100% Private: No File Uploads
Your images often contain personal photos, proprietary designs, confidential screenshots, or sensitive visual data. Uploading these to a cloud-based converter exposes them to third-party servers where they might be stored, logged, or accessed by unauthorized personnel. Our tool eliminates this risk entirely. The conversion uses your browser's native Canvas API and FileReader API — everything runs in client-side JavaScript. You can verify this by checking the Network tab in your browser's DevTools during conversion. You will see zero outbound requests. For maximum confidence, you can even disconnect from the internet after loading the page and the conversion will still work perfectly.
