Convert PNG to Parquet

PNG (Portable Network Graphics) is a popular image format that keeps data quality while compressing files.

PNG files have some cool features:

• They compress without losing quality
• You can make parts of the image see through
• They support many colors (up to 48 bit true color)
• They work great for images with text, logos, or sharp edges

When we extract data from PNGs, they might contain:

• Screenshots of data tables or spreadsheets
• Graphs, charts, or other ways to show data visually
• Scanned documents or receipts

People often use PNG image data extraction for:

• Turning printed or handwritten data into digital form
• Getting information from charts and graphs
• Changing visual data into editable formats
• Automating data entry from image sources

By changing PNG images with data into formats like CSV or Excel, you can turn visual information into organized, analyzable data. Then you can process it more or use it in various data analysis tools.

Apache Parquet is a columnar storage format that works great with big data processing frameworks. It compresses and encodes data efficiently, which saves a lot of storage space and makes reading data faster.

Parquet can handle complex nested data structures. It lets you query and work with specific columns without having to read the entire dataset.

Compression

Parquet supports several compression algorithms like Snappy, Gzip, and LZO. These compression techniques help reduce storage space and speed up data processing tasks.
