What is the ToolDeck video watermarker?
ToolDeck Add Watermark is a free, browser-based tool that overlays an image or text onto your video. It runs on the multi-track editor, meaning your watermark is placed on a separate track above the main video. This allows you to easily resize, reposition, and fade the watermark without affecting the original footage.
When you export, the video and watermark are merged into a single MP4 file. Because the rendering happens locally in your browser using WebCodecs, you can watermark sensitive client work or unreleased videos without uploading them to a cloud server.
Why add a watermark to your video?
Protect your Copyright
Prevent people from stealing your footage. A visible watermark proves you are the original creator.
Brand Your Content
Add your company logo or channel name to every video to increase brand recognition and get free promotion.
Client Proofs
If you are a videographer, add a "PROOF" watermark before sending the video to a client for review. They will pay for the clean version.
Give Credit
If you are using stock footage or someone else's clip, add a text watermark to give them proper attribution.
How to add a watermark in 4 steps
- 1
1. Import your video
Drop your main video (MP4, WebM) into the editor above. It will land on the Main track (v1).
- 2
2. Add your Logo or Text
Import your logo (a transparent PNG works best) and it will automatically go to the Overlay track (v2). If you want a text watermark, click the "Text" tab on the left to add a text layer.
- 3
3. Position & Resize
Select the logo/text clip. Drag it in the preview window to the corner. Use the "Scale" slider in the Edit tab to make it smaller.

4. Set Opacity & Export
Lower the "Opacity" slider (e.g., to 50%) so the watermark is visible but not distracting. Stretch the watermark clip on the timeline to match your video length, then click Export.
What you get with this watermark tool
Image & Logo Watermarks
Upload your transparent PNG or JPG logo. It automatically lands on the Overlay track so it sits on top of your video.
Text Watermarks
Use the built-in text tool to add your channel name, handle, or copyright symbol (@YourName © 2024).
Adjustable Opacity
Do not block the video. Lower the opacity slider so your watermark blends in nicely without hiding the action.
Exact Positioning
Drag the watermark anywhere on the canvas. Place it in the top-right, bottom-left, or center.
Export up to 4K
Render high-quality H.264 MP4s at 1080p or 4K. The watermark is permanently burned into the video.
Private by design
No upload step. Your unreleased videos and branding assets are processed locally in your browser.
What this tool does well, and where it is limited
| Project type | Result | Notes |
|---|---|---|
| Adding a static logo to a video | Works perfectly | Use a transparent PNG and place it on the Overlay track. Adjust scale and opacity. |
| Watermarking for the whole video | Manual stretch | Drag the right edge of the watermark clip on the timeline to match the video length. |
| Moving/Tracking watermarks | Not supported | The watermark stays in one fixed position. You cannot animate it to move around. |
| Removing an existing watermark | Not supported | This tool only ADDS watermarks. Use the Video Cropper to crop out an existing watermark. |
| Tile watermarks (repeating) | Not supported | You cannot repeat the watermark all over the screen. It is a single overlay. |
Tips for the perfect watermark
Use a transparent PNG
A JPG logo will have a white or black square background. Always use a PNG with a transparent background for the best look.
Keep it subtle
A huge, solid watermark ruins the viewing experience. Keep it small, put it in the corner, and lower the opacity to 50-60%.
Match the length
Remember to stretch the watermark clip on the timeline. If you leave it at 5 seconds, the watermark will disappear for the rest of the video.
Top-right corner works best
Most platform UIs (like YouTube or TikTok) have buttons at the bottom and text at the top-left. The top-right is usually the safest place.
Add watermark FAQ
Adding the Watermark
How do I add a watermark to my video for free?
Drop your video into the editor above. Import your logo image (PNG/JPG) and it will appear on the Overlay track. Select the image, drag it to the corner in the preview, adjust the scale and opacity, and stretch it to match the video length. Finally, click Export.
How do I add a text watermark instead of a logo?
Open the "Text" tab on the left panel. Click "Caption" or "Subtitle". Type your text (like @YourName). Move it to the corner, reduce its size, and lower the opacity in the Edit tab.
How do I make the watermark semi-transparent?
Select the watermark clip on the timeline. Open the "Edit" tab on the right. Use the "Opacity" slider to reduce it to 50% or whatever looks best.
Why does my watermark disappear after 5 seconds?
When you add an image or text, it defaults to a short duration. Click and drag the right edge of the watermark clip on the timeline to stretch it until it matches your video length.
Formats and Quality
What image formats can I use for my logo?
PNG, JPG, JPEG, and WEBP. For the best results, use a PNG with a transparent background.
Will the watermark reduce my video quality?
No. The video is re-encoded during export, but the quality is preserved based on the resolution you choose (1080p or 4K).
Can I remove the watermark later?
Once you click Export, the watermark is "burned-in" to the video pixels. It cannot be removed later. Always keep a copy of the original video.
Privacy
Is my video uploaded to a server?
No. The entire process (combining the video and logo, adjusting opacity, and rendering) happens locally in your browser using WebCodecs. Nothing is uploaded.
Is this safe for client work?
Yes. Because there is no upload, your unreleased client footage and internal branding assets remain 100% private.
Your files never leave your device
There is no upload step and no account. The video, logo, and final MP4 are processed entirely in your browser using WebCodecs and WebAssembly. You can verify this by checking your browser's Network tab while rendering.
