Whether your 3GP file is a grainy video or a saved clip from the early 2000s, these files were the standard for mobile data for so long. Fast forward to now, you might face a file format not supported, so converting 3GP to MP4 comes up. Since MP4 is the universal format for videos today, this guide shares with you the best 5 ways to convert 3GP to MP4 format, from desktop software and online tools to mobile solutions. Enjoy a seamless playback on everything!

Important Tips When Converting 3GP to MP4

Before clicking the convert button, understand first the files you are handling. Here are some tips that will help you get the best results without degrading the quality of your footage:

  • Maintain Original Resolution. Do not upscale a tiny 3GP file to 4K, as it will result in a blurry mess with a large file size.
  • Check the Audio Codec. Many 3GP files use AMR audio, which some players will struggle to play with, so always have AAC as your codec for maximum compatibility.
  • Use Batch Processing. If you have a bunch of clips, look for tools with a batch conversion feature.
  • Make a Backup. Always keep your original file until you have ensured your MP4 video file plays correctly.
  • Watch for Watermarks. Check if the tool includes a watermark, since it can be annoying on the final result. Or you can remove watermark from a video manually.
