In the Windows operating system, you can open PNG by simply double-clicking to view images. You can open a file with the PNG extension using virtually any viewer. You should know that unlike GIF, PNG does not support animation effects. The main difference between gifs is that such a graphic file is limited to only 8 bits (256 colors in total). PNG supports a color depth of up to 48 bits. Among the owners of web resources, PNG images are famous for their excellent characteristics against the background of such formats.

ICO was developed to replace the GIF format, because the latter required paid software for a long time. Thanks to the Deflate compression algorithm, bitmaps with the PNG file extension are available for compression without obvious quality loss. Such a graphic format is quite often used in the world wide web when assigning different images to web pages. The PNG data contains a specific palette of colors used in the drawing. The PNG file (Portable Network Graphic) refers to bitmap images. In addition, it should be noted that browser support for SVG has proven to be incomplete - currently a large number of browsers, including Internet Explorer, require an additional plugin (which many users will not have) to display the SVG image.

Specifically, SVG Tiny (SVGT) and SVG Basic (SVGB) are subsets of the full SVG standard primarily intended for use on a device with disabilities such as mobile phones or PDAs. There are several versions of the SVG format in use today (SVG 1.0, SVG 1.1, and SVG Tiny 1.2 at the time of this writing).

SVGZ format is a modified SVG format that uses GZIP compression and thus solves the problem of large SVG file sizes.

Support for manipulation and combinations of objects, including grouping, transformations and event-based scriptingīased on XML (which is essentially a text format), SVG images compress well.

Support for vector shapes (such as lines, curves, etc.).

The SVG format is used for both static and animated graphics. SVG is based on the XML markup language, and was developed as an open standard by the World Wide Wide Consortium.

For demo purposes, I’ll be using the Helium SVGs to convert to icon fonts, but you may wish to use any custom SVGs of your choosing.The SVG extension (Scalable Vector Graphics) is used primarily for vector graphics and is an open format.

However, these have their own configurations with React Native Vector Icons, and for this article, I wanted to focus on how to convert SVGs to icon fonts without these SaaS. There are other popular SaaS SVG and icon managers (both desktop and web) to choose from such as Fontello and Icomoon.

Nucleo Icon Manager (Free desktop app for Mac/Windows) - For this article, I chose to utilize Nucleo Icon Manager app.

Otherwise install react-native-vector-icons directly: )

React Native Vector Icons - If you’re using Expo (managed or bare workflow), you can utilize the Expo wrapper for react-native-vector-icons.

So let us get started: The tools you’ll need: If icon fonts fit your needs, fortunately for us react-native-vector-icons already provide an easy way to create custom icon sets. Unlike SVGs, where each path or element can be animated individually, icon fonts cannot be treated the same way because they are not vectors. An icon can only be styled one color at a time.

Icon fonts don’t support multiple colors.

Of course, icon fonts do have their limitations such as:

Are hosted in a single file locally or on a CDN and you can easily choose any icon to display using the corresponding class or code (or Glyphmap).Can be referenced directly from the same Icon component, making them accessible with all of those icon sets into the same package.Icon fonts are still a great choice for large-scale custom icon sets to scale over time. Most of the time SVGs are handled as an individual component. While this is a popular solution, this could be cumbersome to set up and difficult to maintain if the custom icon set grows in time. The most common route is to create these icons via SVGs. Generally, there are two routes developers take. While there are countless options for us pre-packaged, sometimes the options available don’t fit the design or a design system introduces a custom icon set just for the project. In React Native apps, we’re given a number of options when it comes to free and open-source icon sets to apply to our projects, such as FontAwesome, Google Material Community Icons, Ionicons, and more. Icons are a common UI element used to provide visual information and cues to users of what an element represents.
