PNG vs JPEG Comparison
| Feature | PNG | JPEG |
|---|---|---|
| File Size | Larger (Lossless) | Significantly smaller with lossy compression |
| Transparency | Fully Supported | Not Supported (replaced by white/black) |
| Best For | Screenshots, Logos, UI Graphics | Photographs, Blog Images, Thumbnails |
| Compression | Lossless (Deflate) | Lossy (DCT-based), Adjustable Quality |
*Note: Converting PNG to JPEG will remove transparency. Any transparent areas in the original PNG will be flattened to a solid background color.
Why convert PNG to JPEG?
PNG files use lossless compression, which preserves every pixel but creates large files. For photographs and images where transparency isn't needed, JPEG provides dramatically smaller file sizes with minimal visible quality loss. Converting PNG to JPEG can reduce file sizes by 60-90%, making your web pages load faster and saving storage space.

Frequently Asked Questions
What happens to transparency when converting PNG to JPEG?
JPEG does not support transparency. Any transparent areas in your PNG will be replaced with a solid background color (typically white). If you need to preserve transparency, consider converting to WebP instead.
Will I lose image quality?
JPEG uses lossy compression, so there will be minor quality reduction. At quality settings of 85 or above, the difference is virtually imperceptible to the human eye. You can adjust the quality slider to find the ideal balance between file size and visual fidelity.
Is this conversion done online?
No. All processing happens entirely in your browser using Web Workers and WebAssembly. Your images are never uploaded to any server, ensuring complete privacy.
