Sharing a Form

The public link

Every form is reachable at one address, built from the form's own ID:

https://fillio.so/r/YOUR_FORM_ID

There is no publish step. The link works from the moment the form is first saved and keeps working through every later edit. The address never changes, so anything you have already printed or posted stays correct.

Where to copy it

Open the form and go to the Share tab: the address sits in the Share Link card with a Copy link button beside it. The same action is in the editor too: press Share in the header and copy the link without leaving the canvas.

What the respondent needs

Nothing. Answering a form needs no Fillio account and no sign-in, and the page opens straight into the first question, unless you have put a password, a schedule or a response limit on the form.

QR code

In the Share tab, next to Copy link, press Download QR. The editor's Share menu offers the same download.

You get a PNG called form-qr-code.png, 512 pixels square, plain black on white with a quiet margin around it. That is large enough for a poster; keep it black on white when you print, because a reader needs the contrast.

The code encodes the public link and nothing else, so it survives every change you make to the form. Print it once and keep editing the questions underneath. But remember that if you delete the form, or close it with a schedule, the printed code leads to the closed screen.

The preview card

When your link is pasted into a message, a post or a chat, the app rendering it asks Fillio for a title, a sentence and an image. Share tab → Social Sharing sets all three, and the card beside the fields updates as you type. Everything saves on its own.

If you leave them empty

The title falls back to the form's own title, or to "Untitled Form" if it has none. The description falls back to Fillio's own line, "Made with Fillio, the simplest way to create forms for free." The image falls back to Fillio's default artwork, which means an unset card advertises Fillio rather than you. One sentence and one picture are worth the minute they take.

About the image

Any image file up to 10 MB is accepted. Larger pictures are scaled down in your own browser to fit within 1200 × 630 before they are uploaded, so the upload stays quick and the file stays small. The card is declared at 1200 × 630, so a picture already in that shape fills it exactly; one of a different shape is scaled to fit inside those bounds and each app then frames it its own way.

Why the old card still shows

Messaging apps and social networks cache a preview the first time a link is seen and reuse it for a long while. Set the card before you share the link the first time. If you change it afterwards, use that platform's own link-debugging tool to force a refresh. Fillio serves the new card immediately, but the app in front of it may not ask again.

Putting the form on your own site

The second half of the Share tab builds embed code instead of a link: an inline frame, a popup triggered by your own button, or a page the form takes over completely. That has a page of its own.
