Any one can be converted to any other.","Will my subtitle file get uploaded to your server?","No. The entire conversion happens in your browser using JavaScript — no upload, no server processing, no log. Works offline once the page is loaded.","Why does my converted LRC file lose end times?","LRC was designed for music lyrics and only stores when each line should appear, not when it should disappear. So converting any time-range subtitle (SRT\u002FVTT\u002FASS\u002FSBV) to LRC discards the end time. Converting LRC back to SRT works but each line uses the next line's start as its end.","My ASS subtitle has fancy styles and effects — will they survive the conversion?","We preserve text and timing for all formats, but advanced ASS features (custom fonts, colors, animations, karaoke effects, positioning tags) are stripped when exporting to SRT\u002FVTT\u002FSBV\u002FLRC because those formats don't support them. ASS-to-ASS roundtrip keeps everything.","Can I batch convert dozens of files at once?","Yes — drop a whole folder of subtitle files into the upload area, pick one target format, and download everything as a ZIP.

HTML5 播放器报错？把 ASS 给老 PotPlayer 显示一片乱码？把 YouTube 下载下来的 SBV 想拿去 B 站重新上字幕？字幕格式互转是中文创作者每天都会撞到的痛点。但 2026 年你能找到的中文字幕转换工具有限，常见的两类：\u003Cstrong>需要上传到第三方服务器\u003C\u002Fstrong>（隐私敏感）或者 \u003Cstrong>UI 像 2010 年\u003C\u002Fstrong>。\u003C\u002Fp>\n\u003Cp>MeTool 字幕格式转换器把 5 个最常用格式做成一个干净的纯前端工具：\u003Cstrong>SRT、VTT、ASS、SBV、LRC\u003C\u002Fstrong> 任意两种之间互转。整套流程在浏览器里完成，\u003Cstrong>字幕文件从不上传\u003C\u002Fstrong>。一次拖入一整批文件，选目标格式，几秒钟下载 ZIP。\u003C\u002Fp>\n\u003Cp>关键场景：把 Bilibili \u002F Aegisub 的 ASS 转 SRT 给老电视播放器、把 SRT 转 VTT 给 HTML5 video 元素、把 .lrc 歌词转 SRT 给视频剪辑软件、把 YouTube 旧版 SBV 字幕转成现代格式。\u003C\u002Fp>\n\u003Ch2>5 种字幕格式各自的取舍\u003C\u002Fh2>\n\u003Ch3>SRT (SubRip) — 最通用\u003C\u002Fh3>\n\u003Cp>互联网最早期的字幕格式，几乎所有播放器都识别。结构最简：序号 + 时间 + 文本。\u003Cstrong>毫秒级精度\u003C\u002Fstrong>。如果不知道选什么，选 SRT。\u003C\u002Fp>\n\u003Ch3>VTT (WebVTT) — HTML5 标配\u003C\u002Fh3>\n\u003Cp>HTML5 \u003Ccode><track>\u003C\u002Fcode> 元素的官方字幕格式，被所有现代浏览器原生支持。语法接近 SRT 但用 \u003Ccode>.\u003C\u002Fcode> 而不是 \u003Ccode>,\u003C\u002Fcode> 分隔毫秒，并且支持简单的样式 \u002F 行内标签。Web 视频用 VTT。\u003C\u002Fp>\n\u003Ch3>ASS (Advanced SubStation Alpha) — 动漫字幕组的最爱\u003C\u002Fh3>\n\u003Cp>支持自定义字体、颜色、动画、卡拉 OK 特效、定位标签。Aegisub 编辑器原生格式，B 站 \u002F Bilibili 上的高级字幕大多是 ASS。MeTool 转换会保留文本和时间，但\u003Cstrong>样式信息在转 SRT\u002FVTT\u002FSBV\u002FLRC

早期的字幕导出格式，没有序号、没有头，时间字段间用「逗号」分隔（容易被误解析）。\u003Cstrong>厘秒精度\u003C\u002Fstrong>。从 YouTube CC 下载下来的字幕通常是 SBV 或 SRT。\u003C\u002Fp>\n\u003Ch3>LRC (Lyric) — 音乐播放器歌词\u003C\u002Fh3>\n\u003Cp>为音乐设计的同步歌词格式，只有起始时间没有结束时间。同一行可以有多个时间标签（同句歌词出现多次）。\u003Cstrong>转出 LRC 时一定会丢失结束时间信息\u003C\u002Fstrong> — 这不是 bug 是格式所限。\u003C\u002Fp>\n\u003Ch2>为什么字幕格式转换不应该在云服务器跑\u003C\u002Fh2>\n\u003Cp>字幕文件本质是\u003Cstrong>文本\u003C\u002Fstrong>，体积小（多数 < 100KB），但内容敏感度可能很高：未发布的视频脚本、内部培训内容、客户访谈逐字稿、医疗 \u002F 法律录音转写。把这些文本传到第三方服务器，本身就是隐私风险。