Free online LRC to SRT converter

LRC and SRT are both subtitle-related file formats, but they serve slightly different purposes. LRC files are commonly used for synchronized lyrics, where each line is paired with a timestamp for music playback. SRT files are standard subtitle files used in videos, containing sequential subtitle entries with start and end times, making them suitable for movies, tutorials, and other video content.

What is an LRC file

An LRC file stores lyrics with time tags, usually in a simple line-based format. It is widely supported by music players, karaoke apps, and lyric display tools. Each line typically appears at a specific playback time, but it usually does not include subtitle duration information.

What is an SRT file

An SRT file is a subtitle format that uses numbered blocks, time ranges, and subtitle lines. Each subtitle entry has a start time and an end time, which makes it ideal for video subtitles and closed-caption style playback.

How to convert LRC to SRT

To convert LRC to SRT, the timestamped lyric lines must be transformed into subtitle blocks with proper start and end times. Since LRC usually provides only one timestamp per line, the converter often uses the next lyric timestamp as the end time for the current subtitle. If the last line has no following timestamp, a default duration is assigned.

The conversion process usually includes:

• Reading each LRC timestamp and lyric line
• Sorting timestamps in chronological order
• Creating SRT numbered entries
• Assigning subtitle end times based on the next timestamp
• Saving the result in standard SRT format

Best software for conversion

The best choice depends on whether you want a quick online conversion or manual control. For fast and accurate results, a dedicated subtitle converter is usually the easiest option. If you need editing features, subtitle editors are better because they let you adjust timing before exporting.

Recommended tools:

• Aegisub — excellent for subtitle editing and timing adjustments
• Subtitle Edit — very good for converting and refining subtitle files
• Online subtitle converters — convenient for simple LRC to SRT conversion

If you already work with subtitles, Subtitle Edit is often the best overall option because it supports importing lyric-style timing and exporting to SRT with precise control.

How to convert with Subtitle Edit

1. Open Subtitle Edit
2. Use File → Open to load the LRC file
3. Check and adjust timestamps if needed
4. Use File → Save as and choose SRT
5. Save the converted subtitle file

Things to check after conversion

After converting, review the subtitle timing to make sure each line appears long enough to read. Because lyric lines are often shorter than video subtitles, you may need to extend some durations or merge lines for better readability.

Important: If the original LRC file contains only lyric timing and no real subtitle durations, the converted SRT file may need manual cleanup for video use.

Summary

LRC to SRT conversion is useful when synchronized lyrics need to be turned into standard video subtitles. The process is straightforward, but the quality of the result depends on timing accuracy and subtitle readability. For the best balance of ease and control, Subtitle Edit is a strong choice.
