Rich text and media

The rich-text editor

Question text (and Content questions' Visual tab) use a rich-text editor with the usual formatting, bold, italics, lists, links, and images. The editor follows your light or dark theme.

Inserting images

The toolbar's image button opens the asset picker over your Assets library. Pick an existing image or upload right there, the image lands at your cursor. Inserted images keep a stable reference to the asset, so the platform always knows which surveys use which files, the Assets page can filter by survey, and deleting an in-use asset warns you with the list of affected surveys.

Large images are displayed scaled to fit the question area on every device, participants on phones see them sized to the screen.

Embedding video and other media

Content questions accept arbitrary HTML, paste an embed snippet (for example a video iframe) into the HTML tab. Embedded media is also scaled to fit its container on small screens.

Public files only

Anything embedded in a survey page must be a public asset, participants' browsers fetch it directly. Private assets are for confidential spreadsheets and similar researcher-side files, they have no public URL and cannot be embedded. See Visibility and deletion.
