JPG or JPEG Files
JPG iss a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality. Since its introduction in 1992, JPEG has been the most widely used image compression standard in the world, and the most widely used digital image format, with several billion JPEG images produced every day as of 2015.
What is JPG file ?
A JPG is a type of image format that is stored using the technique of lossy compression. The output picture, as result of compression, is a alternate-off between storage length and photo great. customers can regulate the compression stage to acquire the desired satisfactory degree at the same time as on the same time reduce the storage size. photograph exceptional is negligibly affected if 10:1 compression is carried out to the photograph. The higher the compression price, the better the degradation in image first-class.
JPG file format specifications.
JPEG photo document layout become standardized through the Joint Photographic experts institution and, for this reason, the call JPEG. The format has been the choice of storing and transmitting photographic pics at the net. nearly all running structures now have viewers that assist visualization of JPEG snap shots, which are frequently saved with JPG extension as well. Even the internet browsers aid visualization of JPEG pics. earlier than going into the JPEG report format specifications, the overall system of steps worried in JPEG advent want to be noted.
JPG vs JPEG: Similarities Between the Two
Okay, so you know that .jpeg and .jpg files are the same exact thing. But just to drive that point home, and help you remember it long into the future, we’re going to look at the similarities of JPEG and JPG images.
1. Both Are Raster Images (Not Vector Images)
Computer images can be created as raster or vector images. And since JPEGs are raster images, so are JPGs.
Raster graphics are bitmaps of images. A bitmap is a grid of individual pixels that when combined create an entire image. In other words, raster images are a collection of countless tiny squares (or pixels) of color that are each coded in a specific hue or shade that when put together create a whole image that makes sense to look at.
Here’s more information about raster images to help you better understand:
- Best used for non-lined images such as photographs, scanned artwork, or detailed graphics.
- They have subtle hue or shade gradations and very undefined lines and shapes.
- Due to their pixel-based nature, they suffer quality issues when blown up in size (they become jagged and expose individual pixels).
- They are defined and displayed at one specific resolution, which is measured in dots per inch (dpi).
- The higher the dpi, the better the resolution and visual appeal of the image.
- Common raster file formats include: TIFF, JPEG, GIF, PCX and BMP files.
- Raster images are the Web standard, meaning they are preferred for all images found on the internet.
Again, JPEGs and JPGs are not vector images.
2. Both Terms Mean the Same Thing
Remember when we discussed the term JPEG and how it stood for the Joint Photographic Experts Group? Well, you guessed it; both JPEG and JPG are abbreviations for that same ISO sub-committee.
3. Both Are Used for the Same Image Types
Because they are raster images, and not vectors, both .jpeg and .jpg file formats are best used for digital photography. Digital photographs have extensive color gradations that appear seamless when saved as raster JPEG/JPG images. This means your site visitors will always see a beautiful photograph if it’s saved as a .jpeg/.jpg and uploaded to your website.

4. Both Lose Some Quality When Saved
Since the .jpeg vs .jpg comparison is null (because they are the same exact thing), it makes sense that the compression method used on each file format — lossy compression— results in some loss of image quality as the file size of the image decreases.
In addition, this means that no matter what file extension you use (either .jpeg or .jpg), your image’s file size will be smaller than it was originally and result in faster loading times when uploaded onto your website and viewed by site visitors.
In the end, JPEGs and JPGs are the same thing and serve a few main purposes: to reduce the file size of images for better web viewing and give people an easy way to compress their images upon saving and name the file using a common file extension that is recognized by many.
So ask yourself: JPG vs JPEG, which is better? From there, don’t think too hard because the answer is neither. They are the same and whichever one you choose, is just a matter of preference.
