How to Add a Logo Watermark to a Video for Free (No Signup, No Software)

If you post video clips online — product demos, tutorials, social reels, portfolio work — an unbranded video is an easy asset for someone else to re-upload as their own. Watermarking with your logo is the simplest way to keep your name attached to your work, but most tools that offer it either want a monthly subscription, stick their own watermark on top of yours, or require installing desktop software like FFmpeg and running command-line flags.

Video Watermark is a free browser tool that overlays a logo onto a video and gives you back a clean MP4/WebM file — no account, no upload limits beyond a sane file size cap, no leftover branding from the tool itself.

What it does

You upload two files: a video (MP4, MOV, WebM, MKV, AVI, or M4V, up to 100MB) and a logo image (PNG, JPG, or WebP, up to 5MB — PNG with a transparent background works best). The tool composites the logo onto every frame of the video server-side and hands back the finished file.

You control three things:

• Position — pin the logo to one of the four corners or dead center
• Size — how large the logo appears, as a percentage of the video frame
• Opacity — how transparent the watermark is, so it can sit subtly in a corner instead of fighting for attention

How to use it

1. Go to nutilz.com/video-watermark
2. Drop in your video file
3. Drop in your logo (a transparent PNG gives the cleanest result — no white box around it)
4. Pick a corner (or center) for the watermark
5. Adjust size and opacity until it looks right in the preview
6. Click apply, wait for processing, and download the watermarked video

That's the whole flow. No export presets to configure, no rendering software to install.

Why it's useful

• Freelancers and agencies sending draft cuts to clients can mark them "preview" or brand them before final delivery, without touching editing software.
• Course creators and educators can brand screen-recorded lessons consistently without re-exporting from their recording tool each time.
• Social media managers repurposing raw footage across platforms can stamp a handle or logo on every clip in seconds instead of re-opening a video editor per file.
• Anyone protecting original footage from being re-shared without credit gets a lightweight deterrent that doesn't require professional editing skills.

It's not a replacement for a full video editor if you need multi-layer effects or animated watermarks — but for the common case of "put my logo in the corner of this video," it's faster than opening Premiere or Final Cut for a one-off task.
