How to translate Google Slides™ to Spanish

Who this is for

Spanish is the second most spoken language in the US, so it is a common target for presentations. The typical cases:

• Schools and teachers — back-to-school night, class expectations, field-trip and conference information for Spanish-speaking families, and lesson slides for English language learners (ELL) who are still building their English.
• Bilingual meetings and trainings — one deck that works for English and Spanish speakers in the same room.
• Teams sending a deck to a Spanish-speaking client or office.

Step by step with an add-on

These steps use our add-on, Translate Slides with AI; other add-ons work in a similar way (see the comparison).

1. Make a copy: File → Make a copy → Entire presentation, and name it, for example, “Open house — Español”. The add-on rewrites the file it runs on, so keep the English original.
2. Install the add-on from the Google Workspace™ Marketplace.
3. In the copy, choose Extensions → Translate Slides with AI → Open translator.
4. Leave From on Auto-detect and set To to Spanish.
5. Tick Also translate speaker notes if you present from notes.
6. Optional but worth it: in Prompt / context, write who the audience is, for example “Parents of elementary students in the US. Latin American Spanish. Address parents as usted. Keep the school’s name in English.”
7. Click Translate deck. Titles, body text, tables, grouped shapes and (if ticked) notes are translated in place, with bold, colours and links kept on the right words.
8. Review the result in View → Grid view and fix anything that overflows (see the tips below).

The free plan covers 100 translated slides per calendar month, which is plenty for a typical school or meeting deck. Text inside pictures — a flyer pasted in as an image, a chart image — is not translated, so retype that text in a text box if it matters.

The free way with Google Translate

No add-on needed:

• Copy-paste: copy each text box into translate.google.com (English → Spanish) and paste the result back. Fine for a handful of slides.
• Whole file: download the deck as File → Download → Microsoft PowerPoint (.pptx), upload it on Google Translate’s Documents tab (files up to 10 MB, per Google’s help page), click Download translation, and open the translated file in Google Slides again. Check fonts and layout after the round trip.

Both ways, with their pros and cons, are in How to translate Google Slides (3 ways).

Teachers may also come across Slides to Spanish+ by AliceKeeler LLC, a free add-on built for classrooms. Its Marketplace listing (checked 16 October 2026) says it creates a new presentation for each selected language using Google Translate, that formatting is mostly retained but mixed styling inside one text box is not, and that it does not support slides with non-default dimensions.

Making a bilingual English–Spanish deck

For an audience that mixes English and Spanish speakers, there are three common layouts:

Two decks, shared side by side

Translate a full copy and share both links, or present from one and send the other. Simplest, and nothing gets crowded.

English slide, then the Spanish slide

1. Select a slide in the left panel and press Ctrl+D (⌘D on Mac) to duplicate it.
2. Click the duplicate so it is the current slide.
3. In the add-on, tick Translate only the current slide, choose Spanish and click Translate.
4. Repeat for each slide you want in both languages.

Both languages on the same slide

1. Duplicate the English text box (Ctrl+D) and place the copy below the original, in a different colour or in italics so readers can tell the languages apart.
2. Select the copy, tick Translate only the selected text or frame and translate it to Spanish.

Leave room for the second language: on a crowded slide, two languages at full size rarely fit, so cut the English down first.

Spanish-specific tips

Spanish takes more room

A commonly cited estimate is that Spanish text runs roughly 20–30% longer than the English it comes from. Short headings and button-style labels often grow the most. Our add-on tells the AI to stay as close to the original length as it can, but some growth is normal. Fixes: select a box and choose Format options → Text fitting → Shrink text on overflow, shorten the English before translating, or add “keep headings short” to the prompt.

Tú or usted

Spanish has two ways to say “you”. Usted is formal and respectful; tú is informal and friendly. For letters and presentations to parents and families, usted is the safer choice; for slides addressed to students, especially young ones, tú is usual. Machine translation picks one on its own and can switch between them, so say which one you want in Prompt / context and check a few slides.

Latin American or Spain Spanish

The add-on has one “Spanish” in its language list; to get a regional variety, ask for it in Prompt / context — for example “Latin American Spanish (Mexico)” or “Spanish as used in Spain”. The differences show up in vocabulary (computadora vs ordenador) and in the plural “you”: Latin America uses ustedes for everyone, Spain uses vosotros informally. For US families, Latin American Spanish is usually the right default.

Dates, numbers and punctuation

• Dates go day-first: October 16, 2026 becomes 16 de octubre de 2026, and 10/16 becomes 16/10 — easy to misread at a glance, so spell out important dates.
• Days and months are lowercase in Spanish (lunes, octubre).
• Questions and exclamations open with ¿ and ¡; check they survived if you pasted text by hand.
• The decimal separator depends on the country (Spain uses a comma, Mexico a point), which is another reason to name the variety you want.
