What SoraWatermark is
SoraWatermark is a free online tool built for one job: removing watermarks from videos made with OpenAI Sora. You can upload MP4, MOV, or WebM files up to 100MB, and the AI automatically detects Sora watermark patterns and generates a clean mask. If you want more control, you can edit the mask by hand to fine-tune exactly which area gets cleaned. The tool also handles hidden watermarks, including C2PA metadata, and lets you save watermark removal presets for reuse on future videos. Although it is designed with Sora in mind, the same workflow applies to other video types. Export options cover HD and 4K, and the site says processing is encrypted to protect privacy. Content creators, marketing professionals, and social media managers are the main audience, and the tool is completely free to use.
