Convert Pixel Logos to Vectors in GIMP

Converting low-resolution pixel logos into sharp, infinitely scalable vector graphics is entirely possible in GIMP through thresholding and path tracing. This tutorial outlines the exact step-by-step process of importing a raster logo, isolating its shapes by forcing pixel data into crisp black-and-white boundaries using the Threshold tool, generating vector paths from that selection, and exporting the final result as a scalable vector graphic (SVG) file.

Step 1: Prepare the Source Image

Open your low-resolution logo in GIMP by navigating to File > Open. If the logo is small (e.g., under 500 pixels wide), increasing the canvas size helps GIMP generate smoother paths.

  1. Go to Image > Scale Image.
  2. Increase the width and height by 200% to 400%, setting the Interpolation method to Cubic or NoHalo.
  3. Click Scale.

This step softens harsh pixelation into a gradient of tones, which the Threshold tool can evaluate more effectively.

Step 2: Apply the Threshold Tool

Low-resolution images often contain compression artifacts, blurred edges, and anti-aliasing. The Threshold tool eliminates these intermediate colors, flattening the graphic into pure black and pure white.

  1. Go to Colors > Desaturate > Desaturate to remove any color information, choosing the Luminance mode.
  2. Go to Colors > Threshold.
  3. In the Threshold dialog, drag the black and white slider handles until the logo shapes appear solid and the edges are as clean as possible.
  4. Balance the slider to eliminate unwanted noise while retaining the original geometric proportions of the logo.
  5. Click OK to commit the changes.

With the artwork converted to high-contrast black and white, you can now select the geometry precisely.

  1. Select the Select by Color Tool from the Toolbox (or press Shift + O).
  2. In the Tool Options panel, set the Threshold to 0 and ensure Antialiasing is unchecked.
  3. Click directly onto the black portion of your logo to create an active selection around all shapes.

Step 4: Convert the Selection to a Vector Path

GIMP includes a built-in algorithm that traces active selection boundaries and translates them into mathematical Bezier curves.

  1. Open the Paths dialog. If it is not visible, go to Windows > Dockable Dialogs > Paths.
  2. Go to the top menu and select Select > To Path, or click the Selection to Path button located at the bottom of the Paths panel.
  3. Deselect the active marching ants by pressing Ctrl + Shift + A (or Cmd + Shift + A on macOS).
  4. Click the eye icon next to the newly created path in the Paths dialog to make the red vector outline visible on your canvas.

Step 5: Clean Up and Refine Paths

  1. Select the Paths Tool from the Toolbox (press B).
  2. Click directly on the vector path visible on the canvas.
  3. Inspect the vector nodes (anchors). Click and drag individual nodes to reposition them, or adjust the directional handles to smooth out any irregular curves left by the pixel tracing process.
  4. To delete unnecessary nodes that cause bumpy edges, hold Ctrl + Shift and click the unwanted node.

Step 6: Export to SVG

Once your paths are smooth and accurate, export them for use in vector editors like Inkscape or Illustrator:

  1. Right-click the path layer in the Paths dialog.
  2. Select Export Path....
  3. Choose your destination folder, name the file with the .svg extension (e.g., logo-vector.svg), and click Save.

Your raster logo is now converted into an editable, resolution-independent SVG vector file.
