Short answer: saving a clip to watch privately is how most people use downloaders and is rarely an issue in practice; reposting, sharing at scale or selling someone else's clips is where copyright problems start. This page is general information, not legal advice — laws differ by country.
Copyright protects the creator's right to copy and distribute their work. Keeping a copy of a publicly posted clip for yourself is a very different act from re-uploading it, and it's the re-uploading that creators and platforms act against.
RedGIFs' terms restrict scraping the platform at scale and building competing services on its content. Creators keep copyright over what they upload. Downloading a clip for yourself doesn't change who owns it.
RedGIFs Downloader doesn't host, cache or re-share any videos: the file travels directly from RedGIFs to you, and it only ever offers what RedGIFs already serves publicly. Deleted or private clips stay deleted. Whole-profile downloads go through a metered API (how that works).
No. Downloading through a tool like this doesn't notify the uploader. What matters legally is what you do with the file afterwards.
No. The file goes straight from RedGIFs to your device; our server only looks up the clip's file address and never stores the video.
Not without the creator's permission. The creator owns the copyright; reposting, selling or uploading their clips elsewhere can infringe it.
