**Quick answer:** A file transfer service lets you upload large files and send them to others through a download link or email, without needing shared storage.

## File transfer service explained

A file transfer service is a website or app built for sending large files to other people. Unlike cloud drives, which are built for keeping files, transfer services are built for sending them. You upload, get a link, and the files are removed after a set time.

Things to compare: the size limit per transfer, how long links last, whether the recipient needs an account, whether files are compressed, password options, and what the service says about encryption.

Share Large Files Free sends up to 20 GB per transfer, with no account for either side, files delivered byte for byte, HTTPS in transit and an optional password.

## Ways to send a big file compared

| Method | Typical size limit | Changes the file? | Best for |
| --- | --- | --- | --- |
| Email attachment | Around 20 to 25 MB | No | Small documents |
| Chat apps | Varies by app | Often compresses photos and video | Quick, casual sharing |
| Cloud drive | Your storage space | No | Files you want to keep and edit together |
| File transfer service | Per transfer (20 GB here) | No | Sending large files once, to anyone |

## How a transfer works here

1. Drop your files or a folder on the upload box, on a computer or phone.
2. Optionally open _More options_ to add a password, download limits, an NDA or view-only mode.
3. Upload. Files go up in pieces, so if the connection drops the upload pauses and continues instead of starting again.
4. Share the link, show the QR code, or have it emailed to the recipients.
5. The recipient opens the link in any browser and downloads the original files.
6. When the link expires, the files are deleted.

## A quick checklist for choosing a service

- Is the per-transfer limit bigger than your largest job?
- Does the recipient need to sign up? Many people give up if they do.
- Are files delivered unchanged, or re-compressed?
- Can you add a password and control how long the link lasts?
- Can a failed upload resume, so a slow connection is not a problem?

## Frequently asked questions

### How is a transfer service different from Google Drive?

Drive stores files long term in your account. A transfer service delivers files temporarily through a link, often with no account needed.

### Does the recipient need an account?

Not here. They only need the link and a browser.

### Are my files compressed when I send them?

No. Files are delivered byte for byte, exactly as you uploaded them.

### What if my files are bigger than the limit?

Split them across several transfers, for example by folder, or cut one huge file into parts with the split file tool. The limit here is 20 GB per transfer.
