Subtitle Converter

Choose an SRT, VTT, ASS, SSA, or SBV subtitle file, then select the format you need. Cue timing and text are converted automatically; styling that the target format cannot represent is removed.

SUB supports both SubViewer / MicroDVD text and VobSub image subtitles; VobSub text is recovered with OCR. Text subtitle files are processed on your device. Image-based VobSub files are uploaded securely for OCR and deleted after the conversion task.

How to use: add a SRT, WebVTT, ASS, SSA, SBV, LRC, TTML / DFXP, SMI / SAMI, SUB file, then choose SRT, WebVTT, ASS, SSA, SBV as the output format and start the conversion. If the filename has the wrong extension, we try to recognize the actual format and use a suitable conversion method. Upload the original file without renaming it. If it cannot be read, export a new copy from its original app. Images sent for text or Word output use text recognition; check the recognized content. Check that the file opens in its original application. Download it again if incomplete, or export a new copy. Changing the extension does not convert the file format. After downloading, choose another file to continue without refreshing the page. If a download stops, use the download link to try again. Text files automatically recognize UTF-8, UTF-16, GBK/GB18030, Big5, Shift_JIS, EUC-KR, and common Western encodings, so you normally do not need to change the encoding first. Choose your SUB file and select an output such as SRT. SubViewer and MicroDVD text subtitles are recognized automatically and converted on your device, preserving timing and line breaks. Image-based VobSub subtitles are uploaded for text recognition, may take longer, and should be checked after conversion. File size limit: SRT, VTT, SBV, and LRC up to 5 MB; ASS, SSA, TTML, DFXP, SMI, SAMI, and SUB up to 20 MB. Large files may take longer to convert. LRC lyrics need a time tag such as [00:01.00] before each lyric line to show when it should appear. Plain lyrics without time tags cannot be converted into timed subtitles. Download a timed LRC file, or add timings first.
