psd A .psd extension file is an image file created with the help of Adobe Photoshop. PSD is the default extension used for saving a Photoshop Image which can have either a single or multiple layers which can be worked individually even after having saved the file. The file can also be saved in other formats like .jpg, .tiff, .gif or other imaging formats but if a user wants to edit the individual layers later, it is necessary to save the .psd file without overwriting it while converting it to another format. Converting a .psd extension file into an image file in another format flattens the image so that it can be viewed as a regular image. The images created using this extension are of a very high resolution and the quality in terms of clarity is extremely good as compared to other commonly used image formats like .jpg, .png or .bmp.
jpeg JPEG is abbreviated as the Joint Photographics Experts Group. It is a file extension that uses irreversible compression technology which helps in reducing the data size for storing data easier and advocates the seamless handling and transmission of content. A JPEG most commonly aids in storing digital images via "lossy compression" and includes images rendered by means of digital photography. Lossy compression does not let users restore the image file to its original quality after compression, once sized down. Some loss of the data stored in the image file occurs during the compression process. In simpler terms, when an image gets compressed, there's a reduction in its quality, thereby losing some of the graphical/visual data information; data reduction generates lower file sizes.
