Are my AVIF files uploaded anywhere?

No. This conversion runs entirely inside your browser, so the file never leaves your device. You can confirm it yourself: open the network tab of your browser's developer tools and watch that nothing is sent while the file converts.

Is converting AVIF to BMP free?

Yes, without a limit on how many files you convert and with no watermark on the result. Files up to 100 MB are covered by the free plan.

Does converting AVIF to BMP lose quality?

No. BMP stores the same content without discarding anything, so the result is identical in quality to the original. Transparency is not supported by the target format and is filled with the background colour.

Do I need to install anything to open BMP files?

No installation is needed for the conversion itself — it runs in the browser you already have. Opening the BMP afterwards needs whatever software normally handles Windows Bitmap on your device.
