FAQ
XLS to FLIF Conversion
What are XLS files?
XLS is the older Microsoft Excel spreadsheet file. It was the standard format of Excel from version 97 to Excel 2003, and it stores tables with numbers, text, dates, formulas, charts, and formatting, in one or several sheets. Modern Excel still opens it, but new files are saved as XLSX, which is smaller and holds far more data. A great number of price lists, reports, and accounting tables made before 2007 are still XLS files.
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.
