www.lataayoutube.comは安全ですか？

You can download Youtube videos to your computer with lataayoutube for free. For a free service, it's actually very good. I don't know about the ads much in this site, but if you don't click them and/or use adblock and just download files from Youtube, it should be clean. I haven't encountered any malwares while using this site. I'm also glad that there isn't any pop-ups when first clicking something on the site (it has happend on other site that I've been using). Ads "might" be suspicious, and I wouldn't be surprised if you encounter some garbage that can be found on taboola, but as long as you don't click them, you should be safe when using the service. Feel free to use it. The site offers some options before you download it, which is nice. Also, it's a finnish site (owner seems to be foreigner though), but I think you can figure out how it works anyway if you are smart.

With AdBlock and Google Chrome, I have had no virus problems, redirects, or any other similar issues. This is a safe, free online YouTube downloader and converter with great features. In fact, this is the best free online YouTube converter I've ever used. Country restrictions may be somewhat of an issue though. If you can't read Finnish, constantly having to translate the page may become a nuisance. This site does contain some banner ads, but they are not annoying or misleading. Honestly, everything will still be okay if you turn off your ad blocker.
