Why People Use PixDuplicate's Video Watermarker

Text That Looks How You Want

Pick your font size and color, add a background box if you need contrast, and dial in the padding. Good for copyright lines or a channel name.

Logos with Transparency

Drop in a PNG with a transparent background and it sits on top of the video without a visible box around it. Adjust scale and opacity to taste.

Anywhere You Want It

Five preset positions for the corners and center, or open the visual picker and drag the watermark exactly where you want it.

Nothing Gets Uploaded

Everything runs in your browser. Your video never leaves your device—no servers, no cloud.

Preview Before You Process

See exactly how the watermark will look on the actual video before you commit to a full run. No surprises after rendering.

Control When It Shows

Set a start and end time so the watermark only appears on part of the video. Or leave it on the whole thing.

How the Video Watermarker Works

Branding your videos—without sending them anywhere

Step 1: Add your video and watermark

Drop in your video file (MP4, WebM, or MOV up to 2GB), then either type out some text or upload a logo image (PNG, JPG, SVG, or WebP).

Try the example video first if you just want to see how the positioning and preview work before uploading anything of your own.

Step 2: Design your watermark

A few things to set:

Text: font size, color, background color, padding, transparency

Logo: scale it up or down while keeping the aspect ratio

Position: pick a preset corner or use the visual picker to drag it wherever

Opacity: go from subtle to fully visible depending on what the video needs

Step 3: Set the timing and output

Decide when it shows and how it's saved:

Start and end times if you only want the watermark on part of the video

Output format: MP4, WebM, or MOV

Quality: Low, Medium, or High

Frame rate: keep the original or adjust

Step 4: Preview, process, download

Once the settings look right:

Preview the watermarked video with playback controls

Download with a sensible filename

Reuse the settings for a batch of similar videos

Save the configuration as a preset for future projects

Tip: If you've got a folder of videos all needing the same watermark, set it up once, save the preset, and apply it to each file. Keeps your branding consistent without redoing the work.

Your video never leaves your device
No uploads, no cloud processing
No sign-up or personal info needed
Completely free with no limits

Wren Ashworth

"I put my logo on every client video before delivery, and this does it without firing up Premiere just for a watermark. The visual position picker is what makes it—I can drag the watermark exactly where it looks right on each video instead of guessing at coordinates."

Thiago Almeida

"Works well for adding copyright text to tutorial videos. The text customization covers more than I expected—padding, background color, all of it. Only complaint is I wish the font list were longer, but the default looks fine."

Odette Fontaine

"Does the job. I watermark stock footage before sending previews to clients and this handles the batch fine. Would be 5 stars if it remembered my preset between sessions—I always use the same settings so re-entering them is a bit tedious."

Casper Berglund

"The no-upload thing matters for me. I work on pre-release content and can't risk sending it through some random cloud tool. Everything staying local means I don't have to think about it."

Iris Chandrasekhar

"Set the watermark to appear only during the intro of my videos—first 15 seconds, then it goes away. Most free tools only let you put it on the whole thing. Being able to control the timing was the deciding factor."

Marius Hollingsworth

"I run a small production company and this has become part of our delivery workflow. Preview matches the output exactly, which I appreciate—some tools show you one thing and render another. Would recommend for anyone doing brand overlays."

Common Questions

What kinds of watermarks can I add?

Text (with your own font size, color, background, and padding) or an image logo (PNG, JPG, SVG, or WebP). Both support opacity and scale adjustments. PNGs with transparent backgrounds look best for logos since there's no visible box.

How does the visual position picker work?

It captures a frame from your video and lets you drag a box around where you want the watermark. Resize it from the corners and the watermark scales with it. What you see in the picker is what gets rendered.

Can I control when the watermark appears?

Yes. Set a start and end time and the watermark only shows during that range. Useful for intro-only branding or applying it to a specific segment instead of the whole video.

What formats are supported?

Video input and output: MP4, WebM, MOV. Logos: PNG, JPG, SVG, WebP. MP4 is the safe output if you're not sure what you need.

Is there a file size limit?

Up to 2GB per video. No strict duration limit, but longer videos take longer to process depending on your device.

Is my video private?

Yes. Everything runs locally in your browser using WebAssembly. Your video never gets uploaded anywhere. That matters for pre-release or client content.

Can I preview before processing the whole video?

Yes. The live preview shows exactly how the watermark will look over the actual video. Scrub through the timeline and adjust settings in real time before committing.

Can I save my settings for future videos?

Yes. Save your watermark configuration as a preset—text or logo, position, timing, opacity, and all. Useful when you're branding a whole batch of videos the same way.

What logo format works best?

PNG with a transparent background. It sits over the video without any box around the edges. JPG works but you'll get a visible square or rectangle behind the logo. SVG works if you need it to scale without losing sharpness.

Does watermarking hurt video quality?

You control the output quality. At High, the difference from the original is barely noticeable. Lower quality settings trade some clarity for smaller files. The watermark itself doesn't degrade the video stream.
