How to attach a file to an email

Sending an email is easy, but attaching a document, picture or other file can be confusing if you have never done it before. You may need to send your CV to an employer, submit an assignment, share a PDF document or send pictures to someone.

The process is simple once you know where to find the attachment option.

Whether you use Gmail, Outlook, an Android phone or an iPhone, this guide explains how to attach a file to an email, send multiple attachments and fix common problems.

What Does It Mean to Attach a File to an Email?

Attaching a file to an email means adding a document, picture, video or another file to a message before sending it.

Instead of typing all the information into the email itself, you can send the file alongside your message.

For example, if an employer asks you to email your CV, you can write a short message introducing yourself and attach your CV as a PDF or Word document.

The recipient will receive your email with the attached file and can open or download it.

Common files you can attach include:

• PDF documents
• Microsoft Word documents
• Excel spreadsheets
• PowerPoint presentations
• Pictures and photographs
• Videos
• Audio files
• ZIP files

The types of files you can send depend on the email service and its attachment restrictions.

How to Attach a PDF Document to an Email

PDF files are commonly used when sending CVs, certificates, assignments, application forms and official documents.

If your PDF is already saved on your device, you can attach it using the same steps described earlier.

For example, to attach a PDF through Gmail on a computer:

1. Open Gmail.
2. Click Compose.
3. Enter the recipient’s address.
4. Add your subject and message.
5. Click the paperclip icon.
6. Open the folder containing your PDF.
7. Select the PDF document.
8. Click Open.
9. Wait for it to upload.
10. Click Send.

Before sending, check that you selected the correct PDF.

If you have several documents with similar names, open the file first to confirm its contents.

You should also give the file a clear name.

For example:

Jane_Smith_CV.pdf

This makes it easier for the recipient to identify your document.

How to Attach Multiple Files to an Email

Sometimes, one attachment is not enough.

You may need to send your CV, cover letter, certificates and other supporting documents in one email.

Most email services allow you to attach several files to a single message.

On a Computer

1. Open your email account.
2. Click Compose or New mail.
3. Enter the recipient’s address.
4. Write your subject and message.
5. Click the attachment icon.
6. Open the folder containing your documents.
7. Select the files you want to send.

On Windows, hold down the Ctrl key while clicking each file.

On a Mac, hold down the Command key while selecting multiple files.

8. Click Open.
9. Wait for all the files to upload.
10. Check that every attachment appears before sending.

On a Smartphone

The process may differ depending on your phone and email application.

Generally:

1. Open your email application.
2. Start a new message.
3. Enter the recipient’s details.
4. Tap the attachment icon.
5. Browse your files.
6. Select the documents you want to include.
7. Confirm that all attachments have been added.
8. Send the email.

If your application does not allow you to select several files at once, attach them individually.

How to Attach Pictures to an Email

You can send photographs and other images through email by attaching them to your message.

This is useful when sharing identification documents, screenshots, product pictures, certificates or personal photographs.

To attach a picture:

1. Open your email application.
2. Start a new message.
3. Enter the recipient’s address.
4. Write your message.
5. Click or tap the attachment icon.
6. Select the picture from your device.
7. Wait for it to upload.
8. Send the email.

Some email applications also allow you to drag a picture directly into the message window on a computer.

Attaching an Image vs Inserting an Image

These two options are different.

Attaching an image adds the picture as a separate file that the recipient can open or download.

Inserting an image places the picture directly inside the body of your email.

If you want someone to download and save the original picture, attaching it is usually the more suitable option.

How to Attach a File From Google Drive

You do not always need to download a document to your computer before sending it through Gmail.

If the file is already saved in Google Drive, you can share it directly from your email.

Follow these steps:

1. Open Gmail.
2. Click Compose.
3. Enter the recipient’s email address.
4. Write your subject and message.
5. Click the Google Drive icon at the bottom of the message window.
6. Locate the document you want to share.
7. Select the file.
8. Click Insert.
9. Review the sharing permissions.
10. Send the email.

When you share a Google Drive file, the recipient may receive a link rather than a traditional file attachment.

Check the access settings before sending. If the recipient does not have permission to open the document, they may be unable to view it.

Choose the appropriate access option, such as allowing the recipient to view the file.

How to Send Large Files Through Email

Sometimes, you may try attaching a document or video and discover that it is too large to send.

This happens because email providers place limits on attachment sizes.

For example, personal Gmail accounts have a total attachment sending limit of 25 MB per email. If the total attachment size exceeds this limit, Gmail automatically adds a Google Drive link instead.

Other email services have their own restrictions.

If your file is too large, consider these options:

1. Use Google Drive

Upload the document or video to Google Drive and share its link through email.

Make sure the recipient has permission to access it.

2. Use OneDrive

If you use Outlook, you can upload your document to OneDrive and share it through a link.

This is useful when sending large documents or files that are difficult to attach directly.

3. Compress the File

You can reduce the size of some files by compressing them into a ZIP folder.

This may help when sending several documents together.

However, compression does not always reduce file sizes significantly, especially for pictures and videos that are already compressed.

4. Reduce the File Size

If you are sending a PDF, you may be able to use a PDF compression tool to reduce its size.

For pictures, reducing their resolution may also help.

Always check that the file remains clear and readable after compression.

Common Problems When Attaching a File to an Email

You may occasionally experience problems when trying to attach a document.

Here are some common issues and how to resolve them.

1. The Attachment Icon Is Not Working

If you click the attachment icon and nothing happens, try refreshing your email page.

You can also close and reopen your browser or application.

If the problem continues, check your internet connection.

2. The File Is Not Uploading

A weak internet connection may interrupt the upload process.

Check that your device is connected to the internet and try attaching the file again.

If the document is large, allow enough time for the upload to finish.

3. The File Is Too Large

Your email provider may reject an attachment that exceeds its size limit.

Try compressing the document or sharing it through Google Drive or OneDrive.

4. The File Type Is Not Supported

Some email services block certain file types for security reasons.

If your attachment is rejected, check whether the file type is supported.

Do not rename a restricted file extension simply to bypass the security restriction.

Use a safe, supported format where possible.

5. You Attached the Wrong Document

If you notice that you selected the wrong file before sending the email, remove the attachment and choose the correct one.

If you have already sent the message, you may need to send another email with the correct document and explain the mistake.

6. The Recipient Cannot Open the File

The recipient may not have the application required to open your document.

For example, some files require specific software.

If possible, send documents in commonly supported formats such as PDF.

If you are sharing a cloud link, check that the recipient has permission to open it.

Things to Check Before Sending an Email Attachment

Before clicking Send, take a moment to review your message.

A few simple checks can prevent unnecessary mistakes.

• Check the recipient’s address: Make sure the email is going to the correct person.
• Check the attachment: Confirm that you selected the right document.
• Check the file name: Use a clear and professional file name.
• Check the subject: Make sure it explains what the email contains.
• Check the message: Read through it to correct spelling mistakes.
• Check the upload: Ensure the attachment has finished uploading.
• Check the file format: Make sure the recipient can open it.
• Check the sharing permissions: If you sent a cloud link, confirm that the recipient can access it.

If you are sending sensitive documents, double-check the recipient’s address before sending. An email containing personal information or official documents should not be sent to an unintended person.
