Translate Subtitles Online Free — 100+ Languages, No Software Required
Need subtitles in another language? Paste a video URL, pick your language, get translated subtitles. Works in Telegram — no software to install.
How It Works
Most online subtitle translators require you to upload an SRT file. Then they translate the text and give you back another SRT file. Then you need a separate tool to merge the subtitles into the video.
Subly does everything in one step:
- Paste a video URL (YouTube, TikTok, Instagram) into Telegram
- Choose your target language (100+ options)
- Get back a video with burned-in subtitles + a downloadable SRT file
No file uploads. No separate tools. No technical knowledge needed.

Why AI context matters
When you translate an SRT file line by line through Google Translate, each subtitle is translated independently. The translator doesn't know what came before or after. This produces awkward, disconnected translations.
Subly's AI (Google Gemini) translates subtitles in context — it sees the full conversation, understands who's speaking, and produces natural-sounding translations that flow properly.
