How to Send Audio Files by Email: Easy Methods for Large Files

To send an audio file by email, attach it directly if it is under the size limit, for example 25 MB in Gmail. For bigger recordings, upload the file to Google Drive, OneDrive or iCloud Drive and share a link, or compress it into a smaller format like MP3 or a ZIP file. Gmail automatically turns large attachments into a Google Drive link.

Email Attachment Size Limits

• Gmail (personal): 25 MB per email. Larger files are added as a Google Drive link.
• Outlook.com: smaller limits for direct attachments; larger files can be shared through OneDrive.
• iCloud Mail (Mail Drop): large attachments can be sent as a Mail Drop link from Apple devices.
• Work or school accounts: limits are set by your organisation.

Method 1: Attach the Audio File Directly

In Gmail

1. Click Compose.
2. Click the paperclip (Attach files) icon.
3. Select your audio file, such as an MP3, M4A or WAV.
4. Add the recipient and click Send.

On a Phone

1. Open your email app and start a new email.
2. Tap the attachment icon.
3. Choose the audio file from Files, your recorder app or downloads.
4. Send the email.

Method 2: Share Large Audio Files With a Cloud Link

1. Upload the audio to Google Drive, OneDrive or iCloud Drive.
2. Right-click or tap Share on the file.
3. Set access to “Anyone with the link” or add the recipient’s email.
4. Copy the link and paste it into your email.

This method works for long recordings, podcasts and music projects that are too big to attach.

Method 3: Make the File Smaller

• Convert WAV recordings to MP3 or M4A, which are much smaller.
• Lower the bitrate for voice recordings; speech sounds fine at lower quality.
• Put several audio files into a ZIP file before attaching.
• Trim silent parts at the start and end of the recording.

Which Audio Format Should You Use?

• MP3: plays almost everywhere and keeps files small.
• M4A: good quality at small sizes, common on iPhone.
• WAV: best quality but very large, so use a cloud link.

Frequently Asked Questions

What is the maximum audio file size I can email in Gmail?

Personal Gmail accounts can send attachments up to 25 MB. Larger files are sent as a Google Drive link automatically.

Why can the recipient not open my audio file?

They may not have an app that supports the format. Send the file as MP3, which plays on almost every device.

Is sharing a Drive link safe?

Yes, if you share it only with the right people. Use “Restricted” access and add the recipient’s email for private recordings.

Final Takeaway

Attach small audio files directly, share large ones through a cloud link, and convert recordings to MP3 or M4A to keep them small. This way your audio arrives quickly and plays on any device.
