About the formats

File extension .mp4
Category Video file formats
Developed by MPEG (Moving Picture Experts Group)
Mime type video/mp4

Format description

MP4 (short for MPEG-4 Part 14) files store multimedia - video, audio and subtitles. Websites frequently use them for displaying videos because the MP4 format is universally supported.
However, newer video formats, such as WebM, produce smaller file sizes with almost no quality loss. Therefore, you can free up storage by converting your videos to WebM.
File extension .avif
Category Image file formats
Developed by AOMedia (Alliance for Open Media)
Mime type image/avif

Format description

The AV1 Image File Format (AVIF) is a new format which promises better compression and smaller file sizes than JPEG, PNG, WebP, and all other current image formats on the web. Based on the generic HEIF image format, AVIF supports alpha transparency, HDR, lossy and lossless compression. AVIF is already being used by Netflix and Microsoft.

Which browsers support AVIF and since when?

In 2024, all major browsers can render AVIF images. Support in Google Chrome and Chromium-based browsers (like Microsoft Edge, Brave, and Opera) has landed in late August 2020. Firefox can display AVIF images from version 93, released in October 2021. Apple's Safari can finally recognize and show AVIF images starting with iOS 16, released in September 2022.

This app is exactly what I asked for and is super easy to use. I am not a big time computer wizard so I need apps that do what they say do in a straightforward process. This app does just that! I love it and will continue to use it and will advise others of it as well. Good job to the owners/developers! And, sincere THANK YOU!

AMAZING! This is the perfect file converter! The first thing I used it for was to convert WMV files to MP4 and it worked flawlessly. I then realized it supports all kinds of formats and is basically unlimited. The UI is very user-friendly and super easy to navigate. Incredible app, MConverter!
