Anyone who uses Photoshop or any image editing software must have close association with JPEG files. Any sort of image that is intended for web or print purpose will mostly be saved in this format. It is an easily accessible format that requires very less loading time when compared with other formats like PNG. There are several myths around this particular file format which is so much handy and used by professional and amateurs alike… Let’s take a look at the top Myths and Facts on JPEG
1. JPEG is the proper spelling:
The very first fact we would like to talk about is the correct spelling of this acronym. Though the file extension while saved spells as JPG, the actually spelling is JPEG. To be even more precise we would like to expand the acronym in order to support our point which is ” Joint Photographic Experts Group”- the organization that developed the JPEG format.
2. JPEGs lose quality every time they are opened or saved:
This is a false statement and has no grounds to be proved right. It is worthy to note that JPEG files do not lose its quality while saving or opening repeatedly. This concept was weaved as some image editors do re compress JPEGs when the Save As command is used and as a result the files lose their quality. If you intend to overcome this flaw, you may simply you should duplicate and rename JPEGs in a file manager and don’t use the Save As option in the editing program. Therefore viewing or saving does not harm the file under any circumstances.
On the other hand, weather it is a simple background removal or a complex image editing process like color correction, it is important to remember that it is very important to minimize the editing sessions between the initial and final version of a JPEG image to make sure that they don’t lose quality every time they are opened, edited and saved.
3. A quality setting of 100 does not degrade an image at all:
While we save an image in JPEG format, it brings in certain amount of quality loss. Although the loss at a quality setting of 100 is hardly measurable or noticeable in naked eye, we have to admit that the statement is true to the fullest. To see a visible difference that you may easily identify try to save many copies of an image at 90, 95, and 100 quality, now evaluate the quality of the image file size with image quality. JPEG formats are normally skipped while we need precise color matching.
