# Media library

> Everything you have uploaded, in one searchable place

**Where:** the Media section, or **Insert Media** inside the composer

Every file you upload or generate lands in the media library, so you can reuse
it without hunting for the original.

## What is in it

* Files you uploaded from the composer or from this page.
* Images and video generated by AI, see
  [AI generation](/general/composer/ai-and-imports).
* Media imported from a connected third-party service.

## Working with it

| Action            | How                                           |
| ----------------- | --------------------------------------------- |
| **Upload**        | The upload button, or drag files in           |
| **Search**        | By file name                                  |
| **Preview**       | Maximise any item                             |
| **Delete**        | Per item                                      |
| **Use in a post** | Open the library from the composer and select |

Results are paginated rather than infinite scrolling, so a large library stays
usable.

## Limits

Images are capped at 10 MB each and video at 1 GB, and the accepted types are
JPEG, PNG, GIF, WebP, AVIF, BMP, TIFF and MP4. Postiz reads the real type from
the file contents, so renaming the extension does not help.

## Where library media is used

Besides posts, the library is the picker for:

* A channel's bot picture, see [Manage a channel](/general/channels/manage).
* An OAuth app's icon, see [Developer settings](/general/settings/developers).
* Attachments in the [AI agent](/general/agents) chat.

## Deleting

Deleting removes the file from the library. Posts that already published are
unaffected, since the platform holds its own copy. Scheduled posts still
referencing a deleted file will fail at publish time, so check before removing
anything recent.
