Convert PNG to JPG
What is PNG?
PNG
PNG uses lossless Deflate compression, preserving exact pixel values without quality loss. Supports full alpha channel transparency (256 levels) unlike JPG. Ideal for graphics with sharp edges, text, logos, or images requiring transparency. Typically larger file sizes than JPG for photographs due to lossless compression. Maximum resolution 2,147,483,647×2,147,483,647 pixels. Supports indexed color palettes and metadata chunks.
- PNG uses lossless compression for perfect quality image storage
- Lossless source ensures maximum quality for JPG conversion
- Alpha channel transparency requires background color for JPG conversion
- DEFLATE compression reduces file size without data loss
- Supports 24-bit RGB color (16.7 million colors)
What is JPG?
JPG
JPG uses lossy DCT compression with 8×8 pixel blocks, ideal for photographs with smooth color gradients. Compression ratios range from 10:1 to 20:1 depending on quality settings. Maximum resolution 65,535×65,535 pixels. No transparency support (unlike PNG). Supports EXIF metadata for camera information. Best for photographs; poor for graphics with sharp edges, text, or solid colors due to compression artifacts.
- JPG uses lossy compression for efficient image storage
- Lossy compression means conversion to PNG preserves but cannot restore quality
- Opaque image data converts to PNG without utilizing transparency features
- DCT-based compression removes high-frequency visual data
- Supports 24-bit RGB color (16.7 million colors)

Frequently Asked Questions
What happens to transparency when converting PNG to JPG?
JPG doesn't support transparency. Transparent areas become white (or you can choose a background color). If your PNG has transparency, consider keeping it as PNG or use a format that supports transparency.
How much smaller will my JPG be compared to PNG?
Typically 50-80% smaller. A 5MB PNG might become a 1-2MB JPG. Exact savings depend on image content and quality settings. Photos compress well, graphics with solid colors less so.
Should I convert PNG to JPG for my website?
For photos: Yes. JPG is smaller and loads faster. For logos/graphics with transparency: No, keep PNG. For graphics without transparency: Test both - sometimes PNG is smaller for simple graphics.
