Video Watermark Tool — Add Text or Image Overlay to Video
Watermarking video is essential for protecting intellectual property, branding marketing content, and establishing authorship of original footage. This browser-based video watermark tool lets you overlay a custom text or image on any video file, with full control over position, transparency, and styling — all processed entirely in your browser using FFmpeg-WASM.
For text watermarks, you can specify the text content, font size, color, and corner position (top-left, top-right, bottom-left, bottom-right, or center). Opacity control lets you create a subtle semi-transparent watermark that doesn't distract from the content or a more prominent opaque branding mark. For image watermarks, upload a logo PNG with an alpha transparency channel and position it precisely in any corner or center of the video frame.
Because the watermarking is performed by FFmpeg-WASM running in your browser, the video file never leaves your device. This is particularly important for confidential footage, unreleased content, or client work that should not be uploaded to third-party servers. The output video retains the original resolution and frame rate, with the watermark filter applied during re-encoding.
Branding Social Media Videos
Add your channel name, website URL, or logo to videos before posting on YouTube, Instagram, TikTok, or LinkedIn so viewers can identify and credit your content.
Protecting Copyright on Video Footage
Apply a semi-transparent copyright watermark to original video content before sharing previews with clients or distributing on public platforms.
Adding Client Branding to Deliverables
Overlay a client's logo on promotional or corporate video deliverables to produce branded assets ready for their marketing use.

Apply Watermark and Download
Click Apply Watermark. FFmpeg-WASM encodes the video with the overlay filter applied. Download the watermarked video when processing completes.
Text and Image Watermark Support
Add custom text overlays with adjustable font size and color, or position a PNG logo image with alpha transparency anywhere on the video frame.
Flexible Corner and Center Positioning
Place the watermark in any of the four corners or at the center of the frame. Padding offset controls keep the watermark a consistent distance from the edges.
Opacity / Transparency Control
Set watermark opacity from fully transparent to fully opaque to achieve a subtle branding mark or a prominent watermark depending on your intent.
Private Browser-Based Encoding
FFmpeg-WASM applies the watermark filter and re-encodes the video entirely in your browser. No video data is ever uploaded to any external server.
