Pulsa el icono azul para descargar el documento.

Pulsa here means press or tap.

Grammatically, it is the affirmative tú imperative of pulsar:

• pulsar = to press / to tap
• pulsa = press! / tap!

So the sentence is giving a direct instruction to you.

A few related forms:

• tú: pulsa
• usted: pulse
• negative tú: no pulses

In another context, pulsa could also mean he/she presses, but here it is clearly an instruction.

All of these can be possible, but they are used a bit differently.

• pulsa is very common in instructions, especially in Spain, for press/tap
• presiona also means press, but can sound slightly more physical
• haz clic means click, so it is especially natural for a mouse/computer context

So:

• on a phone or touchscreen, pulsa is very natural
• on a computer, haz clic en el icono azul might also be very common

In Spain, pulsa is a very normal choice in interface language and instructions.

Because pulsar can take a direct object in Spanish.

So Spanish says:

• Pulsa el icono azul literally: Press the blue icon

English often says click on the icon or tap the icon, but Spanish does not need a preposition here.

Compare:

• Pulsa el botón = Press the button
• Pulsa la tecla Enter = Press the Enter key

If you use hacer clic, then you normally do need en:

• Haz clic en el icono azul

Yes. Icono is a masculine noun, so it takes el:

• el icono
• el icono azul

That is simply the gender of the noun in Spanish. It does not depend on the fact that the thing itself is an image or symbol.

Plural:

• los iconos

Because azul is an adjective that usually does not change for masculine/feminine in the singular.

So you get:

• el icono azul
• la carpeta azul

And in the plural:

• los iconos azules
• las carpetas azules

So in this sentence, azul matches icono in meaning, but it does not need a special masculine singular ending.

Because in Spanish, most descriptive adjectives normally come after the noun.

So:

• el icono azul = the blue icon
• el documento nuevo = the new document

This is the normal word order for a basic description.

Sometimes adjectives can go before the noun, but that often changes the tone or meaning slightly. In this sentence, el icono azul is the standard and expected order.

Para + infinitive is a very common way to express purpose in Spanish.

So:

• para descargar el documento = to download the document / in order to download the document

It answers the question why?

• Pulsa el icono azul — why?
• Para descargar el documento

More examples:

• Abre la aplicación para ver tus mensajes = Open the app to see your messages
• Pulsa aquí para continuar = Press here to continue

Because after para, Spanish normally uses the infinitive when the subject stays general or understood.

So:

• Pulsa el icono azul para descargar el documento literally: Press the blue icon to download the document

The infinitive descargar works like English to download.

You would use a conjugated form after para que instead:

• Pulsa el icono azul para que se descargue el documento This is grammatically possible, but much less direct and less natural for a simple instruction.

Spanish often uses the definite article where English might or might not use one.

Here, el documento means the document, referring to the specific document the user is expected to download.

In interface or instruction language, Spanish usually includes the article:

• abre el archivo
• cierra la ventana
• descarga el documento

Leaving out el would sound unnatural in this sentence.

It can cover all three depending on context, which is why it is so useful in instructions.

In practice:

• on a touchscreen, it often feels like tap
• on a button or key, it feels like press
• in some digital instructions, it may even function like click

So the exact English translation depends on the device and situation, even though the Spanish stays the same.

Yes. If you want to address someone formally, you would usually use usted:

• Pulse el icono azul para descargar el documento.

That is the formal imperative of pulsar.

So:

• Pulsa = informal singular (tú)
• Pulse = formal singular (usted)

In Spain, many apps and websites use the informal style because it sounds direct and friendly.

Yes, it sounds very natural in Spain.

A few reasons:

• pulsa is common in instructions in Spain
• the tú imperative is widely used in friendly interface language
• the overall style is concise and typical of software or website instructions

In other Spanish-speaking regions, you may also see alternatives like:

• presiona
• oprime
• haz clic en
• toque / toca in some contexts

But the original sentence is perfectly standard and very natural for Spain.

In Spain, the plural informal imperative would use vosotros:

• Pulsad el icono azul para descargar el documento.

So:

• tú: Pulsa
• vosotros: Pulsad
• usted: Pulse
• ustedes: Pulsen

This is useful because Spain commonly distinguishes vosotros from ustedes, while many other regions use ustedes for all plural you forms.
