1.Does Online Uniconverter has Windows or Mac version?

If you want to get more service, you can download Uniconverter free from our official website. The software version is compatible with both Windows and Mac and it definitely has additional features that set it apart from the Online Uniconverter. Although we can’t say one is better than the other as each has it own perks but we can definitely say that Uniconverter and Online Uniconverter are worlds apart from other converters.

2.Is Online Uniconverter safe?

Yes, it’s totally safe. Uniconverter and online Uniconverter are protected against viruses and malware. You won’t encounter unwanted ads on their website either.

3. Is MP3 better than M4A?

M4A is like the next generation MP3, it has higher quality than MP3 and smaller size. M4A uses an Advanced Audio Converter which tends to reduce the amount of data lost during compression. MP3’s strong point is its minute size but at the expense of audio quality, M4A has an even tighter compression and retains most of its data which gives it both smaller size and a higher audio sound quality. As great as M4A is, it is not yet widely accepted and isn’t compatible with most devices. Again, MP3 came out with a good point; it is up to you, if you want small size and great quality or a format that can be played across all of your devices. You can still use converters to change the format anytime you like.
