JPG: can be shared anywhere without editing, RAW requires editing before it can be shared.JPG: universal file format, RAW is unique to each camera.JPG: small file sizes, approximately a quarter the size of a RAW file.First though, a quick summary of the differences between RAW and JPG, which also applied to RAW vs other compressed image types like PNG or HEIF. However, RAW does have a number of advantages, which we will cover in this post. So far, this doesn’t sound great for RAW files! They also take up more space, and aren’t of a universal file format. You can’t just grab these RAW file and upload them to the internet or share them with friends. So instead of “Image.JPG”, you would have “Image.CR2”, or “Image.NEF”. For example, Canon RAW files have the “CR2” file type.

Compare this to a JPG file of reasonable quality, from the same camera this will usually be around 4 megabytes – five times smaller!Īs I mentioned at the start of this section, every camera manufacturer has their own RAW file format. A RAW image file roughly works out to be around the same size as the number of megapixels of the camera – so for example, a 20 megapixel camera will save a RAW file of around 20 megabytes. This takes up a lot more space on your memory card. Essentially the camera takes the image data from the sensor, and saves it in an unedited and uncompressed format on the memory card. These changes are difficult to undo if you don’t like them.Ī RAW file on the other hand, is an uncompressed version of the image file. Additionally, the camera applies a number of tweaks to the image when it saves it in a compressed format, including adjusting the saturation, contrast, and sharpness of the image. A compressed image is a lot less flexible when it comes to editing, as much of the useful image data that image editors work with has been discarded in order to save file size. There are downsides however to using a compressed file like JPG or HEIF. They mean that when we load a webpage, we don’t have to wait ages for all the images to load, and when we email images to friends, we don’t take up too much of their inbox space. JPG is by far the most widely used, with HEIF being the default on most iPhones.Ĭompressed files are a good thing. They each have advantages and disadvantages. There are other types of compression available, such as PNG files, HEIF files and so on. The greater the compression, the greater the loss in quality, but the smaller the file size and the less storage space needed to save it. This means that various optimizations are applied to the image file, which makes the file size smaller.

It’s also how we publish photos on our sites. So it’s easy to take a JPG image file and share it to a social media platform like Facebook or e-mail it to a friend, and they’ll be able to see that image without you needing to edit or change it in any way. JPG is a universally agreed upon image format that can be viewed across pretty much every device out there. There is no difference between a JPG and a JPEG, they are the same. So a JPG file on your hard drive would look like “Image.JPG”. This is often shortened to JPG, as a throwback to a time when file extensions could only be three letters. JPEG simply stands for “Joint Photographic Experts Group”, which is the name of the group that created the format. The standard on most cameras and devices is a format known as JPEG.

Normally when you shoot with a digital camera or smartphone, the default setting is for it to save the images you take to your camera’s memory card in a compressed format. When using a camera, the two main photo formats available are JPG (or JPEG) and RAW.

When it comes to smartphones, most Android smartphones which support RAW primarily shoot in DNG, which is a universal RAW file format. It is minimally processed and is usually uncompressed.Įvery camera manufacturer has their own RAW file format, for example Canon RAW files are.
