About adding a watermark to video

Vidxt lets you stamp a logo or text watermark onto a video so it stays visible wherever the clip is shared, downloaded or re-uploaded. The watermark is rendered into the final file rather than overlaid by a player.

You can position the mark in any corner or in the centre, set its size and opacity, and decide whether it stays on the full clip or only on a chosen time range. Both image watermarks (PNG with transparency works best) and plain text are supported.

Who this is for

  • Creators protecting tutorials, art process videos or course previews from being re-uploaded without credit on other platforms.
  • Photographers and videographers sending preview cuts to clients with a visible mark before payment, replaced by a clean export on delivery.
  • Brands ensuring every short-form video that goes out on social channels carries a consistent logo in the same position and size.
  • Event organisers and trainers branding recorded sessions so that downstream clips and highlight reels still point back to the original source.

How to add a watermark

  1. 1Upload the video you want to mark, then add either a PNG/JPG image or a line of text. Transparent PNG logos give the cleanest result on busy footage.
  2. 2Drag the watermark on the preview to position it, then adjust size and opacity. Lower opacity is less intrusive, but should still be readable on bright and dark backgrounds.
  3. 3Render the video. The output is a new MP4 with the watermark baked in. The original file on your device is not modified, so you can re-render with different settings any time.

Supported video and watermark formats

Source video can be MP4, MOV, AVI, MKV, WebM or FLV, up to 2 GB on desktop and 500 MB on mobile. Watermarks accept PNG and JPG images, with transparent PNG recommended for logos, or plain text styled with font, size and colour.

Rendering stays on your device

FFmpeg WebAssembly handles both the watermark overlay and the final encoding in the browser. Your video, your logo and the rendered output never leave the device, which keeps internal review cuts and unreleased material out of any cloud storage.

Frequently asked questions

Will adding a watermark reduce video quality?

Re-encoding always involves some loss, but the tool uses a high-quality H.264 setting by default, so the difference from the original is usually invisible at normal viewing sizes. You can raise the bitrate if you want to be conservative.

Can the watermark appear only during part of the video?

Yes. You can set a start and end time for the overlay, which is useful for intros, sponsor segments or sample previews where the mark should appear only on a teaser section rather than the entire clip.

Does it support animated or moving watermarks?

Static image and text watermarks are supported in the current version. Position, size and opacity are fixed for the duration of the overlay window. Animated GIF or video watermarks are not yet available in the browser tool.

Is there a free tier?

Yes. Casual use, including standard 1080p exports with image or text watermarks, is free. Power users who render long videos at higher resolutions frequently can move to a paid plan for higher limits and priority encoding.
