XLSX to FLIF Conversion
What are XLSX files?
XLSX is the standard Microsoft Excel spreadsheet file, in use since Excel 2007. It stores workbooks with one or many sheets of tables, numbers, text, dates, formulas, charts, pivot tables, and formatting. A sheet can hold more than a million rows, the files are compact, and they open on Windows, Mac, phones, and in online services, and many programs can read and write them. XLSX is the usual format for budgets, price lists, reports, and data exchange.
What are FLIF files?
FLIF (Free Lossless Image Format) is a royalty-free format launched at the end of 2015 as "work in progress" with the aim of offering a better alternative for storing lossless images than the existing PNG, WebP, BPG, JPEG2000 and JPEG XR. FLIF provides similar image quality as the other extensions, but in a file size than can be up to 74% smaller. The new format uses a form of the Adam7 algorithm for compressing images, offering progressive interlacing that allows users to obtain a reasonable encoding of an image even from a partial download.
