W-Agent

W-Agent is a free, no-install web tool that removes subtitles, logos, watermarks and text overlays from videos and images using AI inpainting, with auto detection or manual masks for finer control.

W-Agent is a browser-based cleanup tool for removing unwanted overlays from videos and still images. It targets burned-in subtitles, channel logos, watermarks and stray text, and fills the cleared area using AI-assisted inpainting so the background looks continuous. There is nothing to install, and the service is described as free to use without hidden fees or subscriptions. The workflow has three stages: upload a file, run the removal, and download the result. Videos can be MP4, MOV, WebM, MKV or AVI, with limits of two minutes, 2560x2560 resolution, 60 frames per second and 500MB. Images in JPG, JPEG, PNG and WebP are also accepted. Uploaded files are said to be processed securely and deleted automatically once the job finishes. Control over the result comes from three modes. Auto detects overlays on its own and suits marks that repeat across the frame or drift around. Bounding Box and Brush let the user mark an area by hand, which the site recommends whenever the overlay stays fixed in one spot because it gives the best visual quality. For video, masks can be limited to specific time ranges, which helps when a logo or caption appears only in part of a clip. The audience is broad: creators reusing their own footage, editors cleaning up source material, and anyone who needs to strip a caption or mark from a clip without opening desktop software. Output quality depends on the source footage and how complex the mask is, so busy or detailed backgrounds behind an overlay are harder to reconstruct convincingly. Among alternatives, W-Agent sits between heavyweight editors that offer manual content-aware fill and generic one-click watermark removers. Its focus on video, mask scoping by time and the absence of a signup or install step make it a quick option for short clips, while the length and size caps point longer projects toward other tools. Users should only process material they have the rights to modify.
