Why use this
Brand your videos without firing up After Effects
AI voiceover stacks with your logo
Add narration from 14 local English voices in the same render as your watermark. Kokoro TTS runs on-server — your script never goes to ElevenLabs or OpenAI. Logo composites on top of the narrated, music-mixed frame.
AI captions — stacks with logo too
Local Whisper burns time-synced captions into frames, then your logo composites over the captioned output. Watermark, captions, voiceover, and music — all in one pass, no manual assembly.
Clean PNG composite — 4 corners
Drop a PNG with alpha and it composites cleanly — no white box, no halo. Top-left, top-right, bottom-left (default), bottom-right. 20px margin so the logo clears social-platform UI overlays. Size slider 5–40% of width.
Opacity + size — precise control
Default 85% opacity is visible without distracting. Drop to 30–50% for a "there if you look" ghost mark. Percentage-based sizing means your logo looks proportionally correct at 720p, 1080p, and 4K without any manual adjustment.
500,000 CC0 music tracks
Search Freesound's CC0 catalog and bake music in the same pass as your watermark. Music auto-loops or trims to match video duration. No attribution required — use it in ads, client work, or social posts.
Every platform, one upload
Bulk-export across TikTok, Reels, YouTube, and Instagram in one session. Every variant gets the watermark in the right spot at the right size — and the same captions, voiceover, and music baked in.
FAQ
Adding a Watermark to Video — Common Questions
What image formats can I use as a watermark?
PNG, JPG, and SVG. PNG with transparency is the cleanest choice — your logo's alpha channel is preserved through compositing. JPGs work too but will appear as a solid rectangle (the opacity slider lets you make them semi-transparent).
Where can I position the watermark?
Four corners: top-left, top-right, bottom-left (default), or bottom-right. The watermark always sits 20px from the edge so it doesn't get clipped during platform compression.
Can I control the size?
Yes — slider from 5% to 40% of the output video width. The watermark scales proportionally to maintain its aspect ratio. At 15% (default), a 1080p video gets a 162px-wide watermark; a 4K video gets 576px.
Can I make it semi-transparent?
Yes — opacity slider from 20% to 100%. Default is 85%, which is visible without dominating the frame.
Will the watermark show up clearly across all resolutions?
Yes — sizing is percentage-based on video width, so the watermark looks proportionally identical at 720p, 1080p, and 4K. Drop one logo file and bulk-export across TikTok / Reels / YouTube / Instagram and the watermark looks right on all of them.
Does this work for animations too?
Yes — same flow for HTML animation exports (Claude Design, Lottie, GSAP, CSS). Drop your animation ZIP, drop your logo, render. The watermark composites onto the rendered animation just like it would onto a video.
Can I combine watermark with captions / voiceover / outro?
Yes — all features stack. The watermark sits on top of the rendered video before captions are burned in, and the outro card appears at the very end as a separate segment. Music ducks under voiceover. All work together without conflict.
How much does it cost?
