Compress

Compressing the Response before Sending it to the Client {: .subtitle }

The Compress middleware enables the gzip compression.

Configuration Examples

??? example "File -- enable gzip compression"

```toml
[Middlewares]
  [Middlewares.test-compress.Compress]
```

??? example "Docker -- enable gzip compression"

```yml
a-container:
      image: a-container-image 
        labels:
          - "traefik.middlewares.test-compress.compress=true",
```

Notes

Responses are compressed when:

• The response body is larger than 512 bytes.
• The Accept-Encoding request header contains gzip.
• The response is not already compressed, i.e. the Content-Encoding response header is not already set.
