The fastest way depends on what you have and where the document needs to go

Once you have scanned a document into your computer, sending it takes a few minutes. The easiest route for most people is email — you attach the scanned file and send it like any other message. If the file is too large for email, you can use a file-sharing service like Google Drive or Dropbox instead. For documents that need a signature or official stamp, some services let you send them directly to a printer or fax machine without saving them to your computer first.

The method you choose depends on three things: whether the recipient needs the file right away, whether they need it in a specific format, and how large the file is. A single-page scan is usually small enough for email. A 50-page document or a high-resolution color scan might need a sharing service instead.

Key Takeaways

  • Email works for most documents under 25 MB, which covers most scans of a few pages.
  • Google Drive, Dropbox, or OneDrive let you share larger files or give someone access to a folder instead of sending individual attachments.
  • Your scanner's software may have a "send to email" button that skips saving the file first and goes straight to your email program.
  • If the recipient needs a printed copy, some scanners can send directly to a printer or fax without you saving the file.
  • PDF is the safest format for sharing because it looks the same on any device and cannot be accidentally edited.

Sending a scanned document by email

Open your email program — Gmail, Outlook, Apple Mail, or whatever you use — and start a new message. Type the recipient's email address, a subject line, and your message. Then look for an "Attach" button, usually shown as a paperclip icon. Click it and navigate to the folder where your scanner saved the file. Select the file and click "Open" or "Attach".

Most email services will accept files up to 25 MB. A typical scan of a few pages is 1 to 5 MB, so you will have room. If you scanned in color at high resolution, check the file size before sending — right-click the file and look at "Properties" on Windows or "Get Info" on Mac. If it is larger than 20 MB, use a file-sharing service instead.

Once the file is attached, click "Send". The recipient will see it as a read link in their inbox. They can open it, save it, or print it from there.

Using your scanner's built-in email button

Many scanners have a button on the device itself labeled "Email" or "Send". If yours does, you can skip saving the file to your computer. Place the document on the scanner, press the Email button, and the scanner will ask you to choose a recipient from a list you set up earlier. The scanner sends the file directly to that person's email address.

To set this up, open your scanner's software on your computer — usually called something like "Canon Scan" or "HP Scan" — and look for settings or preferences. Find the section for email recipients and add the email addresses you use most often. Save the settings, and the next time you press the Email button on the scanner, those names will appear on the scanner's screen.

This method is faster if you scan documents regularly and send them to the same people. It also means the file never sits on your computer, which can be useful if you are scanning sensitive documents.

Sharing larger files with Google Drive, Dropbox, or OneDrive

If your scanned file is larger than 20 MB, or if you want to share a folder of multiple scans with someone, use a cloud storage service. Google Drive, Dropbox, and OneDrive all work the same way: you upload the file to your account, then share a link with the recipient. They can view, read, or print the file without needing their own account.

To share a file on Google Drive, open drive.google.com, click "New" on the left, and select "File upload". Choose your scanned document and wait for it to upload. Right-click the file, select "Share", and type the recipient's email address. Choose whether they can view only, comment, or edit. Click "Share" and Google will send them an email with a link.

Dropbox and OneDrive work similarly. In Dropbox, right-click the file and select "Share". In OneDrive, click the file and select "Share" at the top. Both will give you a link to send to the recipient, or you can type their email address and they will get an invitation.

The advantage of these services is that you can update the file later and the recipient will see the new version without you sending another email. You can also set an expiration date on the link so it stops working after a certain number of days.

Sending directly to a printer or fax

Some scanners can send a scanned document directly to a printer or fax machine without saving it to your computer first. This is useful if you need to send an official document to a government office or business that still uses fax, or if you want to print copies when ready.

On the scanner's software, look for a "Send to Printer" or "Fax" option. You will need to set up the printer or fax number in the scanner's settings first. Once you do, you can place a document on the scanner, select the destination from the scanner's screen or software, and the file goes straight there.

Faxing through your scanner requires either a fax modem in your computer or a service like eFax or MyFax. If you do not have either, you can scan the document and upload it to an online fax service, which will send it for you. These services usually charge per page.

Choosing the right file format for sharing

When you scan a document, your scanner software saves it as a file — usually PDF, JPEG, or TIFF. PDF is the best choice for sharing because it looks the same on any computer, phone, or tablet, and the recipient cannot accidentally change it. Most scanners default to PDF, so you probably do not need to change anything.

JPEG is a photo format that works well for single images but can look blurry if you scan multiple pages. TIFF is a high-quality format that takes up more space and is less common on phones and tablets. If your scanner asks you to choose a format, stick with PDF unless you have a specific reason not to.

If you need to edit the document after scanning — for example, to crop out a blank area or add a signature — you can open the PDF in free software like Preview on Mac or Paint on Windows, make the changes, and save it again before sending.

What to do if the file is too large to send

If your scanned file is larger than your email service allows, you have three options: compress the file, use a file-sharing service, or rescan at a lower resolution.

To compress a PDF on Windows, right-click the file, select "Send to", and choose "Compressed (zipped) folder". On Mac, right-click and select "Compress". This reduces the file size, though it may make the image slightly less clear. Most email services will accept a compressed file that the original would have rejected.

File-sharing services like Google Drive do not have the same size limits as email, so uploading a large file there and sharing a link is usually faster. If you need to rescan, open your scanner's software and look for resolution or quality settings. Scanning at 200 DPI instead of 300 DPI, or in black and white instead of color, will make the file smaller without making it unreadable for most purposes.

Frequently Asked Questions

Can I scan and send a document from my phone instead of a computer?

Yes. Most phones have a built-in scanner app — "Notes" on iPhone, "Google Lens" on Android. Open the app, take a photo of the document, and the app will straighten it and save it as a PDF. You can then email it or share it through Google Drive just like a file from a computer scanner.

What if the recipient says they did not receive my email with the attachment?

Check that the file actually attached — look for a paperclip icon or the file name in the email before you send. If it did attach, the file may have been caught by their spam filter or blocked by their company's email system. Try uploading the file to Google Drive and sending them a link instead, which sometimes gets through when attachments do not.

Do I need to convert the PDF to another format before sending?

No. PDF works on every device and email service. If someone asks for a different format like Word or Excel, you can use online conversion tools like Smallpdf or ILovePDF to change it, but PDF is the safest choice for most situations.

Can I password-protect a scanned document before sending it?

Yes, but it depends on your software. Some PDF readers like Adobe Acrobat let you add a password so the recipient has to enter it to open the file. Google Drive also lets you set permissions so only people you invite can view the file. For sensitive documents, using Google Drive with view-only access is usually simpler than password-protecting a PDF.

How long does it take to send a scanned document?

Email usually delivers within seconds to a few minutes. File-sharing services like Google Drive send the link when ready, but the recipient may take time to read or view the file. Fax can take a few minutes depending on the number of pages and the quality of the connection.
