The simplest way depends on file size and who needs it

A big file is usually anything over 25 megabytes — too large for most email systems to handle without bouncing back or taking hours to send. The method you choose depends on three things: how big the file is, whether the person receiving it has a specific service already, and whether they need the file once or repeatedly.

Email remains the easiest choice for files under 25 MB, but anything larger needs a different route. The most common options are cloud storage services (Google Drive, Dropbox, OneDrive), file transfer sites (WeTransfer, Tresorit), or a shared folder if you and the recipient work together regularly. Each has a different setup time and works better in different situations.

Key Takeaways

  • Files over 25 megabytes usually bounce back from email, so you need a different method depending on file size and how often the recipient needs access.
  • Google Drive, Dropbox, and OneDrive let you share files once or give ongoing access, and work on phones and computers without extra software.
  • WeTransfer and similar sites are fastest for one-time sharing because they require no account from either person, though the link expires after a few days.
  • Shared folders work best when multiple people need to edit the same files regularly, but require everyone to have the same service.
  • Always check file size before you start — your device's storage space and internet speed affect how long upload takes.

Sending through email with compression

If your file is just slightly over the email limit, compressing it often brings it under the threshold. On Windows, right-click the file, select "Send to," then "Compressed (zipped) folder." On Mac, right-click and choose "Compress." This creates a smaller version without losing the original — the recipient unzips it on their end by double-clicking.

Compression works best for documents, photos, and videos that are only a few megabytes over the limit. It does not work well for files already compressed (like MP4 videos or JPG photos), because they are already squeezed as small as they go. If compression does not get you under 25 MB, switch to one of the methods below.

Using Google Drive for one-time or ongoing sharing

Google Drive is free and requires only a Google account (Gmail counts). Upload your file by going to drive.google.com, clicking the "New" button on the left, selecting "File upload," and choosing your file. Once it uploads, right-click the file and select "Share." You can then paste a link in an email or message, or type in the recipient's email address directly.

When you share a link, you choose whether the recipient can view only, comment, or edit. "Viewer" means they can see it but not change it — best for finished work. "Editor" lets them make changes, which is useful if you are working on something together. The recipient does not need a Google account to view or read the file, though they do need one to edit.

Google Drive keeps the file in one place, so if you update it later, the recipient sees the new version without you sending anything else. This makes it better than email for ongoing projects. Files stay accessible as long as you keep your Google account active.

Using WeTransfer for quick one-time sharing

WeTransfer (wetransfer.com) is the fastest option if you want to send something once and do not want to set up a shared folder. Go to the site, click "Add Files," select your file, type the recipient's email address, and click send. They receive an email with a read link within minutes.

The link works for 7 days, then expires — the recipient must read the file during that window or ask you to send it again. WeTransfer is free for files up to 2 GB. Neither you nor the recipient needs an account, which makes it simpler than Google Drive for one-time sharing. The trade-off is that you cannot update the file or give ongoing access the way you can with a shared folder.

Setting up a shared folder for team files

If multiple people need to access and edit the same files regularly, a shared folder in Dropbox, OneDrive, or Google Drive works better than sending files back and forth. In Google Drive, create a new folder by clicking "New," then "Folder." Right-click the folder and select "Share," then add the email addresses of everyone who needs access.

Everyone with access can upload files, read them, and edit documents inside the folder. Changes appear for everyone when ready — if one person edits a document, the others see the updated version without waiting for an email. This eliminates the confusion of multiple versions floating around in inboxes.

Shared folders require everyone to have the same service (all Google Drive, all Dropbox, or all OneDrive). If your team uses different services, pick one and ask everyone to create a free account. Most people already have at least one of these.

Checking file size before you upload

Before you start, find out how big your file actually is. On Windows, right-click the file and select "Properties" — the size appears in the window that opens, usually listed as "Size" in megabytes or gigabytes. On Mac, right-click and select "Get Info" — look for "Size" near the top.

Your internet speed affects upload time more than the method you choose. A 500 MB file on a slow connection can take 10 minutes or longer. If you are on mobile data or a weak WiFi signal, consider waiting until you have a stronger connection. Most services show upload progress and let you pause and resume, so you can start the upload and come back to it.

When file sharing goes wrong

If a link stops working, the most common reason is that the sender deleted the file or changed the sharing settings. Ask the sender to check that the file still exists and that your email address still has access. If you are the sender and someone says the link is broken, go back to the file, right-click "Share," and make sure the recipient's email is still listed with the correct permission level.

If a file is too large to upload at all, your internet connection may have dropped or the service may have a size limit. WeTransfer caps files at 2 GB, but Google Drive and Dropbox allow much larger uploads. Try uploading again, or switch to a different service if the problem continues. If the upload keeps failing partway through, your connection is probably dropping — move closer to your router or switch to a wired connection if possible.

Frequently Asked Questions

What is the difference between sharing a link and sharing with an email address?

Sharing a link means anyone with the link can access the file, even if you do not know their email. Sharing with an email address means only that specific person can open it. Use a link for public sharing or when you do not have the recipient's email. Use an email address when you want to control exactly who sees it.

Can I share a file if I do not have a Google account or Dropbox?

Yes — WeTransfer and similar services do not require an account from either person. You upload the file on their site, type the recipient's email, and they get a read link. This is the fastest option if you do not want to create an account, but the link expires after a week.

What happens if I delete a file after I share it?

If you delete a file from Google Drive or Dropbox, anyone with a link to it loses access when ready. If you shared a folder instead of a single file, deleting one file inside the folder removes it for everyone. Always make sure you want to delete something before you do, especially if others are using it.

Is it safe to share files this way?

Google Drive, Dropbox, and WeTransfer all encrypt files while they travel over the internet, so they are as safe as email. The main risk is sharing with the wrong person — double-check the email address before you hit send. If you are sharing sensitive information, consider using a service that lets you set a password or expiration date on the link.

Why does my file keep failing to upload?

The most common reason is a weak or dropping internet connection. Try uploading again, or move closer to your WiFi router. If it keeps failing, check that your file is not corrupted by trying to open it on your own device first. If the file opens fine but still will not upload, try a different service or contact that service's support.
