No, but if they are converted to much by programs they can loss their quality. If you want a much better quality, look into png.

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.
Image files that are repeatedly compressed by the JPEG algorithm suffer visible quality degradation?
There are some opinions that this is the case (see the link "JPEG Image Compression Degradation"), but I cannot agree. Normally there is no major degradation of the image by repeating the open/save jpeg operation again and again. The reason is the after the first compression step, the image colors are shifted to improve the jpeg image. After the second open the colors are already very close to the jpeg compressed data and there will be no significant change anymore. There are minimal differences, but this is it. Even with 5% quality, the output image quality remains stable. The file size remains also stable.
How do you transfer a wps document to a JPEG?
Open the document in PAINT and then save it as a jpeg image. It will not be very good quality most of the time but it works!
Does converting a raw image after processing to jpeg make it lose it's quality Therefore negating the point of shooting in raw?
JPEG is not a loss less image format. When it is copied, it starts to degrade.
What is the best image compressor for making image files smaller?
Depends for what the image is going to be used. If it's for a high resolution printing such as print ad in a magazine or poster TIFF format with LZW is preferred for quality purpose. JPEG format gives more options for compressing an image, especially for web usages or not for high quality printing purpose. Also it depends on the original image quality and resolution, if the quality of the original image is good, then JPEG will be a good option to use.
How large can a 2.37MB JPEG file be enlarged?
There is no upper limit when enlarging an image. The limiting factor is the quality loss. When enlarging you will always loose quality. Note: the filesize for a JPEG does not tell much about it since JPEG uses a lossy compression algorithm - i.e. the resulting file size is depending a lot on the original image and the compression level.
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.
When a JPEG file format is comprised what happesn to the image resolution?
The quality of the photo will drop noticeably and the image may become blurry on certain pixels.
Do digital photos from disc lose quality each time you print?
A JPEG image loses quality when it is opened and resaved due the compression algorithms. The more an image is opened and resaved, the more the quality can degrade. An image on a disc will not lose quality unless you resave it on a CD-RW. Opening an image to print will not affect the quality.
Is decompression of an image introduce noise?
No, the decompression itself does not introduce any noise or loss of quality. In order to avoid loosing quality again, do not save the image in a format using lossy compression (like jpeg).
What exactly does JPEG stand for when you save a file image?
A JPEG is a format that an image file can be saved as. The acronym JPEG stands for Joint Photographic Experts Group. This was the development group for 24-bit colour image storage.
How can reduce a picture or image?
The question is the same with changing an image resolution or its format (reducing it to decrease the storage size of the image). The quick answer is "use an image converter or editor to re-compress your photographs". You will loose a minimum in quality (not noticeable in all cases but very special ones) and get a 3-5 times smaller image. Common software are MS Paint, GIMP, Photoshop, Irfanview, ... The long and more complete answer starts by stating that the size of the image is given by multiple factors: - image format (jpeg, png, bmp, ...). For an optimized size of photographs jpeg is probably the best alternative. Changing a photograph to jpeg will make a big difference and will have minimal impacts on the image quality since the jpeg format was tailored to efficiently store color images. - parameters of the image format (most important factor here is the compression ratio). Just by increasing the compression ratio, the size of the file decreases considerably. Using a computer to re-compress jpeg images is also a big leap in reducing the file size since the parameters of the jpeg library used in digital cameras trade size for memory usage and processing power. The computer has plenty of memory and processing power so that the jpeg library can compress better. - image resolution. If none of the factors above work well enough for you, reducing the image size is the most effective way in achieving a smaller file. Beware that the loss in quality is one the downsides of this method. It is the most suited solution if you want to pack some photos in an email and send them. Keep the originals in the case you want to do some printouts later. Once the resolution is decreased there is no way to get the old photo back to the original resolution without noticeable quality losses.
