How to Blur Lines in Procreate
StyleFrame Team7 min read
To blur lines in Procreate, keep the line art on its own layer, tap Adjustments (the magic wand icon), choose Gaussian Blur, and slide your finger right across the screen to increase the softness. Tap the Adjustments icon again to commit. To soften only part of a line, select that area first, or use the Smudge tool with a soft brush at low opacity. For directional softness, Motion Blur and Perspective Blur are in the same Adjustments menu and use similar slide controls.
Blur a Whole Line Layer with Gaussian Blur
Gaussian Blur is the quickest way to soften line work. It affects the active layer, so the lines must be isolated from color, shading, and background.
- Open the Layers panel and tap the layer that holds your lines.
- Tap the Adjustments icon (magic wand) and select Gaussian Blur.
- Slide your finger right to add blur, left to reduce it. A blue "Slide to adjust" bar at the top of the screen shows the percentage, starting at 0%.
- Commit by tapping the Adjustments icon again, or tap the canvas and choose Apply if you want to stay in the effect and keep adjusting.
Keep the amount small. Lines are thin, high-contrast shapes, so even a modest blur lowers their density quickly. A few percent can be enough to remove a harsh digital edge. Heavy blur turns ink lines into faint smears, and you can't recover the original weight once you commit and keep working.
Gaussian Blur does not work while you are 3D painting. If the adjustment seems unavailable, check whether you're in a 3D painting session.
Duplicate first
Before blurring, duplicate the line layer. Blur the copy and leave the original untouched. This gives you:
- A safe fallback if the blur goes too far.
- The option to lower the blurred layer's opacity and blend it with the sharp one for a soft-focus look.
- A cheap glow effect: duplicate the layer, blur one copy, and place it over a dark background while the sharp version stays on top.
The glow trick can be used for artwork like stars and fireworks. It's the same idea of blurring a duplicate while the crisp version stays on top.
Blur Only Part of a Line
Applying one adjustment to a whole layer is blunt. Often you want a line to dissolve at one end, soften behind a foreground object, or fade into shading. Procreate offers two practical routes.
Option 1: Select, then blur
Use the Selection tool (the S icon) to draw around the region you want to soften, then apply a slight Gaussian Blur. The adjustment affects only the selection.
Hard selection edges can leave a visible seam where blurred and sharp areas meet, so keep the blur slight. This is the most predictable approach if you need a controlled result. It's also slower than painting, which is the main complaint from artists who want a true "blur brush."
Option 2: Use the Smudge tool as a softener
Procreate has no dedicated blur brush, so many artists use the Smudge tool instead:
- Choose a soft brush for smudging, such as a soft airbrush.
- Keep the size small and the opacity low.
- Work in short strokes along the line, not across it.
- Lower brush spacing if the effect looks patchy.
The catch is that Smudge pulls color from neighboring pixels. If the surrounding area is a different color, you'll drag that color into the line. Isolating the lines on their own transparent layer avoids this. Smudge then only has your line pixels to work with, so it softens them without picking up background color.
Third-party blur brushes exist on the Procreate marketplace if you want a one-tap option, but the built-in methods above cover most cases.
Directional Softness: Motion Blur and Perspective Blur
Not every blur should be uniform. Procreate includes two directional options under the same Adjustments menu.
Motion Blur creates a streaky smear. Slide your finger in the direction you want the streak to go. A diagonal drag creates a diagonal blur. This suits speed lines, trailing strokes, or the sense that a line moved during an exposure.
Perspective Blur radiates blur from a movable point, shown as a disc on the canvas. Drag the disc to set the origin, then drag outside it to set intensity. It has two modes:
- Positional radiates blur outward from the disc in all directions.
- Directional radiates it from one side of the disc only.
Both are useful for zoom-burst and "blast" effects. Like Gaussian Blur, they don't work during 3D painting.
Fixing Common Problems
The blur affects everything, not just the lines. The adjustment applies to the active layer. Check that lines are separated from fills and backgrounds. If they're merged, select the region or redraw the lines on a new layer.
Lines fade away instead of looking soft. Thin strokes lose density as they spread. Try a smaller amount, then restore weight by duplicating the layer and stacking the copies, or by blending the blurred and sharp versions.
The result looks pixelated or mushy. Low canvas resolution makes blurred lines look worse. Start at a larger canvas size if the artwork will be scaled up or used in video.
Smudge leaves color fringes. Move the lines to an empty layer. Otherwise, keep Smudge strokes small and gentle.
You can't undo a committed blur several steps later. Duplicate the layer first so you always have the sharp original to return to.
When Lines Leave Procreate for Motion Work
For motion designers and animators, hand-drawn line work often becomes one asset inside a larger comp. That changes the decision about where to blur.
Blurring inside Procreate bakes the softness into the pixels. That's fine for a final illustrated look. If the amount might change, or the line needs to animate in or out of focus, it's usually smarter to export the lines sharp and blur them downstream in your compositing or 3D software, where blur amounts can typically be animated.
A practical handoff from Procreate:
- Export lines on a transparent background and keep layers separate.
- Keep a sharp version and a pre-blurred version if you're unsure which the comp will need.
- Name layers clearly, since they're easier to manage once they become footage layers.
- Keep the canvas large enough to survive the scale and crop of your final timeline.
Where Styleframe fits
Blurring softens lines, but sometimes the real goal is a consistent line style across many frames, and manual blur on every frame won't get you there. Styleframe is an AI video and motion tool built around artistic control. It uses reference images and clips to drive style transfer, so you can steer toward a drawn, inked look instead of settling for a one-click result. Your Procreate drawings can act as source material for generated motion.
Styleframe doesn't replace Procreate's drawing tools or a compositor's blur nodes. It's useful when you want your illustrated line quality to carry into moving footage with more control than a manual frame-by-frame approach.
Quick Reference
Final Tips
- Always blur lines on their own layer.
- Duplicate before you commit.
- Use small amounts, then build up.
- Keep blur on selections slight to avoid visible seams.
- Decide early whether the blur is a final look or something your compositor should control.
Procreate's blur tools are simple, but the choices around layers and export matter more than the slider itself. Set those up well and the softening is easy to refine, whether the artwork stays a still or becomes part of a motion piece.
