TikTok — automatic watermark removal
ClipKeep fetches the original pre-watermark video file from TikTok's servers via the API. The downloaded MP4 has no TikTok logo overlay.
Twitter/X — no watermark by default
Twitter videos do not have watermarks. ClipKeep downloads the original MP4 directly from Twitter's CDN without any modification.
Other platforms
For Telegram, Reddit, Pinterest, and others, ClipKeep also downloads the original source files. Watermarks embedded into the video by the creator are part of the file and cannot be removed.
