Video Watermark Tool Community

What this tool does

This site already has a photo watermarking tool — this is the real video equivalent, a genuinely different technical problem since a watermark needs to be drawn onto every one of a video's many frames and the whole thing re-encoded, not applied once to a single image. This tool plays your uploaded video frame by frame onto a canvas, draws your chosen text or logo watermark onto every single frame at your chosen position, size and opacity, and captures the canvas output frame-by-frame into a genuinely new, watermarked video file using the browser's native recording pipeline.

How to use it, step by step

1. Upload your video.
2. Add a text watermark, upload a logo image, or both, and set position/size/opacity.
3. Click Render — the tool draws the watermark onto every real frame and re-encodes the video.
4. Download the watermarked video file.

Tips from the guide

• Rendering happens by capturing the canvas output in real time as the video plays through once, so a longer source video takes proportionally longer to process — this is expected, not a stall.
• The exported format depends on what your browser's video recording pipeline supports (commonly WebM); if you need a different container format, a separate conversion step may be needed afterward.
• A larger, higher-opacity watermark is harder to crop or edit out, which matters if the goal is real protection against reuse rather than just branding.

Common mistakes to avoid

• Expecting the export to preserve the exact original file format automatically — the output format follows what the browser's recording pipeline produces, which may differ from the source video's original format.
• Using a very small, low-opacity watermark and expecting it to meaningfully deter reuse — a bigger, higher-opacity, harder-to-crop placement offers more real protection if that's the goal.
• Not checking audio is preserved correctly in the exported file — confirm the rendered output's sound plays back as expected before relying on it.

Who uses it

• Content creators sharing preview or draft videos. Mark ownership on every frame before sharing a work-in-progress publicly.
• Small businesses protecting promotional video content. Add a persistent brand watermark before distributing a video online.
• Anyone sharing a video clip they want clearly attributed. Bake in a name, handle or logo that stays with the video wherever it's shared.

How to ask a question people can answer

A good thread on the Video Watermark Tool saves everyone time. Start with a title that names the exact problem, such as the input you used, the result you expected and the result you got. A title like “Not working” is hard to answer, while a title with the specifics gets replies quickly.

• Say what you tried. List the steps you followed and any settings you changed, so replies do not repeat what you already did.
• Share a small example. A short sample input and the output you saw is worth more than a long description. Remove anything private first.
• Mention your setup. Your device, browser and whether you are on a phone or a computer can explain many odd results.
• One question per thread. Separate topics get clearer answers and are easier to find later with the search box above.
• Come back and reply. If a suggestion worked, say so and upvote it, and if you found the fix yourself, post it for the next person.
