When we talk about image formats, there can be numerous options like RAW, PNG, DNG, JPEG, TIFF, and so on. Out of them, some image formats like JPEG and RAW are more popular than others due to their wide usage. Though, in some cases, using specific formats like DNG or JPEG is just more practical. Therefore, in this post, I will provide a detailed RAW vs. JPEG vs. DNG difference and would let you know some of the best circumstances for using these formats.
Part 1: RAW vs. JPEG vs. DNG: Know the Basics
To start our RAW vs. JPEG vs. DNG comparison, let's quickly get to know the basics of each image format.
As the name suggests, RAW formats are used to depict unprocessed image files (that are shot on cameras). Since these files are not processed yet, they are not ready to be printed or uploaded. Though, you can still view them on your system and make the needed edits.
RAW images are often considered more dynamic and have a wider color range compared to processed files.
There are tons of RAW file extensions as the exact extension would be mapped by your camera manufacturer. Some of these common RAW image extensions are RWZ, RW2, CRW, NEF, ARI, CAP, DRF, ERF, OBM, SR2, and X3F.
RAW formats can also store details about your camera and its settings.
Since they are unprocessed files, they contain the true parameters of the image.
It is pretty easy to preview and edit RAW files compared to processed pictures.
The exact RAW format for your images would vary from one manufacturer to another.
Parameters in RAW files can’t easily be modified by third-party software.
They need specific software (mostly from the specific camera manufacturer) to be modified.
Note: RAW is simply a file type which may also encouter various problems, if you want to get reasons to shoot in RAW and factors influencing you not want to shoot in RAW, the article - What Is A RAW Photo? How to Recover RAW Photos from Camera can help you.
JPEG is the most popular image format of the present time that stands for Joint Photographic Experts Group. The container format was introduced in 1992 and consists of several file extensions such as JPEG, JPG, JPE, JIF, JFI, and JFIF.
Though, unlike RAW, JPEG formats follow a lossy compression technique, which means the original quality of your image would be lost. While the compression ratio can be as high as 10:1, it would also drastically reduce the size of your image.
It is a universal format to store and transfer images.
Almost all the leading image viewers, editors, and tools support JPEG formats.
The JPEG format can substantially reduce the overall size of your picture.
As of now, JPEG does not support layered images.
The original quality of your photos is suffered drastically.
Note: When you change the format of an image to JPEG and open in a default OS viewer, the colours may look too dim, an article - Fix JPEG Colour Change Export in Photoshop CC can be recommended.
DNG, which stands for Digital Negative, is a proprietary image format that is developed by Adobe. While it mostly follows lossless compression, there is a lossy variant of DNG that can also be implemented.
The format was initially released in 2004 and is supported by almost every Adobe image editing tool (like Photoshop or Lightroom). Some camera manufacturers (like Leica, Hasselblad, and Pentax) also support the DNG format to maintain the original quality of their images.
RAW files can easily be converted into DNG and can later be processed with several other tools.
We can make changes in any DNG image without modifying its XMP file.
DNG includes a unique checksum mechanism to easily detect if the file has been corrupted.
Even though DNG is used by Adobe, there are far fewer applications that support the image format.
It is first needed to convert RAW files into DNG to process them (that can take a lot of time).
While converting RAW files into a DNG format, some of its vital meta components might be lost.
Note: Fix corrupted DNG images in effective ways is a popular blog regarding corrupted DNG files, which also connected with the reasons behind the issue, and useful techniques to fix it.

Part 2: How to Choose the Best Format from RAW, JPEG, and DNG?
As you can see, all three image formats are quite unique and have different applications. Therefore, to draw a RAW vs. JPEG vs. DNG comparison, it is important to note their overall usage.
1. For Photography Experts
While some cameras have a feature to click photos in the JPEG format, it is mostly not recommended. If you are an expert, then consider clicking your photographs in RAW format. This would help you retain the original quality of the image, and you can easily edit or convert it in different formats afterward.
2. For Image Processing and Editing
There has been a lot of confusion between different image formats (RAW vs. JPEG vs. DNG) for image processing. Ideally, it is pretty subjective, and you can pick an ideal format that suits your needs. Though in most cases, DNG is a preferred format due to its support with Adobe Photoshop and Lightroom. If you want, you can convert a RAW image to any other format for editing.
3. For Screening
Besides that, if you want to screen your photos, then DNG would be a better option. This is because RAW files might not be directly supported by screening applications while JPEG can end up compromising its quality in the formatting process.
4. For Storage and Transfer
In most cases, JPEG is considered as an ideal format to store or transfer multiple photos. As I have listed in my RAW vs. JPEG vs. DNG comparison that JPEG has an excellent compression ratio of 10:1. This means you can store even bulky images in JPEG formats without occupying too much space.
5. For Uploading on Websites/Apps
Lastly, if you are uploading your images or would like to share them, then again JPEG would be an ideal pick. Since JPEG pictures and pretty lightweight and are universally supported, you can access them on any platform easily.
Tip: What to do if your RAW, JPEG, or DNG Pictures are Corrupted?

Which is the best-quality image format?In most cases, RAW formats (like TIFF, CRW, and NEF) are considered to have the best quality as they retain the original parameters of the image.
Which is the best image file format?The best image format would depend on your requirements. While RAW is preferred for shooting, DNG can be used for editing, and JPEG can help you store tons of photos in less storage.
Is PNG format better than JPG?This would depend on how you would like to use the image. Though the compression technique of PNG is much better than JPG. PNG can retain the original quality of the image and is easier for editing, but JPG is a more universally acceptable format.
Which is better, JPEG or BMP?JPEG would be a better pick to store your images and compress them via its lossy technique. Though, if you want to work on uncompressed bitmap images, then BMP would be a better option.
