Size

width x height

• Height is optional, if no height is specified the image will be a square. Example: https://dummyimage.com/300
• Must be the first option in the url
• You can specify one dimension and a ratio and dummyimage will calculate the right value. Example: https://dummyimage.com/640x4:3 or https://dummyimage.com/16:9x1080

Colors

background color / text color

• Colors are represented as hex codes (#ffffff is white)
• Colors always follow the dimensions, https://dummyimage.com/250/ffffff/000000 not https://dummyimage.com/ffffff/250/000000
• The first color is always the background color and the second color is the text color.
• The background color is optional and defaults to gray (#cccccc)
• The text color is optional and defaults to black (#000000)
• There are shortcuts for colors
  • 3 digits will be expanded to 6, 09f becomes 0099ff
  • 2 digits will be expanded to 6, ef becomes efefef
  • 1 digit will be repeated 6 times, c becomes cccccc Note: a single 0 will not work, use 00 instead.
• Standard image sizes are also available. See the complete list.

Image Formats

.gif, .jpg, .png

• Adding an image file extension will render the image in the proper format
• Image format is optional and the default is a gif
• jpg and jpeg are the same
• The image extension can go at the end of any option in the url
  • https://dummyimage.com/300.png/09f/fff
  • https://dummyimage.com/300/09f.png/fff
  • https://dummyimage.com/300/09f/fff.png

Custom Text

&text=Hello+World

• Custom text can be entered using a query string at the very end of the url.
• This is optional, default is the image dimensions (300×250)
• a-z (upper and lowercase), numbers, and most symbols will work just fine.
• Spaces become +
  • https://dummyimage.com/200x300&text=dummyimage.com+rocks!
• The font used is from the freely available M+ Font Project

The following characters need to be encoded using the UTF-8 Hex version in order to be rendered properly.

You'll run into problems trying to manually enter a dimension as text if the numbers use the UTf-8 Hex values above, like &text=400x250. Use a multiplication symbol, × instead (not an x character) to get around this, &text=400×250.

If you need to use other unicode characters, look up their UTF-8 Hex version at http://www.fileformat.info/info/unicode/char/search.htm
