Image File Formats and Image File Extensions List
Read on to know the differences among different image file formats used in photos.
JPG file format is one of the most popular file formats when you consider image retouching. Whether you deal with headshot retouching or general image retouching, photos are saved in this particular format.
A large number of websites also use JPG format in the images. Besides, photos captured in digital cameras are stored in this format. The key reason for the popularity of this format is that the size of files is not too large, and they can be stored easily.
It is also possible to make the date appear smaller so that the attention lies primarily in the image. Pages in websites load faster if the images are small in size.
Heavy images make the website slow. Due to the small storage size of these images, these are widely used in websites. Evidently, the JPG format is used when the minimum size of the image is required.
Another reason behind the extensive use of the JPG image format is that it can be compressed without causing any loss to the image quality. This property is immensely helpful in many cases.
Generally, when images are minimized in size, they suffer from a qualitative loss while uncompressed image formats have a high standard of quality. However, images in JPG format can be compressed as and when required. This will not deteriorate the quality of the image. This is a most popular & commonly used format.
Pros of JPG Format
- High Compatibility
- Quick Load Time
- Full Color Spectrum
Cons of JPG Format:
- Doesn’t Support Animation or Transparencies
- Lossy Compression, etc.
TIFF is another widely used photo format and has the ability to retain its quality even when the file size is minimized. In fact, it caters to the requirements of various commercial segments.
However, a major drawback of TIFF format is that it cannot be used on websites. It is for this reason websites have images in JPG format. Comparing the two, TIFF has a broader ground of utility. The only limitation of the format is its incompatibility with websites.
The quality of the image remains intact when it is compressed. This format is extensively used in the fashion industry and portrait retouching. This format provides all the features required by a photographer.
Pros of TIFF Format:
- High image quality
- Layers & transparencies
- Lossless compression
- Ideal for printouts (Photographs), etc.
Cons of TIFF Format:
- Compatibility issues with many browsers
- More storage space required
- Not appropriate for websites (Increases Load Time), etc.
GIF is one of the oldest photo formats. It was designed much before JPG and TIFF. This format came into inception at a time when 8-bit videos became popular and served the video purposes much effectively. GIF was unique in a number of ways.
However, this format has its own limitations too. It is not suitable for printing which is the main drawback. The number of colors that can be used in GIF format is limited to 256. Although all variants of colors cannot be incorporated in this photo format, it is sufficient for a graphic purpose.
It is for this limitation that photo editors avoid using indexed colors to enhance images in GIF format; also, for photo color correction services, this format suits the least. Unlike other formats, modern GIF files offer more transparency and animation.
Today, this format is widely used in web graphics, where people do not look out for the variety of colors. GIF is also known for its pure color shades and smaller sizes of files.
Pros of GIF Format:
- Professional animated image output
- Small file size
Cons of GIF Format:
- Limited color palette
- Once Created- Cannot be edited, etc.
This file format has been the latest inclusion in the list. It has most of the attributes of TIFF and is a very useful format. A key advantage of PNG over TIFF is that it can be used in websites and most web developers are really comfortable using it.
The purpose of designing this format was to bypass the inconveniences owing to the loss of quality of other photo formats. GIF format is likely to be replaced by PNG. Both these formats are supported by browsers, but PNG provides more benefits than GIF.
As the format has been designed lately, it is powered with the latest features. PNG files occupy lesser space when images are converted from other formats. However, a disadvantage of PNG files is that websites are slow in reading images in this format.
This is the reason why it is not as popular as JPG and TIFF. However, it is widely being used by contemporary photographers. The format does not lose its quality during photo retouching and hence ideal for photo manipulation.
Pros of PNG Format:
- Lossless compression
- No data is lost
- Ideal for graphs & logos with different figures, etc.
Cons of PNG Format:
- Compresses digital images at large size
- Not ideal for printing graphics of professional quality, etc.
This is a layered image file format, which is the default format when using Adobe Photoshop to save images. Photoshop Document, abbreviated as PSD supports multiple layers of image and numerous imaging options.
This is very helpful in case, the editor has to resume the work for a later time and also if one wants to make changes in a particular layer without disturbing other layers.
