Media & assets

Blok has a built-in Assets panel and picker for managing images, videos, and other media referenced by asset fields.

The Assets panel

Open the Assets tab on the right rail. It shows all known assets (those your developers have wired up). Typical flows:

• Browse — scroll the library, preview thumbnails.
• Search — filter by name or metadata.
• Insert — click an asset to copy its URL, or drag it into an asset field.

The Asset picker

When an Edit field is of type asset, you’ll see a picker:

• A URL input with preview.
• An alt text field, for accessibility and SEO.
• A Browse library button that opens the Assets modal.

Set alt text for every image — it shows up in screen readers, image search, and the SEO panel’s readiness score.

URL-only assets

If your app hasn’t wired up an asset library, the Asset field still accepts any URL you paste in. Use an external CDN, S3 presigned URL, or your existing media storage.

Where assets are saved

Assets are references — the actual bytes live wherever your developer configured. Blok stores only the URL (and alt text) in the document. Publishing the document publishes the same URL; it doesn’t re-upload anything.
