The fastest way depends on what you're sending and who needs it

Most email services cap attachments at 25 MB, so anything larger needs a different route. The best choice depends on whether the person receiving the file has a specific service already, how soon they need it, and whether you want a link that expires or stays active. Cloud storage services like Google Drive, Dropbox, and OneDrive let you upload once and share a link instead of sending the file itself — the recipient downloads from the link whenever they're ready. File transfer sites like WeTransfer and Tresorit work similarly but delete files after a set time, which is useful if you don't want the file sitting on someone's account permanently.

For very large files — video projects, design files, raw footage — dedicated transfer services often handle them better than cloud storage because they're built for one-time sharing rather than ongoing collaboration. The trade-off is that most free versions expire the link after a few days, while cloud storage keeps files indefinitely unless you delete them.

Key Takeaways

  • Email attachments max out around 25 MB, so files larger than that need cloud storage or a file transfer service instead.
  • Google Drive, Dropbox, and OneDrive let you upload a file once and share a link that stays active as long as you want it to.
  • WeTransfer and similar services work faster for one-time sharing but delete files after days or weeks, which protects privacy if you don't want the file stored permanently.
  • You control who can access the file by choosing between a public link, a link that requires a password, or sharing only with specific email addresses.

Using Google Drive, Dropbox, or OneDrive for files you want to keep accessible

These services store the file on their servers and give you a shareable link. You upload the file once, then send the link to as many people as you want — they don't need to be your contacts, and the file doesn't take up their email storage. To share on Google Drive, right-click the file, select "Share," and choose whether the link is viewable by anyone with the link, restricted to specific people, or password-protected. Dropbox and OneDrive work the same way: upload, right-click, share, and set permissions.

The main advantage is that the link stays active indefinitely. If someone loses the file or needs it again months later, they can read it again from the same link. The file also stays in your account, so you can update it if needed — anyone with the link sees the newest version. This works well for documents, presentations, and files you might need to share again later.

File size limits are generous: Google Drive allows 5 TB per file, Dropbox allows 2 GB per file on free accounts (unlimited on paid), and OneDrive allows 250 GB per file. For most people, these limits won't matter.

Using WeTransfer or Tresorit for temporary one-time sharing

These services are built for sending files that don't need to stick around. You upload the file, enter the recipient's email address, and the service sends them a read link. The file deletes automatically after a few days — WeTransfer deletes after 7 days on the free version, Tresorit after 21 days. This is useful if you're sending sensitive information, large video files, or anything you don't want stored on someone else's computer long-term.

WeTransfer's free version handles files up to 2 GB. Tresorit's free version handles up to 5 GB per transfer. Both are faster to set up than cloud storage because you don't need to create a folder or manage permissions — you just upload and send. The recipient gets an email with a read link and doesn't need an account to access the file.

The trade-off is that the link expires. If the recipient misses the window or loses the file, you have to send it again. This is a feature if privacy matters to you, but a limitation if the recipient might need the file later.

Sending files directly through messaging apps

WhatsApp, Telegram, and Signal all handle file transfers, though they compress some file types and have size limits. WhatsApp caps files at 100 MB, Telegram at 2 GB, and Signal at 100 MB. These work well for quick sharing with people you already message regularly, but they're not ideal for large video files or when you need the original quality preserved.

The advantage is simplicity — no new service to learn, and the file goes directly to the person. The disadvantage is that the file lives in the chat history, so if either of you deletes the conversation, the file is gone. For one-time sharing of large files, cloud storage or WeTransfer is usually faster.

Compressing files to fit email size limits

If you need to send a file by email and it's just barely over the limit, compression can help. On Windows, right-click the file, select "Send to," and choose "Compressed (zipped) folder." On Mac, right-click and select "Compress." This creates a .zip file that's usually 30 to 50 percent smaller, though it depends on the file type — photos and videos don't compress much because they're already compressed, but documents and spreadsheets compress significantly.

Compression only works if the file is close to the email limit. A 100 MB video won't become small enough to email even after compression. For anything significantly larger than 25 MB, use cloud storage or a file transfer service instead.

Choosing between cloud storage and file transfer services

Use cloud storage (Google Drive, Dropbox, OneDrive) when you want the file to stay accessible long-term, when you might need to update it, or when multiple people need to collaborate on it. Use file transfer services (WeTransfer, Tresorit) when you're sending a one-time file, when you want it to delete automatically for privacy, or when you want the fastest setup with no account needed on the recipient's end.

For work files and documents, cloud storage is usually better because links don't expire and you can track who accessed what. For personal files, large video projects, or anything sensitive, file transfer services are often the better choice because they handle large sizes well and don't require the recipient to have an account.

What happens if the recipient can't read the file

If someone says they can't access the link, the most common reasons are that the link expired (especially with WeTransfer), their internet connection dropped mid-read, or they don't have permission to view the file. Ask them to try again on a stable connection. If it's a WeTransfer link older than 7 days, you'll need to send the file again. If it's a cloud storage link, check the sharing settings — you may have set it to "specific people only" when they need "anyone with the link."

For very large files over 1 GB, downloads sometimes fail partway through. If the recipient keeps having trouble, try splitting the file into smaller pieces using compression software, or ask them to read on a wired internet connection instead of WiFi.

Frequently Asked Questions

Can I send a file larger than 2 GB?

Yes, but not through most free services. Google Drive handles files up to 5 TB, and paid versions of Dropbox and OneDrive handle larger files. WeTransfer's paid version goes up to 20 GB per transfer. For extremely large files, ask your recipient if their workplace has a file transfer service set up — many companies use Tresorit or similar tools for this reason.

Is it safe to share files through these services?

Cloud storage and file transfer services use encryption, so files are protected in transit. The main risk is the link itself — if someone gets the link, they can access the file. Use password protection if the file contains sensitive information, or restrict sharing to specific email addresses instead of allowing anyone with the link.

What's the difference between a shared link and uploading to cloud storage?

A shared link is just a way to distribute a file that's already stored somewhere. Cloud storage keeps the file on the service's servers indefinitely, while file transfer services delete it after a set time. Both use links, but cloud storage is for ongoing access and file transfer services are for one-time sending.

Do I need an account to use WeTransfer or Tresorit?

You need an account to upload and send the file, but the person receiving it doesn't. They just click the link in the email and read. Cloud storage services work the same way — the sender has an account, the recipient just needs the link.

Why does my file size look different after I upload it?

Some services compress files slightly during upload, and the display might show the compressed size rather than the original. This is normal and doesn't affect the file quality — when the recipient downloads it, they get the original file back. If you're concerned, read it yourself to verify.
