🪪Share card (social preview image)

Control the preview image that appears when your Dapta Form link is shared in chat or on social media: a 1200×630 card generated automatically from your design, or your own image URL.

A form is shared as a link far more often than it is found by search. When someone pastes your public link into WhatsApp, Slack, LinkedIn, X or an email client, those apps show a preview card: a title, a short description and an image. Dapta Forms builds that image for you, at the standard 1200×630 size, straight from the colors, typeface, logo and cover copy of your form. Change a color in Design and the card changes with it. Nothing to upload.

If you already have a designed asset, paste its URL and it is used instead.

Step 1: Open your form, click Design in the toolbar and scroll to the Share card section. The small mock-up at the top shows how the link reads (your account code and the title), so you can check the wording at a glance.

Step 2: To use your own image, paste a public link into Share image URL. Ideal size is 1200×630 pixels. Leave the field empty to keep the generated card.

The Share card section in the Design panel: a mini link preview, the Share image URL field with the hint Ideal size 1200×630, and the note that an empty field generates the card from the colors and logo above
The Share card section. Paste an image URL to override the generated card, or leave it empty.

Step 3: Click Publish. To see the generated image, open your public link and add /opengraph-image to the end, for example https://forms.dapta.ai/k7m2xq/alex/product-fit-quiz/opengraph-image.

The generated 1200 by 630 share card: dark background from the form theme, Dapta Forms mark, the banner text as a pill, the cover headline and subheadline, a progress bar, the question count, the host name and a Start button in the accent color

What the generated card shows

The card is laid out from your form's own design, so it looks like the page it opens.

Part of the card
Where it comes from

Background and colors

The Theme, Colors and Background style of the form (including a background image, dimmed so the text stays readable).

Typeface, corners and button style

Typography and Shape and controls in the Design panel.

Logo

Form logo URL (or Cover logo URL) from the Layout section. With no logo, the card shows the Dapta Forms mark.

Pill above the headline

The Banner text of the cover, if any.

Headline

The cover Headline. If empty, the public Form title; if that is empty too, the form's internal name.

Second line

The cover Subheadline. If empty, the text of the first question.

Footer

The number of questions, the host name (for example forms.dapta.ai) and a Start button in the accent color. The button always reads Start, regardless of your custom Start button text.

The title and description of the link preview (the text next to the image) come from the same places: the public Form title (falling back to the form name), and the cover Subheadline (falling back to "Fill out {form name} online.").

Good to know

  • Updates take a few minutes. The generated card is refreshed about every 10 minutes, so a change in Design may take that long to show up in a new share. Social platforms keep their own copy for longer; most of them offer a "re-scrape" or "refresh preview" tool if you need the new card immediately.

  • Your own image wins completely. When Share image URL is set, the generated card is not used at all. Use a public HTTPS link to a PNG or JPG; the platforms ignore images they cannot download.

  • Publish first. The card is built from the published version of the form, so design changes you have not published yet do not appear on it.
