Convert JPEG to PNG
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)
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)
Why Convert JPEG to PNG?
✓ Enhanced Software Compatibility
PNG eliminates the compatibility limitations of JPEG. Images display reliably on Windows, Mac, Linux, Android, iOS, and every major software platform without version restrictions.
✓ Prevent Further Quality Loss
JPEG already uses lossy compression. Converting to PNG prevents additional degradation during editing or re-encoding, preserving the current quality level for further processing.
✓ Add Transparency Support
PNG supports alpha channel transparency, enabling transparent backgrounds for logos, graphics, and design elements—essential for layering images over varied backgrounds in web and graphic design.
✓ Simplified Sharing
PNG format simplifies file sharing via email, cloud storage, and collaboration platforms with guaranteed recipient access and consistent display across systems.

Frequently Asked Questions
Can .png recover detail removed by .jpeg compression?
Unfortunately no. JPEG uses lossy compression that permanently removes information. PNG stores the current state losslessly, preventing additional degradation during future edits, but cannot recover data .jpeg already discarded during its compression.
Does batch processing work for JPEG to PNG conversion?
Absolutely. Select multiple JPEG files when uploading. Free accounts process 3 files per batch, Premium handles 20 files. All .png outputs download as individual files or combined ZIP archive.
Is my JPEG data secure during conversion?
Absolutely secure. JPEG files process entirely within your browser. No data leaves your computer—no uploads, no tracking, no external processing. Your PNG files generate locally.
How big can my JPEG file be?
Free accounts: 100MB maximum. Premium accounts: 500MB maximum. Typical image files convert easily. Upgrade Premium for larger JPEG to PNG conversions.
How quickly will my JPEG file convert to PNG?
Very fast! Small JPEG files (under 5MB) convert to PNG in 1-3 seconds using browser processing. JPEG files up to 20MB typically complete in 5-10 seconds. Processing happens directly on your device—no upload delays.
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.
