I have the following image which I want to remove only the fill which means colors, enter image description here

I want to convert this into the only outline image with using whatever tool could possible. I have already referred this Question but it doesn't work for me. Any kind of guidance will highly be appreciated.

    Hi. Welcome to GDSE. You don't need to recreate anything. The Sri Lankan flag is available as a vector graphic here: en.wikipedia.org/wiki/Flag_of_Sri_Lanka#/media/… - you can remove the fills in Illustrator

    There's nothing to show. You simply select the flag, and then set the fill to none, and stroke to black or whatever you want.

In Photoshop:

  • Convert the image in a Grayscale Mode
  • Press Cmd + Shift + L Mac or Ctrl + Shift + L Win to apply Auto Levels

Lyon b/W

  • Go to menu FilterOtherHigh Pass

High Pass

  • Make Auto Levels again
  • Press Cmd + L Mac or Ctrl + L Win to open the Levels Window
  • Double click the black Eyedropper and make sure is 100% black. Double click the white Eyedropper and make sure is 100% white
  • Use the Black Eyedropper to click a grey part of the image and the White Eyedropper to click the white. Repeat until getting the outline.


  • Press Cmd + I Mac or Ctrl + I Win to Invert

  • Go to menu ImageAdjustmentsThreshold to clean the image

  • Use the Eraser Tool and the Pencil Tool to clean up the details


In this final image the job is partially done, except the lion's head and legs.


I found this simple and easy to use tool online that does the job: https://vectordad.com/photo-to-outline/
