Frequently Asked Questions

Yes, completely free with no limits. Convert any size SQLite database to Parquet format without registration or payment.

Yes. Files are encrypted during transfer and automatically deleted from our servers immediately after conversion. We never store or access your data.

Yes. The converter maintains all table structures, column names, and data types. SQLite types are mapped to compatible Parquet types automatically.

Yes. Multi-table SQLite databases are supported. Each table becomes a separate record group in the Parquet file with preserved relationships.

The converter supports SQLite databases up to 500MB. Larger databases may need to be split into smaller files before conversion.

Parquet doesn't support database constraints like foreign keys or indexes. Only the data and basic schema are converted. Relationships are preserved as data references.

Parquet's columnar format enables faster aggregations, better compression, and efficient scanning of specific columns - ideal for analytical queries.

Yes. Parquet is the standard format for cloud analytics platforms like Snowflake, BigQuery, DuckDB, and Apache Spark.

BLOB columns are converted to Parquet's binary type. Most SQLite data types map cleanly to Parquet equivalents with preserved data integrity.

While not reversible through this tool, most data platforms can import Parquet files into new SQLite databases using ETL tools or scripts.

Conversion time depends on database size. Small databases (under 10MB) convert in seconds, while larger databases may take 1-2 minutes.

Yes. We generate standard Apache Parquet files compatible with all major analytics platforms, cloud services, and data processing frameworks.
