Add Watermark to Video

Protect your creative work and brand every clip before it leaves your hands. Add a text watermark with a custom message, font size, and opacity — or overlay a PNG logo in any corner. Position it precisely, set transparency, and export an MP4 that carries your identity no matter where it gets shared.

The watermark tool runs entirely in your browser. Client previews, unreleased footage, and proprietary training videos are never uploaded to a third-party server. Mark the draft, share it, and strip or change the watermark when the final review is approved.

How to watermark a video in the browser

1

Upload your video

Drop the file onto the upload area or browse. MP4, MOV, and WebM all work. Wait for FFmpeg to initialise if this is your first visit.

2

Choose text or image watermark

Type your brand name, social handle, or copyright line for a text mark. Upload a transparent PNG logo for an image mark.

3

Set position and size

Place the watermark in a corner or centre. Adjust font size or logo scale so it is visible but does not obstruct the main content.

4

Set opacity

Lower opacity (30–60%) gives a subtle mark that does not distract from the footage. Full opacity is best for draft previews you want to clearly identify as proofs.

5

Export the branded MP4

FFmpeg composites the overlay during the export pass. Download the file and share it — your mark travels with every copy.

Common use cases

  • Protecting stock footage and licensed content

    Stock creators add a semi-transparent logo so buyers can preview footage before licensing, but cannot use the unwatermarked clip without purchasing.

  • Client draft delivery

    Video producers add 'DRAFT — NOT FOR DISTRIBUTION' text marks before sending review copies, ensuring clients understand the file is not final.

  • YouTube and social channel branding

    Creators place a channel logo in a corner so the brand stays visible when clips are reposted, shared on TikTok, or embedded on other sites.

  • Course and tutorial attribution

    Online educators watermark lesson recordings with the platform or instructor name so students and platforms know the source.

  • Event and conference footage

    Event videographers add sponsor logos or event branding before distributing recap videos to organisers and attendees.

Best practices

  • Place the watermark in a corner that overlaps the background, not a face or key action that viewers need to read.
  • Use 30–50% opacity for brand logos on polished content; go to 70–100% for draft proofs where visibility is the point.
  • Transparent PNG logos with soft edges look more professional than opaque rectangles.
  • Keep the mark small enough that it does not distract — roughly 8–12% of frame width is standard for corner logos.
  • Export at the same resolution and bitrate as the source to avoid quality degradation from re-encoding.
  • If you regularly deliver draft watermarks, keep a consistent text template so clients immediately recognise your workflow.

Formats & compatibility

Accepts MP4, MOV, and WebM input. For image marks, upload a transparent PNG — JPEG backgrounds become opaque boxes over the video. Output is MP4 (H.264). Watermark compositing requires full re-encoding; file size may change compared to a stream-copy trim.

Frequently asked questions

Yes. Upload a transparent PNG logo and the tool will overlay it on the video at the position and size you set.
Compositing requires a re-encode. Using a reasonable CRF/bitrate setting keeps quality high; avoid repeatedly watermarking the same file.
You can choose corners and centre positions. For pixel-perfect placement, a desktop NLE gives more control, but preset corner positions cover most use cases.
Use the original un-watermarked source file. There is no non-destructive removal from an exported clip.
30–50% for final distribution; 70–100% for drafts where full visibility is needed to identify the file as a proof.
No. The overlay happens entirely in your browser — your video never leaves your device.
Yes, though processing time increases with resolution. Ensure the browser has enough RAM for your file size.
Yes. The watermark is baked into pixels during export, so it persists through any subsequent compression or re-upload.
