Ep 5 Bro, I'm confused with JPEG, PNG, TIFF-

Updated: Dec 7, 2022

Here's a quick insight on JPEG or .jpg that you've probably encountered while saving your works, or pictures of your hang out last Friday.

The different file formats we will discuss in the next few posts are:

  • JPEG

  • PNG

  • RAW/CR2/NEF/ORF etc.

Don't worry the explanations will just be a bite size amount for you to absorb and not lose any brain cells. You'll be surprise that even your boss* do not know some of these information.

*Wolfpac boss is very well-equipped


Also known as Joint Photography Experts Group, which is an international organisation that standardised photos formats since the 1980s, and since then, photographers has been using JPEG for their photos. JPEG can also be saved as;

  1. .jpg

  2. .jpeg

  3. .jpe

  4. .jif

  5. .jfif

  6. .jfi

More information about JPEG:

  • Supports up to 24-bit colours

Bit refers to the amount of colours it can store in an image. The higher the bit, the more colours it can store in an image.

24-bit : 2^24 = 16,777,216 colors

A 1-bit image thus, can only store either black or white. As the number increases, the bigger the file gets as more colours is being stored in each pixel of the image.

  • Lossy Compression

Lossy compression means that the image file is reduced as some of the information data in the file is being erased. This process is irreversible and usually, images that are in JPEG format has lossy compression. Although this is good in terms of file size, but a tint of quality will also be reduced.

What is JPEG used for?

Common amongst photographers, the shots that they took will be in RAW (next post!) before they edit and save it as JPEG. This is because the photos are smaller in size, so it is faster to open it in other platforms like mobile phones without compromising the quality of the photos.

As what mentioned above about fast processing, JPEG file photos are also used for websites. It would be easier for the audience to toggle through the website without waiting for a long waiting time. The same goes for E-mail, not having to wait for a big file to load before sending the email and then require the other end to download a big file into their desktop - that's just tedious.

A quick explanation on what's bit

Bit or Bitmap is a grid of individual pixels that when come together, it will become an image.

Still don't get what we meant by this?

Open your photos on photoshop or illustrator and zoom all the way in, you'll see square grids with differing colours then when you zoom out, it completes your picture.

Okay phew, that was enough of talking. Here's some examples for Wolfpac Productions, we use JPEG for most(or all) of our photos!

Photos are from PUMA X HARRIS X ZAHRA, The Halal Corner, and AFF Suzuki Cup 2020

Well, that about it. If you have any question, don't be shy and drop us a DM on @Wolfpacpro on Instagram.

Till we meet again!
