Loader.to's Japanese video downloader works, but its Download button opens unrelated pop-ups
ja.loader.to is the Japanese version of Loader.to, a free online tool for converting YouTube playlists to MP3 and downloading media. Antivirus, Safe Browsing and connection checks found nothing harmful, and the parent domain is about 2,000 days old. In our test, though, the main Download control opened an unrelated external destination in a pop-up. One security vendor also lists the site as suspicious, and the page gives no contact email. Together these put it in Moderate Risk: usable with care, but the advertising is disruptive.

Investigation Brief
ja.loader.to is the Japanese version of Loader.to, a free online tool for converting YouTube playlists to MP3 and downloading media. Antivirus, Safe Browsing and connection checks found nothing harmful, and the parent domain is about 2,000 days old. In our test, though, the main Download control opened an unrelated external destination in a pop-up. One security vendor also lists the site as suspicious, and the page gives no contact email. Together these put it in Moderate Risk: usable with care, but the advertising is disruptive.
Why the score sits in Moderate Risk
When we clicked the site's Download control, it tried to open a pop-up to an unrelated external site. This is the clearest risk we found. Pop-ups like this come from ad networks, and the site does not control where they lead.
Gridinsoft currently classifies the site as a Suspicious Website and reports one blacklist detection. This is a security-vendor listing, not a customer complaint.
The site describes itself as safe and regularly tested, in contrast to dangerous converters. That is the site's own claim, and no independent evidence here confirms it.
Clean technical checks, anonymous operator
None of 93 antivirus engines flagged the site, the browser threat feed gave no warning, and the connection is properly encrypted. These results mean nothing harmful was detected; they do not prove the site is safe.
We found no direct contact email on the page, so it is unclear who runs the service. The page links to related downloader sites for SoundCloud, TikTok, Instagram and Twitter. It also links to browser extensions on the official Firefox and Edge add-on stores and lists an app.
Why the score is 52
A primary play, convert, continue, or download control opened an unrelated external destination. Coverage remains separate so missing sources cannot be mistaken for clean results.

If this is a scam — what it means for you
What happens when you press Download
A visitor who presses the primary Download button may be sent to an unrelated external destination in a pop-up, rather than straight to their file.
If you use this site, use a pop-up blocker. Close any new tab that opens when you press Download, and never install anything or allow notifications from those pages. If you want the browser extensions, get them only from the official Firefox or Edge add-on stores.

The plumbing behind the site — who registered it, how it’s encrypted, where it’s hosted, and where it links out. A valid certificate or a calm server doesn’t mean the business is honest — scam sites pass these checks too. Use this to corroborate the verdict, not to overturn it.

Domain & Encryption
Cloudflare DNS is used by legitimate and scam sites alike, so it does not identify who runs the site.
Certificate issued for loader.to.
A shared Cloudflare address answers for many sites, so it is not the site's own server and says nothing about who runs it.
Payment providers the page loads
None seen among the outside domains we saved.
Read from the first 20 outside domains the page loads and the shop platform it uses; the web server and platform rows are under Hosting & Technology. A payment script on the page does not prove the shop accepts that method at checkout, or that you are protected.
