LINE Recording Length Guide 2026: Limits, Saving, and Transcription

Don't Rush to Record: 3 Misconceptions About LINE Recording

The first misconception is the most common: thinking LINE has a built-in call recording feature. In reality, LINE does not provide a built-in record button, and you won't find any recording button during a call. To capture call content, you can only rely on your phone's screen recording, a second device to pick up audio, or a third-party recording app.

The second misconception is conflating "voice message length" with "call recording length." These two have completely different sources of limitation, which will be explained separately below.

The third misconception is the most costly: thinking recordings are automatically saved. In fact, voice messages in LINE chats over 50 MB are only kept for 30 days; for long-term storage, you must manually download or save them to Keep. By the time you think to look for them, the file may already be gone.

How Long Can LINE Recordings Actually Be? Three Scenarios

1. LINE Voice Messages: Official Limit Is File Size, Not Seconds

LINE has not published a specific maximum length in seconds for voice messages; what is public is the file size limit: a single file must be under 200 MB to send successfully. In practice, if you record a long message but can't send it, it's usually not because of "too many seconds" but because the file is too large. It's recommended to record in segments, send in segments, or save the file and split it yourself.

Storage duration also depends on size:

• Under 50 MB: Can be stored permanently in the chat.
• Over 50 MB: Only kept in LINE for 30 days; back up as soon as possible.

LINE's built-in Keep offers 1 GB of free space, and saving voice messages there is a common preservation method. Note that you can usually only process one voice message at a time, which can be time-consuming if you have many.

2. LINE Call Recording: Length Depends on Your Tool, Not LINE

Since LINE has no built-in recording, how long you can record a call depends entirely on your method. The three common interruption points are phone battery, storage space, and system limitations. To record a meeting call over an hour, it's best to charge while recording, check remaining space, and do a 1-minute test recording beforehand to ensure the audio is working.

3. Legal and Etiquette: Get Consent Before Recording

Recording involves local laws and both parties' willingness. In practice, it's advisable to inform the other party before recording; for meeting calls, state at the beginning that "this meeting will be recorded for documentation" to avoid later disputes.

The Real Trouble Starts After Recording: Using Tinrec to Turn Long Recordings into Usable Data

Honestly, the most painful part of recording isn't the recording itself—it's having to listen to it again afterward. A one-hour call often takes another hour and a half to re-listen and organize notes.

Take Tinrec as an example: it can upload already-recorded audio or video files, convert them into searchable transcripts, and automatically generate summaries, chapters, and action items. In other words, the file from your LINE call can be imported into Tinrec and turned into a readable record, rather than an audio file sitting on your phone.

After transcription, you can continue to use it. You can ask Tinrec directly, for example, "When is the delivery date the client mentioned?" It will find the relevant passage based on semantics and answer. When you need to share with colleagues or clients, you can export it as a document or take it to Notion, Google Docs, OneNote, Dropbox, and other tools for further editing.

For team use, Tinrec's team version centralizes meeting data in one space: members can share and view, administrators can manage roles, seats, usage, and audit logs, and when members leave, data remains with the team rather than disappearing with individual accounts.

3 Practical Use Cases

Scenario 1: Client Conference Call After the call, import the recording into Tinrec, and with transcript plus summary and action items, you can quickly send meeting minutes to the client for confirmation.

Scenario 2: Interviews and Lecture Recordings Interviews lasting one to two hours often risk missing key quotes. Tinrec's searchable transcript means you don't have to drag the progress bar to find a specific sentence.

Scenario 3: Cross-Language Meetings Tinrec covers Chinese, Traditional Chinese, and multilingual content, and can display translations during recording, making mixed Chinese-English meeting notes much easier.

4 Things to Consider When Choosing a Recording-to-Text Tool

1. Performance with Chinese and Mixed Chinese-English Don't just rely on official claims; test with your own real recording. Tinrec covers Chinese and multilingual scenarios, but actual results can still be affected by recording quality, accent, noise, and overlapping speakers. For important content, it's recommended to verify against the original.

2. What You Can Do After Transcription Transcripts are just the starting point. Tinrec further produces summaries, chapters, action items, and mind maps, and allows you to ask follow-up questions about the content.

3. Audio Retention and Export Some tools only keep text and not audio, making future verification difficult. Tinrec retains audio and supports multi-format export to common workflows.

4. Personal vs. Team Use For personal use, the free version's basic quota is enough for occasional organization needs. For teams sharing data, you'll need to look at the team version's seats and management capabilities. Tinrec for Teams is based on team spaces; first-time eligible users can try 7 days, 1 free seat, 300 minutes shared import quota; monthly USD 29.80 per paid seat per month, annual USD 199 per paid seat per year (about USD 16.58 per month), each paid seat provides 2,000 minutes shared import quota per month. Prices and benefits are subject to the official purchase page.

Frequently Asked Questions

Q1: What is the maximum length for LINE recording? LINE itself has no recording feature; length depends on your recording tool, phone battery, and storage space, with no official LINE limit.

Q2: What is the maximum length for a LINE voice message? There is no official limit in seconds; the public limit is 200 MB file size. If you can't send it, the file is usually too large; record in segments or save and split.

Q3: After a LINE call ends, can I retrieve the recording? No. LINE does not store call audio content, only the time and participants of the call. Without prior recording, it cannot be retrieved afterward.

Q4: Do LINE voice messages expire? Yes. Under 50 MB can be stored permanently in the chat; over 50 MB is only kept in LINE for 30 days. Download or save to Keep as soon as possible.

Q5: Can Tinrec organize LINE call recordings? Yes. First record the call as an audio file, then import it into Tinrec for transcription and summarization. Tinrec handles post-recording organization, not direct recording of LINE calls.

Q6: Is Tinrec's free version enough? For occasional recording organization, the free version's basic quota is enough to try; if you have weekly meetings or interviews, consider the Pro plan; for long-term data storage, the annual plan is more cost-effective.

Conclusion

How long LINE recordings can be isn't determined by LINE, but by what tool you use to record and how you handle it afterward. LINE has no built-in recording, and voice messages are subject to a 200 MB file limit and 50 MB storage period.

The real efficiency gap appears after recording. Instead of spending double time re-listening, let Tinrec organize the transcript, summary, and action items first—the free version's basic quota is enough to try a recording or two and see how much time you can save.
