in your browser at near-native speed. No server communication occurs.
- Web Workers: Runs on a background thread separate from the main thread, so your browser stays responsive during processing.
- After processing, your browser automatically frees the data from memory. No image files remains outside your device.
For IT security teams: How to verify
You can verify that sakutto never sends your image files externally by checking the Network tab in your browser's DevTools while using the tool. You'll see that no requests involving your image files are made. This can also serve as documentation for your IT security team.
