Secure file transfer for accountants and accounting firms
Send sensitive client files without the email risk.
secureeu.eu lets accountants share tax returns, payroll exports and bookkeeping files through encrypted links. Files are encrypted in the browser before they leave your computer, and your clients don't need an account to download them.
The Problem
Why accountants need a better way to share files
Accountants handle some of the most sensitive financial data their clients have, but most of it still moves through email. Inboxes get hacked, attachments get forwarded by mistake, and large files like scanned receipts or full-year exports are often blocked by mail servers.
Email attachment limits (typically 20–25 MB) for ledgers and scanned documents
Clients sending tax documents through unsecured channels
Having to chase signed engagement letters and ID copies
Storing client files in shared folders that anyone in the firm can browse
Pressure during tax season to move files quickly without losing control of them
Common Documents
Files accountants send and receive
Annual accounts and trial balances
VAT returns and supporting workpapers
Payroll exports (gross-to-net, P11/Lohnabrechnung)
Bank statements and reconciliation files
Scanned invoices and receipts
Client tax returns and tax-authority submissions
Engagement letters and KYC/AML documents
Year-end audit packs and management accounts
How It Works
Three steps. Totally private.
Create a secure link
Drop the file into your browser. It's encrypted with AES-256 on your device before it ever leaves.
Send or receive files
Share the link by email, chat or your portal. The recipient clicks and downloads — no signup, no app.
Files are protected and expire
Choose an expiry of 1–30 days, optionally add a password and download limit. After expiry the file is permanently deleted.

Trust & Security
We can't read your files. By design.
Browser-side encryption
Files are encrypted with AES-256-GCM in your browser via the WebCrypto API, before they leave your device.
Privacy-first design
The decryption key sits in the URL fragment, which browsers never send to servers. We technically cannot read your files.
No unnecessary accounts
Senders and recipients don't need to create profiles. Adoption across teams and external parties is friction-free.
Expiring links
Choose a retention window of 1–30 days, or revoke any link at any time. Files are permanently deleted on expiry.
EU-hosted, GDPR-conscious
Files are stored on Hetzner infrastructure in Germany / Finland. The platform is designed with GDPR in mind: minimal data collection, short retention, and no transfer of stored files to non-EU regions.
