About the PNG & JPG / JPEG Formats
PNG (Portable Network Graphics)
PNG is a raster-graphics file-format that supports lossless data compression. It was created as an improved, non-patented replacement for Graphics Interchange Format (GIF).
- Lossless compression retains perfect quality
- Supports full transparency (alpha channel)
- Excellent for graphics, text, and line art
- Significantly larger file sizes than JPG for photographs
- Does not support animation (unlike APNG which is less compatible)
- Not optimized for print graphics (no CMYK support)
JPG / JPEG (Joint Photographic Experts Group)
JPEG is a widely used lossy compression standard for digital images, particularly for those produced by digital photography. It achieves a balance between image quality and file size.
- Extremely high compatibility across all devices and browsers
- Small file sizes for photographic images
- Adjustable compression ratio
- Lossy compression degrades quality with repeated edits
- Does not support transparency (alpha channel)
- Does not support animation

Frequently Asked Questions
What happens to transparency in PNG to JPG conversions?
Since JPG does not support alpha transparency, any transparent pixels in your original PNG will be blended into a white background in the output JPG.
