Most email services limit attachments to about 25MB, so to send large files through email you usually share a cloud link instead. Gmail and Outlook automatically upload big files to Google Drive or OneDrive and add a link. You can also compress files into a ZIP, use a transfer service like WeTransfer, or reduce the file size first. This guide covers 8 easy ways that work.
Trying to send large files through email often ends in an error, because email was never designed for big attachments.
Most services cap attachments at around 25MB, which a single video or a folder of photos can easily exceed.
The good news is there are several simple ways around this, and this guide covers each one step by step.
Why You Cannot Send Large Files Through Email Directly
Email has built-in size limits that stop very large attachments.
Gmail limits attachments to 25MB, and most other services are similar.
These limits exist to keep email fast and reliable for everyone.
When a file is too big, the answer is to share it a different way rather than attach it.
Method 1: Share a Google Drive Link in Gmail
Gmail makes it easy to send large files through email using Google Drive.
- Write your email in Gmail as usual
- Click the Google Drive icon at the bottom, or attach a file over 25MB
- Gmail uploads the file to Drive automatically
- Send the email, which now contains a shareable link
The recipient clicks the link to view or download the file.
This handles files far larger than any attachment limit.
Method 2: Share a OneDrive Link in Outlook
Outlook works the same way using Microsoft OneDrive.
- Start a new email in Outlook
- Attach your large file
- Choose to upload and share it with OneDrive when prompted
- Send the email with the link included
The recipient gets a link to open the file in OneDrive.
This is ideal if you already use Microsoft 365 or Outlook.
Method 3: Use a File Transfer Service
Services like WeTransfer are built specifically to send large files.
Upload your file on the service’s website and enter the recipient’s email.
The service emails them a download link automatically.
Many offer a free tier that handles several gigabytes at once.
Method 4: Compress Files Into a ZIP
Compressing files into a ZIP can shrink them enough to attach, and bundles many files into one.
- Select the files or folder you want to send
- Right-click and choose Compress to ZIP file, or Send to, Compressed folder
- Wait for the ZIP to be created
- Attach the ZIP to your email if it is now under the limit
Compression works best on documents, and less on photos or video that are already compressed.

You can also password-protect a ZIP to keep the files private.
Method 5: Reduce the File Size First
Sometimes shrinking the file is enough to send it normally.
Compress a PDF using a free online or built-in tool.
Resize large photos to a smaller resolution before sending.
For video, export at a lower resolution or use a shorter clip.
Method 6: Use Your Cloud Storage Directly
You can share any file straight from your cloud storage without attaching it.
Upload the file to Google Drive, OneDrive, or Dropbox.
Right-click it and choose to copy a shareable link.
Paste that link into your email, and the recipient opens the file from the cloud.
Method 7: Split a Large File Into Parts
For a very large file, you can split it into smaller pieces.
A tool like 7-Zip can split a file into parts that each fit under the limit.
Send the parts across one or more emails.
The recipient uses the same tool to join them back together.
Method 8: Use a Dedicated Large-File Email Service
Some email providers and add-ons are built to handle bigger attachments.
They store the file in the cloud and send a link behind the scenes.
This lets you attach large files as if they were normal.
Check the size limit and privacy terms before relying on one.

Which Method Should You Choose to Send Large Files Through Email?
The best method depends on the file size and who you are sending to.
For most files, sharing a Google Drive or OneDrive link is the simplest choice.
For a one-off big file to anyone, a transfer service like WeTransfer is quick.
For several documents, a ZIP keeps them together and may fit as an attachment.
Keeping Large Files Secure When You Send Them
Sharing big files safely matters as much as sending them.
Use a password-protected ZIP for sensitive files, and share the password separately.
Set cloud links to expire or require sign-in where possible.
Avoid sending private files to the wrong address by double-checking the recipient.
Common Mistakes When Sending Large Files
A few slips can cause failed or unsafe transfers.
The first is trying to attach a file well over the limit, which simply bounces back.
The second is sharing a cloud link set to public when it should be private.
The third is forgetting that the recipient may have their own inbox size limits.
Final Thoughts on How to Send Large Files Through Email
You can send large files through email easily once you stop trying to attach them directly.
Share a cloud link, use a transfer service, or compress the files to fit.
Choose the method that suits the file size and your recipient, and keep private files protected.
For details on limits, Google’s Gmail help and your email provider explain their exact rules.
Understanding Email Attachment Limits
Knowing the limits helps you plan how to send large files through email.
Gmail allows attachments up to 25MB, and files larger than that switch to a Drive link automatically.
Outlook and many other services sit around 20 to 25MB as well.
Remember the recipient’s service has limits too, so a link is often safest.
How to Send a Large Video by Email
Video is the file type most likely to be too big for email.
Upload it to Google Drive, OneDrive, or a service like WeTransfer, then share the link.
Alternatively, compress the video to a lower resolution first.
For long clips, a cloud link is almost always the best choice.
How to Send Many Photos by Email
A folder of high-resolution photos can quickly exceed the limit.
Zip the photos into one file to bundle them together.
Or upload them to a cloud album and share the link.
Google Photos and similar services make sharing whole albums simple.
Sending Large Files From a Phone
You can send large files through email from a phone just as easily.
In the Gmail app, attaching a big file adds a Drive link automatically.
The Outlook app uses OneDrive in the same way.
