Turning a Photograph into a Polka Dot Image in GIMP
This a very quick simple tutorial and a bit of fun! I have made a range of different sizes – 50px, 75px, 100px, 150px patterns so you can easily apply the effect in seconds. I suggest you try some masking of layers as well to experiment with design :).
1. Making a Polka Dot Stencil
- Create a new document in GIMP – choose the size of your Polka Dot (I have ready made ones to download at the end of the tutorial), Fill with: Transparency, 72 resolution should be fine:
- Grab the Ellipse Tool, fill the square with the a circle:
- Invert the selection, Ctrl + I or Select –> Invert:
- Grab the Paint Fill Tool, Fill Whole Selection with Black or White:
- Save this as Pattern file .pat!
- Then copy it into your Patterns Folder – C:\Program Files\GIMP-2.0\share\gimp\2.0\patterns (Could be different).
2. Pixelize
- Open your photograph in GIMP – Duplicate your image if you’d like to do some Layer Masking later!
- We need to pixelize the photograph to get the single solid colours for each dot – Go, Filters –> Blur –> Pixelize:
- Now choose the size of your pixels – depends on the Polka Dot size you want (50, 75, 100, 150, custom)
3. Applying Polka Dot Pattern
- In your Patterns Toolbar select the Polka Dot stencil you want to use (mine will be 74px BLACK):
- Now go, Edit –> Fill with Pattern (Ctrl +;):
4. Cropping Excess
- Your image and pattern will not always fit perfectly so a little cropping is needed.
- Just crop to the edges of the dots:
5. Saturation
- I recommend a little saturation to boost the effect!
6. Download Patterns
- You may download the Polka Dot Patterns here:
Black and White (50, 75, 100, 150):

- polka-50-WHITE.pat 9.8K
That’s It!

If I sent you a picture to make into colored dots (I want the dots the size of a single Mardi Gras bead) and the overall picture to be 30 inches wide and 20 inches high. (poster size) I only want the people color dotted. I am going to fill in the background with Mardi Gras beads. I need ASAP! Thank you!
Thank you for this.
Yeah, it is alright :P
Thanks for the link.
I didn’t know that there is gimp for osx, only knew of the Linux and Windows versions.
Hi Danilo,
Unfortunately I do not use Linux! This tutorial was done on OSX :)
There is an OSX theme for Linux here – OSX Tiger!
Hello!!!
Sorry about my English (I’m brazilian)
Please tell me what’s the gtk theme you use.
Ah yes, that is another good effect! They should consider putting in this Polka Dot effect too in the next release :) !
Have a look at the ‘mosaic’ filter for a similar effect.
