ConvertIcon Desktop: Fast Batch ICO & PNG Converter

How to Use ConvertIcon Desktop to Create Windows Icons

Creating high-quality Windows icons from PNG, SVG, or other image formats is quick with ConvertIcon Desktop. This guide walks through the process step-by-step, plus tips for multi-size icons, transparency, and common settings.

What you’ll need

• ConvertIcon Desktop installed on Windows
• Source image (PNG, SVG, BMP, JPEG). For best results use a square image with a transparent background at 512×512 or larger.

Step 1 — Open ConvertIcon Desktop

Launch the app. The main window shows a simple drag-and-drop area and toolbar with options for output formats and sizes.

Step 2 — Import your source image

• Drag your PNG/SVG into the workspace or use File → Open.
• If using multiple source images, import them all; ConvertIcon can batch-process into separate .ico files.

Step 3 — Choose icon sizes

• Recommended set: 16×16, 24×24, 32×32, 48×48, 64×64, 128×128, 256×256.
• For Windows ⁄₁₁, include 256×256 (PNG-compressed) for best scaling.
• In the Sizes panel, check the sizes you need or enter custom dimensions.

Step 4 — Configure transparency and background

• If your source has transparency, ensure the “Preserve alpha” or “Keep transparency” option is enabled.
• To add a background color, choose Background → Color and pick a solid color (useful for non-transparent PNGs).

Step 5 — Adjust image scaling and alignment

• Use the Fit, Fill, or Stretch modes:
  • Fit: keeps aspect ratio with empty padding if necessary.
  • Fill: crops to fill square icon area.
  • Stretch: force-fits to square (may distort).
• Center the image or adjust alignment offsets if needed.

Step 6 — Preview each size

Check the preview thumbnails for each selected size. Confirm there’s no unwanted pixelation or clipping at small sizes (16–24 px); simplify or retouch the source if necessary.

Step 7 — Export to .ico (single file with multiple sizes)

• Click Export → Save as ICO.
• Choose output filename and destination.
• Ensure “Include selected sizes” is checked so the .ico contains multiple resolutions.

Step 8 — Create individual PNGs (optional)

If you need separate PNG files for each size:

• Choose Export → Save as PNGs.
• Select a destination folder; ConvertIcon will create one PNG per chosen size.

Batch conversion (multiple inputs)

• Drag multiple source images into the workspace.
• Configure sizes and settings once, then use Batch Export → Save all as .ico to produce one .ico per source image automatically.

Tips for best results

• Design a simplified version for very small sizes (16–24 px); intricate details don’t scale down well.
• Use high-contrast shapes and clear silhouettes for legibility at small sizes.
• Export a 512×512 or 256×256 source with transparency to give Windows a crisp icon for high-DPI displays.
• Test the icon by right-clicking a shortcut → Properties → Change Icon → Browse and select your .ico file.

Troubleshooting

• Blurry icons at small sizes: create simplified artwork for those sizes or adjust hinting/sharpness in an image editor before conversion.
• Transparency lost: re-check “Preserve alpha” and confirm source file actually has transparent pixels.
• Colors shift: ensure you’re using sRGB PNGs; ConvertIcon should preserve colors but some editors change color profiles.

Quick workflow summary

1. Open ConvertIcon Desktop → import image.
2. Select recommended sizes (include 256×256).
3. Preserve transparency and choose scaling mode.
4. Preview, then Export → Save as ICO.
5. Test the .ico in Windows.

That’s it — with these steps you can produce professional Windows icons quickly using ConvertIcon Desktop.
