Do your subtitles look like random symbols or garbage text? If you see characters like é, ñ, or å instead of normal letters, your file has an encoding issue. TheSubAI Subtitle Encoder fixes this instantly by converting your file to the universal UTF-8 standard.

Fixing broken characters takes just a click:

- Convert: Ensure the "Target Encoding" is set to UTF-8 (Recommended).
- Download: Get your fixed subtitle file that works on any TV, media player, or streaming service.
Supported Character Encodings
We support conversion from all major legacy code pages to modern Unicode:
- Western European: Windows-1252 (ANSI), ISO-8859-1 (Latin-1) — Fixes accents like é, á, ñ.
- Central European: Windows-1250, ISO-8859-2 — Fixes Polish, Hungarian, Czech characters (ő, ű, ł, ž).
- Cyrillic: Windows-1251, ISO-8859-5 — Fixes Russian, Bulgarian, Serbian text.
- Unicode: UTF-8, UTF-8 with BOM, UTF-16 LE/BE.
Why convert subtitles to UTF-8?
UTF-8 is the modern standard for text. Many Smart TVs (Samsung, LG), media players (VLC, Plex), and websites (YouTube) only accept UTF-8 subtitles. If your file is saved in an older format like ANSI or Windows-1252, special characters will break. Our tool ensures 100% compatibility.
