WebDAV vs FTP in 2026: Which Protocol Should You Actually Use

Description and use

In 2026, WebDAV outperforms FTP for small files, offers local‑drive integration, stronger authentication, and easier firewall configuration, making it the preferred protocol for most modern use cases.

Problem

Choosing a file transfer protocol that balances performance, security, and usability for modern workflows.

Outcome

WebDAV outperforms FTP for small files, matches FTP for large files, offers native local‑drive integration, stronger authentication, and easier firewall handling, making it the preferred protocol for most modern use cases.

Workflow

• Set up vsftpd with TLS on port 21 and passive range.
• Set up Apache with mod_dav over HTTPS on port 443.
• Benchmark upload/download of 1 GB single file, 1,000 small files, and random 4 KB reads.
• Compare throughput, IOPS, and authentication models.
• Evaluate firewall/NAT behavior and client tooling.
• Decide on protocol based on use case.
• If WebDAV, install client (ScsDriver on Windows, built‑in clients on macOS/Linux/iOS/Android).
• If FTP, use for one‑off large transfers or legacy equipment.

Evidence

Upload 1 GB single file: FTP (TLS) 78 MB/s, WebDAV (HTTPS) 76 MB/s

Upload 1,000 small files: FTP 4 MB/s, WebDAV 22 MB/s

WebDAV is a file system protocol. It gives a remote server a file system interface.

FTP is a disaster for modern networks. It needs port 21 for control and a separate random port for data.

If you have not set up either yet, here is the path I recommend: Pick a WebDAV‑capable server. Nextcloud self‑host is the most popular; Synology, QNAP, and most NAS devices have it built in.