\u003C\u002Fp>\n\u003Cp>很多在线字幕工具的商业模式就是「免费转换 + 收集字幕语料训练 NLP 模型」。文件传上去你就\u003Cstrong>没办法证明\u003C\u002Fstrong>对方有没有保留副本。\u003C\u002Fp>\n\u003Cp>MeTool 用纯 JavaScript 在浏览器解析、再序列化字幕，\u003Cstrong>压根没有上传环节\u003C\u002Fstrong>：DevTools Network 面板里看不到任何字幕相关请求。这意味着哪怕断网（页面已加载完成），转换功能依然可用。\u003C\u002Fp>\n\u003Cp>这种「不上传」的能力是天生的，不是营销话术。底层只用了 JavaScript 字符串处理 + Blob 下载 — 没有任何技术理由需要服务器参与字幕格式转换。\u003C\u002Fp>\n\u003Ch2>常见使用场景与对应技巧\u003C\u002Fh2>\n\u003Ch3>场景 1：B 站投稿要求 SRT，本地是 ASS\u003C\u002Fh3>\n\u003Cp>把 ASS 拖入工具，选 SRT，下载。如果 ASS 含特效，会被剥离，但文本和时间完整保留 — 重新在剪辑软件里给 SRT

\u003Ccode><track>\u003C\u002Fcode> element and the browser refuses? Got an ASS that an old PotPlayer renders as garbled boxes? Downloaded an SBV from YouTube but your editing app insists on SRT? Subtitle format mismatch is a daily headache. The tools you can find in 2026 mostly fall into two camps: \u003Cstrong>upload-to-third-party servers\u003C\u002Fstrong> (privacy-hostile) or \u003Cstrong>UIs that look like 2010\u003C\u002Fstrong>.\u003C\u002Fp>\n\u003Cp>MeTool's subtitle converter packages the five most common formats into a clean, fully browser-based tool: \u003Cstrong>SRT, VTT, ASS, SBV, LRC\u003C\u002Fstrong> — convert any to any. Files are parsed and rewritten in your browser; \u003Cstrong>nothing is uploaded\u003C\u002Fstrong>. Drop a whole batch in once, pick a target format, download the ZIP in seconds.\u003C\u002Fp>\n\u003Cp>Common cases: ASS → SRT for legacy TV players; SRT → VTT for HTML5 video; LRC lyrics → SRT to import into a video editor; YouTube's old SBV → SRT for a modern workflow.\u003C\u002Fp>\n\u003Ch2>Five Subtitle Formats and What Each Trades Off\u003C\u002Fh2>\n\u003Ch3>SRT (SubRip) — The Lingua Franca\u003C\u002Fh3>\n\u003Cp>The earliest broadly-adopted subtitle format. Almost every player on every platform reads it. Simplest possible structure: index + time line + text. \u003Cstrong>Millisecond precision.\u003C\u002Fstrong> When in doubt, choose SRT.\u003C\u002Fp>\n\u003Ch3>VTT (WebVTT) — Standard for HTML5\u003C\u002Fh3>\n\u003Cp>The official subtitle format for HTML5 \u003Ccode><track>\u003C\u002Fcode> elements, natively supported by every modern browser. Syntax mirrors SRT but uses \u003Ccode>.\u003C\u002Fcode> instead of \u003Ccode>,\u003C\u002Fcode> for milliseconds and supports inline styling tags. Use VTT for web video.\u003C\u002Fp>\n\u003Ch3>ASS (Advanced SubStation Alpha) — Anime Fansub Favorite\u003C\u002Fh3>\n\u003Cp>Supports custom fonts, colors, animations, karaoke effects, positioning tags. Native to the Aegisub editor; most high-quality fan subtitles ship as ASS. MeTool preserves text and timing during conversion, but \u003Cstrong>style information is stripped when going to SRT\u002FVTT\u002FSBV\u002FLRC\u003C\u002Fstrong> (those formats simply don't support it).\u003C\u002Fp>\n\u003Ch3>SBV (SubViewer) — YouTube's Old Caption Format\u003C\u002Fh3>\n\u003Cp>YouTube's early caption export format. No index, no header, time fields separated by commas (which can confuse parsers). \u003Cstrong>Centisecond precision.