# facebook.media.mime_allowed

> Facebook Pages accept jpeg/png images and mp4/mov video.

## What it checks

For images: `mimeType ∈ { image/jpeg, image/png }`.
For videos: `mimeType ∈ { video/mp4, video/quicktime }`.

WebP, HEIC, GIF on the photo path will fail upstream with opaque `code 100`.

## Remediation

Re-encode to JPEG or PNG for images; mp4 (H.264 + AAC) for video.
