Add the ICO file
Drop, paste, or choose the ICO icon. Fileverses attempts a local browser decode; if that ICO cannot be read, export the representation you need as a browser-readable raster image with icon-capable software first.
Free online ICO to PNG converter
Save a decoded ICO icon as PNG,locally in your browser.
Fileverses attempts to decode a browser-readable ICO locally, draws the rendered image to a canvas, and asks the browser for a PNG. The PNG encoding is lossless for those canvas pixels, including decoded alpha values where present; it is not a byte-for-byte ICO conversion or a way to choose an icon entry.

About this converter
Free ICO to PNG conversion, built for a real workflow.
ICO is an icon container commonly used for Windows icons and favicons, and it can contain more than one image representation. PNG is a single raster image with lossless encoding. Fileverses attempts to decode a direct ICO upload with the browser, then draws the one rendered result to a canvas and encodes that canvas as PNG. The route has no control for choosing, extracting, combining, or preserving individual ICO entries, so the browser-decoded result—not a user-selected container image—is what becomes the PNG. PNG encoding is lossless for the decoded canvas pixels. It can carry decoded alpha values, including semi-transparent pixels at icon boundaries, when the rendered result has them; it does not create alpha, crop the icon, remove or replace a background, or repair edge detail. This is raster output, not vector recovery, editable artwork, an application-bundle workflow, or recovery of original ICO bytes. A browser that cannot decode a particular ICO cannot convert it here; export the intended icon image with icon-capable software first. Keep the original ICO when another representation may be needed, and inspect dimensions, visible edges, alpha, and final file size in the destination workflow.
- Fileverses attempts to decode a direct ICO upload with the browser and uses its one rendered image. It does not offer ICO-entry selection, extraction, combination, or preservation, so choose and export a required representation in icon-capable software first when that control matters.
- The browser draws the decoded image to a canvas and encodes that canvas as PNG. Lossless describes the PNG encoding of those canvas pixels; it does not mean original ICO bytes, alternate entries, or missing image detail are recovered.
- PNG can represent decoded alpha values, including partially transparent edge pixels. The converter does not create transparency, crop artwork, remove a background, or replace a background, so review the rendered icon before and after download.
- The download is one raster PNG, not vector artwork, editable paths, layers, or an application bundle. It cannot sharpen a small or soft icon, recreate vectors, or improve image quality.
- A particular ICO must be browser-readable to convert. You can queue up to 50 files under 50 MB each, and a decoded image over 12 megapixels is rejected. Final PNG size is not guaranteed; check the download in its intended destination.
How it works
Upload once.
Export PNG.
Keep PNG selected
PNG is selected on this route. The page uses the browser-rendered ICO result and does not let you select, extract, or combine entries from the ICO container.
Download and inspect
Save the lossless browser-canvas PNG, then inspect its dimensions, visible alpha boundaries, and file size in the app or site where you plan to use it.
Made for real pipelines
ICO to PNG.
One workspace.
Convert without uploading your assets. Switch outputs anytime — web, print, icons, and document targets from the same batch.
Convert ICO to PNGBrowser-decoded ICO input
Attempt a local browser decode of a direct ICO upload. The page uses one rendered result and does not expose selection or extraction of individual container entries.
Lossless canvas-pixel PNG
The browser encodes the decoded canvas pixels as PNG without a PNG quality setting. Lossless does not promise original ICO-byte recovery or improved detail.
Decoded-alpha boundaries
PNG can carry decoded alpha, including semi-transparent edge pixels, but the converter does not invent alpha, crop the icon, remove backgrounds, or guarantee output size.
Good to know
Questions, answered.
Can Fileverses convert an ICO file directly to PNG?+−
Fileverses attempts to decode a direct ICO upload in your browser, then encodes the rendered result as PNG. Whether a particular ICO works depends on browser decoding and the file's contents. If decoding fails, export the intended icon representation as a browser-readable raster image with icon-capable software first.
Can I choose which ICO icon size or entry becomes PNG?+−
No. The route uses one image rendered by the browser and provides no ICO-entry selection, extraction, combination, or preservation. When a specific representation matters, choose it and export it in separate icon-capable software before converting.
Is ICO to PNG conversion lossless?+−
The browser's PNG encoding is lossless for the decoded canvas pixels it receives. That does not make the PNG a byte-for-byte copy of the ICO, recover another container entry, restore missing detail, or improve a small or soft icon.
What happens to transparent and semi-transparent icon edges?+−
PNG can carry decoded alpha values, including partially transparent boundary pixels, when they are present in the browser-rendered image. Fileverses does not create alpha, crop the icon, remove a background, or replace a background, so inspect the downloaded PNG for the result required by your destination.
Does this create vectors, editable artwork, or an app bundle?+−
No. Each successful conversion downloads one raster PNG from the browser canvas. It does not recover vector artwork, create editable paths or layers, process an application bundle, or repair image quality; keep the original ICO and editable source separately.
Are ICO files uploaded, and is the PNG size guaranteed?+−
Browser-readable files are processed locally and are not sent to a conversion server. You can queue up to 50 files under 50 MB each, and decoded images over 12 megapixels are rejected. PNG file size depends on the rendered pixels and browser encoder, so no particular size is guaranteed.
