Operation process
Follow these steps to add watermark to video online free with a clear preview and export-ready file.
Step 1
Upload your clip
Drop an MP4, MOV, or WebM and pick a preset canvas (16:9, 9:16, 1:1) so the watermark fits social crops.
Step 2
Place your watermark
Add a transparent PNG logo or type a text watermark, then adjust position, opacity, and safe margins with live preview.
Step 3
Export and share
Render once and download a clean, watermark-protected export ready for TikTok, YouTube Shorts, Reels, or client delivery.
Principle & pipeline
The watermark engine composites your logo or text layer over the video using standard alpha blending and consistent margins, so the final export keeps clarity and alignment.
Overlay logic
The tool anchors your watermark to a chosen corner or center, scales it with the frame, and applies an alpha blend so edges stay smooth. Safe-zone markers help avoid UI elements on TikTok or YouTube Shorts.
The compositing pass respects aspect-ratio changes, keeping your watermark in the same relative spot on vertical or landscape cuts. A single render merges the overlay to prevent ghosting or repeated compression.
Quality preservation
Smart scaling keeps your watermark crisp. Transparent PNGs and vector-like text stay legible even after export or re-uploading to social platforms.
Recommended: upload a 2x logo for high-density screens, set opacity between 50–80%, and lock margins to 24–32px so the watermark remains visible after platform recompression.
