2Type your watermark text and set its position and opacity.
3Export and download the watermarked video.

Brand or protect

Add your handle, name or @username to discourage reposts and build recognition.

Position and opacity

Place the text where you want and dial in how subtle or bold it is.

Private and free

Only your watermark is added — we add nothing — and the video never leaves your device.

Stamp your @handle on Reels

Before posting clips to Instagram, TikTok or YouTube, drop the video here and stamp your @handle in a corner so reposters carry your name with them. Type your username, tuck it bottom-right where captions rarely cover it, and lower the opacity so it brands without distracting. The text burns into the MP4 permanently, surviving downloads and re-shares.

Mark client drafts as preview

Sending an unfinished edit to a client for approval? Stamp a bold PREVIEW or DRAFT across the center at higher opacity so the cut can't be passed off or published before you're paid. Center placement and a strong setting make the text impossible to crop out cleanly, then you hand over a clearly-marked review copy and keep the clean master to yourself.

Add a copyright line to footage

Protect original footage by stamping a copyright notice, like your studio name and the year, into the frame before you share or license it. Place the text top-left or bottom-left so it stays clear of the action, keep the opacity subtle so it reads without dominating, and export an MP4 that carries your attribution everywhere the file travels.
