What is the JPEG format
JPEG is a standard image file format used to contain lossy images.
It was developed by the Joint Photographic Expert Group and released in 1992. It's the most used image format worldwide.
What are the advantages and disadvantages of the JPEG format?
The JPEG format is the international standard for lossy compression in images. It has several advantages that gave it such status. However, the format is not perfect, and it has its drawbacks. Those are:
- JPEG compression can reduce data size up to a factor of ten. That makes JPEG files considerably smaller than uncompressed images.
- It's been a standard image format since the 90s. All devices can open JPEG files. Even old computers, phones, and software support JPEG images.
- JPEG images have a wide range of colors.
- Despite the high compression, JPEG images still maintain acceptable quality.
- Its quality is lower than uncompressed image format due to lossy compression.
- It doesn't allow transparent backgrounds.
- It doesn't support layered images.
- It's not a good option if the images have text.
JPEG Format FAQs
Is JPEG and JPG the same?
JPG and JPEG are interchangeable terms and refer to the same format. They are synonyms.
The JPG name for the format comes from the JPEG filename extension, which usually is .jpg. But it can also be .jpeg, showing no differences between the two. You can even rename .jpeg to .jpg without changing the files themselves.
How does the JPEG work?
The JPEG reduces data size using lossy compression. That method of compression discards imperceptible data parts, making the file smaller. The parts are permanently removed from the file, or lost in other words. This allows JPEG files to be considerably smaller than most image formats.
JPEG format allows you to decide how much data you want to compress. As a result, JPEG files can have variable sizes and quality.
Is JPEG better than PNG?
JPEG is better or worse than PNG, depending on your needs.
In terms of quality, the PNG format is better than JPEG. It uses lossless compression, and no data is lost in the process. That means the image quality is as high as it was initially, with no loss.
JPEG beats PNG when it comes to saving space storage and image distribution over the Internet. JPEG images are about five times smaller, making them easier to load when browsing. JPEG also has more adoption than the PNG format.
