Turn recordings into transcripts and summaries in minutes
Upload audio or video for multilingual transcription, AI notes, and action items
When you tap on that red exclamation mark, most people's first reaction is to long-press the file and try to "save the recording to the phone." But if the screen already shows "Save period has expired," this option is usually no longer available—no matter how long you press, the file won't appear.
The second common misconception is treating LINE Keep as an indefinite safe deposit box. It is indeed more lenient than the chatroom, but there is a 50MB threshold; anything over that only lasts 30 days.
This article lists 6 methods that have actually helped people recover files, along with their limits. Finally, it explains: rather than regretting it afterward every time, it's better to give important voice messages a second home from the start.
Why do LINE recordings expire?
Files in LINE chatrooms—photos, videos, audio, PDFs—all have a 7-day retention period. After that, they display "Save period has expired, cannot read," and the file itself has been deleted from the server.
Note that this refers to "files in the chatroom." When you make a LINE call with a friend, or record a voice message by holding the microphone in the chatroom, the behavior is not exactly the same as an uploaded audio file; but as long as you receive an audio file, it is subject to the same 7-day rule.
LINE Keep is also not indefinite. Content under 50MB can be stored long-term, but files over 50MB only have a 30-day lifespan in Keep.
In other words, LINE was never designed to be a recording vault.
Option 1 | Tinrec — Turn important voice into searchable text
Let's be clear: Tinrec cannot recover expired LINE files. Its role is to prevent this from happening next time.
Tinrec is an AI meeting notes and collaboration tool for individuals and teams. After converting voice to text, it continues to organize it into summaries, chapters, action items, and even allows you to ask questions about the content.
A few features I find practical:
- Multiple input sources. Supports real-time recording, uploading audio or video files, and desktop recording of online meetings. The desktop version directly captures computer system audio, so when handling Zoom, Google Meet, Microsoft Teams, or Webex, you don't need to invite a bot into the meeting room.
- Workflow after transcription. Transcripts, AI summaries, chapters, action items, mind maps, AI Q&A, real-time bilingual translation—no need to start organizing from scratch after a meeting.
- Export to existing tools. Formats for Notion, Google Docs, OneNote, Dropbox, etc., can be exported without retyping.
- Team space. Meeting data belongs to the team, with separate management of members, roles, and seats, plus usage analytics, audit logs, and an audio recycle bin.
How to choose a plan: The personal version offers a free plan, weekly pass, Pro monthly, and Pro annual—choose based on usage frequency. The team version offers a 7-day trial for first-time eligible users (1 free seat, 300 minutes shared import quota), monthly USD 29.80 per paid seat, annual USD 199 per paid seat (about USD 16.58/month), each paid seat includes 2,000 minutes shared import quota per month, and real-time recording under active seats currently does not deduct minutes. Actual prices and benefits are subject to the official purchase page.
Who it's for: People who frequently attend meetings, conduct interviews, or have a batch of important voice messages they want to preserve content from. Saving voice as text is far more reliable than keeping a file that will disappear in 7 days.
Option 2 | LINE Keep Notes — Official built-in extended storage
Free, built-in, no installation required.
In the chatroom, long-press the file and select Save to Keep, or put the content into Keep Notes, and it escapes the 7-day limit.
Limitations to note: Content under 50MB can be stored long-term; files over 50MB only last 30 days. Also, Keep is a personal space tied to your account, not meant to be a team database.
Who it's for: Users who occasionally need to keep one or two voice messages and whose files are not large.
Option 3 | Forwarding Method — Emergency handling before and after expiration
Find the file in the chatroom, long-press until "Share" appears, then forward it to any chatroom—there's a chance to retrieve the content.
Stop organizing recordings by hand
Upload audio or video and automatically get a transcript, summary, and action items
The key is "chance," not "guarantee." If the file has already been deleted from the server, forwarding won't bring it back. The closer you act to the 7-day boundary, the higher the success rate.
