About MKV to SRT conversion
MKV is an open media container launched in 2002 that can encapsulate multi-track subtitles. It is a standard format for ripped media and media server archiving. Most smart TVs and mobile devices do not natively support reading embedded subtitles. SRT is a plain-text subtitle format with compatibility covering most playback and editing software, so it is necessary to extract subtitles from the container and convert them into a separate SRT file.
The conversion extracts text subtitles from the MKV container to generate an SRT file. The output file is much smaller than the original MKV file. The conversion follows SRT specifications and retains the original timecode precision. SRT does not support styles, positioning and effects, so the corresponding information from the original subtitle is removed during conversion, and no additional parameter adjustment is required for output.
The converted SRT can be used as an external subtitle for smart TVs when playing the original MKV video, supports importing into editing software such as Premiere Pro and Final Cut Pro for subtitle editing, and can also be used for organizing and archiving personal media libraries. Confirm that your playback device supports loading external SRT subtitles before use.

FAQ about MKV → SRT
Does subtitle quality change after conversion
If the original subtitle is in text format, the content and timecode precision are fully retained after conversion. If the original embedded subtitle is in image format, text cannot be extracted directly and converted to SRT.
Will original subtitle styles be preserved
SRT does not natively support style, positioning and effect information. After conversion, the original subtitle's style, position and karaoke effects cannot be retained, only text and timeline are preserved.
What is the single file size limit
This tool has an upload limit of 50MB per single file, and only supports converting one file at a time. Files exceeding the size limit will be rejected for processing.
Will uploaded files be stored
Conversion is completed on the server side, files are uploaded via HTTPS, and the server immediately deletes the source file and output file after conversion completes, no storage is performed.
