Convert PNG to JPEG
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 JPEG conversion
- Alpha channel transparency requires background color for JPEG conversion
- DEFLATE compression reduces file size without data loss
- Supports 24-bit RGB color (16.7 million colors)
What is JPEG?
JPEG
JPEG (Joint Photographic Experts Group) uses lossy DCT-based compression, optimized for photographs with millions of colors. Supports 24-bit color depth. Quality vs size tradeoff adjustable via compression level. No transparency support. EXIF metadata for camera data. Universal web and camera format. Converting between image formats preserves or re-encodes pixel data.
- JPEG 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
Will .jpeg compression degrade my .png file noticeably?
Yes, .jpeg reduces file size through lossy compression, removing imperceptible details. However, at high bitrates (320kbps audio) or quality levels (95% images), most people cannot distinguish .jpeg from .png in blind tests. The trade-off: smaller files with minimal perceptible quality loss.
What's the batch limit for .png to .jpeg conversion?
Our free tier allows 3 .png files per batch conversion. Premium tier supports up to 20 .png files with automatic .jpeg packaging. Perfect for bulk processing.
How secure is browser-based PNG to JPEG conversion?
Extremely secure. PNG to JPEG conversion runs isolated in your browser. No network transmission, no external access, no data leakage. Perfect privacy.
Can I upload large PNG files for JPEG conversion?
Free tier accepts PNG files up to 100MB. Premium tier handles up to 500MB. Both handle typical image files. Premium ideal for large-scale JPEG conversion.
How much time does PNG to JPEG processing require?
Nearly instant for typical PNG files. Browser-based JPEG conversion processes files locally: 1-3 seconds for small files, 5-15 seconds for larger image content. No server upload—conversion starts immediately.
Do I need to install any software?
No! Everything works directly in your web browser. No downloads, no installations, no plugins required. Just upload your file and convert. Works on Windows, Mac, Linux, and mobile devices.
