Why You Must Watermark Your Media

빠른 답변: Watermarking your original videos and photos is the best defense against intellectual property theft and unauthorized resharing.

In the age of viral social media, original content is frequently downloaded and reposted without attribution. By embedding your brand's logo or a custom watermark directly into your video frames or image pixels, you ensure that your authorship remains attached to the media no matter where it spreads across the internet.

Absolute Privacy via WebAssembly

빠른 답변: Most online watermarking tools require you to upload your videos to their servers. We use WebAssembly (FFmpeg) to process your media entirely on your own device.

If you are working with unreleased campaign videos, private family photos, or corporate assets, uploading them to a 'free' cloud service exposes you to significant privacy risks. Utiliome solves this by executing the complex video compositing algorithms directly inside your web browser. Your data remains strictly local and completely secure.
