To send large files for free, upload them to a cloud drive you already have, such as Google Drive (15 GB free), OneDrive (5 GB free) or iCloud Drive, and share a link instead of attaching the file. Gmail does this automatically for anything over its 25 MB attachment limit. On iPhone and Mac, Apple Mail’s Mail Drop sends attachments up to 5 GB without using your iCloud storage. For a quick one-off transfer without an account, WeTransfer’s free plan handles up to 3 GB. And if the other person is next to you, AirDrop or Quick Share is fastest of all. This guide compares every option and shows how to share safely.
Why won’t my email send a big file?
Email was never built for large files. A personal Gmail account can send up to 25 MB of attachments per message, and other email providers have similar or lower limits. Videos, photo albums, design files and long presentations easily go past that. The fix is to send a link to the file instead of the file itself.
The best free ways to send large files
| Method | Free limit | Best for | Account needed? |
|---|---|---|---|
| Google Drive | 15 GB storage (shared with Gmail and Photos) | Gmail users, sharing with anyone | Yes (Google Account) |
| OneDrive | 5 GB storage | Outlook and Windows users | Yes (Microsoft account) |
| iCloud Mail Drop | Up to 5 GB per email; links last 30 days | iPhone, iPad and Mac users | Yes (Apple Account) |
| WeTransfer (free) | 3 GB per transfer, 10 transfers a month; links expire after 3 days | Quick one-off transfers | No to send |
| AirDrop | No set size limit | Apple devices nearby | No |
| Quick Share | No set size limit | Android phones and Windows PCs nearby | No |
Free limits change from time to time, so check the service before you send something important. To compare storage plans in more detail, see Google Drive vs iCloud vs OneDrive.
How do you send a large file with Google Drive?
- Go to drive.google.com or open the Google Drive app and tap New or the plus button, then Upload.
- When the upload finishes, right-click the file (or tap the three dots) and choose Share.
- Type the person’s email address to share it with them only, or change General access to “Anyone with the link” if they do not use Google.
- Click Copy link or Send.
In Gmail, you can also click the Google Drive icon at the bottom of a new message to insert a file from Drive. If you attach a file larger than 25 MB, Gmail automatically uploads it to Drive and adds a link.
How do you send a large file with OneDrive or Outlook?
- Upload the file to OneDrive at onedrive.com or in the OneDrive folder on your Windows PC.
- Select the file and click Share.
- Choose who can open it, then copy the link or email it directly.
When you attach a large file in Outlook, it usually offers to upload it to OneDrive and share it as a link.
How do you use Mail Drop on iPhone or Mac?
- In the Mail app, write a new email and attach a large file, photo or video.
- When you tap or click Send, Mail asks whether to use Mail Drop if the attachment is too large. Choose Use Mail Drop.
- The recipient gets a download link that works for 30 days.
Apple says Mail Drop attachments can be up to 5 GB and do not count against your iCloud storage.
How do you send a file without an account?
WeTransfer lets you send files without signing up. Go to wetransfer.com, add your files, enter your email (and the recipient’s, or get a link) and click Transfer. The free plan currently allows up to 3 GB per transfer and 10 transfers a month, and links expire after three days, so tell the person to download it soon. It is meant for personal use; businesses need a paid plan.
How do you send files to someone nearby?
- iPhone, iPad and Mac: use AirDrop. Tap Share on the file, choose AirDrop and select the person’s device. Both devices need Wi-Fi and Bluetooth turned on.
- Android and Windows: use Quick Share. Tap Share, choose Quick Share and pick the nearby device. Windows PCs can use the Quick Share app.
- Between iPhone and Android: use a cloud link or a USB cable with a computer, because AirDrop and Quick Share only work within their own systems for most devices.
Can you make the file smaller first?
Often, yes, and it makes any method faster:
- Zip folders: on Windows, right-click a folder and choose Compress to ZIP file. On a Mac, right-click and choose Compress. This bundles many files into one, though photos and videos shrink only a little.
- Compress images: resize photos before sending. Our free Image Toolkit does it in your browser, and our guide on compressing images without losing quality explains the settings.
- Lower video resolution: a 4K video exported in 1080p is far smaller and still looks good on most screens.
- Convert PDFs to images only if needed: our PDF to JPG converter can help when a form asks for images.
How do you share large files safely?
- Share with specific people instead of “anyone with the link” when the file is private.
- Turn off access later. After the person downloads the file, remove sharing or delete the file from your cloud.
- Set an expiration date if your service offers it.
- Do not send sensitive documents such as tax forms or ID scans through random free transfer sites. Use a trusted cloud account with two-factor authentication.
- Beware of fake “file shared with you” emails. Scammers copy these notifications to steal passwords. If you were not expecting a file, check with the sender another way. See how to spot a phishing email.

Frequently asked questions
What is the largest file I can email?
About 25 MB with Gmail and similar limits elsewhere. Anything larger should be sent as a cloud link, which Gmail and Outlook can create for you.
What is the best free way to send a 10 GB file?
Upload it to Google Drive, which offers 15 GB of free storage, and share a link. Make sure you have enough free space first.
Does the recipient need an account to download?
Usually not. If you share a Google Drive or OneDrive link with “anyone with the link” access, or use Mail Drop or WeTransfer, they can download without signing in.
Why is my upload so slow?
Upload speeds are often much lower than download speeds. Use Wi-Fi rather than mobile data, and check your connection with our free internet speed test.
Pick the simplest option
For most people, the easiest choice is the cloud drive tied to the email you already use: Google Drive for Gmail, OneDrive for Outlook and Mail Drop for Apple Mail. Use WeTransfer for quick one-offs and AirDrop or Quick Share when the other person is in the same room.
