Discover Top AVI to MP4 Converter Tools

June 23, 20251 view


Today’s media practically runs on videos. From content to advertisement, everything is fed to us in the form of clips, reels, or YouTube videos, and oftentimes, people save these videos on a device for casual viewing. That has been true for ages, much like in 1992 when Microsoft released AVI, an audio-video interleave that was the most popular of its kind, if not the first. The problem with AVI, however, is the massive space the videos in this format take. So, here are my top picks for AVI to MP4 Converter tools.

Top 5 Popular AVI to MP4 Converter Tools

Scouting for the best free software for AVI to MP4 conversion had me going through multiple review forums like Reddit, after that, all of the most popular picks had to be reviewed. Here is a breakdown of all of my findings.

Top 5 Popular AVI to MP4 Converter Tools

Converter APP

The first tool that will come up in your search results is probably the Converter App’s AVI to MP4 tool. It is a free, easy-to-use online service that lets you convert videos in the AVI format to the much more widely supported and space-saving MP4 format.

Converter App

You can upload your videos and, with just a few clicks, you can get a high-quality MP4 version without having to install a thing, which is an added benefit on the space-saving front.

Features

  • No Download: It is a Web-based tool; therefore, there is no installation required.

  • Supports Batch Conversion: You can convert multiple AVI files to MP4 files at a time.

  • Quality Preservation: It is ranked fairly high amongst online tools for AVI to MP4 without quality loss.

  • Format Support: It provides users with multiple output format options (MP4, MOV, MKV, etc.) to choose from.

  • Ease-of-Use: Has a simple drag-and-drop upload functionality.

  • Conversion Size: Supports conversion of videos up to 1GB in size.

Pros

  • User-friendly interface.

  • Fast conversion speeds.

  • No watermarks.

Cons

  • Limited advanced editing options.

  • Requires a stable internet connection.

As a first-time user, I found it pretty easy to navigate and use. It worked super quickly, which is another plus because I am not a fan of any tool that lags. I even used the batch processing feature to convert some old home videos to send to my parents; it worked like a dream.

The output quality turned out superb as well, without the watermark, what more could one need?

OnlineFreeConvert

Another simple yet powerful tool is OnlineFreeConvert. It’s like the developers took multiple keywords and decided to make it into a converter, so you know it means business. It’s simple enough to understand. The name gives it away. It’s online, it’s free, and you can use it to convert files from one format to another.

OnlineFreeConvert

The reviews suggest that the results are high-quality as well, and it works on all major devices and browsers. The file handling is dealt with securely, and all the data is automatically deleted after conversion.

Features

  • No Downloads: The platform is completely online with no downloads, which is a space-saving feature.

  • File Size: Supports file sizes up to 1 GB (free version).

  • Customizability of Output: Facilitates customization for resolution, bitrate, and frame rate.

  • Supported Formats: It supports over 500 file formats for conversion.

  • Space Saving Options: Has the option to compress files during conversion.

  • History: Provides conversion history for quick re-access.

Pros

  • No installation needed.

  • Supports multiple input/output formats.

  • Free to use.

Cons

  • File size limitation on the free version.

  • Conversion speed depends on the internet.

I found it a perfect companion for on-the-go conversion needs. It converted my AVI videos to MP4 fairly quickly. The interface was simple, just how I like it, and the customization options let me tweak the video quality before saving it onto my device.

I will say that the size limit can be bothersome. I wasn’t able to convert any video larger than 1GB, which is a bit restrictive.

HandBrake

If you’re someone who prefers more advanced features, surgical precision, and more control over the outcome of your video conversion, use HandBrake. It is a free, open-source video converter compatible with Windows, Mac, and Linux, letting you convert nearly any format into more modern versions like MP4 or MKV.

HandBrake

It has advanced options for video quality, like bitrate and codec, that you can adjust however you like, and it has the ability to compress large videos without losing much quality. If you’re searching for how to batch convert AVI to MP4, your search ends here. It is completely free to use with no ads or hidden fees.

Features

  • Advanced Encoding: It is an open-source software with advanced video encoding options.

  • Batch Conversion support: Users can convert multiple files at a time.

  • Convenience: HandBrake has built-in device presets for quick conversion.

  • Controlled output: HandBrake gives users detailed control over codecs, frame rates, and resolutions.

  • Subtitles and chapter support: The converter can handle those extra pieces of information in the video file, not just the video and audio.

  • Input format support: It supports a wide range of input formats beyond AVI.

Pros

  • Free and no ads.

  • High customization and quality control.

  • Active community and updates.

Cons

  • Slightly steeper learning curve.

  • The interface may seem complex for beginners.

I’d say that HandBrake has, to some degree, “converted” me from basic conversion tools to more precise ones. It is my go-to when I want a more detailed outcome from my video conversions.

I used it for batch conversion as well, and it went as smoothly as can be. I recommend new users take their time familiarizing themselves with it because, for me, there was a bit of a learning curve. Once I got the hang of it, it was smooth sailing.

Movavi Video Converter

Movavi Video Converter is something that bridges the gap between novice and expert users because it is a converter that both of them can use. It is fast, user-friendly, and can easily work for Mac and Windows users alike. It supports a massive collection of formats and has a built-in video editor, much like HandBrake, but simpler.

Features

  • Format Support: Supports over 180 formats, including but not limited to MP4, MKV, AVI, MOV, FLV, and DVD.

  • Super Fast Speed: Ultra-fast conversion with hardware acceleration.

  • Editing features: Movavi has a built-in video editor that includes trimming, cropping, and effects to edit the video before downloading to your device.

  • Simplicity: Movavi has a simple drag-and-drop interface.

  • Convenience: It has automatic conversion presets for different devices, so you don’t have to overthink what settings to go for.

  • Upscalability: AI-based upscaling is available for improving video quality.

Pros

  • Intuitive and polished interface.

  • High-quality output.

  • Batch processing is available.

Cons

  • Paid software (free trial available).

  • Some features are locked behind a paywall.

Using Movavi is similar to having someone explain rocket science in a language a 5-year-old could understand. I understood the complexity behind all the features, but they were presented so simply that I felt like anyone could use them. The video editing tools came in handy as well, the only downside for me was that it’s paid.

CloudConvert

CloudConvert’s AVI to MP4 Converter is a flexible online tool that makes converting AVI videos to MP4 simple and reliable, right from your browser. It’s perfect for anyone who wants great video quality without installing extra software.

CloudConvert

Whether you’re converting one video or a whole batch, CloudConvert gives you advanced options to fine-tune things like resolution, codec, and bitrate, or you can just stick with the default settings for quick results. It also takes privacy seriously, deleting your files after conversion, so you can use it with peace of mind.

Features

  • Format Support: It is a cloud-based tool with support for over 200 formats.

  • Integrability: Integration with Google Drive, Dropbox, and OneDrive.

  • Controlled output: Option to adjust video codec, resolution, and aspect ratio.

Pros

  • No software installation needed.

  • Supports large files and batch conversion.

Cons

I’ve found CloudConvert to be a fantastic option, especially when I’m working with files stored in the cloud. It integrates so smoothly with my cloud storage services that moving videos and documents between platforms feels almost effortless.

I also really appreciate the clean, intuitive interface. It makes the whole process of converting files fast and frustration-free. The quality of the conversions is excellent, which is always important to me when dealing with larger or high-res files. The only downside for me was the paywall restriction.
