How do I convert a PDF to an ICO icon?

Upload your PDF, choose a page or range (or let the tool take the first page), then select output sizes (the default covers 16, 32, 48, and 256 px). Our converter rasterizes the vector content at 300 DPI for sharp edges, merges them into a single multi-page ICO, and lets you download the file. For best results, make your design square with a transparent background before uploading.

Why would I need to convert a PDF to an ICO?

PDFs are great for print and document sharing, but Windows icons and web favicons require the ICO format. ICO supports multiple embedded resolutions and alpha transparency, so a single file can serve as a crisp app icon on high-DPI displays. Converting a vector PDF ensures your logo or design scales down to 16x16 without distortion — far better than using a JPEG or PNG that may not include the same vector sharpness.

What happens to transparency and vector quality when converting PDF to ICO?

The converter rasterizes each PDF page into a high-resolution bitmap, preserving alpha-channel transparency. Vector shapes and lines are smoothed, but they become pixel-based, so text and paths are no longer editable. DPI is locked to 96 for icon use, and all sizes are generated from the same master raster to keep the appearance consistent. If your PDF has multiple pages, only the selected page is converted by default, so be sure to pick the correct one.
