A computer-implemented technique can receive, at a computing device, a uniform resource locator (URL) for a web page and an image. A number of pixels corresponding to a desired resolution for encoding the image is determined and the image is converted to a modified image having the desired resolution. The technique can then generate a two-dimensional barcode by: (i) generating first data representative of the modified image, (ii) appending the first data to either an end of the URL to obtain a first modified URL or after a terminator bit of the two-dimensional barcode, (iii) generating second data representative of the second modified URL or the URL, and (iv) generating third data representative of an error correction code (ECC) based on the first data and the second data, wherein the two-dimensional barcode is generated based on the first data, the second data, and the third data.
