Simple Process
How It Works
Three steps between your support request and a private file link.
1
Select Your File
Drag and drop your file onto the upload area, or click to open a file browser. Supports documents, images, archives, logs, and most common file types.
2
Upload Securely
Your file is uploaded via an encrypted connection and stored securely. Dangerous file types are blocked automatically to protect all users.
3
Share Your Link
Copy the private link into your UnderHost support ticket so our team can review the file without email attachment limits.
Common Uses
What Can You Share?
UnderHost File Upload is built for practical hosting and support workflows.
Support Screenshots
Share screenshots of server errors, control panel issues, or website problems directly with the UnderHost support team.
Server Logs
Upload error logs, access logs, cPanel error files, or PHP logs for your support ticket without worrying about email size limits.
Backups & Archives
Send compressed website backups, database dumps, or configuration archives to your team or hosting support when migrating or troubleshooting.
Documents & Reports
Share invoices, contracts, specification documents, or technical reports with clients or team members without using email attachments.
Security First

Every upload goes through validation and security checks before storage. Files are served through a controlled download endpoint - not exposed directly.
Dangerous file types blocked by extension and MIME check
Random unguessable share links (64-bit entropy)
Script execution disabled in storage directory
No directory listing - storage is not browsable
Upload rate limiting per IP address
CSRF protection on every upload request
Files automatically expire after 30 days
Files served via controlled PHP download handler

About This Tool
UnderHost File Upload
UnderHost File Upload is a secure, lightweight file sharing tool designed for UnderHost customers, support staff, and agency partners. It is part of the UnderHost ecosystem alongside the main hosting platform, client area, documentation site, and network status page.
This tool is focused on practical hosting and support workflows: sharing screenshots for support tickets, sending server logs to the technical team, transferring backup archives during migrations, or sharing configuration files with clients.
Files are stored on UnderHost infrastructure and accessible only via the private share link generated at upload. Links are not indexed, not discoverable, and not publicly listed anywhere. Anyone with the link can download the file, so avoid sharing links through untrusted channels when the file contains sensitive information.
Important: Only download files from people you trust. UnderHost does not review the content of uploaded files. If you receive a share link you did not expect, contact the sender to verify it before downloading.
