Secure file sharing, with a link you control
Upload a file and share the link — read-only, with its own password and expiry, revocable whenever you’re done. The secure way to send documents, encrypted at rest the whole time.
From file to protected link
The same sharing controls the app uses, opened right here — nothing to relearn later.
-
01
Drop in a file
PDF, Word, Excel, PowerPoint and image files — it uploads into your documents and is AES-256-GCM encrypted before it ever touches our disk.
-
02
Set the lock
The sharing controls open right here: one chip adds a password, one adds an expiry — and a live link re-arms in place, so the URL you already sent keeps working.
-
03
Send it anywhere
Email, chat, wherever — the protection travels with the link. Share the password on a different channel, and revoke the link whenever you're done.
Encryption at rest is on every plan. Setting a password and expiry on links is part of Personal and Business.
Who shares files this way
Freelancers and consultants
Contracts, proposals and invoices that should not sit in a client's inbox forever.
Accountants and bookkeepers
Tax returns, statements and payroll reports sent to clients behind a password.
HR and hiring
Offer letters, payslips and ID documents that only one person should open.
Property and legal
Leases, title documents and case files shared for a set time, then closed.
What the recipient meets
A read-only page, a password challenge if you set one, and nothing they can change. Forwarded links carry the lock with them — and a revoked link dies for everyone at once.
How to send documents securely through email
Email is fine for the message. The document itself should travel as a link you can lock and take back.
Start with step one ↑-
1
Upload the file here, not to the email
Drop it into the box above. It is encrypted before it is stored, and the email never carries the document itself.
-
2
Lock the link
Add a password and an expiry in the sharing controls. On the free plan the link is read-only and revocable; password and expiry come with Personal.
-
3
Paste the link into your email
Write the email as usual and paste the link where the attachment would have gone. It works in Gmail, Outlook or any other mail app.
-
4
Send the password another way
Text it, say it on a call, or send it in a chat. A password in the same email as the link protects nothing if that email is forwarded.
-
5
Revoke it when you are done
Once they have what they need, revoke the link. Anyone who opens it afterwards, including a forwarded copy, gets nothing.
Why a secure link beats an email attachment
An attachment is a copy that leaves your hands for good. A link stays yours to lock, time out or revoke.
| Feature | Email attachment | Secure link |
|---|---|---|
| Can be taken back after sending | No | Yes |
| Stops working on a date you pick | No | Yes |
| Needs a password to open | No | Yes |
| A forward carries the same lock | No | Yes |
| Stored encrypted | No | Yes |
| Recipient needs no account | Yes | Yes |
Password and expiry need Personal or Business. Revoking and encryption are on every plan.
Six habits for secure file sharing
None of these need special software. They are what keeps a shared file from outliving its purpose.
-
Share links, not attachments
An attachment is a copy you can never recall. A link points to one copy you stay in control of.
-
Give every link an end date
Most files are needed for days, not forever. An expiry closes the link even if you forget to.
-
Keep the password off the email
Send the link and the password through different channels, so one leaked message is not enough.
-
Use one link per person
A separate link for each recipient means you can cut off one person without breaking everyone else's access.
-
Revoke when the job is finished
Closing access you no longer need is the simplest way to keep old documents from resurfacing.
-
Share only what they need
Send the signed page or the one report, not the whole folder. Less shared means less to lose.
How the link behaves
What a recipient sees, what the password actually protects, and what revoking does.
[email protected]What's the most secure way to send documents?
A link you control beats an attachment. An emailed file is gone the moment you press send — it can't be revoked, expired, or password-gated after the fact, and every forward makes another copy. A read-only link keeps the document in one place, behind whatever protection you set, and dies when you say so.
What does the recipient see?
A read-only copy of the document in their browser — no account, nothing they can change. If the link carries a password, they enter it first.
Is this the same as password-protecting the PDF?
No, and the difference matters: the password and expiry live on the LINK, not inside the file. The document sits encrypted with us and is served read-only; a PDF someone downloads is an ordinary PDF. If you need the file itself encrypted for offline handling, that's a different tool.
Can I revoke a link after sending it?
Yes — from the sharing controls, immediately. A revoked link stops working for everyone who has it, including anyone it was forwarded to.
Why does it need an account?
Because a secure link has to belong somewhere: the account is where you see the link, change its password, move its expiry, or revoke it. The free plan is enough — no card.
Is secure document sharing free here?
Sharing itself is free — upload a file and share the read-only link on any plan, no card. Setting a password and expiry on the link is part of Personal and Business, and protections already on a link keep enforcing even if a plan lapses: a downgrade never silently unlocks a shared document.
What files can I share, and how big?
PDF, Word, Excel, PowerPoint and image files. Office files are converted to PDF so the recipient can read them in any browser. Files can be up to 10 MB on Free, 25 MB on Personal and 50 MB on Business.
How do I send documents securely through email?
Don't attach them. Upload the file, add a password and an expiry to its link, paste the link into the email, and send the password by text or on a call. The full steps are on this page.
What happens if someone guesses the password?
They get five tries. After that the link refuses every attempt for 15 minutes, so a password cannot be guessed by trying thousands of times.
Can I share with more than one person?
Yes. Use one open link for anyone you give it to, or create a separate link for each email address so you can revoke one person without affecting the rest.
