Technical Details & Specifications
Our image converter is built with performance, quality, and privacy in mind. Here's what makes it stand out from other conversion tools:

Transparency Handling
When converting to JPG (which doesn't support transparency), you can choose a background color for transparent areas. The color picker allows you to select any color, ensuring your converted images look exactly as intended.
Performance Optimization
Batch processing handles multiple files efficiently with progress tracking. Conversion speed depends on image dimensions and your device's CPU. Most images convert in under 2 seconds on modern devices.
