1- whats is an image format?
Images are an important part of any document and come in a variety of formats. These formats include JPEGs, TIFFs, GIFs, and PNGs. Each of these file types is useful for different purposes and can add a unique touch to any document. JPEGs are the most common image format and are best used for photographs or complex images that need to be printed or viewed on digital devices.
Images are a popular, yet important, form of communication. An image format is a specific file format that stores digital images. There are many different image file formats, including the most commonly used formats like JPEG, PNG, GIF, and BMP. Each of these formats has advantages and disadvantages when it comes to image quality, file size, and compatibility with different software.
2- The difference between JPG, GIF, PNG
1- JPG format
The JPG file format, which stands for Joint Photographic Experts Group, is a type of image compression that works best for photographs and complex images.
JPG files use a compression method that removes colors invisible to humans from images to reduce file sizes. however. If you reduce the JPG quality too much, you will start to lose important color information that cannot be recovered.
The JPG file format also allows you to save progressive JPG files, which will be uploaded in stages. You may have experienced this when visiting a website and watching as an image slowly blurred and became clearer.
Despite the common use of this format, JPG is a format that does not support transparency, so don't use it if you need to see through the image and decode the background through it.
2- GIF format
The GIF extension, or Graphics Interchange Format, reduces the number of colors in an image to 256, out of the thousands of possible colors coming from a digital camera. GIFs also support transparency.
GIF files have the unique ability to display a series of images, similar to video clips, called GIFs, which are a series of separate GIFs that are strung together to automatically create a movement or animation.
GIF files, like JPG, also have the ability to load in parts on web pages. These images, known as nested GIFs, tend to be a bit larger than regular GIFs but allow the GIF to be partially visible while it's loading on a web page.
GIFs can be used effectively for images with limited colors, such as logos and graphs, or for images where transparency is important.
3- PNG format
PNGs, or Portable Network Graphics, were created as an alternative to the GIF file format when GIF technology is copyrighted and requires permission to use.
PNGs allow 5-25% more compression than GIF files, with a wider range of colors. Like GIF files, PNG file formats support transparency, but PNG supports variable transparency, where users can control the degree of transparency of the image. The downside to advanced transparency in PNG is that not all older browsers will display the same transparency.
PNGs also support image interlacing, similar to GIFs, but PNGs use two-dimensional interlacing, which makes them load up to twice as fast as GIFs.
3- how I use image formats correctly
With the advent of digital media, the ability to use different image formats has become a vital part of the creative process. I use JPG, GIF, and PNG image formats to create visually appealing digital artwork that is both aesthetically pleasing and functionally efficient. Knowing when to choose one format over the other is a key decision that must be made in the creative process. JPGs, for instance, are ideal for photographs and artwork with a lot of detail, while GIFs are better suited for simple animations that require less detail and fewer colors.
There are several criteria to consider if you want to create visual content for images.
First, don't use the GIF format if the image uses a wide range of colors. PNG or JPG files are best for wide-color gamut images.
JPG files are best suited for photographs or images containing photographic elements.
PNG files are best suited for images that contain detailed text, charts, screenshots, and illustrations.
When deciding which file type to use, for an image that does not contain photographic elements, it's a good idea to consider transparency and complexity. For an image that has a lot of colors or requires advanced variable transparency, PNG is the best format.
If the image contains few colors and does not require any advanced alpha transparent effect, then GIF is the correct extension. Keep in mind that any use of transparency or variable transparency should be tested in multiple browsers to ensure the effect is the same.
And in the end, images are considered an important and integral part of electronic content, and online merchants use them to promote their products and spread the general idea, whether it is a logo, background, or using it as link, or other endless uses of images! If you are familiar with visual content, you will know that image formats are different in the electronic world, and each format has different usage.
