7 Reasons To Pick WebRTC for Video Calling

WebRTC for Video Calling

WebRTC, also known as Web Real-Time Communication, is an open-source project and requirement that facilitates real-time media communications between browsers and devices. Today, WebRTC video calling has become a popular thing in the Internet world. Different types of real-time media communication that it supports include voice, video, and data transfer. With the help of WebRTC, users can easily communicate from within their primary web browser without using any complex hardware or plug-ins. 

History About WebRTC

Google initially introduced the WebRTC project in May 2011. It was announced to build a simple set of protocols for empowering superior RTC applications within browsers, mobile platforms, and IoT devices. When WebRTC was introduced, the only methods used for carrying out real-time communication were Flash and plugins. After a few years, the first cross-browser video call was established between Chrome and Firefox. After that, WebRTC gained a lot of popularity in the developer community. It is now one of the most popular and widely used tools for video calling purposes. WebRTC is available as a pre-built source in Chrome, Safari, Firefox, Edge, iOS, and Android. 

Reasons to choose WebRTC

Nowadays, more and more businesses are choosing WebRTC for video calling. If you wonder why WebRTC is so popular and why to choose this tool over others, here are some of the key reasons. Have a look:

  • Complete integration: WebRTC can be fully integrated into existing platforms and technologies. For instance, WebRTC can be integrated easily into a hosted VoIP system. By incorporating WebRTC into an existing hosted PBX platform, developers can access former networks of user agents for their WebRTC applications. This further allows developers to benefit from the key features of WebRTC on an enormously scalable level.  In simple words, by integrating WebRTC into the existing system, users can easily make video calls to any device capable of receiving them without the need to leave their internet browsers. 
  • Increased implementation: Over the years, the number of WebRTC enabled devices has increased greatly. Today, this technology is enabled on almost every device. It is an open-source project supported by some of the most popular internet names such as Google, Opera, and Mozilla. With WebRTC, developers have more options available to them when considering adding streaming video to their apps. 
  • Cost-effective solution: Since WebRTC is an open-source technology, there are no expensive licensing fees to run this tool. Whatever mechanism or tool is required to create WebRTC applications are available free of cost for the developers to use. The open protocol of WebRTC lets developers build applications that do not put extra load on the consumer in the form of additional costs at the level of the product. Since its introduction, WebRTC has become more easy-going with exclusive video codecs like H.264, allowing for the versatility of development options. No matter how advanced WebRTC is, it still allows developers to design apps with free technology.
  • Better efficiency: WebRTC technology provides a superior level of efficiency to developers and consumers alike. When looking at the development side earlier, it was quite difficult and technically demanding to capture and transfer real-time data from the computer’s webcam and microphone to other browsers. However, with the arrival of WebRTC technology, the entire process has become much easier and efficient. The ‘get user media’ command of WebRTC directs browsers to retain and transmit the particular data to other browsers simply. As the whole complicated process of capturing real-time media gets shortened into a single JavaScript command, the developers do not have to worry about creating extravagant media engines to run their apps. Also, when looking at the consumer side, WebRTC doesn’t require any downloads or plugins to run successfully. It works automatically in various browsers like Chrome, Opera, and Firefox. All these things make consumers worry-free when using WebRTC for video calling.  
  • Superior quality: WebRTC is powered by an open-source video codec known as VP8. A successor to VP7 and owned by Google from 2010, VP8 is an open and royalty-free video compression format developed by On2 Technologies. Its width and height measurements are 14 bits each, allowing for a maximum resolution of 16384 x 16384 pixels. Overall, the quality of VP8 is much better compared to H.264, which is a patented video codec and entails licensing fees. Currently, WebRTC videos facilitate everything, starting from usual video chats to business-grade communication apps. 
  • Easy customization: A video conference solution developed using WebRTC can be customized in any manner as per the user’s requirements. Businesses can customize it with all the necessary tools and combine it with other libraries to implement things like whiteboards (for online education purposes), integration with medical devices, translation for a language learning application, and more. 
  • No additional software needed: Another important reason to choose WebRTC is that it doesn’t require any additional software for efficient running. The technology is already built-in and supported by most popular browsers. WebRTC can also be used in native applications. The users don’t require to install any extra software to use WebRTC services. Moreover, any device with a compatible browser, camera, and microphone can smoothly run a WebRTC video calling solution.


So these are some of the key reasons to choose WebRTC technology. It is undoubtedly the most versatile real-time video technology that can be used to create everything from basic video chats to in-browser VoIP phones. Its ability to stream real-time video across browsers without plugins or downloads makes it even more attractive.
