What it does
The Image to JPG Converter lets you change HEIC, WebP, PNG and other formats to high‑quality JPG files directly in your browser. All processing happens on your device, so no data is sent to a server and there are no watermarks or usage limits. Adjustable compression lets you balance file size and visual fidelity while keeping detail and colour depth intact.
Your files stay yours

- All conversions occur in the user's browser with no file uploads or cloud storage.
- Browser-Only Architecture: All processing occurs locally, ensuring no data is transmitted to servers.
