Is this really 100% free?

Yes! LogoOnVideo is completely free with no hidden fees, no premium tiers, and no watermarks on your output. Ever.

Do you store my videos?

Absolutely not. Your videos are processed entirely in your browser using WebAssembly technology. We never see, upload, or store your content.

What video formats are supported?

We support MP4, WebM, and MOV files. The output is always a high-quality MP4 file.

Is there a file size limit?

Since processing happens in your browser, the limit depends on your device's memory. Most modern devices can handle videos up to 500MB easily.
