The Secure Dual-Panel File Transfer Client for macOS

OmniFile is a native Mac app for moving files between your Mac, your servers and your cloud storage. Two panels side by side, tabs for every connection, and transfers that are checked before anything is replaced or removed.

Key Features

🌐 Servers and Cloud Storage

  • FTP - With passive or active mode
  • FTPS - Explicit (AUTH TLS) and implicit, with TLS 1.2 and 1.3 and the TLS session reuse that strict servers such as vsftpd, FileZilla Server and ProFTPD require
  • SFTP - Password or key login (Ed25519, ECDSA and RSA, with or without a passphrase)
  • Amazon S3 and S3-compatible storage: Backblaze B2, Wasabi and DigitalOcean Spaces
  • Google Drive, Dropbox and OneDrive - With guided setup for each service. Google Docs, Sheets and Slides download as Microsoft Office, OpenDocument or PDF files, as you choose

📂 Dual Panels, Tabs and Drag & Drop

  • Side-by-side panels - Your Mac, a server or a cloud service in either panel
  • Tabs - Keep several connections open in one window
  • Drag and drop in every direction - Between panels, onto tabs, and to and from Finder, including whole folders
  • Copy or move - Drags to or from a server copy; hold ⌘ to move, ⌥ to copy
  • Panels that stay current - Local folders update when files change, and server folders refresh when you return to OmniFile
  • Search - Filter a folder or run an advanced search
  • Hidden files - Separate settings for your Mac and for servers, ⇧⌘. to switch

🔄 Compare and Sync

  • Folder comparison - Newer, larger, different and one-side-only files each get their own color, chosen to stay readable for color-blind users and in dark mode
  • Folder sync - One-way or two-way between panels, where two-way sync picks the newer copy
  • Safe by design - Sync stops instead of deleting anything if a folder listing fails, and shows which files failed and why
  • Real file dates - Dates from FTP and SFTP servers are read correctly and kept on download and upload

⚡ Transfers You Can Trust

  • One transfer queue - Uploads, downloads and transfers between servers and cloud services
  • Verified transfers - Downloads finish in a temporary file and replace yours only when complete and checked
  • Safe moves - The original is removed only after the copy has finished and been checked
  • Safe resume - Interrupted transfers resume, but only when OmniFile itself was interrupted, so old and new versions of a file are never mixed
  • Automatic retries - A dropped connection gives an error and the transfer is retried
  • Survives restarts - Transfers left in the queue are offered again the next time you open OmniFile
  • Large files - Big uploads to S3-compatible storage, Google Drive, OneDrive and Dropbox are sent in parts

✏️ Edit Server Files in Any Mac App

Right-click a server file and choose Edit with, or press ⌘E. OmniFile uploads the file after every save and asks before overwriting a change someone else made.

👁️ Previews

  • Quick Look and a built-in preview panel
  • Syntax-highlighted code for Swift, JavaScript, TypeScript, Python, JSON, YAML, HTML, CSS, shell, PHP, SQL, C-family and more
  • Images, PDFs, audio, video, Markdown, CSV and archives, plus image thumbnails
  • Works on cloud storage - Previews on Google Drive, Dropbox and OneDrive too

🔍 Duplicates and Similar Images

  • Duplicate finder - Scan local folders, servers and cloud storage for identical files, and export the results as CSV
  • Similar images - Find visually similar photos with perceptual matching
  • Never deletes every copy - Local duplicates go to the Trash

📋 Site Manager and History

  • Folders - Group your sites by project or client
  • Quick connect - Connect from the toolbar, and save the server to the Site manager with one click
  • Import and export - Back up and move your site list, or import sites from FileZilla
  • Connection history - Recent connections with favorites

🔒 Security

  • Keychain only - Passwords, keys and tokens are stored in the macOS Keychain, never in the site list
  • SFTP server identity - OmniFile remembers each server’s key and asks before connecting if it changes
  • Certificate checks - FTPS certificates are checked against macOS’s trust settings
  • SFTP keys made easy - Generate a new key, or install your public key on a server, straight from the Site manager
  • Trash first - Deleted local files go to the Trash, and OmniFile asks first. Server deletes warn that they can’t be undone

🛠️ File Operations and macOS Integration

  • Copy, move, rename, delete and new folder - On your Mac and on servers
  • Get info and change permissions - Edit permissions on server files
  • Compress and extract - Zip and tar archives, without overwriting files unless you say so
