JPEG Image Conversion and Viewers
Snowbound's imaging products enable you to specify image quality and compression when converting to JPEG. Companies commonly use JPEG compression for storage and Web compatibility.
What Is the JPEG Format?
JPEG (.jpeg, .jfif, .jpg and .jpe) is a standard image compression format developed by and named after the Joint Photographic Experts Group. It is one of the two most common formats for storing and sending images on the Web. JPEG images are full-color images, meaning they are capable of storing 24 bits-per-pixel and using 16 million colors. JPEG is best for compressing full-color or gray-scale images, including photographs and graphic images.
The JPEG format is unique in the aspect that images are compressed based on the human eye. Because the human eye does not pick up subtle color distinctions and high frequency brightness variations, data can be removed without completely changing the image. However, as this data is removed the quality of the image decreases. This is the reason JPEG compression is considered “lossy”.
As with all image compression formats, JPEG has both its advantages and disadvantages:
Advantages of the JPEG Format
- Large compression ratios = shorter file transfer time
- Full-color information
- Great for photographs, graphic artwork, banner ads, etc.
Disadvantages of JPEG Format
- Loss of image quality
- Sharp edges tend to come out blurry
- Longer page load time than the GIF Format
History of JPEG
The Joint Photographic Experts Group was formed in 1986 as a joint committee between the International Standards Committee and the ITU Telecommunication Standardization Sector. The JPEG standard was established in 1992 as a means of adding photos to text terminals and was approved by the group in 1994.
In 1993 the group developed Lossless JPEG using a different algorithm to try and preserve image quality while still reducing the size of the image. Two other standards were later introduced, JPEG2000 and JPEG-LS. These two compression methods were both developed to be lossless/near-lossless as well. Currently JPEG remains the most popular format of the three.

Important: As we all know document and image specifications are intentionally loosely written and rarely updated. As a result many applications create documents “incorrectly” and they do not adhere to the latest specifications.
In order to maintain the highest ethical standards and help provide customers with the most positive user experience, Snowbound Software recommends that, as part of your purchase process, you test your own sample documents against our products. Snowbound, unlike most competitors, develops its own technology. If in the rare case you come across a problem or non-conforming document or image, we can often fix it.
