Learn About Gmail Attachments and How They Work
Understanding Gmail Attachments: The Basics
Gmail attachments are files that you can send and receive alongside your email messages. When you compose an email in Gmail, you have the option to include documents, photos, videos, spreadsheets, or many other types of files. The person receiving your email will see these files and can view or save them to their own computer or device.

Attachments work by being uploaded from your device to Google's servers when you send an email. The file travels with your email message to the recipient's inbox. Gmail stores these files temporarily while they are being transmitted. Once the email reaches the recipient, they can interact with the attachment in several ways: open it directly in Gmail using Google's preview tools, save it to their computer, or save it to Google Drive for cloud storage.
The Gmail attachment system has been designed to handle a wide range of file types. You can attach almost any kind of file, from common formats like PDF and Word documents to image files like JPG and PNG, to audio and video files. Gmail even allows you to attach compressed files (ZIP folders) that contain multiple files bundled together.
One important distinction exists between sending attachments and using Google Drive integration. While attachments are files sent directly with your email, Gmail also allows you to share files stored in Google Drive. This option appears as a separate feature when composing emails and works differently from traditional attachments—it creates a link rather than sending the actual file with the message.
Practical Takeaway: Attachments are files sent directly with your email message. Before sending attachments, consider whether the file size is appropriate and whether the recipient's email system can handle the file type you're sending. Testing your attachment process with a colleague before sending important files to external contacts is a worthwhile precaution.
File Size Limits and Restrictions
Gmail has specific limits on how large files can be when you attach them to emails. The maximum file size for a single attachment in Gmail is 25 megabytes (MB). This limit applies to each individual file you attach. If you want to send multiple attachments, each file must be under 25 MB, though you can send several files in one email as long as each one meets the size requirement.

Understanding file sizes helps you determine what types of files you can attach. A typical Word document might be 500 kilobytes (KB) to 2 MB. A single photo from a smartphone camera is often 2 to 5 MB. A short video clip can easily exceed 25 MB. High-resolution photos or professional graphics files may also surpass the limit. Before attaching any file, you can check its size by right-clicking the file on your computer and selecting "Properties" (on Windows) or "Get Info" (on Mac).
When you try to attach a file larger than 25 MB, Gmail will prevent you from sending it and will display an error message. This protection exists to prevent email systems from becoming overloaded and to ensure emails transmit reliably. The restriction also protects recipients who may have email storage limits or slower internet connections.
If you need to send files that exceed the 25 MB limit, Gmail offers alternatives. You can compress the file to make it smaller, split a large file into multiple smaller pieces, or use Google Drive to share the file instead. Google Drive allows you to store files up to 5 TB in size (though free accounts have a 15 GB storage limit) and share them with others through links rather than as direct attachments.
Different email providers have different size limits. Outlook has a 20 MB limit, Yahoo Mail allows up to 25 MB, and some business email systems may have stricter limits. When sending to people using different email providers, it's helpful to stay well below size limits to ensure compatibility across systems.
Practical Takeaway: Keep individual attachment files under 25 MB to avoid sending errors. For files larger than this limit, consider compressing them first or using Google Drive sharing instead. When corresponding with people who use different email providers, check their specific size limitations before sending large files.
How to Send Attachments in Gmail
Sending attachments in Gmail is straightforward. To begin, open Gmail and click the "Compose" button to create a new email. This opens the compose window where you can type your message. At the bottom of the compose window, you'll see several icons. The paperclip icon represents the attachment function. Click on this paperclip to begin the process of attaching a file.
When you click the paperclip icon, a menu appears with two main options. The first option allows you to select files from your computer. When you choose this option, a file browser window opens that shows the folders and files on your device. Navigate to the location where your file is stored, select the file you want, and click "Open." Gmail will then upload that file and add it to your email. You can attach multiple files by repeating this process.
The second option in the attachment menu may allow you to select files from Google Drive or other cloud storage services if you've set up those integrations. This is useful if the file you want to share is already stored in the cloud rather than on your local device.
As you add attachments, they appear in the compose window with their filenames displayed. You can see the size of each file listed next to the filename. If you need to remove an attachment before sending, you can click the X next to the filename to delete it. Before clicking "Send," take a moment to verify that all the attachments you intended to include are present and that the email message is complete.
Mobile devices (phones and tablets) handle attachments slightly differently. In the Gmail app on Android or iPhone, you can tap the paperclip icon during email composition, though the specific steps may vary depending on your device and Gmail app version. The mobile interface allows you to select photos from your camera roll or other files stored on your device.
Practical Takeaway: Use the paperclip icon to add attachments when composing emails in Gmail. Check that files are listed before sending, verify they don't exceed size limits, and consider whether the recipient's email system can handle the file types you're sending. Always verify attachments are included before clicking "Send."
Receiving and Managing Attachments
When someone sends you an email with attachments in Gmail, the attachments appear below the email message body. You'll see a paperclip icon next to the sender's name in your inbox, indicating the email contains one or more attached files. The attachment section shows the filenames and file sizes, allowing you to see what was sent before opening the files.
Gmail provides several options for working with received attachments. You can preview many file types directly within Gmail without having to save them to your computer first. For images, PDFs, and text documents, Gmail shows a preview pane where you can view the file content. This preview feature helps you verify that you received the correct file before taking further action.
If you want to keep a copy of an attachment on your computer, you can save it by clicking the "Download" button next to the filename. This stores the file in your computer's "Downloads" folder or another location you specify. Alternatively, you can right-click on the attachment and select "Save as" to choose a specific folder where you want to store it.
Gmail also allows you to save attachments directly to Google Drive. This feature is useful if you prefer to keep files in cloud storage rather than on your local device. By selecting "Save to Drive" next to an attachment, Gmail creates a copy of the file in your Google Drive account. You can then access this file from any device with internet access.
Managing attachments helps keep your email account organized and your device storage manageable. Large attachments can accumulate over time and consume significant storage space. Periodically reviewing emails with large attachments and determining whether you still need them prevents storage problems. Gmail's search function allows you to find emails with attachments by searching for "has:attachment" in the search box.
Practical Takeaway: When receiving attachments, preview them in Gmail first to verify content before saving. Save important attachments to Google Drive or your computer's organized folder system. Regularly clean up old attachments you no longer need to maintain storage space and email organization.
Security Considerations for Attachments
Attachments present security considerations that both senders and recipients should understand. Gmail includes built-in protections to scan attachments for viruses and malware. When you receive an email with an attachment,
