JPEG: The Photo Format That Changed the Way We See Pictures
Published on:
Introduction
JPEG stands for Joint Photographic Experts Group. It is a popular format for storing and sharing photos. JPEG makes images small in file size while keeping them clear and colorful.
How It All Began
In the 1980s, experts from around the world came together with one goal: to create a method to reduce the size of digital images. In 1992, they released the JPEG standard, making it easier to save, share, and display photos on computers and phones.
How JPEG Works
JPEG uses a method called lossy compression. This means it removes some details from an image to save space. The details removed are usually not noticed by the human eye, keeping the file small while still looking good.
Key Features of JPEG
- Efficient Compression: JPEG files are much smaller than raw images. This saves storage space and speeds up sharing.
- Rich Colors: It supports millions of colors, making photos vibrant and realistic.
- Wide Compatibility: Almost every device and web browser can open JPEG images.
- Adjustable Quality: You can choose the level of compression. Higher quality means a larger file, while more compression means a smaller file.
When to Use JPEG
JPEG is best for photographs and images with smooth gradients. It works well for colorful and complex pictures. If you need sharp lines or clear text, formats like PNG may be a better choice.
The Legacy of JPEG
Today, JPEG is one of the most used image formats in the world. It has made sharing photos online fast and easy. Even with new image formats emerging, JPEG remains a trusted choice because of its simplicity and efficiency.
