How to Send PDF Files? Choose the Right Method Based on the Situation
PDF files are widely used for contracts, invoices, manuals, and documents. However, when file sizes are large or when sharing with multiple people, you may have trouble deciding how to send them.
In conclusion, there are primarily four ways to send PDF files.
- Attach it in an email
- Send it via LINE or chat apps
- Share it using cloud storage
- Use file transfer services
The optimal method varies depending on file size, the recipient, and security requirements. Let's take a closer look at each method's characteristics.
How to Send PDF Files via Email
The most common method is attaching it to an email. If the PDF is around a few megabytes, it can usually be sent without issues.
Steps to Attach a PDF to an Email
- Open the email creation screen
- Click the attach file button
- Select the PDF file
- Enter the recipient and message, then send
However, emails have size limits. Generally, if the file exceeds about 20MB to 25MB, it may not be sent.
If the PDF file is large, consider other sharing methods.
How to Send PDF Files via LINE or Chat Apps
If you're using smartphones, you can send PDFs through LINE or business chat apps.
Simply select the file sending option from the chat screen and attach the PDF; the operation is straightforward.
However, different apps may have varying limitations on file sizes and storage durations. Furthermore, if past conversations scroll away, it may become difficult to locate the PDF.
For important documents or files that you want to store for a long time, dedicated sharing services are more suitable.
How to Share PDF Files Using Cloud Storage
Using cloud storage like Google Drive or Dropbox makes it easier to share large PDFs.
Advantages
- Can share large files
- Easy for multiple users to view
- File updates are possible
- Access permissions can be set
Disadvantages
- Account registration may be required
- If sharing settings are incorrect, third parties may gain access
- Recipient may need to perform additional actions
This method is suited for internal documents or those that require collaborative editing.
File Transfer Services Are Convenient for Sending Large PDFs
High-quality catalogs, blueprints, or photo-rich documents often result in large PDF sizes.
In such cases, using a file transfer service allows for smooth transmission.
For example, with UploadF, you can upload the PDF and simply send the generated URL to the recipient for sharing.
- Free to use
- Compatible with both PC and smartphones
- Easy upload with drag-and-drop functionality
- Password protection available
- Can choose storage duration
- Can share multiple files at once
This is particularly useful when you want to send multiple PDFs together or share files that cannot be attached to an email due to their size.
Points to Consider for Sending PDFs Safely
When sending PDFs that contain business documents or personal information, security measures are crucial.
Pre-Sending Checklist
- Verify that the recipient's address is correct
- Check that no unnecessary personal information is included
- Confirm the sharing scope
- Set a password if necessary
- Review public link settings
Particularly for contracts or estimates, be cautious of information leaks due to incorrect transmissions.
What to Do If You Can't Send PDFs
If you can’t send the PDF, check the following items:
- Is the file size too large?
- Is the PDF file corrupted?
- Has the email service’s size limit been reached?
- Is the recipient able to receive attachments?
- Is the network environment stable?
If size is the issue, you can often resolve this by compressing the PDF or using a file transfer service.
Conclusion
Methods for sending PDFs include email attachment, chat apps like LINE, cloud storage, and file transfer services.
For small PDFs, email attachment is usually sufficient, but for large files or when sharing multiple files, dedicated services are more convenient.
With UploadF, you can easily share files by uploading the PDF and sending the shareable URL. With options for password protection and setting storage duration, it can be used for both business and personal purposes.
When sending PDFs, consider not just the file size but also security, and choose the method that fits your needs.
