SVG Slimmer

Traces a logo or icon, SVG or bitmap, as smooth curves, colour by colour, then checks the result against the original pixel by pixel so you can see what, if anything, was lost.

Open an SVG or PNG or drop it here, or paste SVG code

Quality

Sets detail, smoothing and small-shape protection together. Adjust any of them below.

Colours

Palette

Percentages are each colour's share of the artwork, background left out. Click a colour once to lock it in, so it stays however far you reduce Most colours. Click again to leave it out, and its pixels go to the nearest colour left; a third click hands it back. Faded colours were merged away: click one to bring it back, locked.

Traced as stacked layers, bottom first. Each layer runs under the ones above it, so no gaps open between colours.

Most colours24

For photos, gradients and AI images. The closest colours merge until this many are left; small distinct ones, like an eye, are kept.

Merge similar colours16

Colours closer than this are traced as one. Fewer colours make a smaller file.

Remove the background

Leaves out the colour around the artwork, such as a PNG's white background. The same colour inside the artwork, like white in an eye, is kept.

Fix blended edges

Where two colours meet, the soft pixels between them only take one of those two colours. Stops a fringe of a third colour, like pale grey along a dark edge.

Clean up edges0

Smooths out speckle and ragged edges from noisy or upscaled images before tracing.

Detailtrace grid

Pixels along the long side. Higher keeps finer detail and makes a bigger file.

Smoothing0.5

How far a curve may drift to merge into fewer, longer ones. opttolerance

Protect small shapes6%

Shapes smaller than this share of the image, such as eyes, letters and thin lines, are traced with almost no smoothing. Big curves still get the full amount.

Corners1.0

Lower keeps sharp corners, higher rounds them off. alphamax

Remove specks16 px

Any patch of colour smaller than this takes the colour around it, in the PNG and the trace. Measured at 2048 px across and scaled to the size you export.

Decimal places

that differs by at most %

Tries each detail and smoothing setting and keeps the smallest file that stays this close to the original.
