5 Tools for JPEG Image Compression
On most occasions, we need to compress images for different reasons, such as smaller images on the website for faster loading and emails attaching more images under file attachment limitation. And JPEG is usually the welcomed image format as JPEG image compression can balance size and image quality, providing a better user experience.
What is JPEG?
JPEG, which stands for Joint Photographic Experts Group, is the most common image format with the extension .jpeg or .jpg. It is an image format with lossy compression, meaning it cannot maintain high-quality images while keeping a small size. However, you can adjust the compression level to reach the desired size and keep it at a relatively high quality simultaneously. The higher the compression percentage, the lower the image quality will be. And when you compress jpeg images within a 10:1 ratio, it would not affect the image quality.
Three Types of JPEG Formats:
This format gradually shows images from top to bottom during webpage downloading. You cannot view the image until all data is completely downloaded.
During webpage downloading, this format displays an indistinct shape of images and gradually shows the complete content. It is smaller than the standard JPEG format, making it ideal for website uploads.
It is a new-generation image compression method that offers higher quality and can correct mosaics and dislocation caused by poor signals during wireless transfer, improving image quality.
The Pros and Cons of JPEG Images
