Tabelião

An area to sign with a finger, stylus or mouse, with a baseline, the signer's name, the date and export.

Tabelião · Portuguese for notary.

In short

Tabelião is an exclusive THM Componentes component for collecting signatures on terms and contracts. People sign with a finger, stylus or mouse, and the stroke thickens or thins with speed and stylus pressure. It offers undo, redo and clear, PNG and SVG export, a read-only mode and a typed name option, with labels in Brazilian Portuguese.

The catalog, this component's prompt and its sample texts are in Brazilian Portuguese. AI coding assistants apply the prompt the same way.

What it looks like

It looks like the signature line on a paper contract. On a white card, a wide area with a faint dot pattern shows an X, a baseline and, under it, the signer's name and the date and time. While empty, it shows a short hint with a pen icon. The ink is navy blue, thin on fast movements and thicker on slow ones, with smooth curves like a real pen. Above, a toggle switches between drawing and typing the name in a cursive font; the footer holds undo, clear and the PNG and SVG buttons.

You may be looking for this if you asked for something like

  • let people sign with their finger on the phone screen
  • a signature field for a consent form
  • collect a customer signature on a contract on my site
  • a box to sign with the mouse and save as an image
  • a typed cursive signature for people who cannot draw
  • sign a telehealth consent form in the browser
  • save the signature as PNG or SVG to attach to a PDF

Also known as

  • signature pad
  • signature field
  • signature canvas
  • draw signature
  • sign on screen
  • handwritten signature input

When to use

  • Consent forms for telehealth and healthcare visits
  • Contracts, proposals and work orders signed in the browser
  • Signed acceptance in sign-ups and delivery receipts
  • Displaying saved signatures in read-only mode

When to avoid

  • Documents that legally require a certificate-based digital signature, since the pad records a drawing
  • Flows where a simple acceptance checkbox is enough

How to ask your AI

Sample request
Add a signature pad to the consent form: variable-width strokes for finger, stylus and mouse, undo and clear, a baseline with name and date, PNG and SVG export, a typed name option and my brand colors.

With THM Componentes, you paste the full prompt from the catalog, which already includes this component's source code, and the AI reproduces this exact effect instead of improvising.

Questions about Tabelião

Does Tabelião work with a finger on phones?

Yes. Tabelião uses Pointer Events and blocks scrolling over the signing area, so the finger draws without dragging the page. With a stylus, it reads real pressure and ignores a palm resting on the screen. On small screens, the undo and clear buttons shrink to icons.

How do I save the signature from Tabelião?

In three ways. Tabelião downloads PNG or SVG from its buttons, exposes toPNG and toSVG methods with optional trimming, scale, background and baseline, and provides the normalized strokes through v-model, which you can store and display again later, including in read-only mode.

Does Tabelião offer an option for people who cannot draw?

Yes. Tabelião has a typing mode: people type their name and choose one of three cursive styles from the system fonts. The signature area takes keyboard focus, describes its content to screen readers and supports Ctrl+Z to undo.
