Spanish captions
Add Spanish subtitles to a video on iPhone
Capster transcribes Spanish audio automatically — the language is detected, so there is nothing to choose — and exports the clip with the captions rendered into the frames. It is one of 99 languages the app handles, and the whole job runs on the phone in about two minutes.

What a Spanish caption looks like
Spanish is the second-most-used language on short-form video after English, and most captioning tools that claim to handle it were tuned on English audio.

Which fonts render Spanish
Checked against every one of the 18 bundled caption fonts in September 2026, by reading each font's own character map rather than trusting its name.
Everything else in the style panel
Text size and colour, outline colour and width, letter case, background, word highlight, layout effect, animation and position all behave exactly as they do in English.
Three things to watch for in Spanish
- Accents change the word, not just the look. Transcription puts the accents in, but a mis-heard word can drop one and change the meaning — año and ano being the example everybody quotes. Read the caption text before you export, not just the timing.
- The opening ¿ and ¡ take horizontal room. A Spanish question sets wider than the same sentence in English. On a vertical clip that is often the line that wraps to three lines and pushes into the platform interface.
- Latin American and peninsular Spanish are not the same transcript. Vosotros forms, seseo and regional vocabulary all come through as spoken. That is correct behaviour, but if you are captioning for one market, expect to edit a handful of words.
How to do it
- 1
Import the clip
Pick a video from Photos. There is no account and nothing to set up, and no language to choose — Capster detects it from the audio.
- 2
Let the Spanish audio transcribe
The audio track is sent for transcription and comes back as Spanish text with word-level timing. The video itself is never uploaded.
- 3
Read the transcript before you style it
Tap any caption to fix a word. Machine transcription of Spanish is good, not perfect, and names are where it slips.
- 4
Pick a style
A style applies to every caption in the clip at once. 17 of the 18 caption fonts cover Spanish.
- 5
Export with the captions burned in
You get one finished video with the captions rendered into the frames, ready to post without switching anything on.
Questions people ask
Can I add Spanish subtitles to a video on my iPhone?
Yes. Capster transcribes Spanish automatically — you do not pick the language, it is detected from the audio — and exports the video with the captions burned into the frames. It is one of 99 languages the app handles, and the whole job happens on the phone.
Which caption fonts work with Spanish?
17 of the 18 caption fonts cover Spanish. Flying Bubble does not. Every other style control works the same as it does in English.
Do I have to choose Spanish before transcribing?
No. The language is detected from the audio, so there is no picker and nothing to get wrong. If a clip mixes two languages, the transcript follows what was actually said, which is usually what you want on short-form video.
Are Spanish captions burned into the video?
Yes. The captions are rendered into the frames rather than attached as a separate subtitle track, so every viewer sees them by default and nothing is lost when the platform re-encodes your upload. There is no SRT file, by design.
Can I try it free?
Yes. 5 transcriptions per install, clips up to 2 minutes, and 2 caption styles, and the export is never blocked — free exports carry a small Capster badge and a short end card instead.