It saves an image all-inclusive of its clipping paths, shapes, layer masks, adjustment layers, styles and even blending modes and helps to preserve its transparency.
Also, know the reason why most of the photo retouching agency provides final output in PSD format.
But they are only read or opened with Photoshop or other Adobe products and selected graphics applications and also the image cannot be displayed on the web if saved in this file format.
As there are many layers, the PSDs will be of larger sizes and hence require a high storage space provision while dealing with a huge volume of PSD files. Also for these images to get printed, they need to be saved in an appropriate file format after all the editing and manipulations. This is but, the highest quality image format for Photoshop edited images, which is commonly created and shared among graphics professionals.
Pros of PSD Format:
- Ideal for website layout design
- Basic animation can be created
- Ideal for batch editing
- Supports raster & vector graphics
- Other format conversion possible, etc.
Cons of PSD Format:
- Extensive layer editing
- Requires more storage space
- Photoshop required prior to the use, etc.

RAW Image Format
A RAW image is a file that has been processed to a negligible extent. In fact, it is the preliminary format that an image takes over at the time of its creation. When you use your camera to click a photo, the photo gets saved in the RAW format.
Your image would get a new file format when you get it uploaded to a new device and refine it by using a photo editing program. You will find RAW images to be very detailed because they capture all elements and finer visual details that remain unprocessed.
This format would eventually get converted into a vector or raster format that can now be shared through other devices or resized for diverse purposes. Notably, there are several RAW image file formats that you can use to save your images. In fact, some formats are native to some camera models.
Here are the four main types of RAW files that we commonly come across:
- CR2: CR2 or Canon RAW 2 is a Canon-specific file format that is commonly found in photos that ate clicked through Canon’s digital cameras. These are images of superior quality as they are primarily based on the TIFF format.
- CRW: The CRW file extension was introduced by Canon before it introduced the CR2 extension in the market.
- NEF: The Nikon Electric Format image extension is a type of RAW file that was introduced by Nikon. Images of these formats can be edited extensively without having to change the file-type only if you use a Nikon Photoshop plug-in or a Nikon device to edit the files.
- PEF: The Pentax Electronic Format is a RAW image format that is native to Pentax Digital Cameras.
Pros of RAW Image Format:
- Brighter image output with better quality
- Flexible editing options, etc.
Cons of RAW Image Format:
- RAW shooting slows down the camera speed
- Not standardized across various camera
- Issues in sharing files
- More storage space required, etc.
SVG or Scalable Vector Graphics is an image format for vector images and is based on XML. This format typically represents 2D graphics. You can easily search index, scale, and shrink images in this format so as to create small-sized images that can be readily used in online platforms.
Files in this format can be refined using graphic design programs and text editors alike. You should use this format if you have to create computer-generated imagery for online use. This image format is not suitable for use in print outcomes.
Pros of SVG Format:
- Scalable & flexible
- Images are small in size
- Easily compressible, etc.
- Used for various web animations
Cons of SVG Format:

This is a modern image format that facilitates efficient lossy as well as lossless image compression online. The use of WebP allows web developers to create high-quality yet small-sized images, which in turn boosts website speed. The lossless and lossy images produced in this format are smaller in size than the PNG and JPEG images. Lossless images in this format take just an additional 22 percent bytes in order to support transparency. WebP is supported by numerous software libraries as well as by Google, Opera, Edge, and Firefox. The lossy compression is performed through the use of predictive coding whereas the lossless compression process makes use of existing image remains to build new pixels. It comes with tools to view, mix, and animate WebP images.
Pros of WebP Format:
- Smooth color gradations
- Improves compression algorithm
- Alpha channel mask
- Faster web page load time, etc.
Cons of WebP Format:
- Poor exporting process & interface
- Not compatible with all browsers, etc.
Lossy vs Lossless Image Formats
The problem with most of the amateurs or beginners who are very new to the professional world of Image creation is that they start editing without knowing the features of each of these formats.
Even if they study a few formats and go through various photo editing tips for them online, the knowledge remains insufficient to support them in their career.
However, professional photographers and image retouching experts determine the formats to be used after assessing their needs.
When you work with images, you may need to address several complex requirements at times. Image editing is not an easy task, but continuous learning and practice would make things perfect.
