Mark the fixed or semi-transparent logo on your video and remove it automatically. Free, no sign-up, files aren't stored.
Whether you're removing a downloader's watermark from a saved clip or a channel's bug from a screen recording, you draw one or more boxes over the logo — optionally limited to just the seconds it appears — and our AI reconstructs each frame underneath using the surrounding footage, so the cleaned video plays back without a visible gap where the mark used to be.
Is it free?
Yes, no account needed, no payment required.
Does my video get uploaded anywhere?
Yes, watermark removal happens on our server — but your video is deleted immediately once processing is done, it's not stored.
Which video formats are supported?
mp4, mov, webm, and mkv, up to 300MB and 60 seconds.
Do I need to sign up?
No.
Can it remove a moving logo?
The watermark needs to stay in a fixed position on screen; you can optionally apply it only during a specific time range, but it doesn't track a moving/animated logo.
Can I remove more than one watermark from the same video?
Yes, you can draw as many marked regions as you need — for example a logo in one corner and a text overlay in another — and each region can have its own time range if the watermarks don't appear at the same time.
How long does processing take?
It depends on the clip's length and resolution — since the AI analyzes and reconstructs every single frame behind the watermark, longer or higher-resolution clips take more time. You can leave the tab open; processing runs on our server, not your browser, and the page updates automatically when it's done.
Can I use this on any video I find online?
No — only use it on videos you own or have the rights to. Removing a watermark from content you don't have permission to use can violate the original creator's copyright, and Stelluna is intended strictly for personal use on your own footage.
