IMAGE FORMATS


 Difference between Vector Image and Bitmap  

Bitmap or raster images are images with points that are distributed called pixels. These dots are 
perfect for images with many details, and thus define well their contrasts and colors by each of the 
pixels.


However, a vector graphic does not lose quality no matter how much you enlarge, and adapt to the

resolution of any output device. 


  AI image format                                                

The AI ​​format is from Adobe Illustrator, a vector graphics program .


 SVG image extension                                         


Currently we can use SVG in the browser itself, be it Chrome, Safari or Firefox, being an image file 
not very heavy, without losing quality, and we can even include animations in the image itself.

It should be noted that we can use the letters in a format that is capable of tracking and indexing by
Google, so it is one of the biggest advantages of this format to improve our SEO positioning.


 EPS image file format                                        

Normally when we download vectorized images from the internet, they come in EPS format, ready
to print, being able to open them in any compatible design program.


 PDF Format                                                       

PDF (Portable Document Format) is another version that any client can easely open with its PDF
reader program such as Adobe Acrobat. In addition, you can open it vectorized if you have 
saved this  way.

 JPG image format type                                      


JPG (Joint Photographic Experts Group) extension is the best known and most used format for 
saving images. This format loses quality due to its high compression, so it is perfect for when we do 
not need a very heavy and detailed image.

The majority of cameras and images that we find on the internet are stored in this format, being 
ideal due to their weight, since if we include them on our website they will weigh less than other 
extensions, improving the loading speed.

 PNG image format                                             


As I just told you, in PNG (Portable Network Graphicsyou can include the transparencies you need 

without losing quality, so you can use it in your logos, images without backgrounds, etc. 


Within the PNG formatwe find others based on the amount of information it stores: PNG 8 

and PNG 2.


Example: Here you can't see the squares that are behind the picture, but where I found it, you 

could see them.

 BMP image file format                                    


The BMP (Bitmap) format is a bitmap format developed by Windows.


Although this format has no loss of quality, since it stores a lot of information in a large size

and weight, it has lost relevance with the appearance of JPG or PNG.


 TIF or TIFF image extension                         


The TIF or TIFF (Tagged Image File Format) format is used for saving images in which

many colors and details appear, such as high-quality professional photographs.


It supports a storage of colors of up to 32 bits, so it has a large size due to the amount 

of information, being very heavy. It also has no loss of quality when compressed.


Supports files up to 4GB in size, making it ideal for photographs with many details.



 GIF format                                                      


We see it daily, especially in Social Networks. It is a format that supports animations

by reproducing images in a row and immediately upon opening, achieving an

incredible visual impact.


You can have up to 256 colors and compress the images, so the image format is

usually small, unless you have high animations.








 PSD Image File Type                                        


A PSD is created with Adobe Photoshop.


This has the option of creating vectors, but it is mostly used for bitmap images.


The main disadvantage of this extension is that if you do not have Adobe Photoshop installed

you will not be able to open the document.


 RAW image extension                                      


The RAW image format is typical of digital reflex cameras.


The majority of photographers use this extension, since it does not compress the photograph and 

will have the highest possible quality.


Once you have your picture on your computer, you can make all the changes you need with 

editing programs.
