Why convert PNG to ICO?
An ICO file is not just a renamed PNG. It is the Windows icon container that bundles several resolutions in one file, so a single ICO can stay crisp as a 16px browser-tab favicon and as a 256px desktop shortcut alike. This tool uploads your PNG to our secure server, packs the standard icon sizes into a true multi-resolution ICO, preserves the alpha transparency, and deletes the file right after. Free, no sign-up, no watermark. Drop the result at your site root as favicon.ico or reuse it as a Windows app icon.
- You designed a logo or app mark as a transparent PNG and need a favicon.ico to place at your website's root, so every browser, including older ones that ignore PNG link tags, shows your tab icon.
- You are packaging a Windows desktop app or shortcut where the build tooling or the Properties dialog only accepts a multi-size .ico for the executable and Start menu icon.
- A CMS, installer, or legacy admin panel rejects your PNG and demands an ICO upload, so you need a fast, faithful conversion that keeps the transparent edges intact.
PNG vs ICO
PNG · Portable Network Graphics
PNG is a lossless raster format with full alpha transparency. It keeps text and sharp edges crisp, which makes it ideal for logos, icons, screenshots and UI graphics — at the cost of larger files for photographs.
ICO · Windows Icon
ICO is the Windows icon/favicon container, holding several small sizes in one file. Convert to and from PNG when making favicons or app icons.
PNG to ICO — frequently asked questions
Does the converter keep my PNG's transparent background?
Yes. ICO supports a full 32-bit alpha channel, so the transparency in your PNG carries straight through. Soft anti-aliased edges and rounded corners stay clean against any tab color or desktop wallpaper, with no white box behind the icon.
What size should my source PNG be?
Start with a square PNG, ideally 256x256 or larger (512x512 is great). A square source scales down cleanly into the smaller sizes packed inside the ICO. Non-square images still convert, but they can look stretched or letterboxed once squeezed into a square icon slot.
Browsers accept PNG favicons now, so do I still need an ICO?
For modern browsers a linked PNG or SVG works fine, but favicon.ico stays the universal fallback. Browsers automatically request it from your domain root even with no link tag, and legacy environments still expect it, so a proper ICO is the safest cross-platform choice.
How do I convert PNG to ICO?
Drop your PNG file (or several) into the converter, confirm ICO is selected as the output, click convert, then download the ICO file. The whole thing takes a few seconds.
Is this PNG to ICO converter free?
Yes — it's completely free with no watermark and no sign-up required.
Is it safe to convert PNG to ICO here?
Yes. Your PNG file is sent over an encrypted HTTPS connection to our conversion server, converted, and deleted automatically moments later — it is never stored, logged or shared.
Can I convert multiple PNG files at once?
Convert one PNG file at a time — finish one, then drop in the next.
Does it work on mobile?
Yes — the converter runs in any modern browser on phones, tablets and desktops.
