Frequently Asked Questions
How does Wadamark protect my privacy?
Wadamark processes everything directly inside your browser on your computer or phone. Your photos and videos never leave your device, meaning we never see, store, or upload your media to any external servers.
Is Wadamark completely free?
Yes! Wadamark is free to use with no account creation, subscriptions, or watermarks added to your exports.
What file formats and limits are supported?
Supports PNG, JPG, WebP images, and MP4/WebM videos up to 90 seconds in length (including 4K resolutions).
Why does my device fan spin up during video export?
Because rendering happens on your device rather than a remote cloud server, your processor temporarily works hard to encode high-quality video.
