Frequently Asked Questions (FAQs)
Q: What image formats can I upload for video logo watermarks?
A: Transparent PNG files (.png) are ideal for logos and branding stamps because transparent backgrounds blend seamlessly over video frames. JPG, WebP, and SVG images are also supported.
Q: Can I adjust the opacity and transparency of the watermark?
A: Yes! Use the opacity slider to adjust watermark transparency from subtle 20% translucency (ideal for subtle copyright protection) to 100% solid opacity.
Q: Are my confidential video files uploaded to remote servers?
A: No! All watermark compositing and video rendering execute 100% locally in your web browser memory. Your personal recordings and proprietary logos never leave your computer or phone.
Q: Where should I position my watermark on the video?
A: Bottom-right and top-right corners are industry standards for social media and broadcast video, keeping core video action unobstructed while securing branding.
Q: Does OnlineConverter add any of its own branding or watermarks?
A: No! All exported videos contain strictly your custom watermark with zero third-party logo stamps or branding restrictions.
