To select a logo on a scan in Photoshop, first clean up and boost the contrast of a copy of the scan. Then choose a selection method that suits the artwork. Use Select > Color Range for a flat one- or two-color mark, the Magic Wand with Contiguous turned off for crisp solid shapes, or a channel-based selection when the ink is faint or the paper is uneven. Refine the edge in Select and Mask, output the result as a layer mask, and check it against contrasting backgrounds before you use it.

Keep in mind what that selection is. In Photoshop, a selection is a marked area of pixels, and a layer mask is a grayscale map that hides or reveals parts of a layer. Both are raster: they are built from pixels at the scan's resolution. A vector logo is built from mathematically defined paths, which are lines and curves joined at anchor points, so it can be scaled without losing quality. A good Photoshop selection gives you a clean, isolated version of the logo. It is the right starting point for redrawing, but it is not a vector file.

Before you start: what this guide can and cannot settle

No details about a specific scan were provided, such as its resolution, colors, paper condition or intended output. This guide therefore gives no fixed slider values or resolution targets. Treat any settings you choose as adjustments to judge by eye on your own file. Menu names and tool availability also vary between Photoshop versions. If a command is missing, look for it in the Select menu or the tool's options bar.

Being able to isolate a logo does not give you the right to reuse it. Confirm you have permission from the logo's owner before you reproduce or redistribute the artwork.

Step 1: Prepare the scan

  • Duplicate the background layer and work on the copy so the original scan stays intact.
  • Crop to the logo with some margin, and use the Crop tool's straighten option if the print was scanned at an angle.
  • If color is not needed to tell parts of the logo apart, convert a copy to grayscale. This simplifies the tonal range.
  • Use Levels or Curves to push the paper toward white and the ink toward solid color. The aim is a clear tonal gap between logo and background.
  • Remove dust, specks and scratches with the Spot Healing Brush. Filters such as Dust & Scratches can soften fine detail, so use them sparingly.

Step 2: Choose a selection method

Logo condition | Suggested method | Why it fits
Single flat color on light paper | Select > Color Range, sampling the ink | Selects every pixel of that color at once, including separate letters and enclosed shapes
Crisp, solid shapes with clean edges | Magic Wand with Contiguous unchecked | Quick for high-contrast artwork; with Contiguous off it also catches isolated parts
Several distinct colors | Color Range for each color, combined with Shift or saved as separate selections | Keeps color areas separate, which helps when redrawing them as separate shapes
Faint ink, uneven paper or show-through from the reverse side | Channel-based selection | Uses the channel where the logo contrasts most with the paper
Logo set among other printed content | Object Selection or Select Subject, then refine | Gives a quick overall outline to tidy by hand

In Color Range, the Fuzziness slider sets how far from the sampled color a pixel can be and still be included. Raise it until the whole logo is selected, and stop before paper texture starts to appear in the preview. Add samples with the plus eyedropper if parts of the ink are lighter than others.

Step 3: Use a channel selection for difficult scans

  • Open the Channels panel and click through the color channels. Find the one where the logo looks darkest against the lightest background.
  • Duplicate that channel. Edits to the copy will not change the image.
  • Apply Levels or Image > Adjustments > Threshold to the duplicate channel, pushing the logo to black and the paper to white.
  • Paint out leftover marks with a black or white brush as needed.
  • Ctrl-click (Windows) or Cmd-click (macOS) the channel thumbnail to load it as a selection. White areas load as selected, so invert the selection if the logo is black.

Threshold turns every pixel either black or white based on a single cutoff point. That makes it useful for one-color logos. It can, however, thicken or thin strokes and close up small gaps depending on where the cutoff sits, so compare the result with the original scan.

Step 4: Refine the edge

With the selection active, open Select and Mask. Use the view modes to preview the edge on black, white or a layer, and adjust these controls:

  • Smooth reduces jagged, irregular edges caused by paper grain and halftone dots.
  • Contrast sharpens a soft edge.
  • Shift Edge moves the edge inward to remove a light fringe or outward to recover thin strokes.
  • Feather blurs the edge. Leave it at or near zero if you plan to trace the logo, because a soft edge makes curves harder to judge.

Output the result as a layer mask instead of deleting pixels. A mask can be corrected later with a brush, while deleted pixels cannot be restored.

Step 5: Verify the selection

  • Place a solid-color layer in a strongly contrasting color beneath the logo, then switch to the opposite tone. Halos and leftover paper show up quickly this way.
  • Zoom to 100% and closer, and pan along every edge.
  • Check the counters, which are the enclosed spaces inside letters such as o, a, e and d. They should be cut out, not filled with paper.
  • Check thin strokes, serifs, small text and trademark symbols. These are the first details to vanish or merge.
  • Shift-click the mask thumbnail to switch the mask off, and compare the masked result with the original scan.
  • Compare the overall proportions with the printed original, or a cleaner reference if one exists. Strokes may have swelled or eroded during contrast adjustments.

Step 6: Turn the selection into usable artwork

For on-screen or placement use at a similar size, save the layered file as PSD. Export a PNG if a transparent background is needed. The quality is still limited by the scan's resolution, so the logo will not stay sharp when enlarged.

For scalable artwork, you need to redraw the logo. Photoshop can turn a selection into a work path through the Paths panel's Make Work Path command. File > Export > Paths to Illustrator then saves that path for use in a vector editor. Paths converted from scans usually have too many anchor points and wobbly curves, so treat them as a rough guide. Most professional reconstructions place the cleaned image as a template and redraw the shapes with the Pen tool. That allows straight lines to be truly straight, curves to be smooth, and repeated elements to match. Automatic tracing tools can speed this up but need the same cleanup.

Whichever route you take, the file extension alone does not confirm the result. An AI, EPS, PDF or SVG file can still contain embedded pixels. Open the file and inspect it in outline view before calling the logo vector artwork.
