Well, it's always a nagging yet controversial question. Based on most FLVTO reviews throughout the Internet, people's reactions toward this question can be polarized. Quite a few people believe that FLVTO is an untrustworthy website that gives out viruses, malware and potential threats, while the others argue that it's safe to use.
In my humble opinion, the website itself is totally safe as it has been verified by some Web Security Checkers, such as Web Of Trust (WOT), Google's Safe Browsing Site Status, Trend Micro Site Safety Center, Website Safety Check, VirusTotal, etc.
However, the crucial threat to safe use of FLVTO music converter is actually the annoying pop-ups, banners, redirects and other ads of this kind, which will bring unexpected potential risks to those non-tech-savvy people. It's understandable that ad is the only source of revenue for FLVTO webmaster to run and maintain the free service, but it becomes increasingly invasive to get people freaked out.
Based on my own experience, FLVTO is safe and works well with an ad-blocker installed. So the best practice to safely use FLVTO is, installing an ad blocking program or extension, DO NOT CLICK any overlooked ad or pop-up. Similarly, you can check how to stop pop-ups on streaming sites for reference.
As you know, FLVTO.biz is an established online YouTube converter that allows people to download and convert YouTube video to high-quality MP3 & MP4/AVI files at no cost. So strictly speaking, FLVTO essentially infringes YouTube's terms and conditions, and is almost certainly illegal if you do not own the copyright or have permission from the copyright holder or distribute and benefit financially from the download.
You may find that the official website FLVTO.biz has been disappeared in the SERPs due to DMCA takedown notice claimed by RIAA (Recording Industry Association of America) member companies. Currently, all of the alleged FLVTO websites with different domain names are FAKE. The fact is you can still visit FLVTO.biz from bookmark or manually typing the address in browser.
Generally, a user probably won't get into trouble with the copyright law for using FLVTO to download YouTube songs and videos for personal fair-use, and the case may vary in different countries. But as a precaution, you have to figure out whether it's legal to download YouTube video in your region beforehand.
In my own case, with AdBlock extension installed, FLVTO really worked for most YouTube videos (private and restricted videos are excluded). What you need to do is, just copy and paste YouTube video URL into the link box. FLVTO is capable of converting YouTube video to 320kbps MP3 or 1080p MP4.
But sometimes, you may run into FLVTO not working issues. There were also quite a few downloaded MP3 that didn't have sound. In addition, video longer than 2 hours is not supported by the online converter. I've no idea if it's caused by the music copyright infringement or sort of a marketing method.
I was advised to download and install its desktop MP3Studio YouTube Downloader, which gives more format options and further supports for Facebook, SoundCloud, Vimeo and Instagram. But here came the bummer, if you didn't pay attention, you would be misled to install the optional offers - Avast antivirus and Opera browser.
When I completed the installation, I tried to save videos from YouTube and Facebook. Not sure if it was my settings problem, it failed to download any video. To eliminate the network issue, I also took another shot on the company computer. Yeah, it worked this time. But it only offered 3 free conversions unless you upgraded and subscribed the application. So when FLVTO doesn't work as usual, you can wait for the fixes or contact the official support for help.
In a nutshell, despite a few minor flaws, FLVTO indeed gets the job done with an ad-blocker installed, though not really the best site out there. By comparison, I would recommend Free HD Video Converter Factory, a safe and clean program that allows you to download 720p/1080p/2K/4K/8K videos from YouTube, Facebook, Vimeo, SoundCloud, MixCloud and 300+ popular websites, absolutely free of cost. Let's see how it works.
