FREE Video Converter by Convertio | Convert to MP4 MP3

Videos and music have become a part of our everyday lives. Whether you are a student, a professional, or just someone who loves to watch videos and listen to music, there is always a need for the right file format. Not every device supports all kinds of files. Sometimes, you download a video that will not play on your mobile. Other times, you want to extract just the audio from a video and save it as an MP3 file. This is where Convertio, a free online file converter, becomes very useful.
 

Convertio is an all-in-one solution that allows you to convert videos, audio, images, documents, PDFs, eBooks, and even software files into the format you need. The best part is that it is completely free and works directly in your browser. You don’t need to install any software, and you can convert your files quickly and easily.
 

In this article, we will discuss everything about the free video converter by Convertio, how it works, its features, why MP4 and MP3 are the most popular formats, and how this tool helps millions of people around the world.
 

Why Do You Need a Video Converter?

A video converter is a tool that changes a video from one file format to another. Imagine you downloaded a video in AVI format, but your phone only supports MP4. Without a converter, you cannot watch it. Similarly, you may want to upload a video online, but the platform accepts only certain formats. In such cases, a converter is the solution.
 

Here are the main reasons people use a video converter:

  • Device Compatibility – Not every device supports all formats. A converter makes your videos compatible with mobiles, laptops, or TVs.
     

  • Smaller File Size – Some formats are very large. Converting to MP4 can reduce the size without losing quality.
     

  • Extract Audio – If you only want the sound from a video, converting it into MP3 gives you just the audio.
     

  • Editing Needs – Video editors often require files in specific formats. A converter helps prepare files for editing.
     

  • Sharing – Smaller, common formats like MP4 or MP3 are easy to share on WhatsApp, Facebook, or email.
     

Convertio makes all of this very simple. With just a few clicks, your file is ready in the format you need.
 

Convertio: More Than Just a Video Converter

Convertio is not just a video converter. It is a multi-purpose online conversion platform. Along with videos, it allows you to convert:
 

  • Audio files (MP3, WAV, AAC, OGG, FLAC, and more)

  • Image files (JPG, PNG, GIF, BMP, TIFF, SVG, etc.)

  • Document files (DOC, DOCX, TXT, RTF, HTML, and more)

  • PDF files (convert PDFs to Word, Excel, or images and vice versa)

  • eBooks (EPUB, MOBI, AZW3, FB2, etc.)

  • Software and Executable files

  • Compressed files (ZIP, RAR, 7Z, TAR, etc.)
     

This means you don’t need separate tools for each type of file. With Convertio, you get everything in one place.
 

Why MP4 is the Most Popular Video Format

When talking about video conversion, the most common format people choose is MP4. But why is MP4 so popular?
 

  • Universal Compatibility – MP4 files work on almost every device, from smartphones to smart TVs.

  • Smaller File Size – MP4 compresses video efficiently, so you save storage space.

  • High Quality – Even with compression, MP4 maintains very good video and audio quality.

  • Streaming Support – Platforms like YouTube, Facebook, and Instagram prefer MP4 for streaming.

  • Editing-Friendly – Most video editing software supports MP4.
     

That is why Convertio users often choose to convert their videos into MP4 format.
 

Why MP3 is the Most Popular Audio Format

Just like MP4 for videos, MP3 is the most popular format for audio. It has been around for decades and is supported by every device.
 

  • Smaller Size – MP3 files are lightweight and perfect for storage.

  • Universal Support – Any phone, computer, or music player can open an MP3.

  • Good Quality – Even though compressed, MP3 still provides clear sound.

  • Easy Sharing – MP3 files are easy to share through email or messaging apps.
     

Convertio makes it very easy to extract MP3 audio from any video. For example, if you like a music video on your computer, you can quickly convert it to MP3 and listen to it anywhere.
