Media limits and processing
Two sets of limits apply to every post: Postbean’s upload caps, which are validated before the file leaves your browser, and each network’s own rules, which apply at publish time.
Postbean’s upload caps
Section titled “Postbean’s upload caps”| Type | Formats | Maximum |
|---|---|---|
| Image | JPG, PNG, WebP | 8 MB per file |
| Video | MP4, MOV | 100 MB per file |
| Media per post | — | 35 items |
Anything outside these is rejected in the composer, with a message saying which limit it hit, rather than failing later at publish time.
