3. GIFs
GIF is an acronym for Graphics Interchange Format. It finds wide use when it comes to animations. They are formed from limited colours. So they do not occupy large space. Their advantage is obvious, the small file size and its use for animated images. It also points to its disadvantage when it comes to image quality. It is limited due to the available 8 bit.
4. PSD
PSDs are files created using the popular Adobe Photoshop. It is virtually the most popular editing software when it comes to the world of graphics. They are created in layers, which makes editing pretty easy.
The major advantage of PSDs is the ability to edit individual layers, but the large-sized file generated remains a challenge.
5. PDF
PDF an acronym for portable document format. If you are not familiar with this acronym, you are not looking at creating an E-book. We mostly remember PDF when it comes to reading and saving text-based documents.
They are vector images and find high use in saving images like magazine covers and other images for printing in the future.
Their advantage is in its use for infographics owning to its searchable text. They were to preserve and protect content, making it hard to extract information from them.
You have given us a lot of very useful information on file formats. I found Harry's input below interesting. I had not heard of GIMP. I have been using a sort of Photoshop wannabe program called Photostudio that I received free with a scanner I bought many years ago. I don't think it is supported anymore. It says it only runs on Windows NT. But I can get it to run I just have to remember to keep saving my work otherwise it hangs itself. It has many of the features of Photoshop including working with layers, transparency, cloning, 2D transformations, and special arty effects but doesn't have the clever learning and macros that you get with Photoshop. I did have my own version of Photoshop many years ago when I was working in that field but I can't justify the cost of the license now and Photostudio does the trick.
I think the important questions for most of us are what are the best file formats to use for image creation and development, and then what formats are best used for online display on our sites. I wasn't aware, for example, that you can post vector graphics to websites, I guess other than PDF, but when I post PDFs I put them on separate single infographic pages with the express intent that they are available for download. I haven't tried embedding PDFs in a post.
Interesting topic.
Best regards

I stay more with JPEG, PNG and PDF. I WEBP would have been another alternative but its drawback of non-compatibility with all OS makes me drift away from it.
GIMP is free, you can easily download it from the net. I dwelt on GIMP and some free tools in this training 5 Free Image Editing tools that you can Use Thank you,

I will also continue with JPEG and PNG. I think the main point for consideration that I got from your article was that I could also use PDF for infographics. I tend to produce my infographics in Powerpoint and then export one version in PNG for display in the post linking to a downloadable PDF which I publish on a separate page.

You mention PSD using Adobe Photoshop and creating images using layers. To do this you need to use transparencies by removing unwanted background from different images and layering them one over the other.
This is ok if you can afford Photoshop, but what if you can’t. GIMP (Graphic Image Manipulation Program) is the answer. It’s free and, apart from some minor attributes, has everything you’ll find in Photoshop, more thanl enough unless you are a professional graphic designer.
This is where image file formats are important when creating images using transparencies and layers. Any transparencies created using JPEG will be lost when the final image is saved in the JPEG file format, as it doesn’t support transparencies. To overcome this problem, save the final image in the PNG file format.
Once the final image has been saved, upload it to Tinypng, where it can compress the image by as much as 70% without any noticeable loss.
Transparencies can be created using Gimp, but in many cases I find it easier to use removebg, an online background removal program. Below is an image I created for one of my sites using Gimp and seven different images.
Hi Harry, Just seeing this. I quite agree with you, GIMP is an excellent alternative to Photoshop. It is a totally free tool and it is easier to learn.
