What Causes LINE to Not Send Large Files?
LINE is a convenient app for sending files, but sometimes it generates an error when trying to send large videos, PDFs, or compressed files.
In particular, videos, high-quality photos, and business-related document files tend to have large sizes, leading to failures in sending.
LINE has restrictions on the types and sizes of files that can be sent, and there are also length restrictions for videos. Additionally, the condition of the device or app may prevent normal transmission.※Specifications may change.
Checklist to Confirm First
- Check if the file size is excessively large.
- Check if the video length is too long.
- Check if it is an unsupported file format.
- Update the LINE app to the latest version.
- Restart your smartphone or PC.
- Try changing the destination chat room.
- Confirm if the same issue occurs when sending a different file.
Countermeasure 1: Reduce File Size
The most common cause is the file size.
For videos, lowering the resolution, trimming unnecessary parts, or using compression software may allow sending.
For photos, sending at standard quality instead of original quality can reduce size.
However, compressing may lower the quality or fidelity. If you want to share important documents or high-quality videos, consider alternative methods.
Countermeasure 2: Change File Format
Some special file formats may not be sent correctly via LINE.
For example, proprietary formats from editing software or specific data files may not be openable by the recipient.
In such cases, converting to common formats like PDF or ZIP before sending may resolve the issue.
Countermeasure 3: Use File Sharing Services
When sending large files, using a file sharing service is the most reliable method.
You only need to upload the file and send the generated URL via LINE, so there’s no need to worry about LINE's size or video restrictions.
This is especially useful for sharing videos, PDFs, ZIP files, and multiple files.
For example, using UploadF, you can use both PC and smartphone to easily upload files with drag and drop.
It also supports specifying the storage period and setting passwords, making it useful for sharing work documents and private files.
Countermeasure 4: Send Multiple Files Together
When you have a large number of photos or documents, sending them one by one can be burdensome to manage.
Grouping them into a ZIP file or using a file uploader for batch sharing is efficient.
UploadF allows you to upload up to 100 files at once, making it convenient for sharing a large number of images or documents.
Utilize Convenient Features for Image Sharing
If you want to edit images before sharing, choosing a service with image editing features is helpful.
UploadF offers features such as the following.
- Mosaic processing
- Image cropping
- Resizing
- Rotation and flipping
- Background transparency
- Adding watermarks
- OCR text recognition
- AI image learning prevention processing
These features are also helpful when sharing images that contain personal information or for social media posts.
What to Avoid When You Can't Send on LINE
Repeatedly resending the same file whenever a transmission error occurs only wastes time.
Especially when sharing videos over several hundred MB or large amounts of photos, it’s more efficient to use a file sharing service from the outset.
If it can't be sent after several attempts, switching to a URL sharing method rather than using LINE often resolves the issue more quickly.
Conclusion
The causes of not being able to send large files on LINE include size limitations, video length, and file formats, among others.
For smaller sizes, compression or format changes may resolve the issue, but if you want to securely send large videos or documents, using a file sharing service is recommended.
UploadF can be used for free, and it supports password settings and storage period specifications, making it a practical tool for sharing large files that can’t be sent on LINE.
