Frequently Asked Questions

Is converting OGV to FLV free?

Yes. This OGV → FLV converter runs entirely in your browser and is completely free — no account, no credits, no watermark.

Which devices and platforms can I use to convert OGV to FLV?

Any modern device with a current web browser: Windows, macOS, Linux, Android, iPhone and iPad. There is nothing to install — the conversion happens locally.

Are my OGV files uploaded to a server?

No. Files never leave your device. The entire OGV → FLV conversion runs locally in your browser, so your data stays private.

Can I convert multiple OGV files at once?

Yes — batch conversion is supported. Add as many OGV files as you like and convert them to FLV in one pass, then download the results together.

What is the maximum file size?

There is no fixed server-side limit because the conversion happens in your browser. Practical limits depend on the available memory and CPU of your device.

Will converting OGV to FLV reduce the quality?

Because both formats use lossy compression, the FLV output will not bring back any quality that has already been lost in your OGV file. Avoid repeated re-encoding to keep the best quality.

Does FLV support transparency?

No — FLV has no alpha channel. Transparent areas of your OGV file will be filled with a solid background colour in the converted file.

How will the file size change after converting OGV to FLV?

Both formats use comparable compression, so the FLV output will be similar in size to your OGV file — typically within 10–20% of each other.
