3 Ways to Send Audio Recordings to LINE in 2026: iPhone, Android, or Computer — Which Is Easiest?

You finished recording but stuck on "how to send" — many people get stuck here

You recorded a two-hour lecture, a half-hour team meeting, and now you need to send it to classmates and colleagues in a LINE group. But when you open Voice Memos, the file is right there in the app — yet LINE can't find the path to select it.

Another common scenario: someone sends a long LINE voice message, and you want to save it. Long-press it, and the options are only Forward, Unsend, Delete — no "Download."

These three situations have completely different workflows. Most people get stuck because they confuse "sending" with "downloading." Below I break down the exact steps I've personally tested, and point out where each step can go wrong.

Before sending a recording to LINE, understand these 4 things

First, is it an "audio file" or a "LINE voice message"?
These two cannot be converted into each other. Voice messages in LINE chats can only be recorded inside LINE. External audio files sent in become file attachments, not the round play button. Once you understand this, you'll stop looking for the nonexistent "how to turn a recording into a voice message" feature.

Second, file format and size.
iPhone Voice Memos records in m4a format, which most phones and computers can play directly. Note that LINE has a file size limit per file — generally under 200MB is safer. For long recordings, check the file size first; if it's too large, split it or compress it before sending.

Third, iOS and Android paths are completely different.
iPhone uses the "Share" menu, while Android uses the system file manager. Paths vary slightly by brand, but the concept is the same. Using the wrong method will make you feel like "LINE can't find my recording."

Fourth, does the recipient really need to listen to the whole thing?
Dropping a 90-minute meeting recording into a group chat puts a lot of pressure on recipients. If the recording is longer than 30 minutes, providing a summary or transcript first is much more considerate than just sending the audio file. I'll cover how to do this efficiently later.

Method 1: Share directly from iPhone Voice Memos to LINE (most intuitive)

This is my most-used and most-recommended method — takes less than 20 seconds.

1. Open the built-in "Voice Memos" app on iPhone, and find the file you want to send on the "All Recordings" page.
2. Swipe left, and tap the "⋯" button.
3. In the share sheet that pops up at the bottom, tap "Share," then select "LINE."
4. If you don't see LINE in the share row, swipe to the far right, tap "More," and enable LINE.
5. Choose the friend chat or group to send to, and tap "Share."

Go back to LINE and you'll see the audio file. The recipient can tap it and press play to listen — format is m4a.

Tip: This sends a "file," not a voice message, so the recipient needs to tap the attachment to play it. It won't automatically appear as voice bubbles in the chat.

Method 2: Upload from Android file manager

Android recordings are usually stored in the "Recorder" or "File Manager" folder. LINE won't find it automatically — you need to locate it manually.

1. First, confirm where the recording is stored. On most brands, it's under "File Manager → Audio" or the recorder app's own folder.
2. Open a LINE chat, and tap "+" in the bottom left corner.
3. Select "File," which opens the system file picker.
4. Find the recording and tap to upload.

File paths vary by brand, so the first search may take some time. Once you find it, note down that folder so you don't have to search again next time.

Method 3: Drag and drop in LINE for desktop (most reliable for long recordings)

If the recording is on your computer, or the file is large, I usually switch to LINE for desktop.

Just drag the audio file into the chat window, confirm the file name and size, and send. It's much more stable than mobile, and upload speed is faster. For meetings or interviews recorded on a computer, use this route — don't send to your phone first and then to LINE, as that just adds more chances for errors.

Tinrec — after recording, how to make sure the message truly "gets through"

Now that I've covered three sending methods, here's the approach I most want to recommend to frequent recorders this year: instead of struggling with how to stuff an audio file into LINE, give the recipient "content they can use directly."

Tinrec is an AI meeting notes and collaboration tool for individuals and teams, available on iOS, Android, web, and desktop. It's not positioned as a "voice recorder" but as a tool that turns recordings into searchable, summarizable, queryable, and exportable data.

During meetings: transcribe while recording — no need for extra notes.
Open Tinrec to record, and the transcript is generated simultaneously. By the time the meeting ends, the AI summary, chapters, and action items are ready — who's responsible for what, and by when, all at a glance. The desktop version is special because it captures system audio directly. For online meetings on Zoom, Google Meet, Microsoft Teams, or Webex, you don't need to invite a meeting bot — no unfamiliar account appears in the participant list.

