+## 🗜️ Request Compression
+
+The SDK supports automatic HTTP request compression to reduce bandwidth usage and improve performance when sending large document payloads. This is especially beneficial for document upload operations.
+
+### Supported Algorithms
+
+- **Gzip** (recommended) - Widely supported, good compression ratio, works with .NET Standard 2.0+
+- **Deflate** - Alternative to Gzip (requires .NET 6.0+ for ZLibStream support)
+- **Brotli** - Best compression ratio (requires .NET Standard 2.1+ / .NET Core 2.1+)
+
+> **Note:** This SDK targets .NET Standard 2.0, so only **Gzip** is available by default. If your project targets .NET 6.0+ or .NET Standard 2.1+, Deflate and Brotli will also be available.
+
+### Basic Usage
+
+Enable compression by passing `CompressionOptions` when creating the client:
+
+```c#
+using Meilisearch;
+
+// Enable Gzip compression with default settings (1400 byte threshold)
+var client = new MeilisearchClient(
+ "http://localhost:7700",
+ "masterKey",
+ CompressionOptions.Gzip());
+
+// All document operations automatically use compression
+var index = client.Index("movies");
+await index.AddDocumentsAsync(largeDocumentCollection);
+```
+
+### Custom Configuration
+
+You can customize compression behavior:
+
+```c#
+var compressionOptions = new CompressionOptions
+{
+ Algorithm = CompressionAlgorithm.Gzip,
+ MinimumSizeBytes = 1024, // Only compress payloads >= 1KB
+ EnableResponseDecompression = true // Request compressed responses from server
+};
+
+var client = new MeilisearchClient(
+ "http://localhost:7700",
+ "masterKey",
+ compressionOptions);
+```
+
+> **Note:** The `EnableResponseDecompression` option only works when using the default `MeilisearchClient` constructor. If you provide a custom `HttpClient`, you must configure `HttpClientHandler.AutomaticDecompression` yourself.
+
+### When to Use Compression
+
+Compression is beneficial when:
+- Sending large document collections (hundreds to thousands of documents)
+- Working with documents containing large text fields
+- Operating on limited bandwidth connections
+- Performing batch operations with significant payload sizes
+
+The default threshold of 1400 bytes ensures compression only applies when beneficial, avoiding unnecessary overhead for small payloads.
+
+### Performance Notes
+
+- Compression adds minimal CPU overhead (typically <5ms for MB-sized payloads)
+- Network transfer time reduction often exceeds compression overhead
+- Most effective with text-heavy documents (JSON, CSV, NDJSON)
+- The 1400-byte default threshold aligns with TCP packet sizes for optimal performance
