    Frequently asked questions

    Does converting reduce quality?

    With “Best quality” the video is copied without re-encoding whenever the codec already fits MP4 (for example H.264 in a MOV) — that is instant and lossless. Otherwise it is re-encoded at high quality.

    Can I convert iPhone videos (HEVC)?

    Yes, if your device can decode HEVC — Macs, iPhones and most Windows PCs with recent graphics can. Chrome on older PCs may not.

    Are my files uploaded?

    No. FileCrafty processes video and audio inside your browser using your device’s own media engine, so nothing is uploaded — it even works offline once the page has loaded.

    Which browsers are supported?

    Recent Chrome, Edge and Safari work best because they can encode MP4 (H.264 + AAC). Firefox works for most files. On phones, very long or 4K videos may be too big for the available memory.

    Is there a file size limit?

    There is no fixed limit, but everything happens in your device’s memory. On a computer files up to 1–2 GB usually work; on phones keep videos shorter.
