French → Spanish
To translate French subtitles to Spanish, upload your .srt or .vtt file to SubLingo, set the target language to Spanish, and download the file with every timecode preserved. Spanish and French land at similar line lengths (within a few percent), so existing line breaks usually still fit. Spanish opens questions and exclamations with inverted marks (¿ ¡) and uses ñ and accented vowels, so the file must stay UTF-8. Keep each line under 42 characters and a reading speed below 17 characters per second — the limit Netflix sets for Spanish subtitles — and save the file as UTF-8 so every character survives the round trip.

Translating from French into Spanish: Spanish and French land at similar line lengths (within a few percent), so existing line breaks usually still fit. Spanish opens questions and exclamations with inverted marks (¿ ¡) and uses ñ and accented vowels, so the file must stay UTF-8. Because SubLingo rewrites only the text inside each cue, every timecode from the original French file carries over to the Spanish version unchanged.
