With digital photography, images are stored as a digital file. RAW files are lossless. To reduce file size, the camera can discard part of the data not easily perceptible to the human eye. A JPEG is a lossy file. A TIFF file is, in principle, a flexible format that can be lossless or lossy.When you take a photograph, There are many different types of file formats, which can be retrieved and edited using a photo editing software. The most commonly used ones are,Choosing the right file format is important, and can be critical depending on the level of quality, and also the level of post-processing you intend to do. Here are the pros and cons of using each different image file format.

1:-JPEG(Joint Photographic Experts Group).
This is probably the best known of all image file formats, and what the majority of digital cameras provide as a digital output from a camera. The thing that you should remember is that JPEG files are compressed quickly in the camera, and thus result in a loss of detail and quality. They are essentially set up to store as many images on the memory card as possible. Some cameras will have options for different quality levels of JPEG (e.g., low, medium, and high). This basically means that the better the quality that you require, the less compression the camera will perform on the original photograph.
Generally speaking JPEGs should be used:
When the photos are for personal use, for social media, albums, and small prints and not intended for large size prints
When you don’t intend to enhance or edit the photos much in post-production (e.g., using Photoshop)
For sharing images via email (without the intention of large size prints)
-Small file sizes means more can be stored on a memory card
-Quicker file transfer times, due to smaller file size
-Loss of quality due to image compression
-Less opportunity for image manipulation in photo editing software
2:-TIFF (Tagged Image File Format).
This is the most commonly used industry-standard file format, and is generally what print or publishers ask for. Even if the end file format required is a JPEG, the initial captured file would be TIFF. These file formats are usually uncompressed, and as a result offer the opportunity for extensive post-processing. Due to the fact that they are uncompressed, they are also much bigger files, so will take much more space both on your memory cards and also for storage on your computer. Some cameras offer TIFF as the highest image quality level in camera.
-Ability to manipulate photos extensively in photo editing software
-Option to print at the highest quality and at much larger sizes
-Much bigger file sizes (more storage needed)
-Longer transfer and loading times due to file size
RAW files are generally available on advanced compact cameras and DSLRs and quite simply put; it is the best option if you want to get the absolute best file from your camera ,this is the option preferred by professional photographers. The problem with not using raw files is that your camera will make adjustments, which are permanently embedded into your photos.
Raw files are compressed using a process that retains all of the information originally captured. This means that adjustments such as white balance, exposure, contrast, saturation, sharpness can all be altered in an image editing software, after the image has been taken. Photographing in raw format will require plenty of memory cards, not to mention considerable post-processing time. It will also require some basic knowledge of image editing software such as Adobe Lightroom or Photoshop, as files will have to be edited and converted before they can be used (to share online, print, send to friends, etc.).
-The best quality image file is captured
-Extensive options in post-processing and image manipulation
-Time needed to convert and edit photos (you must edit raw files)
-Bigger file sizes mean more storage needed and longer post-processing times.
