Proton

The proton icon represents Proton, a secure email service that provides end-to-end encryption for emails. ProtonMail is a popular choice for individuals and organizations seeking secure communication.

The proton icon is often used in email clients, messaging apps, and secure communication platforms. It may appear in ProtonMail's user interface, website, or promotional materials.

From a UX perspective, the proton icon communicates the idea of security, trust, and confidentiality. It helps users understand that their emails and communication are protected from unauthorized access.

Proton is one of 3,632 icons in Simple Icons, made by Simple Icons Collaborators and released under CC0 1.0. It is drawn on a 24 × 24 grid.

Sign in (it's free), then open Get icon, Install with shadcn CLI, and pick your package manager to copy the command. It adds ProtonIcon to components/icons/simple-icons-proton.tsx: one file, a size prop (24 by default) and every SVG prop, with no icon package.

Copy it as React (from Get icon, or the Code section): a typed ProtonIcon component you paste into your project, with no package to install. Only the icons you import reach your bundle. It works in Next.js and any React app.

Open Get icon, then Copy as code, and pick Vue, Svelte, Angular, Solid or Preact; the Code section shows each one too. Every version is one self-contained component with the SVG inside, and SVG and data URL copies are there for plain HTML and CSS.

With Pro, the shadcn.io MCP server lets Claude Code, Cursor or any MCP client find the Proton icon, or any of 3,632 Simple Icons icons, and install it from a prompt.

It's drawn in currentColor, so it takes the text color wherever you use it: a class like text-primary recolors it. To bake a color in, set one in Customize before you copy.

Set width and height on the component, or a class like size-6. It's drawn on a 24 × 24 grid, so it stays sharp at any size. Customize also sets the size it exports at, its padding and rotation.

Yes. It follows the text color, so with text-foreground (or any theme token) it changes with your light and dark themes. The icon is a vector, so it needs no separate dark asset.

Next to a visible label it's decoration: add aria-hidden="true" so screen readers skip it. Standing alone, as in an icon button, give the button a name instead, like aria-label="Proton", so screen readers say what it does.

Yes. ProtonIcon passes every SVG prop to the svg element, so <ProtonIcon aria-hidden="true" /> works, and so do role="img" with aria-label, or a title child, when it carries meaning on its own.

Yes. Open Get icon, then Download file: SVG for code or design tools like Figma; PNG, WebP or JPEG at 512px; or an ICO favicon with 16, 32 and 48px inside. Each one uses what you set in Customize.

CC0 1.0 puts the icons in the public domain: use them anywhere, with no conditions. The full terms are in the license, linked on this page.

No. CC0 1.0 gives the icons to the public domain, so no credit and no notice is required. Icons installed with the shadcn CLI still start with a comment naming Simple Icons, Simple Icons Collaborators and the license.

Yes. Copying and downloading it is free, and the shadcn CLI install only needs a free account.
