PNG
PNG (Portable Network Graphics) is a widely-used raster image format that supports lossless data compression.
Key features of PNG files include:
- Lossless compression, maintaining image quality
- Support for transparency and alpha channels
- Wide color depth support (up to 48-bit true color)
- Excellent for images with text, logos, or sharp edges
When used for data extraction, PNG files can contain:
- Screenshots of data tables or spreadsheets
- Graphs, charts, or other data visualizations
- Scanned documents or receipts
Common use cases for PNG image data extraction:
- Digitizing printed or handwritten data
- Extracting information from charts and graphs
- Converting visual data representations into editable formats
- Automating data entry from image-based sources
By converting PNG images containing data to formats like CSV or Excel, you can transform visual information into structured, analyzable data for further processing or integration into various data analysis tools.
