Is my video uploaded anywhere?

No — add watermark runs entirely in your browser using the Canvas and MediaRecorder APIs. Your file never leaves your device.

What output format do I get?

Chrome and Edge export WebM; Safari exports MP4. For a specific format, re-encode with a desktop editor if needed.

Is there a file size limit?

Videos up to 500 MB are supported directly in the browser. Larger files may be slow depending on your device's memory.

Do I need to install anything to add watermark?

No installation needed — everything runs in this page using your browser's built-in video APIs.
