PNG to Base64

Convert PNG to Base64 online and use it as a generator, which provides ready-made examples for data URI, img src, CSS background-url, and others. The PNG to Base64 converter is identical to Image to Base64, with the only difference that it forces the mime type to be “image/png” (even if the uploaded file has a different content type or it cannot be detected). Please note that the PNG to Base64 encoder accepts any images types with a size of up to 50 MB. If you are looking for the reverse process, check Base64 to PNG.

Output formats

If you do not know what output format you need, check the following examples to see how will look the result of the same Base64-encoded PNG image formatted in each of the available formats (as an example image I use a one-pixel red dot PNG file):

If I missed an important output format for Base64-encoded PNG images, please let me know — I would love to implement it.
