Generally yes, the JPEG algorithm uses a lossy compression, so minor image details are lost. For more details about the JPEG algorithm visit the related link.

What compression formats are used for image?
Compression methods are used for images compression and most common compressions are JPEG which is lossy (you can lost some details or quality of image), LZW which is lossless, RLE and ZIP also lossless compressions.
What is the advantage of jpeg?
JPEG images (jpeg, jpg) use compression formats to reduce the data file size for digital images. While this causes a loss of image quality, it enables images to be more efficiently stored and transmitted.
How do you turn an JPEG image into a jpg image?
JPEG is the same as JPG. However if you really want to rename your .jpeg images into .jpg, you can go to Command Prompt, navigate to the folder of where your pictures are stored, and type in: ren *.jpeg *.jpg
What would the difference between a GIF and a JPEG image be?
There are multiple differences between GIF images and JPEG images. One main difference is that a GIF may show an animation, while a JPEG is simply one still picture.
Why lossy compression is used for JPEG image?
The JPEG format was specifically designed to minimize the size of the file beyond what other formats were able to do at that time (for example BMP RLE or GIF LZW). In order to achieve it, it was decided to accept minor degradation of the image quality - with other words the compression is lossy. For more details about how the JPEG format compares to other image formats, please see the related question.
Can JPEG images be converted to gif?
Just open the jpeg image in photo shop and go to menus : file --> save for web and devices. A save for web and devices window will open, set its extension to gif then click on save button. It will save your jpeg image to gif image. Cheers
What is a jpeg image?
The JPEG/EXIF file format is optimized for storing images like photographs. It uses lossy compression, RGB, 8 bit per channel, no support for transparency or multiple images, 2D images support. The files are small and as long as the compression is not too great the image quality is almost identical to the original.JPEG images are very common, being supported virtually by every imaging device and image processing software. Due to their small size are ideal for storing, transmitting and embedding photos or similar images.
Why gif is best for cartoon images not JPEG?
GIF are images that are moving, aminated. While JPEG images are still.
What file formats is best used for small size photographic images?
Stick to JPEG it compresses the image slightly and is a very popular format for small images
How many 10.1 megapixal images can a 2GB memory card hold in a digital camera?
Depends on the jpeg image compression. Can vary from around 300 to 1000 but the more images it can store the worse the picture quality. Varies with model of camera, check the instruction manual.
Why images same resolution different size?
I assume we are talking here about JPEG images. The reason is very simple, the final size of the JPEG depends on the compression ratio, other JPEG parameters and the image content itself. Therefore in digital cameras for example they trade image size for speed using a weaker compression scheme, while personal computer programs use more complex algorithms obtaining better image sizes.
What is an animated JPEG?
Animated JPEG are multiple single jpeg images that is runned under a javascript which runs the jpeg like a animated GIF, by frames of each images.
