How It Works & Features
By utilizing your browser's native capabilities, this tool provides fast, private, and secure image conversion.
- Native Re-encoding: The tool actually decodes the source image and re-encodes it using the selected format, rather than simply renaming the file extension.
- Transparency Protection: When converting transparent formats like PNG or WebP into JPEG (which does not support transparency), you can pick a specific background color to properly fill the empty areas instead of getting unexpected black artifacts.
- Browser-side Privacy: We use native image rendering and canvas features running directly in your web browser. This ensures no data transfer, instant speed, and absolute privacy.
