An LRC file is a plain text file using the .lrc extension that pairs each line of song lyrics with a timestamp in [mm:ss.xx] form, so compatible music players can highlight the correct words as the track plays. To get an LRC file for a song, you can try to download one a stranger has shared online, scrape one from a lyrics service, or build one yourself from lyrics text you already own using a local generator. The local route is the most reliable for several reasons: it keeps your lyrics private, works for any song you have permission to use, and gives you direct control over the start time, the spacing between lines, and the optional title, artist, and album metadata that appear in supported players.
The simple LRC format is a de-facto family rather than a single formal specification, so different players tolerate slightly different subsets. A generator that emits the conservative [mm:ss.xx] subset plus optional [ti:], [ar:], and [al:] tags produces files that load in most modern players without surprises. The de-facto form itself is documented on QuickLRC's format reference, which describes bracketed [mm:ss.xx] line timestamps as the core element of a simple LRC file. Independent parsers such as Subforge's LRC time module confirm that minutes contribute sixty thousand milliseconds, seconds contribute one thousand, and the two fractional digits represent centiseconds.
What's Inside a Simple LRC File
A simple LRC file is divided into two regions: a small metadata block at the top and the timed lyric body below it. The metadata block holds zero, one, two, or three optional tags, each on its own line, written as [xx:value] where xx is a two-letter code. The lyric body then lists one timestamped line per display event. A blank line is often inserted between the metadata and the first timed line for readability, but the timed rows themselves remain ordinary plain text.
| Tag | Purpose | Example |
|---|---|---|
| [ti:...] | Song title shown by some players | [ti:Midnight Drive] |
| [ar:...] | Artist or performer | [ar:J. Rivera] |
| [al:...] | Album name | [al:Northbound] |
| [mm:ss.xx] | Display timestamp for the next lyric line | [01:23.45]Example line |
The minute field accepts two or three digits, the seconds field must be 00 through 59, a period separates the seconds from the centiseconds, and exactly two centisecond digits follow. The tool does not emit hour fields, colon-separated frames, three-digit milliseconds, enhanced word-level angle-bracket timestamps, karaoke duet markers, or player-specific extensions, which keeps the output portable.
Why Shared LRC Files Often Disappoint
Searching the open web for an LRC file looks convenient but rarely delivers the file you actually need. Community uploads are usually scrubbed from forum threads, pastebins, or comment chains that no longer exist, and the surviving copies are often encoded in older Windows code pages instead of UTF-8, which mangles accented letters and non-Latin scripts the moment another player opens them. Many shared files carry the wrong artist or album name because the uploader never double-checked the [ar:] and [al:] fields.
Some shared files have been machine-translated from another language, and others carry a copyright status the uploader never confirmed. Even when the file is technically correct, the spacing rarely matches your specific recording: a live take, a remastered version, and an extended remix will all demand different timestamps for the same set of words, and a downloaded file is rarely retimed against your exact master. Building your own LRC with the LRC File Generator sidesteps every one of those problems because it formats text you supply yourself, with the lyric lines preserved verbatim and the metadata fields guarded against hidden tag injection.
Build an LRC File Locally From Your Own Lyrics
The LRC File Generator produces a simple LRC file from lyric text, a start timestamp, and a fixed interval. The whole workflow runs in your browser, shows you the exact file before you download it, and saves it with a sensible .lrc filename. All content and arithmetic stay in the current browser tab; no lyric text is uploaded, stored in an account, or sent to an AI service.
- Paste your lyric text into the input area, one display line per row. The tool accepts up to 500 non-empty lines and up to 50,000 input characters, with at most 500 characters on one line. Blank rows are removed automatically, and Windows, old Mac, and Unix line endings are normalized so the preview always reflects the same content regardless of where the text was copied from.
- Enter the first timestamp in MM:SS.xx form, such as 00:12.34. Two or three minute digits are allowed, the seconds must be 00 through 59, and exactly two centisecond digits must follow the period.
- Set the interval between successive lines in seconds, with up to two decimal places, anywhere from 0.01 to 600.00. The value is converted to an integer number of centiseconds before any rows are produced, so repeated addition does not accumulate binary floating-point drift later in the song.
- Optionally fill in the title, artist, and album fields. Each becomes a [ti:], [ar:], or [al:] tag, is trimmed, limited to 120 characters, and cannot contain square brackets or control characters, which prevents one field from injecting an extra LRC tag into the output. Empty metadata fields are omitted entirely.
- Read the preview to confirm the first and last timestamps look right. The preview is the exact text that will be saved, so editing any input clears the previous preview and forces a fresh render.
- Click Download to save the file. The download uses UTF-8 text without a byte-order mark, and the filename is derived from the title (with unsafe punctuation replaced by hyphens) or falls back to synced-lyrics.lrc when no title was set.
Reading the [mm:ss.xx] Timestamp Format
The numeric format looks intimidating at first but is just a fixed-width time broken into three fields. The minutes are unbounded within two or three digits, the seconds are always two digits from 00 through 59, and the centiseconds are always two digits from 00 through 99. Here are the only shapes the parser accepts as a starting timestamp:
| Input | Meaning |
|---|---|
| 00:00.00 | The very start of a track |
| 09:59.99 | Last second of a 10-minute song |
| 10:00.00 | First second after the 10-minute mark |
| 123:45.67 | Long-form track at 2 hours, 3 minutes, 45 seconds |
To see how the interval arithmetic works, consider a start of 00:12.34 and an interval of 2.50 seconds. Converting 00:12.34 to centiseconds gives (12 × 100) + 34 = 1234 centiseconds. Converting 2.50 seconds to centiseconds gives 2.50 × 100 = 250 centiseconds. Adding 250 to 1234 gives 1484 centiseconds for line two, and adding another 250 gives 1734 centiseconds for line three. Translating those centisecond totals back to the visible format:
- Line 1: 1234 cs → 12 seconds and 34 centiseconds → 00:12.34
- Line 2: 1484 cs → 14 seconds and 84 centiseconds → 00:14.84
- Line 3: 1734 cs → 17 seconds and 34 centiseconds → 00:17.34
If a calculated final timestamp would exceed 999:59.99, generation fails outright and nothing is silently truncated. The interval itself is accepted as a decimal because it is easier to type 2.5 than 2.50, but the generator stores it as an integer so that a 200-line song stays as close to the intended tempo as the centisecond format allows.
Fine-Tuning the Output in a Dedicated Editor
A fixed interval is only a starting draft. Real vocals rarely begin at perfectly equal spacing, and the generator does not listen to audio, detect speech, transcribe lyrics, align phonemes, identify beats, or estimate performance timing in any way. Once the LRC file is downloaded, open it beside the exact recording you intend to play it with, and nudge individual lines in a dedicated LRC or subtitle editor. Most editors let you load the file, press play, tap a key at each line boundary, and overwrite the timestamp with the captured playback position. The file itself stays a plain text document throughout, so any text editor can also be used for manual touch-ups.
Different players also interpret the same file differently. Some ignore the [ti:] tag, others reject minute values above 99, and a few do not accept centisecond precision at all. Always test the produced file in your target player before assuming the draft is final, and remember that the tool does not supply copyrighted lyrics, search a catalog, identify a song, confirm ownership, or grant a synchronization license; you must have permission to reproduce and distribute any lyric text you enter. If your target is a video editor or karaoke workflow rather than a music player, the SRT format with exact timestamps might be a better fit and is covered in a separate walkthrough.
