Why use this video watermark tool?

Logo or text, your choice

Pick a PNG/JPG/WebP logo or type a text watermark in the font, size, and colour you want. Same editor controls as our image and PDF watermark tools, so it feels familiar from the first click.

Drop it exactly where you want

Use the 9-point anchor grid for the usual corners, or drag the watermark around the preview to land it on a precise spot. Margin, rotation, and opacity sliders are right there for the fine-tuning.

Show it only when it matters

Keep the watermark on for the whole clip, restrict it to a single time window, or pulse it on every N seconds. Fade-in and fade-out sliders smooth out the edges so the appearance never feels abrupt.

Live preview, frame-accurate

Adjust opacity, drag the position, change the fade — and see the result on the actual video as you scrub. No "render to preview" loop: what you see is what the encoded MP4 will look like.

Your video stays on your device

All the encoding runs in your browser via FFmpeg compiled to WebAssembly. The video file never leaves your laptop, your phone, or your network — not for upload, not for processing, not for download.

Tile across the frame

Want the watermark stamped repeatedly across every frame to make screen-recording theft much harder? Flip the tile switch and the watermark replicates in a grid you control with margin and opacity.

Why people watermark videos

A coaching video that needed to stop walking off

You're a fitness coach who films short technique demos and posts them on social. Last month you spotted one of your own clips on a competitor's feed — re-uploaded, no credit, claiming the form correction as their own. You wanted a watermark on every video going forward, but the desktop editor you used to own is gone with the laptop you replaced, and the free online tools either capped the upload at 100 MB or wanted a subscription before they'd let you download.

You drop today's twenty-second clip onto the page, type your handle as the watermark, and drag it to the bottom-right of the frame. You crank the opacity down to forty percent so it doesn't fight the video, set a half-second fade-in so it doesn't pop in jarringly, and watch the preview as you scrub the timeline. It looks right.

You hit "Watermark video", wait under a minute for the encode, and download the new MP4. By tonight it's posted, with your handle quietly visible in every second. The clip that wanders off this time wanders off carrying your name with it.

A wedding rough cut you want to share without losing it

You're a wedding videographer sending a rough cut to the couple before the final delivery. You want them to be able to share a draft with parents and bridesmaids — but not pass it on as the finished thing, and definitely not have it end up reposted somewhere with your work uncredited. A "DRAFT — do not share" overlay would do the job, but you want it tasteful, not screaming across the whole frame.

You drop the rough cut onto the page, switch the watermark type to text, and write "© Your Studio · Draft". You set it to tile mode at low opacity, with a slight rotation, so the entire frame is gently stamped — visible enough to discourage cropping, faint enough that the couple can still see their own faces clearly.

You send the watermarked MP4 to the couple in the morning. They love it, share the draft with the wedding party, and nobody mistakes it for the polished version. When the final delivery goes out, it's clean — and the rough cut, even if it pops up somewhere it shouldn't, can't pretend not to be a draft.

A tutorial that earns the brand back

You're an instructional designer who records short Loom-style videos for an internal training platform. The platform pulls those clips into a learner-facing portal, and IT has been asking you to brand them so when learners screen-record their progress (which they do, often) the brand still travels with the file.

You upload one of the longer modules — about eight minutes. You set the watermark to your company logo, anchor it to the top-left, and configure the timing to "Repeat every": show for five seconds every thirty seconds, with a half-second fade. That way it doesn't sit in the corner the whole time covering the demo — but it appears often enough that any snippet a learner shares carries the brand with it.

A few weeks later one of those snippets shows up in a partner's onboarding deck — properly attributed because the watermark told them where it came from. IT stops asking. The learners stop noticing. You move on to the next module.
