Your style
Size, position, colour, outline, box and shadow, chosen to suit the video.
Many scripts
Latin, Devanagari and other scripts render with bundled fonts, so Hindi subtitles display correctly.

Frequently asked questions
What is the difference between burned-in and soft subtitles?
Burned-in subtitles are drawn into the picture and always show. Soft subtitles are a separate track viewers can turn on and off, but many social apps ignore them. Burn them in for social media; keep them soft for YouTube and streaming.
I do not have a subtitle file. What now?
Use Auto Subtitles to create one from the speech, then come back and burn it in. You can also write an SRT by hand in any text editor.
My ASS file has its own styles. Are they used?
Yes. ASS files keep their own fonts, colours and positions. The style options here mainly apply to SRT and VTT files.
The subtitles are early or late. How do I fix that?
Shift the timing with Subtitle Sync Fixer, then burn the corrected file.
Is my video uploaded?
No. The subtitles are rendered and the video encoded entirely in your browser.
Can I burn subtitles in on my phone?
Yes. It re-encodes the whole video, so short clips are quickest on a phone.
Which size should I use for vertical videos?
M or L. Vertical video is narrow, so very large text wraps onto many lines. Keep each subtitle line short for Reels and Shorts.
