Procreate Pixel Art Brush
Updated!
I recommend making a canvas that's 50px to 100px on the wider side, for best results but feel free to experiment!
With this brush, you will be able to create nice and crisp pixel art! I like to create cute little pixel objects and characters.
To upsize big for export without getting aliasing:
1. If you want to keep original, Duplicate document
2. Action -> Canvas -> Crop and Resize
3. Increase document size, and keep them at the same shape by clicking the symbol in between the numbers. Do not select “Resample”.
4. Your drawing will be very small now in a big canvas
5. Merge layers together
6. Select the new layer
7. Press the arrow selector icon
8. Make sure 'Nearest Neighbor' is selected at the bottom of the screen for pixel interpolation.
9. Select “Fit Screen” or choose the uniform mode and change your drawing to the desired size
10. Your image is now ready, preserving those hard pixel edges. You can now export it in whichever format you wish.
