Why watermark videos?
An image watermark helps protect clips, reinforce branding, and signal ownership before sharing previews, social posts, or client deliveries — without re-editing in desktop software for a quick pass.
Benefits of image watermarks
- Branding: Keep logos visible on exports.
- Deterrence: Discourage casual reuse of previews.
- Flexible layout: Move, resize, and tune opacity in the preview.
- Common outputs: Export MP4, WebM, or MOV when supported.
- Local processing: Designed to run in your browser without uploading your files to our servers.
How this watermark tool works
You supply a video and a raster image. The tool composites the image onto each video frame at your chosen rectangle (normalized position and size), then re-encodes a new file. This page supports image watermarks only — not text typed in the browser.
Workflow (overview)
- Video: Load the source clip.
- Image: Load the watermark artwork.
- Layout: Position, resize, opacity, stretch or fit.
- Format: Choose MP4, WebM, or MOV for export.
- Export: Encode and download.
Watermark facts
Useful context before you export.
Key points
- A burned-in watermark becomes part of the pixels — removing it cleanly usually requires the non-watermarked source.
- PNG with alpha can preserve transparency; opaque images cover video underneath.
- Export quality depends on source footage and encoder settings.
- Processing time scales with duration and resolution.
- One video and one watermark image per run.
Best practices
Guidelines for clearer results.
Layout and quality
- Avoid covering faces or critical on-screen text.
- Lower opacity or smaller size if the mark distracts from content.
- Use Fit to preserve logo aspect ratio inside the box; use Stretch to fill the box exactly.
- Start from high-quality source video when possible.
- Keep an unwatermarked master when you might need edits later.
Common use cases
- Previews: Client or portfolio samples before full delivery.
- Social: Logo on short clips for feeds or stories.
- Stock / licensing: Visible attribution on review copies.
- Internal: Draft marks on training or meeting recordings.
- Creators: Channel or brand bug on corner.
Technical overview
Each frame is decoded, your watermark image is drawn into a target box with optional opacity and stretch-or-fit behavior, and the result is encoded into the selected container. Audio is typically copied or re-encoded with the export pipeline.
Process
- Load: Video and image are read in the browser from your files.
- Composite: Per frame, the overlay is drawn at the rectangle you defined (with snapping to edges/center when close).
- Encode: A new video file is written with codecs appropriate to MP4, WebM, or MOV.
- Download: You save the watermarked file locally.
- Privacy: Processing is intended to stay on your device without uploading your media to our servers.

Frequently asked questions
Does this add text watermarks?
This tool composites a raster image you provide. For text, use a graphic or image with your text, or use a dedicated text tool elsewhere.
Can I remove the watermark later?
Not from the exported file without the original — the watermark is baked into the video. Keep your master file if you need an unmarked version.
Will quality stay the same?
Re-encoding introduces generational loss like any export. Start from the best source you have.
What image formats work?
Common formats such as PNG and JPEG work when the browser can decode them; PNG with transparency is a common choice for logos.
Is my content secure?
Processing is designed to run locally in your browser without uploading your video or image to our servers.
Can I watermark many videos at once?
Process one video per run; repeat with different files or settings as needed.
What output formats are available?
You can typically choose MP4, WebM, or MOV depending on support and fallback path.
