Translate Spanish subtitles to English
Last updated September 2026
Found a video with only Spanish subtitles? You can translate the Spanish .srt or .vtt file into English right in your browser. Spanish uses the Latin alphabet with accents (á, é, í, ó, ú), ñ and the inverted marks ¿ and ¡ that open questions and exclamations. The tool sends each cue's text to the on-device translation model in desktop Chrome or Edge and writes the English back with the original timing, so the new file stays in sync with the video. The file never leaves your computer.
How to do it
- Get the Spanish subtitle file as .srt or .vtt, and make sure it's saved as UTF-8 (see the tips below if the text looks garbled).
- Open the translator in desktop Chrome 138+ or Edge — the button here presets Spanish → English.
- Drop the file in. If the browser supports language detection, it will confirm the source is Spanish.
- Press Translate. The first run downloads the Spanish–English model once; later files in the same pair start immediately and work offline.
- Download the English subtitle file and load it next to your video (same file name as the video makes most players pick it up automatically).
Tips
- Regional slang (Mexican, Argentine, Caribbean) can translate literally; idioms are the lines most worth a human glance.
- Spanish often omits subjects, so check that pronouns in the English output match who is speaking.
- Machine translation is a strong first draft. For anything you'll publish, have someone fluent in Spanish spot-check names and jokes.
FAQ
Will it handle Spanish accents in old SRT files?
If the file is UTF-8, yes. Older Spanish SRTs are sometimes saved as Windows-1252 or ISO-8859-1, which can make accents appear as “é”. Re-save the file as UTF-8 in a text editor before translating.
Is my Spanish subtitle file uploaded anywhere?
No. The file is read and translated inside your browser by its built-in model. Only anonymous usage analytics are collected — never file contents.
Why does it say my browser isn't supported?
The on-device Translator API currently exists only in desktop Google Chrome 138+ and Microsoft Edge. Brave, Opera, Firefox, Safari and all mobile browsers either lack the API or the model.
