There are many different image file types available on computers. Image file types indicate that images are encoded differently. You cannot open every image file in every program. The type names of these image files are different, as well as their icons on the computer, and they work in different programs.
In this article, we’ll tell you the difference between the ten image file types and when you can use them. After reading this, you will hopefully get an idea about which format you should be using for your professional needs.
Image File Types
In digital media, image files have measurement units. File sizes are directly proportional to the measurement degree and can therefore be either high or low resolution.First of all, the visuals are divided into two different types. The first is the raster image file; the second is the vector image file.
Raster Image Files
Raster image files are pixel-based images. When you enlarge such pictures, the quality of the picture deteriorates. When you reduce it, the quality increases.
GIMP, Photoshop, Paint have widely used raster image file editing applications.
Examples of raster image file types are BMP, JPG, GIF, TIF, RAW, PNG, PSD.
Vector Image Files
Vector image files are resolution-independent. They can be rescaled to any size. Vector image files have infinite resolution. There is no deterioration in quality when they are enlarged or reduced. It is also easier to edit.
Many usually use it for company logos, as well as pictures with text.
Adobe Illustrator, Corel Draw, and Inkspace are the most widely used vector drawing programs.
EPS, SVG, XAR, ART, VRML are examples of vector image file types.
Now, after learning about these two image types, let’s take a look at the image file types.
JPEG (Joint Photographic Experts Group)
First of all, JPEG is the type of image file we use most. Developed by the Joint Picture Experts Group. Most cameras shoot in JPEG. JPEGs are known for lossy compression, i.e., when the file size is reduced, the quality of the images also decreases. However, it has the ability to adjust the quality in the JPEG format. The quality is adjusted according to the degree of compression of the file. The less you compress the file, the higher its quality will be.
It contains true color values. For this reason, it is used for linear or non-graphical images.
They are generally used by web designers to transfer images to the web.
GIF (Graphics Interchange Format)
GIFs are animated images; they have animation support. Animations have timing and the ability to keep different files together. The file size is small due to the limited number of colors. It has color supports up to 8-256 bits. There is no true color support feature. It is an image file type with lossy compression. Often, another program is required to open an image in this format.
GIFs can be easily shared on the internet.
It is common in banner ads. It is well suited for solid color graphics and logos.
This file type is a lossless compressed file type. The file size is larger, which means higher quality. Also, their quality deteriorates when they are enlarged and reduced. It was developed by Microsoft. They do not work on the web. It contains a pixel depth of 1-24 bits.
Actually, JPEG and GIF are also a BMP file, but because they are lossy compression, these file types are smaller in size.
They are mostly used for printable image files.
PNG (Portable Network Graphics)
The PNG image file type features lossless compression. Its purpose is to bring the image quality that includes lossless color and transparency information to the internet. The quality does not decrease when editing PNG files, but they are still low resolution. File sizes are small.
There are two different types of PNGs:
PNG-8 is similar to the properties of GIF. It’s even smaller than GIF files. It is 256 colors and 1 bit transparent.
PNG-24 has a 24-bit color gamut. It can contain 16 million colors. You can compress it with lossless compression.
Usually used on websites. It is not suitable for printing.
TIFF (Tagged Image File Format)
TIFF was developed by Aldus Corporation for saving scanned images. Used for files such as graphics, photographs. It can be used on web pages without degrading its quality, but it takes too long to download a TIFF type file; it is a large scan file. This format features lossless compression (may contain lossy compressed images in JPEG format and lossless compressed images in PackBits format). Also, it is a flexible and adaptable image file format.
It has the ability to edit color values when used in any program. You can open them directly in Photoshop. Its use has gradually decreased because it takes up a lot of disk space and contains a buffer overflow. Many prefer it for images with high depth. Suitable for photo printing.
PSD ( Photoshop Document )
PSD is the recording extension for Adobe Photoshop files. Supports multiple alpha channels and layers. The biggest drawback is that Photoshop consists of vector images, while PSDs consist of raster images.
Ideal for editing image files. Supports all Photoshop features, binary files, indexed color, true color. It supports files up to 2 GB. One generally uses it for software and graphic design purposes.
PDF (Portable Document Format)
PDF is a universal file format for Adobe. People can open them on any hardware or operating system, and the templates look the same no matter where you open them. In other words, one can use without any extra application.
A PDF file contains texts, images, tables, postscripts. It has formatting and page layout features. If there is more than one page in the PDF file, the desired page can be easily navigated through the search box. There are different versions of the PDF image file type, and each differs in color support.
- PDF 1.2: It is the oldest PDF format. It is very insufficient for printing.
- PDF 1.3: Produced by Distiller 5 and Acrobat 4. It is not good enough for printing.
- PDF 1.4 .: Produced by Acrobat 5 and Distiller 5. It is the most suitable version for printing.
EPS (Encapsulated Postscript)
It is a type of image file type where graphics are saved in high resolution, and quality is preserved. It can be used in any graphic design program. You can edit them easily. They are in vector format.
It is a very useful image file type when designing large-scale graphics. One can enlarge it as much as desired, and its quality does not decrease. For this reason, you can use it in logo designs.
Supported in almost all drawing and page editing programs. It has the ability to edit the color values of the image and the background when opened with any program. You need to switch a color document to CMYK mode to avoid printing problems. You can save EPS image files in two different ways:
- DCS1: It is for EPS files saved in CMYK. It consists of four files containing high-resolution color information, and the fifth is the main file you will use to edit the page.
- DCS2: CMYK+ is for extra colors. Used to print the fifth or more color channels in the file.
The least processed type of image file. Numerical data are processed directly into memory without any process. Since they contain raw information, they take up more space than the JPEG image file type.
It is perfect for photography. The system saves the photo as a raw file when you take it, and when you transfer or edit your image to a device, it saves it using either the JPEG or TIFF image file extension.
One of the most beautiful features is that after shooting if you made a mistake on the photo you took, you can correct that mistake. Programs such as Picasa, Microsoft RAW Image Thumbnailer and Viewer, Adobe Photoshop, Adobe Lightroom, Capture One, PhotoScape can open the RAW image file type.
AI (Adobe Illustrator)
It was Adobe Illustrator that created this type of image. With this type, one can edit images very easily. It is a vector software. Therefore, when you enlarge and reduce the pictures, their quality does not decrease. It has the ability to transform shapes and colors into logos and symbols.
You can synchronize your image files as the AI image file type. If you save your image file as .ai, you can edit your file even if you use it in another program. You can open them by CorelDRAW Graphics Suite 2021, Adobe Illustrator CC, Adobe Photoshop, Adobe Acrobat, Adobe InDesign, Adobe Flash, Adobe Dreamweaver, and Gimp programs.
FAQ About Image File Types You Can Use
Raster is resolution-dependent. Quality decreases as the image size is enlarged or reduced. Vector does not depend on the resolution. You can enlarge or reduce the picture without degrading the image quality.
Yes, their resolution will deteriorate.
You can use Windows Paint or Photoshop software to change the image format.
For windows; Open the MS Paint application, go to the resize option, change resolution.
For Mac; Open the preview app, adjust the size, click the OK button.
To do this, click right on the picture, select properties. In the opposite of the file typewritten under the General tab, it will be written what type your image file is.
