What Is an SVG File?

SVG or Scalable Vector Graphics, which is an XML text-based vector image format. Usually, the images you see or download on the Internet have both JPG and PNG formats. Both formats are made up of small “boxes” called pixels. Meanwhile, SVG-formatted images rely on XML markup used to draw shapes, lines, and other image attributes. Keep in mind that SVG has been around since the 90s. However, the SVG file was only known a few years earlier. Then why should you use SVG? One of the privileges of SVG is that several platforms support this image format. You can see for yourself what popular browsers include Google Chrome, Safari, Firefox, and Chrome for Android that already uses SVG.

If you find this article, you must be wondering What is an SVG File? Then how do I open this file? Does it include image formats such as PNG or JPG?

When you search the Internet for images, you’re bound to come across images with the “.svg” extension. The file has been used for a long time, but it is not as popular as PNG and JPG.

What Exactly is an SVG File?

SVG (Scalable Vector Graphics) is an image format consisting of XML code and basic vector shapes. This format is included in the old school image format, considering that it has been around since the 90s.

Many people think this format is different from other images because it is less familiar. In fact, with this format, you will get many advantages over PNG, JPG, WEBP, and GIF.

Difference between SVG and PNG/JPG

The most fundamental difference is the way the primary color and shape are formed.

PNG and JPG use pixels or color dots (raster graphics), and each color code and its location is stored in a file.

JPG or PNG images, when enlarged to the visible maximum, are checkered. That’s their weakness. In terms of file size, the size of JPG & PNG is much larger than SVG.

SVG is the opposite of PNG and JPG. SVG uses vector graphics with XML markup code. Because it is made of vectors, the image model is created mathematically so that the lines or colors can be arranged together on your screen.

advantages of svg file format

Advantages of SVG File Format over PNG/JPG

The first advantage of the SVG format is that even if it is enlarged to 500%, the resolution will not break. This is because the broken image only applies to pixelated images. Unlike PNG/JPG, if you increase or decrease the resolution, it is easy to break or blur.

The SVG file size is also smaller because it uses the XML markup language. Many websites use this format because of its small size, which affects website speed.

Although not as popular as PNG / JPG, almost all popular browsers already support the SVG format. Therefore, it is not surprising that many websites use it as an asset.

Another advantage of SVG over JPEG, PNG, or GIF images is its scalability. So the resolution can be increased without losing quality.

The image quality will be maintained and look sharp when opened from different devices.

SVG can adjust automatically to the screen resolution on each device (Responsive).

Designers no longer need to design logos and icons of different sizes to suit other platforms.

How to Open SVG Format File?

With the help of a web browser, opening or viewing files in SVG format is very simple. This is not without reason because almost all browsers already support this format.

The trick is simply to click the right mouse button on the .svg file extension, then select the “Open with” menu, and finally select a browser to open it (Chrome, Firefox, Opera, Safari, etc.). After a few moments, the image will open in a “New Tab” window in your browser.

However, if you find it difficult to use a browser, you can use an online converter to convert SVG to PNG/JPG format.

tips for safely using svg images

Tips for Safely Using SVG Images

It is not a big problem for the security of a website if only the owner himself creates and uploads the SVG file.

The risk is if we take the SVG file from another source whose origin is not clear, then we upload it to the website without checking the source code first.

Because we don’t know whether it’s been inserted by malicious JavaScript code?

For that, there is a tool called SVG Sanitizer.

Its function is to check the XML source code in the SVG file and clean it automatically if there is “dangerous” code in it.
