You can watch anime for free on several websites that offer a mix of legal and fan-supported streaming options. Here are some of the best free anime streaming sites in 2025:

• Crunchyroll: One of the largest legal anime sites, offering a huge library of licensed anime with Japanese audio and multilingual subtitles. Some content is free with ads, and they provide high-definition streaming.

• VIZ: An American anime publisher site with free content available, especially for popular titles like Naruto and Jujutsu Kaisen, with some content requiring subscriptions.

• AniWatch.to: A free anime streaming site where you can watch and download subbed or dubbed anime in HD quality without registration or payment. It has minimal ads and emphasizes safety.

• AnimeHeaven and GoGoAnime: Popular fan sites offering a vast collection of subbed and dubbed anime. These sites have ads, and since they operate without official licenses, a VPN and ad blocker are recommended for safer use.

• 9anime: Another free site providing English subbed and dubbed anime with HD quality and fast streaming. It's widely visited but users should be cautious about unofficial copies.

• Other legal options include Tubi TV, Anime-Planet, and YouTube channels with official anime uploads.

These platforms let you watch anime for free, though some might use ads for monetization, and certain regional restrictions or subscriptions might apply in cases like Crunchyroll. This gives a good mix of safe, legal, and popular fan sites where anime is free to watch online.
