Fix Zoom's "failed to convert" recording error.

Why Zoom throws "failed to convert"

Zoom records your meeting as raw audio and video and only assembles the final MP4 when the meeting finishes. If that final conversion is interrupted — a crash, a forced shutdown, a full disk, or the meeting dropping mid-recording — Zoom can't complete the job and shows "failed to convert," or leaves a zoom0.mp4 that's stuck at 0% or won't open.

The important thing to understand: this error is about the conversion step, not necessarily about your footage being destroyed. The raw recording is usually still on disk. That's why re-running Zoom's converter (double-click the recording in the Zoom app) is worth trying first — when the interruption was minor, it often finishes on the second attempt, for free.

When Zoom's converter genuinely can't finish, it's because the raw recording was truncated — the tail of the file it expects simply isn't there, so its all-or-nothing converter gives up. FileFix is built for exactly that: we don't need a perfect file. We read the footage that was written, rebuild a valid structure around it, and produce an MP4 that plays.

You'll see precisely how much we recovered in a free, watermarked preview before paying. And if the recording turns out to be empty — Zoom failed before capturing anything — we'll tell you honestly and there's no charge.
