Who we are
Flash Visualizer is built and operated by Charlestowne Marketing, an independent SEO and web design studio in Charleston, South Carolina. The visualizer started as an internal experiment: we wanted a music video tool that actually listens to the track instead of decorating it, and nothing free did that without a watermark, an account wall or an upload step. So we built it and put it online for anyone to use.
What we promise
The whole app runs in your browser. Your audio and images are decoded and rendered on your own machine and are never sent to us or anyone else; there is no account system because there is nothing for an account to hold. Every feature is free, exports carry no watermark, and that is not a trial state we plan to walk back.
The one thing we ask in return: this tool makes strobe content. Label your uploads with a flash warning and keep photosensitive viewers in mind. We keep a warning on every page of this site for the same reason.
How to reach us
Questions, bug reports or a feature you wish existed: contact us through charlestowne.marketing/contact. Feature requests genuinely shape the tool; most of what is in the app today was added because someone using it asked.
