Add Watermark to Video

About Add Watermark to Video

Add a professional touch or protect your content by adding a watermark to your videos using our Free Online Video Watermark Tool. Choose between a custom text watermark or an image watermark (like your logo). You can easily adjust the watermark's position, size, font (for text), color, and opacity directly on a preview of your video's first frame. The final video's watermark will match the size and position you set in the preview.

Processing is done entirely in your browser with FFmpeg.wasm, ensuring your video files are never uploaded to any server. It's private, fast, and secure. Track the progress by seeing how many frames have been processed. The original audio track is maintained in the final watermarked video.

Features:

• Client-Side Processing: Securely processes videos in your browser. Your files remain private.
• Text & Image Watermarks: Add either custom text or upload your own image/logo.
• Interactive Preview: Drag, drop, and resize your watermark on a preview of the video's first frame.
• WYSIWYG Scaling: The watermark size in the final video accurately matches the preview.
• Text Customization: Select font family, adjust size, pick color, and set opacity for text watermarks. Style changes preserve position/scale.
• Image Customization: Upload common image formats (PNG, JPG) and adjust opacity.
• Audio Preservation: Keeps the original audio track intact.
• Easy Download: Get your watermarked video in MP4 format.
• Frame-Based Progress Tracking: Monitor the watermarking process with frame count (e.g., Frame 150 / 1200).

How to Use:

1. Load Engine: Wait for the video processing engine (FFmpeg) to load.
2. Upload Video: Drag and drop your video file or click "Select Video".
3. Configure Watermark: Choose type, enter text/select image, set font, size, color, opacity.
4. Position & Size Watermark: Drag and resize the watermark overlay on the preview image.
5. Add Watermark: Click the "Add Watermark" button.
6. Wait & Preview: Monitor progress. Once done, a preview of the watermarked video (matching the preview size) will appear.
7. Download: Click "Download Watermarked Video".
8. Share (Optional): Click "Share Tool".

Note: Processing happens in your browser. Larger/longer videos require more time and system resources (CPU/Memory).

Quick Answer

To watermark a video, upload it here, choose a text or image watermark, then drag and resize it directly on a preview of the first frame — the position and size you set are exactly what the exported video gets. Set the opacity to somewhere around 40–70 % so the mark is visible without hiding the footage, and place it in a corner where a crop is unlikely to remove it. The tool burns the watermark into every frame with FFmpeg.wasm running in your browser, so the video is never uploaded, the original audio is preserved, and the export carries your mark only — miniwebtool adds nothing of its own.

Common Use Cases

Branding videos with a logo

A small logo in a corner keeps your brand visible when a clip is re-shared, embedded or downloaded.

Discouraging unauthorised re-use

A visible watermark makes stolen footage obvious and much less attractive to re-upload.

Marking drafts and review copies

Overlay text such as DRAFT, PREVIEW or CONFIDENTIAL so an unfinished cut is never mistaken for the final version.

Adding a social handle or website

Putting @yourhandle or your URL on the frame means viewers can find you even if the caption is stripped.

Attribution and copyright notices

A photographer or videographer credit and a copyright line travel with the file itself.

Course and tutorial content

Paid lessons are often watermarked with the platform name or the student's identifier to discourage sharing.

Frequently Asked Questions

How do I add a watermark to a video?

Upload your video, choose a text or image watermark, style it, then drag and resize it on the preview of the first frame. Click Add Watermark and download the MP4 when processing finishes. The watermark is burned into every frame.

Should I use a text or an image watermark?

Use text for a name, a social handle, a URL or a notice such as DRAFT, since it stays crisp at any size. Use an image when you need an actual logo. For images, a PNG with a transparent background looks far better than a JPG, which will show a solid rectangle.

Where should I place the watermark, and how visible should it be?

A corner with a small margin is the usual choice because it stays out of the action but survives most crops. Opacity between about 40 and 70 per cent keeps it legible without dominating the frame. If you are mainly worried about theft, place it closer to the centre where it cannot be cropped out.

Will the watermark in the exported video match what I see in the preview?

Yes. The tool scales the position and size you set on the preview to the video's real resolution, so the exported frame matches the preview proportionally.

Is my video uploaded to a server?

No. FFmpeg.wasm runs inside your browser tab, so both the video and the logo image stay on your own device.

Can the watermark be removed later?

No. It is burned into the pixels of every frame, which is what makes it effective. Keep your original unwatermarked file if you may need a clean version.

Is the audio kept?

Yes. The original audio track is preserved and stays in sync; only the picture is modified.

Does miniwebtool add its own watermark?

No. The only mark on your exported video is the one you added yourself. The tool is free and requires no account.

Why does watermarking take longer than other video tools?

Every frame has to be decoded, composited with the overlay and re-encoded, so the work scales with the length and resolution of the clip. The progress counter shows which frame is being processed so you can see how far along it is.
