Frequently asked questions
Will I lose the subtitle styling?
Yes, SRT has no fonts or positions. To keep the look, burn the ASS file into the video with Burn Subtitles instead.
What about signs and karaoke effects?
Drawing commands and karaoke timing tags are removed. Overlapping sign lines become separate SRT entries.
What is the difference between SRT and VTT?
Both list numbered lines with start and end times. SRT uses commas in times (00:01:02,500) and is the most widely supported. VTT uses dots, starts with a WEBVTT header and is the format web video players need.
What happens to ASS styling when converting to SRT?
SRT has no positions or detailed styles, so they are removed and only the text and timing remain. Italic and bold are kept where possible.
What does Text output contain?
Only the spoken lines, without numbers or times. Useful as a transcript or for translation.
Is my file uploaded?
No. Conversion runs in your browser.
Can it read files with different encodings?
UTF-8 and UTF-16 files are detected automatically. Older files in other encodings may show wrong characters; re-save them as UTF-8 first.
Does it work on phones?
Yes. It is instant on any device.
