Email has a file size limit, and most large files hit it
Most email providers cap attachments at 20 to 25 megabytes per message. A video file, a folder of photos, or a design project file will almost always exceed that. When you try to send something too large, your email either bounces back undelivered or sits in your outbox indefinitely. The solution is not to fight the limit — it is to use a file-sharing service instead, which takes seconds to set up and works reliably.
The fastest route depends on what you already have access to. If you use Gmail, OneDrive, Google Drive, or Dropbox, you can send a shareable link in seconds without uploading anywhere new. If you do not have any of those, Dropbox and WeTransfer both work without an account. Pick whichever method matches what you already use, and you will be done before you would have finished troubleshooting why your email failed.
Key Takeaways
- Email attachments are limited to 20 to 25 megabytes, so videos, photo folders, and large project files will not go through as attachments.
- Gmail, OneDrive, Google Drive, and Dropbox let you share files by link from services you may already have, with no extra upload needed.
- WeTransfer and Dropbox Basic both work without an account and let you send files up to 2 gigabytes in a single transfer.
- A shareable link is more secure than an attachment because the recipient cannot accidentally forward your file to someone else.
- The recipient does not need to create an account or install software to download a file you share by link.
Using Gmail to share files without uploading twice
If you use Gmail, you can attach a file from Google Drive without uploading it separately. Open a new email in Gmail, click the attachment icon (a paperclip), and select "Google Drive" from the menu. Choose the file you want to send, and Gmail will insert a link instead of attaching the file itself. The recipient clicks the link to view or download it.
If the file is not already in your Google Drive, you can upload it there first. Go to drive.google.com, click "New," select "File upload," and choose your file. Once it is uploaded, go back to your email and follow the steps above. This method works for files of any size because you are sharing a link, not sending an attachment.
Sharing from OneDrive or Dropbox if you already use them
OneDrive and Dropbox work the same way as Google Drive. If your file is already in OneDrive (Microsoft's cloud storage), right-click it and select "Share." Choose who can access it, copy the link, and paste it into your email. The recipient gets a link they can click to view or download the file. Dropbox works identically — right-click the file, select "Share," and copy the link into your message.
Both services let you control whether the recipient can edit the file or only view it. You can also set an expiration date so the link stops working after a certain number of days. This is useful if you are sending sensitive information and want to make sure the file is not accessible forever.
WeTransfer for one-time file sharing without an account
WeTransfer is a free service that lets you send files up to 2 gigabytes without creating an account. Go to wetransfer.com, click "Add your files," and select the file from your computer. Type in the recipient's email address, add a message if you want, and click "Transfer." WeTransfer uploads the file and emails the recipient a download link. They have 7 days to download it before the link expires.
WeTransfer is useful when you do not have a cloud storage account and do not want to set one up. The recipient does not need an account either — they just click the link in the email and download the file. If you send files this way regularly, you can create a free WeTransfer account to keep a history of your transfers, but it is not required.
Dropbox Basic for larger files and repeated use
Dropbox Basic is free and lets you send files up to 2 gigabytes, the same as WeTransfer. The difference is that Dropbox stores your files permanently so you can access them later, while WeTransfer is designed for one-time transfers. If you plan to send large files more than once, Dropbox is worth setting up because you will not have to re-upload the same file each time.
Go to dropbox.com, click "Sign up," and create an account with your email. Download the Dropbox app to your computer or use the web version. Drag your file into Dropbox, right-click it, select "Share," and copy the link into your email. The recipient clicks the link to download. You get 2 gigabytes of free storage, which is enough for several large files.
What to do if the recipient cannot download the file
If the recipient says the link is broken or they cannot access it, the most common cause is that you shared the file but did not give them permission to view it. In Google Drive, OneDrive, and Dropbox, double-check the sharing settings and make sure "Anyone with the link can view" or "Anyone with the link can download" is selected. If it says "Restricted," only people you specifically invited can access it.
The second most common issue is that the link expired. WeTransfer links expire after 7 days, and some services let you set custom expiration dates. If the recipient waited too long, you will need to send the file again. For files you share regularly, use Dropbox or Google Drive instead, where the link stays active as long as you want it to.

Frequently Asked Questions
Can I email a file larger than 25 megabytes as an attachment?
No. Most email providers reject attachments larger than 20 to 25 megabytes. The email will either bounce back immediately or sit in your outbox indefinitely. Using a file-sharing service instead takes the same amount of time and works reliably for files of any size.
Is it safe to share files by link?
Yes, as long as you use the sharing settings correctly. Make sure you choose "Anyone with the link can view" or "Anyone with the link can download" so the recipient can actually access it. If you want to restrict access to specific people, select "Restricted" and invite them by email. A shared link is actually more secure than an email attachment because the recipient cannot accidentally forward your file to someone else.
What happens to the file after the recipient downloads it?
The file stays in your cloud storage account. The recipient has their own copy on their computer. If you delete the file from your account, the recipient keeps the copy they downloaded, but the link stops working for anyone else who tries to access it later.
Do I need to compress a file before sharing it by link?
No. File-sharing services handle large files without compression. Compressing (zipping) a file makes it smaller but takes extra time and is unnecessary when you are using a service designed for large transfers. Just upload the file as is.
Can I share a folder instead of a single file?
Yes. Google Drive, OneDrive, and Dropbox all let you share entire folders by link. Right-click the folder, select "Share," and follow the same steps as sharing a single file. The recipient can download the whole folder at once or individual files from inside it.
