Remove TikTok watermark

If the video is yours, the cleanest copy is the one you filmed. Save the clip to your camera roll before posting (TikTok’s editor has a save option for drafts and posts), or keep your original footage. Use this tool when the original is gone and all you have is the watermarked download.

“TikTok downloader” sites fetch videos from TikTok’s servers without the watermark. That breaks TikTok’s terms, strips the creator’s credit and depends on unofficial endpoints that break often. CleanMarks only works on files you already have.

Your video plays through a canvas in your browser. On every frame, each box you drew is repaired by one of four methods:

• Fill from edges: each hidden pixel becomes a distance-weighted blend of the pixels just outside the box, the same idea as FFmpeg’s delogo filter. It works best on small marks over simple backgrounds.
• Blur and pixelate hide a mark without pretending it was never there.
• Solid paints a flat colour, which is useful for letterbox captions.

The frames are re-recorded with the original audio into a new MP4 (or WebM on browsers that can’t record MP4). Nothing is uploaded, so rendering takes about as long as the video plays. Keep the tab open until it finishes.
