Video conversion is generally legal if you own the copyright to the original video or have permission from the copyright holder. However, using video converters to download copyrighted content, convert videos without permission, or circumvent digital rights management (DRM) protection may infringe on copyright laws. Some video converters may also include features that enable downloading from streaming platforms, which can potentially lead to legal issues if used improperly. To stay on the safe side, always ensure you have the right to convert the content you’re working with and respect the terms and conditions of the source platform.
