How to send large files: every free way, compared
Short answer
Email stops at 20–25 MB, so for anything bigger, send a link instead of an attachment. The quickest free way: upload the file below (no account, up to 3 GB per file) and paste the link into your email or chat. For files you'd rather nobody else could read, use Encrypted Share; for files of any size, send peer to peer.
No files selected.
More than one file selected — they'll each still get their own link, plus one combined link to download all of them at once as a .zip.
Every free way to send a large file
There are really only four approaches: attach it, share it from cloud storage, use a transfer site, or send it straight from your device. Here's what each one allows on its free plan.
| Method | Free limit | Recipient needs | Best for |
|---|---|---|---|
| Email attachment | 25 MB in Gmail and Outlook.com (about 18 MB of real file) | Nothing | Small documents |
| Google Drive link | 15 GB of storage, shared with Gmail and Photos | Sometimes a Google sign-in, depending on sharing settings | People already on Google |
| OneDrive link | 5 GB of storage | Sometimes a Microsoft sign-in | Outlook and Office users |
| iCloud Mail Drop | 5 GB per email, link lasts 30 days | Nothing | Sending from Apple Mail |
| WeTransfer Free | 3 GB or 10 transfers in any rolling 30 days | Nothing | Occasional sends |
| Send Shed Quick Share | 3 GB per file, no monthly cap, no account | Nothing | Anything up to 3 GB, fast |
| Send Shed Encrypted Share | 5 GB per file with a free account | Nothing | Private files: contracts, IDs, tax papers |
| Peer to peer (Send Shed P2P) | No size limit; nothing is stored | To keep the page open while it sends | Very large files, 10 GB and up |

Why email can't send large files
Attachments are encoded before they're sent, which makes them about a third bigger. So Gmail's and Outlook.com's 25 MB limits really fit a file of about 18 MB. Work email set up on Microsoft 365 usually allows a little more, but the person you're sending to has their own limit too, and the smaller one wins. Over the limit, Gmail and Outlook quietly switch to a Drive or OneDrive link anyway. Sending a link yourself just skips the bounce.
The best way to send large files, by situation
- One file, sent once, no fuss: a transfer link. Upload it above, copy the link, paste it anywhere. The recipient doesn't need an account or an app.
- A big video: a link keeps full quality, where WhatsApp, iMessage and email compress or refuse it. See how to send a large video file for free, or from an iPhone.
- Something private: use an encrypted link, so the file is locked in your browser before it uploads. More on sending large files securely.
- Huge files (tens of GB): send peer to peer. The file goes straight from your browser to theirs, so there's no upload limit, but you both need to be online.
- Files you'll keep updating: cloud storage such as Google Drive or OneDrive, so the link always points to the latest copy.
How to send large files by email
You can't make email carry a bigger file, but you can put a link in the email instead:
- Upload the file above (or to Drive, OneDrive or Mail Drop).
- Copy the link.
- Paste it into your email, with a line saying what it is and how long the link lasts.

How to send a large PDF
Scanned PDFs are often big because each page is a full-size photo. Try shrinking it first: on a Mac, open it in Preview and choose File > Export with the Reduce File Size filter; in Adobe Acrobat, use Reduce File Size. If it's still over 18 MB or so, send it as a link instead. Contracts, tax returns and ID scans are worth sending encrypted rather than as a plain attachment.
Should you zip files first?
Zipping is good for bundling lots of files into one, but it barely shrinks photos, videos or PDFs, which are already compressed. You don't need to zip before uploading here: pick several files at once and you get one link that downloads them all as a .zip.
Quick answers
What is the largest file I can email?
About 18 MB of real file in Gmail or Outlook.com (both have a 25 MB limit), because attachments grow by about a third when they're sent.
What is the best free way to send large files?
Send a link instead of an attachment. A transfer link with no account is quickest for one-off files; peer to peer has no size limit at all.
How do I send a file larger than 25 MB?
Upload it to a file-sharing service, copy the link and paste the link into your email or message.
Is it safe to send large files with a link?
A plain link can be opened by anyone who has it. For private files, use an encrypted link, a password, a download limit or a short expiry.
