FAQ

Questions? Answered.

Everything you need to know.

Are my files really private?

File contents are processed in your browser rather than uploaded for conversion. The website uses analytics and advertising, which make third-party requests. Conversion events do not include filenames or file contents. See our privacy policy for website tracking details.

What's the maximum file size?

We do not impose a daily quota or a fixed upload-size cap. Browser memory, file complexity and codec support limit what can be processed. Try smaller files if your device runs out of memory.

How is this free?

flux-convert is supported by minimal, non-intrusive ads. Since all processing happens client-side, there are minimal server costs — just serving the static web app.

Which formats are supported?

We currently support 75 file formats and 226 conversion pairs across 9 categories including images, documents, audio, video, data, fonts, and more.

Can I convert multiple files at once?

You can convert one file to multiple output formats simultaneously. Download individually or as a ZIP.
