# Decompress CloudWatch Logs
<a name="writing-with-cloudwatch-logs-decompression"></a>

If you are using Firehose to deliver CloudWatch Logs and want to deliver decompressed data to your Firehose stream destination, use Firehose [Data Format Conversion](https://docs.aws.amazon.com/firehose/latest/dev/data-transformation.html) (Parquet, ORC) or [Dynamic partitioning](https://docs.aws.amazon.com/firehose/latest/dev/dynamic-partitioning.html). You must enable decompression for your Firehose stream.

You can enable decompression using the AWS Management Console, AWS Command Line Interface or AWS SDKs.

**Note**  
If you enable the decompression feature on a stream, use that stream exclusively for CloudWatch Logs subscriptions filters, and not for Vended Logs. If you enable the decompression feature on a stream that is used to ingest both CloudWatch Logs and Vended Logs, the Vended Logs ingestion to Firehose fails. This decompression feature is only for CloudWatch Logs.
