💻 How to attach files in Gmail from your computer
Attaching a file in Gmail from your computer is a quick process, but there are several methods depending on the type of file you want to include.
🧩 Method 1: Attaching from the computer directly
- Open Gmail from your browser.
- Click on the button "Redact" in the upper left corner.
- In the drafting window, you will see an icon with a paperclip 📎 at the bottom.
- Click on that clip and select "Attach files".
- A file explorer window will open on your computer.
- Choose the file you want to attach (it can be a document, a photo, a PDF, etc.).
- Click on "Open".
- Wait a few seconds while the file is uploaded to the mailbox.
When the process is finished, you will see the file name just below the subject or body of the message.
If needed, you can add more files by repeating the same procedure.
🔸 Extra tip: you can drag and drop the file directly on the Gmail window.
Gmail will automatically recognize it and add it to the mail.
☁️ Method 2: Attach files from Google Drive
If the file is too large or is already stored in your Google Drive, this is the ideal method.
- In the editor window, click on the Google Drive (a kind of triangle).
- A list of your Drive files will appear.
- Select the one you want to send.
- Click on "Insert as Drive link" o "Attach file" (depending on the type of document).
📂 Advantage: you do not need to download the file beforehand.
🌐 Recommendation: make sure the file has appropriate access permissionsor the recipient will not be able to open it.
You can easily change the permissions from the window that appears when you send it, by selecting "Anyone with the link can see".
📱 How to attach files from mobile (Android or iPhone).
Nowadays, most mail is sent from the telephone.
Gmail facilitates this process with a very intuitive interface.
📤 Send files from the Gmail application.
- Open the Gmail on your cell phone.
- Touch the button "Redact" (the pencil icon).
- At the top, write the recipient's address and the subject line.
- In the upper right corner, tap the clip 📎.
- Choose from:
- "Attach file" (to choose a file from the phone storage).
- "Insert from Drive" (to add files from your Google Drive account).
- Select the desired file and wait a few seconds while it loads.
✨ Trick: if the file is in another application (e.g., Photos, Files or Notes), you can tap the "Share" and then choose Gmail as a destination.
This will open a new email with the file already attached.
🧮 File size limits in Gmail.
One of the most frequent errors when attaching files is exceeding the maximum allowed size.
- 📎 Gmail limit: 25 MB per e-mail.
- If you exceed that size, Gmail will automatically upload the file to Google Drive and will send a download link in place.
👉 This system is very practical, as it prevents your message from being rejected by the recipient's server.
However, if you are going to send many large files (videos, photos, large PDFs)I recommend compress them before in a single ZIP or RAR archive.
You can do this easily from your computer with WinRAR o 7-Zipor even from the cell phone with free applications.
🧠 Professional tips for error-free file attachments
1. Rename the files clearly
Avoid generic names such as "document1.pdf" or "photo.jpg".
Use clear names, for example: "Budget_July2025.pdf" o "FotoEquipo_EventoMadrid.jpg".
This makes it easier for the recipient to identify the content without opening it.
Verify that the file has been completely uploaded.
Before pressing Send tosee below the message:
if you see a blue bar that is still moving, wait a few seconds.
Sending mail before the upload is complete may result in errors or incomplete files.
3. Use shared folders instead of many files.
If you need to share dozens of documents, the best thing to do is to create a folder in Google Driveand share only the folder link.
This way your mail will be cleaner and the recipient will not have to open 20 files one by one.
4. Attach carefully in formal mailings
In work environments, format and order matter.
Include the files in a logical order and mention each one in the body of the message:
"Enclosed is the monthly report and results spreadsheet."
This type of detail conveys professionalism and clarity.