After recording: ask it questions directly.
This is the most practical part for me. You don't need to Ctrl+F through a 30-minute transcript to find keywords. Just ask "Who mentioned the budget in the last meeting?" or "What were the client's concerns about pricing?" and it answers based on the content. Most competitors in the same price range are still at the "here's a transcript" stage.

When sharing: send the key points, not the file.
When you need to share with colleagues or classmates who don't use Tinrec, export the organized transcript, summary, or action items as a document, then send via LINE. This is especially recommended for long meetings: send the summary first, with a link to the full transcript below, so recipients can dig deeper if needed.

If your team wants to use it together.
The team version isn't "multiple people sharing one account" — it's an independent team workspace. Members can view historical meeting data together, and admins can manage roles, seats, sharing permissions, usage, and audit logs. Currently, the first eligible team trial is 7 days, 1 free seat, and 300 minutes of team shared import quota. Paid plans are USD 29.80 per paid seat per month, or USD 199 annually (about USD 16.58 per month), with 2,000 minutes of team shared import quota per paid seat per month. Under an active team plan, live recording currently does not deduct minutes. Actual prices and benefits are subject to the official purchase page.

Honest limitations.
The free version provides basic quota to try recording, importing, summarizing, and transcribing, but heavy use requires payment. Also, transcription accuracy is affected by recording quality, background noise, accents, and overlapping speech. For important content, verify against transcript timestamps and audio playback.

Who it's for.
If you have two or three meetings a week, often need to turn recordings into something others can understand, or your team's meeting data is scattered across everyone's phones and chat rooms — Tinrec will be much more practical than a simple recording app.

Besides Tinrec, what other options are there?

Otter.ai: A mature English meeting assistant. Basic is free with 300 minutes per month; Pro annual billing is about USD 8.49 per user per month, including 1,200 minutes of in-app recording and 10 file imports per month. If your meetings are entirely in English, the experience is smooth. But Chinese meetings are not its strong suit, and post-meeting Chinese data organization is weaker. Tinrec is better suited for mixed Chinese-English and team data management.

Granola: A bot-free AI meeting notes tool. Basic is free; Business is USD 14 per user per month. It emphasizes "your handwritten notes + AI enhancement," but note that it does not support uploading pre-recorded audio files and does not save meeting audio. If you want to organize recordings you already have, or need to keep the original audio, Granola can't do these two things — Tinrec can.

Notta: A multilingual transcription tool. Free is 120 minutes per month, max 3 minutes per session; Pro annual billing is about USD 8.17 per month, 1,800 minutes per month. It's suitable for simple file transcription and translation, but it lacks Tinrec's desktop bot-free recording for online meetings, and team workspace and seat governance are not its focus.

Pitfall guide: 4 most common mistakes when sending recordings

Pitfall 1: Thinking a voice message can be converted back to a file.
Many people want to save a LINE voice message to their phone, but long-pressing shows no download option. Currently, the most direct way is to long-press the voice message and select "Keep Notes" — the file goes to your LINE Keep space. But that just moves the recording from the chat to another LINE space; the file is still inside LINE. For true preservation, you need to handle it separately.

Pitfall 2: Ignoring file size.
A two-hour lossless recording can easily exceed LINE's sending limit. Check the file size before sending; if too large, split it or convert to a smaller format first.

Pitfall 3: Sending only the audio without key points.
Dropping a 90-minute audio file into a group chat is like dumping the organizing work on everyone. Spend five minutes generating a summary and action items, then attach the full recording — your colleagues will think you're reliable.

Pitfall 4: Storing only in LINE.
Files in LINE chats expire; after a while, they may no longer open. Save important recordings to your own device or cloud drive. Treat LINE as a transfer channel, not storage.

Conclusion: Which method should you use?

• iPhone recording to send to friends or classmates → Voice Memos, swipe left "⋯" → Share → LINE. Fastest.
• Android users → LINE chat "+" → File → manually find the recording folder.
• Meeting recording on computer, file is large → Drag and drop in LINE for desktop is most reliable.
• Want to turn recordings into key points others can understand → Tinrec: transcribe while recording, generate summary and action items after the meeting, export as a document and share via LINE.
• Team needs to view meeting data together → Tinrec team version: replace scattered recordings on everyone's phones with a team workspace and seat management.
• Zero budget, only record English meetings → Otter.ai's free 300 minutes is a reasonable exception.

I recommend trying the free version first, running your own meeting recording through the workflow once, and seeing if the Chinese output is sufficient for your needs. If the quota is enough and the results are smooth, then consider upgrading — no need to pay upfront.