\u003C\u002Fstrong> Captions downloaded from YouTube are usually SBV or SRT.\u003C\u002Fp>\n\u003Ch3>LRC (Lyric) — Music Player Lyrics\u003C\u002Fh3>\n\u003Cp>Designed for music sync — only stores start times, no end times. Multiple time tags can share one line (same lyric repeating in the song). \u003Cstrong>Going to LRC always loses end-time information\u003C\u002Fstrong> — that's a format limitation, not a bug.\u003C\u002Fp>\n\u003Ch2>Why Subtitle Conversion Should Never Run on a Cloud Server\u003C\u002Fh2>\n\u003Cp>Subtitle files are \u003Cstrong>plain text\u003C\u002Fstrong>, usually tiny (most under 100 KB) — but the content can be high-sensitivity: unreleased video scripts, internal training material, customer interview transcripts, medical or legal recordings. Sending that text to a third-party server is itself a privacy risk.\u003C\u002Fp>\n\u003Cp>Many "free online subtitle tools" monetize by collecting subtitle corpora to train NLP models. Once you've uploaded the file, you have \u003Cstrong>no way to prove\u003C\u002Fstrong> the operator didn't keep a copy.\u003C\u002Fp>\n\u003Cp>MeTool parses and re-serializes subtitles entirely in your browser using JavaScript. \u003Cstrong>There is no upload step at all\u003C\u002Fstrong>: the DevTools Network panel shows zero subtitle-related requests. The tool keeps working offline once the page has loaded.\u003C\u002Fp>\n\u003Cp>This "no upload" property isn't marketing — it falls out of the architecture. The implementation is just JavaScript string handling + Blob downloads. There's no technical reason a server needs to be involved in subtitle format conversion.\u003C\u002Fp>\n\u003Ch2>Common Workflows and Tips\u003C\u002Fh2>\n\u003Ch3>Use case 1: YouTube wants SRT, you have ASS\u003C\u002Fh3>\n\u003Cp>Drop the ASS in, pick SRT, download. ASS effects get stripped, but text and timing carry over intact — re-style in your editor afterward.\u003C\u002Fp>\n\u003Ch3>Use case 2: HTML5 video needs VTT, you have SRT\u003C\u002Fh3>\n\u003Cp>Pick VTT and the tool adds the \u003Ccode>WEBVTT\u003C\u002Fcode> header and replaces \u003Ccode>,\u003C\u002Fcode> with \u003Ccode>.\u003C\u002Fcode> for milliseconds.\u003C\u002Fp>\n\u003Ch3>Use case 3: Downloaded SBV from YouTube for a video editor\u003C\u002Fh3>\n\u003Cp>Almost every video editor (Premiere, Final Cut, DaVinci Resolve, CapCut) prefers SRT. Just go SBV → SRT.\u003C\u002Fp>\n\u003Ch3>Use case 4: Spotify-style .lrc lyrics into a video\u003C\u002Fh3>\n\u003Cp>LRC → SRT fills in each line's end time using the next line's start (last line gets a 5-second fallback). Tweak by hand if needed.\u003C\u002Fp>\n\u003Ch3>Use case 5: Batch-process a whole season of subtitles\u003C\u002Fh3>\n\u003Cp>Drop all 24 episodes' .ass files in at once, pick SRT, hit "Download all
