Convert CSV and JSON to optimized Parquet files directly on your own AWS. Fast.
Purpose-built and lightweight.
How Parqify Works
Parqify provides a server application, packaged as an AMI, that customers can deploy within their AWS environment.
This server reads CSV and JSON files from a specified S3 bucket, converts them to the Parquet format, and then writes the converted files back to another S3 bucket.
Features
Fast conversion
Parallel processing optimized for large Amazon S3 datasets.
Process multiple files concurrently for improved performance.
Runs in Your AWS Account
All processing happens inside your AWS account.
No data leaves your infrastructure.
Friendly Web UI
Create, edit, import/export conversion configs. Configure S3 bucket names, file prefixes, and other conversion parameters through a simple web interface.
Scalability
Scale the EC2 instance size based on your dataset size and performance requirements.
Easy Deployment
Deploy Parqify via AWS Marketplace.

Data Lake Optimization
Convert raw CSV and JSON data in Amazon S3 to Parquet for more efficient storage and faster querying with Amazon Athena or Amazon Redshift Spectrum.
Data Sharing
Share Parquet files instead of CSV or JSON for more efficient data exchange and better performance when consumed by AWS analytics services and downstream data pipelines.
🚀 Optimized for Conversion — Not General ETL
Parqify uses a lightweight streaming pipeline designed specifically for S3 → Parquet.
Unlike Spark-based tools, it avoids cluster startup, staging datasets, and JVM overhead. Files are streamed directly from S3 into Parquet writers with column-aware buffering and parallel IO.
The result:
- 🚀 Faster startup
- 🚀 Lower memory usage
- 🚀 Fewer S3 operations
- 🚀 Smaller Parquet output
- 🚀 Better performance for Amazon Athena and Amazon Redshift
Perfect for teams that just need Parquet — without building ETL infrastructure.
