Sending big files: where should it go?

This is a ranking. But the criteria come first: a ranking whose criteria you cannot see says nothing at all.

Up front: this was written by the people who made EZPZ Drop, which is on the list below. So we did not give ourselves the overall top spot, we state the criteria before the ranking, and we spell out where we lose. Every number comes from the service’s own published documentation, with the date we checked it.

What changed in 2026

WeTransfer used to be the reference point for free transfers. Per its own help centre, the free plan is now up to 10 transfers or 3 GB in any 30-day period, and it requires an account. It is no longer "2 GB per transfer, no sign-up".

Most articles you will find still describe the old terms, including the ones about what to do when you hit the free 2 GB limit. Counting again against today’s terms is where this piece starts.

What we measure

Five criteria. Each one is something you can check yourself.

Speed is not a criterion here. It depends on your network, so the number we measure is not the number you would get.

The ranking: no account, and the server cannot read it

That is the axis. A different axis gives a different order: rank by size alone and this list flips. Read it together with the table below.

1. EZPZ Drop

• What it is: the file is encrypted in your browser before it is uploaded. The key lives after the # in the link, and by specification that part is never sent to the server. On the same network it skips the server entirely and goes device to device. No account.
• Choose it when: the other person does not have to be online right now, and you would rather the contents did not sit readable on someone else’s server.
• Not for: 4 GB per send. Links last 24 hours at most, so the next day it is gone. It will not email the file for you and the recipient gets no notification.

2. Send Anywhere, the 6-digit key

• What it is: the other person types a 6-digit number and the transfer goes device to device. Its own help centre states that files sent this way are not stored on the server. No account needed.
• Choose it when: both of you are online right now. Up to 50 GB, the largest on this list. On size alone it beats us comfortably.
• Not for: the key is single-use and expires in 10 minutes. Switch to link sharing and the file does go through the server: 10 GB and 48 hours on the free tier, with a 10 GB monthly download cap on free accounts.

3. LocalSend

• What it is: an open-source app that works inside your own Wi-Fi. "No account, no login, no servers," as it puts it.
• Choose it when: moving files between your own phone and laptop at home or in the office. It works with the internet down.
• Not for: anything outside that network. Both devices need the app installed.

4. PairDrop

• What it is: open source, runs in the browser. A 6-digit pairing code or a room code connects devices across different networks.
• Choose it when: you want device-to-device without installing anything.
• Not for: it is easy to file next to LocalSend because of the name, but the design differs. It uses a signalling server to set up connections, and when a direct link cannot be made behind a router, its own TURN server relays the traffic. "No servers at all" is not accurate here.

5. Dropbox Transfer

• What it is: create a link from your Dropbox account. Free is 2 GB per transfer, expiring after 7 days.
• Choose it when: you already use Dropbox and want the file to sit there for a few days.
• Not for: an account is required and the file is uploaded unencrypted from the service’s point of view. Free storage is 2 GB, so it competes with your own space.

6. WeTransfer

• What it is: the best-known name here. Links, email delivery, recipient notifications.
• Choose it when: the recipient already knows the service and email delivery is simpler for them.
• Not for: free is 10 transfers or 3 GB per 30 days, with an account. A handful of sends a month and you are done.

7. Cloud share links: Google Drive, Naver MYBOX

• What it is: upload once, share the link. Google Drive gives 15 GB free (shared with Gmail and Photos); Naver MYBOX gives 30 GB.
• Choose it when: the file should stay available indefinitely for several people.
• Not for: it keeps eating your own storage, it stays until you delete it, and the server can read it.

The whole thing in one table

Checked against each service’s own documentation on 22 September 2026. Plans change without notice. Before anything important, check the figure on the service’s own site.

Why email and chat run out first

This is where most people get stuck before they search. Gmail attachments cap at 25 MB; Naver Mail’s ordinary attachments cap at 10 MB, after which it switches to large attachments: up to 2 GB per file, available for 30 days and 100 downloads.

KakaoTalk allows 300 MB per file. People often ask how long files stay there; Kakao does not publish that number. Its official answer is that the storage period changes with system load, so it cannot be stated precisely. The "a few days" figures you see elsewhere have nothing behind them.

What a dead service teaches

The cleanest free transfer ever built was Mozilla’s Firefox Send: no account, end-to-end encrypted, one link. It closed in September 2020.

The reason was not technical. According to Mozilla, some users had begun using it to ship malware and run spear-phishing campaigns. A report button and required sign-in were planned; the service was shut down instead.

That is where accounts and caps come from. A channel that lets anyone push large files anonymously will be abused. Worth knowing before cursing the limits.

About the one we made

EZPZ Drop locks the file in your browser before uploading it. The key goes after the # in the link, and that fragment is never sent to the server by design, so what sits on the server is a blob nobody can open. On the same network it skips that step and sends device to device.

What it cannot do is just as clear. 4 GB per send, 24 hours maximum. No email delivery, no notification to the recipient, no team features. And nobody has heard of it, so the person receiving the link may hesitate.

If you need size and long retention, another service on this list is better. When you want to send without an account and without the contents sitting readable on a server, that is where this one fits.
