An ICO can contain several sizes — which one do I get?

A .ico file is a container that can hold multiple icon sizes (16×16, 32×32, 48×48, 256×256…). This tool extracts the largest icon inside and saves it as a PNG.

Is transparency preserved?

Yes. Icon transparency (the alpha channel) is kept intact in the PNG output, so the image keeps its transparent background.

Are my icon files private?

Yes. Files are uploaded over HTTPS, converted outputs are auto-deleted within 24 hours, and uploaded inputs are removed within 6–24 hours.

What limits should I know about?

Anonymous users: 20 MB files and 1 free server conversion. Free accounts: 50 MB, 3 conversions per 30 days, batches of 5. Paid: 200 MB and batches of 100.

Can I batch-convert multiple ICO files at once?

Yes. Free accounts can batch up to 5 files at a time; paid accounts up to 100. Anonymous users get 1 free server conversion.

Where do .ico files usually come from?

Common sources include website favicons, Windows application and shortcut icons, and icon packs extracted from executables — all can bundle several sizes in one file.

Can I pick a smaller size instead of the largest?

Not currently — the tool always extracts the biggest icon in the container automatically for the best possible quality. If you only need a small size, resize the resulting PNG afterward.

About the formats

ICO

ICO is the Windows icon format, best known today as the container behind website favicons. A single .ico file can hold the same image at several sizes — commonly 16, 32, and 48 pixels — so the system can pick the right one.

For favicons, ICO still has the broadest compatibility: browsers request /favicon.ico by default, and even very old clients understand it. The format tops out at 256 x 256 pixels and is not meant for photos or general images. Modern sites often add PNG or SVG icons alongside, but shipping a classic ICO remains the safe baseline.

PNG

PNG is a lossless raster image format created in the mid-1990s as a patent-free replacement for GIF. It is the standard choice for screenshots, logos, UI graphics, and any image that needs transparency.

PNG preserves every pixel exactly and supports a full 8-bit alpha channel, so text and sharp edges stay crisp. The downside is size: photographs saved as PNG are far larger than the same image as JPG or WebP. Support is universal in browsers and editors, making it a safe default for graphics — just avoid it for large photo collections.

Troubleshooting

The PNG is smaller than expected: The tool exports the largest icon stored in the file. Many .ico files only contain small sizes (16×16 or 32×32), so the PNG cannot be bigger than what the container actually holds.
My file won't upload: Check that the file is a genuine .ico container. Some favicons found online are actually PNG files renamed to .ico — if yours is one of those, it is already a PNG and just needs the extension fixed.
The image looks jagged when enlarged: Icons are tiny bitmaps, and upscaling cannot invent detail that was never there. Use the PNG at its native size, or track down a higher-resolution source of the artwork.
