Filarr Send
Send, request, deposit. Encrypted before it leaves your device.
One link to send a file, one link to receive some. Encryption happens in your browser — the key never reaches our servers, and nobody needs an account.
- No account
- End-to-end AES-256-GCM
- Up to 4 GB free
- Source available

AES-256-GCM encryption in your browser. Temporary storage (max 7 days, auto-deleted).
Up to 4 GB in total, no account. Higher plans raise these limits →
Receive files, encrypted for you alone.
Create a deposit link. Your contacts drop their files in it, encrypted in their browser with your public key: only you can open them. No account needed — not for you, not for them.
- 1
Your browser generates a key pair. The public key travels in the link, the private key stays with you.
- 2
Each depositor encrypts for your public key — up to 10 files per deposit, 2 GB in total for the request.
- 3
You decrypt the deposits from your manage link, or from your dashboard when signed in.
Collection templates
One click pre-fills the list of documents to provide — editable afterwards.
With an account
Deposits found on all your devices, automatic reminders, email notifications, closing the collection with a ZIP of everything received, and deposits restricted to a verified address.
Received a deposit link?
Paste it here to open it. Your files will be encrypted in your browser with the key of the person asking for them — Filarr cannot read them.
- Up to 10 files per deposit, 2 GB in total for the request.
- No account: the link is enough, an invisible anti-spam check protects the requester.
- This browser keeps a local trace of what you deposited (name and date only).
Signed in?
Requests addressed to your verified email show up in your dashboard — even if you lose the link.
Everything Filarr Send can do
Every option below exists today, in your browser, with nothing to install.
Encrypted before it leaves
AES-256-GCM in your browser. The key lives after the # of the URL and never reaches our servers.
Expiry and quota
From 1 hour to 7 days without an account (30 days with a plan), from 1 to 10 downloads.
Burn after reading
Set the quota to 1: the encrypted file is deleted as soon as it is downloaded once.
Argon2id password
Brute-force-resistant derivation, in the recipient’s browser. The password never travels.
Preview only
The recipient views the file on screen, with no download button. A request, not a lock.
Revocation without an account
A manage token kept in this browser is enough: the encrypted file is wiped from our servers.
QR code, email, native share
Hand the link to a phone, send it from your mail client or the system share sheet.
Direct, parallel upload
16 MB chunks encrypted and uploaded in parallel straight to storage, with live speed and ETA, per-chunk retry.
Same links, ceilings that follow your plan

How does secure file transfer work?
Proven cryptography, run in your browser before anything leaves.
- 01
Encrypted locally
The file is split into chunks encrypted with AES-256-GCM on your device. The server only receives unreadable bytes.
- 02
Key in the URL
The decryption key lives after the #. Per web standards, that part is never transmitted to the server.
- 03
Unreadable by the host
Without the key we only see a block of bytes. Zero tracking, zero AI scraping, automatic deletion on expiry.
Frequently asked questions
Does my recipient need an account?
No. They open the link, the file decrypts and downloads in their browser. They can even view it without downloading.
What is the maximum file size?
4 GB in total without an account. Signed in, the limit follows your plan: up to 50 GB in total with Pro.
Can I send several files at once?
One link is one file: to send several, compress them into an archive. To receive several, the file request accepts up to 10 files per deposit.
Can you read my files or hand them over?
No, technically impossible. Without the key — known only to you and your recipient — we only see a block of bytes. We can delete a reported file, never read it.
What if I lose the link?
Without an account, the key only exists in the URL: find it in the “My links on this device” list of this browser, otherwise send the file again. Signed in, your dashboard rebuilds the secret link on all your devices.
Why a password if the key is already in the URL?
To protect against an intercepted link. The password, shared through another channel, is derived with Argon2id on the recipient side and combined with the URL key: one without the other is not enough.
Need a complete workspace for your notes and files?
Filarr is a local-first vault: notes, files, knowledge graph and preview of 80+ formats, encrypted on your disk. Send is its front door.
