How to Use (Easy Steps)
1. Upload your PNG files. 2. Adjust the 'JPEG Quality' slider. 3. Pick a 'Transparency Fill' color (replaces alpha). 4. Click 'Execute Elite Convert' and download your optimized JPGs.
Intelligent Flattening
Since JPG doesn't support transparency, our engine allows you to pick a custom fill color (defaulting to clean white). This ensures that transparent logos or icons looks professional on a solid background.
Quality Orchestration
Our 'HD Elite' compression algorithm prioritizes structural integrity over file size at higher settings, or provides aggressive size reduction for web deployment when moved to 'Balanced'.
Privacy Fortress
All processing happens in your browser's local sandbox. Your files are NEVER uploaded to a server, making this the safest way to handle proprietary screenshots or personal data.
Frequently Asked Questions
Why do I need to pick a background color?
PNG files can be transparent, but JPG files MUST have a solid background. By providing a color picker, we give you full control over how your transparent areas are filled.
Is there any quality loss?
JPG is a lossy format by nature. However, at 90-100% quality, the difference is virtually imperceptible to the human eye while still reducing file size significantly compared to PNG.
Can I convert high-res screenshots?
Absolutely. Our engine is optimized for high-resolution graphics, though very large batches (20+) may depend on your device's available RAM.