Who it's for: People who just noticed an impending expiration or whose file expired recently.
Option 4 | Phone Cache Recovery — Only works shortly after expiration
If the file expired not long ago and your phone hasn't cleared its cache, in some cases you can retrieve the content from temporary data, though quality is usually lower than the original.
Honestly, this method has a better chance with photos; it applies to audio files much less often. There are also paid recovery software on the market (such as iMyFone ChatsBack) that scan local chat data—whether you can recover depends on how much trace remains on your device. Before spending money, it's advisable to confirm the trial version can find something first.
Who it's for: People whose files expired recently and data is still on the device.
Option 5 | Chat Backup Restore — Only if you backed up beforehand
If you regularly back up LINE chat history to iCloud or Google Drive, you have a chance to recover the audio from the backup.
Two things to note: backups may not include multimedia files, and restoring will overwrite existing chat history on your phone. Think carefully before proceeding.
Who it's for: People who already have a backup habit.
Option 6 | Screen Recording and Call Recording — The zero-cost DIY method
Too late? Remember for next time.
To keep an online meeting, use the system's built-in screen recording; to keep a call, use another phone or a voice recorder. It's free, but you'll have to listen through it yourself afterward—the time cost is actually not low.
Who it's for: People with zero budget and only one or two needs per year.
With so many options, how should you choose?
- Want to recover an already expired file → Try Option 3 forwarding first, then Option 5 backup restore
- File hasn't expired yet but is about to → Immediately use Option 2 to save to Keep
- Have an important voice message you want to keep long-term and search later → Tinrec, convert to transcript and summary, won't disappear after 7 days
- Frequently hold online meetings and need post-meeting minutes and action items → Tinrec, desktop version records without a bot, generates summaries and action items right after the meeting
- Team needs to share meeting data → Tinrec team version, with space, seats, usage, and audit all in one place
- Don't want to spend any money and only need it once a year → Built-in phone screen recording is enough
4 things to know before use
- 7 days is a hard rule, not a reminder. Once the file is deleted, any tool can only work with what's left on your device—failure to recover is the norm.
- Keep is not a database. The 50MB threshold and 30-day limit mean it's only suitable for short-term turnover.
- Backup restore will overwrite existing conversations. Before doing so, confirm that recent important messages are saved elsewhere.
- Recording others requires consent. Regardless of the tool, informing participants before recording and complying with local regulations is basic practice.
Conclusion
The headache of expired LINE recordings is that there is no "official rescue" option—once the 7 days are up, the file is gone.
What you can do falls into two stages: for already expired files, rely on forwarding, cache, or backup and hope for the best; for files not yet expired, move them out early.
If you have voice content that will be used repeatedly—meetings, interviews, client communications—I recommend trying Tinrec. It turns voice into transcripts, summaries, and action items, stored in a searchable space, rather than gambling on a 7-day retention period.
FAQ
Q1: After a LINE recording expires, is there an official way to recover it?
No. LINE chatroom files are kept for 7 days, after which they are deleted from the server. LINE does not provide a recovery channel.
Q2: How long can LINE Keep store files?
Content under 50MB can be stored long-term; files over 50MB can only be stored for 30 days.
Q3: Does the forwarding method really work?
It has a chance of success if the file has not been completely deleted. Actual results vary depending on expiration time and device status, and are not guaranteed.
Q4: Can Tinrec help me recover expired LINE recordings?
No. Tinrec is a recording-to-text and meeting organization tool. Its purpose is to convert new or existing audio files into searchable, organizable data, not to be file recovery software.
Q5: Is the free version of Tinrec enough?
The free version provides a basic quota, suitable for trying out recording, importing, summaries, and transcription. If you have steady needs every week, consider Pro; for short-term intensive use, check the weekly pass.
Q6: What's the difference between the team version and the personal version?
The personal version stores data under your personal account; the team version is a separate team space where data belongs to the team, with additional member, role, seat, shared benefits, usage analytics, audit logs, and audio recycle bin.
