ICO File Viewer & Converter

Drop a .ico file to preview every embedded size, then download any of them as PNG, JPEG, or WebP. Runs locally in your browser — your file never leaves your device.

An .ico fileisn't a single image — it's a container that can hold multiple sizes of the same icon (16×16, 32×32, 48×48, 128×128, 256×256) at different colour depths. Windows picks the right size depending on where the icon is shown.

This tool reads the container, shows every embedded size as a preview, and lets you download any of them as PNG, JPEG, or WebP in one click. Nothing is uploaded — the entire conversion runs in your browser via the Canvas API.

About this ICO converter

ICO files are Windows' icon container — a single .ico can hold a dozen different versions of the same artwork at different sizes (16×16 for taskbars, 32×32 for desktops, 256×256 for tiles and high-DPI displays). When you double-click an .ico in File Explorer the OS shows the largest size, hiding the smaller ones; this tool unpacks every embedded image so you can see and use them all.

Every conversion runs entirely in your browser using the Canvas API and the browser's built-in image decoders. Your file is never uploaded to a server — no account, no signup, no watermarks. Download as PNG to keep transparency, JPEG for the smallest file (flattens to a white background), or WebP for the best compression at full quality.

The tool also accepts .cur cursor files — they use the same binary container as .ico with a different type flag, so all the same conversions work.

Frequently asked

What is an ICO file?▾

An ICO file is a container format used by Windows to store one or more icon images at different sizes and color depths (typically 16×16, 32×32, 48×48, 128×128, and 256×256). The operating system picks the size that best fits where the icon is displayed.

How do I convert an ICO to PNG?▾

Drop your .ico file onto this page. Pick the size you want from the sidebar. Click the PNG button. The file downloads instantly — no upload, no account.

Is this tool free?▾

Yes. Wallora's ICO converter is free to use forever, with no watermarks, no signup, and no upload to a server — the entire conversion happens locally in your browser.

Can I convert ICO to JPG or WebP?▾

Yes. Each embedded image can be downloaded as PNG (preserves transparency), JPEG (smallest for photos, no transparency), or WebP (smallest overall, supports transparency).

Are .cur cursor files supported?▾

Yes. Cursor files (.cur) use the same container format as .ico with a different type flag, so this tool reads and converts them identically.
