Add Watermark to Video

How to add a watermark to a video

1. Choose a video or drag it onto the box.
2. Pick Text, Logo image, or both.
3. Type your text, such as your name, channel or website, and choose the font, colour, size and opacity.
4. For a logo, choose a PNG or JPG and set its size and opacity.
5. Click a position in the grid, or drag the watermark on the preview to place it exactly.
6. Press Add watermark. The live preview shows the frames as they are watermarked.
7. Play the result and download it.

Text, logo or both

A text watermark is quick and easy to read, which makes it good for a handle like @yourname or a website address. A logo looks more professional and is the better choice for brands. A PNG with a transparent background blends best, because a JPG logo always brings its rectangle with it. You can use both at once, for example a logo in one corner and your website in another.

Making a watermark that works

• Opacity: 60 to 80% keeps the watermark visible without pulling attention from the video.
• Size: 4 to 8% of the video height suits most text watermarks. Logos look right at 10 to 20% of the width.
• Position: the bottom right corner is the usual spot. Avoid places where faces, captions or on-screen text appear.
• Effect: a soft shadow or an outline keeps white text readable on bright scenes. The dark box works on busy backgrounds.
• Protection: a small corner mark is easy to crop out. Repeat across the video tiles your text diagonally over the whole frame, which makes copying much harder. It suits previews and drafts sent to clients.

Output and quality

Because every frame changes, the video has to be re-encoded. High quality keeps the result close to the original. Very high gives a bigger file with the least loss, and Medium makes a smaller file for sharing. MP4 plays almost everywhere. WebM suits websites. You can also lower the resolution, and cut the video with the handles, which both make processing faster.

The watermark is placed in proportion to the frame. If you change the resolution, the text and logo scale with the video, so they look the same as in the preview.

What it can open

The tool reads MP4, MOV, WebM and MKV files with codecs your browser can decode: H.264, VP8, VP9 and AV1 in current browsers, and HEVC where your system supports it. Long 4K videos take time and memory. On a phone, a shorter clip or 1080p output is the safer choice.

Common uses

• Brand Reels, Shorts and YouTube videos with your channel name.
• Send watermarked previews to clients before they pay for the final file.
• Mark real estate, product or event videos with your company logo.
• Add a date or event name to family videos.

Privacy

Your video never leaves your device. The converter code downloads from the jsDelivr CDN the first time you use it, and from then on the work happens inside your browser tab. Nothing is sent to ToolsRiver, and we cannot see your files. When you close the tab, the copies held in memory are gone.
