Free Online GIF to Data Uri (TXT) Converter

GIF files have been around since the mid-to-late 1980's and were introduced by CompuServe as a way to compress color images into small file sizes suitable for downloading which at the time most download speeds were limited. The format allows varying size color palettes up to 256-colors in total to be defined from a palette of 16 million colors.

Later on the ability to add animations to the GIF file format was added. GIF files became a popular image file format for the early internet due to the small size, large color palette and animation capabilities and is still popular today.

The Data Uri TXT file format is a method of embedding external webpage resouces such as images directly into the HTML markup. The benefit of embedding external resouces reduces HTTP requests for a webpage thus reducing the overall load time.

Data is encoded using the Base64 method of encoding binary data as text using ASCII characters. Due to the encoding method the resulting file size will be around 33% larger than the binary equivalent so there is a trade-off between the number HTTP requests and the increase in request size.
