PNG supports transparency, allowing you to place images over any background without a white or colored box around them.

About the JPG Format
JPEG is the most widely used image format on the internet. It uses lossy compression, which means it reduces file size by discarding some image data that the human eye is unlikely to notice. This makes JPEG ideal for photographs and complex images with many color variations. However, each time you save a JPEG, it loses a small amount of quality — this is known as generation loss. JPEG does not support transparency or animation.
The JPEG format was created in 1992 by the Joint Photographic Experts Group. It quickly became the standard for digital photography and web images due to its efficient compression and universal browser support.
✅ Advantages
- Extremely small file sizes for photos
- Universal support across all devices and browsers
- Adjustable compression quality
- Ideal for photographs and complex images
❌ Disadvantages
- Lossy compression — quality degrades with each save
- No transparency support
- No animation support
- Not ideal for text, line art, or sharp edges
About the PNG Format
PNG is a lossless image format that preserves every pixel of your image perfectly, no matter how many times you save it. It supports full alpha transparency, making it the go-to choice for logos, icons, and any image that needs to be placed over different backgrounds. PNG files are typically larger than JPEG files for photographs, but they excel at preserving sharp edges, text, and flat-color graphics.
PNG was developed in 1996 as a patent-free replacement for the GIF format. It was designed to improve upon GIF by offering better compression, true color support, and full alpha transparency.
✅ Advantages
- Lossless compression — no quality loss
- Full alpha transparency support
- Perfect for screenshots, logos, and graphics
- Sharp text and edge preservation
❌ Disadvantages
- Larger file sizes than JPEG for photographs
- No animation support (use APNG or GIF instead)
- Overkill for simple photographs where lossy is acceptable
