FAQ

Why does converting PNG to JPG significantly reduce file sizes?

PNG uses lossless compression tailored for diagrams and graphics, while JPG uses optimized lossy compression. Converting to JPG can reduce file size by 70% or more with virtually no perceptible difference.

What happens to transparent backgrounds when converting PNG to JPG?

Because the JPEG format lacks alpha channel transparency support, transparent pixels are automatically filled with a clean white background.

Are my private PNG graphics or documents uploaded to any server?

No. All PNG decoding and JPEG encoding happen inside your browser local sandbox using Canvas. Your graphics remain entirely private on your device.
