Know The Various Image Formats For Websites

Monday May 18

Image is one of the mandatory instruments on the website. If your content is only filled with text, your web visitors might get bored, lazy to read, and immediately close the website. So, with the pictures and animations, the website will look more lively. With the right strategy, images can also support the SEO agenda.

But did you know that many image file format choices can be posted on the website? Placement of images with certain formats and sizes are dynamic, adjusting to how the images will be used online later. In this article, we will share insights about the types of image formats commonly posted for websites.


Joint Photographic Expert Groups (JPEG) are the most common image formats with 24-bit image formats. That is, the image is capable of displaying up to 16.8 million types of colors. You will also find a good photo or picture display because it includes more than 256 colors.

The data storage format in JPEG is lossy. So, when compressed, some image details will erode and the file size becomes smaller. Therefore, be careful when you want to compress images to be uploaded on the web. Do not let the low quality and appearance are broken.

2. PNG

PNG aka Portable Network Graphics is an image format that is devoted to websites with a file storage format that is lossless. That is, it cannot be compressed, and the image quality is fixed. PNG is divided into two formats namely PNG-8 and PNG-24. In PNG-8, the maximum color display capacity is 256 colors while in PNG-24 format, the color display can be millions with maximum image quality.

Because this type of image file can maintain image quality, you must be careful with its large size. You need to provide a large storage space when you want to upload images on the web so it looks good to see.

3. GIF

Graphics Interchange Format or GIF is an image format with limited quality because it only supports 256 colors. This does not mean that GIF images are not suitable for uploading on the web. Instead, it can save storage space when you want to upload logos, flags, or icons.

This type of file format is also good for simple forms of animation. In terms of data storage, GIF is similar to PNG which also holds the principle of lossless compression. That is, when you upload the file to the website, the file size remains intact.

4. SVG

Scalable Vector Graphics or abbreviated as SVG is a vector image format. Display images using polygons and computer graphics that contain attributes such as line thickness, fill color and lines, shapes, and curves. Unlike the JPEG, PNG, and GIF image formats, the SVG format closes the chance of the image display breaking when the image size is enlarged. This is due to the unlimited pixel size.

Writing SVG is created in XML-based markup. This is almost the same as HTML with responsive design. That is, it can be modified using JavaScript or CSS code. So, when you want to engineer an image or change the original image to taste, choose the SVG image format.
