Frequently Asked Questions

Is it really free?

Yes! VidFlip is completely free with no hidden charges, watermarks, or signup required.

Are my files safe?

Your files never leave your device. Everything is processed locally in your browser using WebCodecs. No data is ever uploaded to any server.

What's the maximum file size?

There's no artificial limit. It depends on your browser's available memory. Most browsers handle files up to ~2GB.

Which browsers are supported?

Chrome 94+, Edge 94+, and other Chromium-based browsers with WebCodecs support. Firefox and Safari have partial support.

How does it work without a server?

VidFlip uses WebCodecs — a browser API that gives JavaScript direct access to your device's hardware video encoders and decoders. Container formats are parsed and written from scratch in pure JavaScript.