File transfer apps also work well for sharing big files on the go.
What Happens When a File Is Too Big
If you try to attach a file over the limit, the email will not send.
Most services show an error or offer to upload it to the cloud instead.
Accept the cloud option, and the file is shared as a link.
This is why a link is the reliable way to send anything large.
Free vs Paid File Sharing Options
Both free and paid options exist for sending large files.
Free tools like Google Drive, OneDrive, and WeTransfer cover most needs.
Paid plans add more storage, larger transfers, and extra security.
Start with the free options, and upgrade only if you send very large files often.
Making Sure the Recipient Can Open the File
Sending the file is only half the job, so make it easy to open.
Set cloud links so the recipient does not need a special account where possible.
Use common file formats that most people can open.
Add a short note explaining how to download the file.
Sending Large Files to Multiple People
Sharing a big file with a group is simplest with a cloud link.
Upload once, then send the same link to everyone.
This avoids sending huge attachments to many inboxes at once.
You can also control who can view or edit the file from the sharing settings.
Tips to Speed Up Large File Transfers
Sending big files can be slow, but a few tips help.
Use a wired or strong Wi-Fi connection for faster uploads.
Compress files first so there is less data to send.
Upload during quieter times if your connection is shared.
Keeping Track of Files You Have Shared
When you share files by link, it helps to keep track of them.
Cloud storage shows which files are shared and with whom.
Remove sharing once the recipient has the file if it is sensitive.
This keeps your shared files tidy and private.
A Quick Comparison of the Methods
To choose fast, here is how the main ways to send large files through email compare.
- Cloud link — best for most files, works in Gmail and Outlook
- Transfer service — great for one-off large files to anyone
- ZIP — bundles documents and may fit as an attachment
- Reduce file size — useful for PDFs, photos, and video
- Split into parts — for very large single files
For most people, a cloud link is the easiest and most reliable choice.
Send Any File With Confidence
You never need to be stuck by an attachment limit again.
Share a cloud link, use a transfer service, or compress your files to fit.
Pick the method that matches the file and your recipient, and keep private files protected.
With these options, you can send large files through email quickly and easily every time.
Using Google Drive to Share Large Files
Google Drive is one of the easiest ways to send large files through email.
Upload your file to Drive, then right-click it and choose Share.
Set who can access it, then copy the link into your email.
The recipient opens or downloads the file straight from Drive.
Using OneDrive to Share Large Files
OneDrive works the same way and comes built into Windows.
Upload the file, right-click it, and choose Share.
Copy the sharing link and paste it into your email.
This is ideal if you already use Microsoft 365.
Using Dropbox for Large Files
Dropbox is another reliable option for sharing big files.
Upload the file, then create a shared link from the file’s menu.
Send that link by email to anyone, even without a Dropbox account.
Its free tier suits occasional large transfers.
Compressing Video and Photos Before Sending
Reducing size is sometimes quicker than sharing a link.
Export video at 720p or 1080p instead of 4K to shrink it dramatically.
Resize photos to a web-friendly resolution before attaching them.
A smaller file may then fit within the normal email limit.
Password-Protecting Files You Send
For private files, add a password so only the right person can open them.
Create a password-protected ZIP with a tool like 7-Zip.
Send the archive, then share the password by a separate message.
This keeps your files safe even if the email is seen by someone else.
Avoiding Common File-Sending Errors
A few simple checks prevent failed transfers.
Confirm the file is fully uploaded before sending the link.
Double-check the recipient’s email address to avoid sending private files to the wrong person.
Make sure your sharing settings match how public or private the file should be.
When to Use a Link Instead of an Attachment
As a rule, use a link whenever a file is large or you are unsure of the size.
Links avoid attachment limits on both your side and the recipient’s.
They also keep your email light and quick to send.
For small documents, a normal attachment is still perfectly fine.
Never Struggle With Big Attachments Again
Sending large files by email used to be a hassle, but these methods make it simple.
Share a cloud link for most files, use a transfer service for one-off big sends, and compress when it helps.
Keep private files protected, and check the recipient can open what you send.
With this guide, you can send large files through email confidently, whatever their size.
Understanding Cloud Sharing Permissions
When you share a link to send large files through email, permissions matter.
View-only access lets the recipient open or download but not change the file.
Edit access lets them make changes, which suits shared projects.
Choose the level that fits, and restrict access for anything private.
What to Do If a Link Will Not Open
Occasionally a recipient reports that a shared link will not open.
Check that the sharing setting allows their account or anyone with the link.
Make sure the file finished uploading before you shared it.
Re-copy the link and resend it if the first one was cut off.
A Simple Plan for Sending Any Large File
To keep it easy, here is a quick plan for any big file.
- Under 25MB — attach it normally
- Over 25MB — share a Google Drive or OneDrive link
- One-off to anyone — use a transfer service
- Sensitive — use a password-protected ZIP
Follow this and you will always pick the right way to send large files through email.
Send Large Files Without Extra Software
The easiest ways to send large files through email need nothing to install.
Gmail and Outlook handle big files with Google Drive and OneDrive built in.
A web-based transfer service works straight from your browser.
So you can share large files from any computer without any setup.
Wrapping Up Your File-Sending Options
Attachment limits no longer have to slow you down.
With cloud links, transfer services, and compression, any file can reach its destination.
Choose the method that fits, keep private files protected, and send with confidence.
