What is the difference between Low, Medium, and High?

Low keeps most of the original detail and just softens minor noise and texture. Medium merges small color variations into broader shapes, useful for planning your first blocks of paint. High pushes further into bold, abstracted color regions, which is handy for busy references or a more graphic, simplified painting style.

What do the Custom radius and strength settings control?

Radius controls how large an area is sampled when deciding what counts as one color region, so a bigger radius merges more of the photo into fewer, larger shapes. Strength controls how aggressively color is smoothed within those regions once they're defined. Adjusting them separately gives you far more control than the fixed presets alone.

Will simplifying lose important details from my reference?

Key edges are preserved on purpose, so the outlines that define your subject stay sharp even at higher simplification levels. What gets smoothed out is mostly internal texture and small color noise, the kind of detail that's hard to paint accurately anyway and rarely matters for the final piece.

Can I combine simplification with the sketch outline tool?

Yes, and the two work well together. Generate a sketch outline first to capture the clean edges of your subject, then layer a simplified version underneath to plan your color blocks. Together they give you both the "where the lines go" and the "what color goes where" in one reference.

Is the simplify tool free to use?

Yes, completely free, with no account, no signup, and no ads. All the processing happens locally in your browser, so nothing you upload leaves your device.

Does this use AI to generate the simplified image?

No. It's mathematical image processing that analyzes color regions in your photo, not a generative model creating new content. The result is always derived directly from your own reference photo.

Can I still use a grid after simplifying my reference?

Yes. Grids, sketch outlines, and simplification all apply to the same reference photo at once, so you can overlay a grid on top of a simplified image to keep your color blocks in proportion as you transfer them to canvas.

Simplify Color and Details for Painting

Reduce a busy reference photo into clean color shapes while key edges stay sharp, from subtle guidance to bold abstraction. Plan your color blocks before a single brushstroke touches the canvas. No accounts, no ads, completely free.

Before

After

Edge-Aware Smoothing

Color is smoothed within regions, not across them, so the outlines that define your subject stay sharp without becoming a blur.

Low, Medium, High

Three ready-made levels take you from a light cleanup of noisy detail to a fully abstracted, graphic color map.

Custom Radius & Strength

Dial in the exact region size and smoothing strength yourself, for control the presets alone can't give you.

Fewer Shapes, Same Subject

A busy photo can be intimidating to start from, full of small color shifts that don't actually matter to the final painting. This tool groups nearby colors into broader regions and smooths within them, while leaving the strongest edges alone, so what's left reads like a painter's first block-in pass rather than a blurred photo.

Presets for Speed, Custom for Control

Low, Medium, and High cover most references without any fiddling. When a photo needs something in between, or something more extreme, switch to Custom and adjust two independent controls until the result matches what you have in mind.

Radius

Sets how large an area is considered when grouping colors together. A smaller radius keeps more localized detail, a larger one merges the photo into fewer, broader shapes.

Strength

Sets how aggressively color is smoothed once regions are defined. Push it further for bold, poster-like abstraction, or keep it light for a subtle cleanup.

More Reference Photo Tools

Simplification is one piece of preparing a reference photo. Canvasthing also scales a drawing grid to your real canvas size, generates a clean sketch outline to trace from, and lets you sample exact colors for easier paint matching.

Grid Method

Overlay a scaled drawing grid on your reference photo to keep proportions accurate as you transfer it to canvas.

Outline Sketch

Generate a clean, pencil-style line art outline from any reference photo, ready to trace and pair with simplified color.

Inspect Colors

Pick any point on your reference photo to sample, enlarge, and study that color so you can match it by eye.

Frequently Asked Questions

It reduces a busy reference photo down into clean, simplified color regions, similar to how a painter blocks in the big shapes before adding detail. Instead of blurring the whole image, it smooths color within regions while keeping the strongest edges intact, so the simplified version still reads clearly as the same subject.
