About PNG to JPG Conversion

Why Convert PNG to JPG?

JPG (JPEG) uses lossy compression that significantly reduces file size compared to PNG, especially for photographs and images with smooth color gradients. This makes JPG ideal for web usage, email attachments, and storage optimization where smaller file sizes are more important than perfect quality preservation.

Understanding JPG Quality Settings

The quality slider controls the compression ratio of the JPG output. At 100%, minimal compression is applied, preserving most detail but with larger files. At lower settings (60-80%), significant size reduction is achieved with minimal visible quality loss for most photos. Settings below 50% may show noticeable compression artifacts.

Transparency Handling

JPG format does not support transparency (alpha channel). When converting PNG images with transparent areas, those areas are automatically filled with a white background. If you need to preserve transparency, consider keeping the image in PNG or WebP format instead.

Privacy & Security

All image processing happens entirely in your browser using HTML5 Canvas API. No files are uploaded to any server, ensuring your images remain completely private. The tool works offline once loaded, making it safe for sensitive or confidential images.
