The legality of reading manga online depends on the source. Legitimate platforms with proper authorization make it legal. But most random sites offering free manga are likely illegal and can get you in trouble.
Websites like KissManga and MangaFox are often used. They offer a large collection and are user-friendly. However, be aware of potential ads and the legality of some content.
It depends on the website. If the website has the proper authorization from the publisher or author to distribute the novel for free, then it is legal. For example, if the publisher is running a promotional campaign and has chosen a particular website to offer 'Twisted Palace' for free, that's fine. However, many websites that offer free e - books without permission are operating illegally. These sites are often involved in copyright infringement, which is not only unethical but also against the law.
Many libraries offer e - book lending services which are legal. They have agreements in place with publishers. So, if you access 'The Hobbit' through your library's online platform, it's completely legal. But beware of some random websites that claim to offer free books without any clear authorization. These are likely to be operating illegally and may also expose you to security risks like malware.
