Most common file types and uses:

PSD:

Stands for Photoshop Document. This file type gives you lot the near access without quality being lost and allows for files to be saved at a larger size. Information technology saves all layers, channels, text or any other settings y'all have been working on. This is most commonly saved as your original file which whatever final edits should be made to. For example, work on your PSD file for making last edits, so save a copy with no editing capabilities (no layers) for printing.

TIFF/TIF:

Stands for Tagged Image File Format. TIFFs are similar to a PSD file in that they allow full editing capabilities. Images are also saved at the highest quality without quality being lost over fourth dimension. This is the preferred file blazon when sending images to print. It is recommended to piece of work on your original PSD file and save a flattened (no layers) TIFF file when printing. This allows quality to be maintained, but file sizes may not be equally large every bit a PSD.

JPEG/JPG:

Stands for Joint Photographic Expert Group. This file blazon does not save layers and is considered a flattened file. JPEGs are the most unremarkably used files for the web and for sharing photos with friends and family unit. Almost frequently, digital cameras salvage epitome files as a JPEG/JPG. They are able to be saved in a much smaller file size, which frees up space and makes information technology more convenient, but every bit a result are considered a lossy file. In other words, they do not maintain quality and lose quality over time. Every fourth dimension you open a JPEG file, quality is lost. For comparison, consider copying an image on a copy machine, so making a copy of that copy and doing the same thing repeatedly. Yous will notice the image slowly lose quality with each re-create made. The same concept applies to a JPEG. So, just call back, effort not to open JPEG files and so no more than quality is lost. It is ever best to have an original file such as TIFF or PSD you lot can go back to for maintained quality. Tip: JPEGs are your friend for the web and files sharing, simply not maintaining quality.

GIF:

Accessible through the 'Save for Spider web' menu, the GIF stands for Graphics Interchange Format. The GIF is an even lower quality file blazon in comparison to a JPEG and is used for the web. It reduces the amount of colors in the document to reduce the file size as well. However, considering information technology is lower in file size and quality, it promotes fast download time for web pages. It also is attainable for all Cyberspace browsers. Two major advantages of the GIF is that it supports transparency and you tin can apply simple animation with layers of images using the Animation tool.

PNG:

Stands for Portable Network Graphics. This file type is less known and used and was originally intended to supervene upon GIF files because it supports transparency but like a GIF, maintains quality and contains more colors. Although it is not quite every bit popular, it is a better file type than both the GIF and the JPEG for digital images. This is because it maintains the quality of an epitome, regardless of how many times it is opened. The merely downsides are that it does non support CMYK color style, meaning information technology cannot be used for printing, does not support animation and because it is not as known or used equally much, some Internet browsers may not back up it. Tip: When choosing to save digital images, cull a PNG over a JPEG to maintain quality. PNG files are also practiced to use for Wink and PowerPoint Presentations.

PDF:

Stands for Portable Document Format. Virtually used for file sharing, viewing and press. Images can be saved as a PDF file in Photoshop, which allows for maintained file features, for example, layers. Yous tin save information technology every bit a JPEG compression or a ZIP file to forbid loss of quality. Ane advantage of a PDF image file is being able to use spot colors. Spot colors are specific colors used in the press industry. For example, if you are going to print a file as a one color epitome, you would utilize a spot color. Past far the greatest advantage of saving in a PDF format is accessibility. Anyone will be able to open the file on any reckoner every bit long as they have Adobe Reader installed. Adobe Reader is a free software by Adobe that is or tin exist installed on the majority of people's computers. Nigh people already have or can install this software within minutes.
