Add an ICO your browser can decode
Drop, paste, or choose the ICO. If this browser cannot read that container, export the icon representation you need as PNG or another browser-readable raster image before converting it.
Free online ICO to GIF converter
Fileverses can convert an ICO only when the current browser decodes it into an image. It draws that one browser-rendered icon to a local canvas, then writes a static GIF89a with a reduced palette and binary transparency. No conversion server receives the file.

About this converter
ICO is an icon container that can hold several embedded images and sizes, while GIF is a raster format. Fileverses treats an ICO as usable only when the current browser can decode it into an image. The browser supplies one rendered icon image to the canvas; this page does not inspect the ICO container, select an embedded entry or size, or extract a representation for you. For a decoded icon, the GIF encoder writes one static GIF89a frame with up to 255 opaque palette colors and one binary transparent entry. Palette reduction can alter subtle colors or gradients, and smooth alpha cannot survive: pixels with alpha below 16 become transparent and all other pixels become opaque. This is not an animation workflow, application-bundle workflow, or vector-art recovery tool. It cannot recover missing detail, crop artwork, remove a background, create transparency, or guarantee a particular output size. Keep the original ICO and inspect the downloaded GIF in the destination that requires it.
How it works
Drop, paste, or choose the ICO. If this browser cannot read that container, export the icon representation you need as PNG or another browser-readable raster image before converting it.
Fileverses draws the single browser-rendered icon image to a local canvas and encodes one static GIF89a frame. It cannot choose among ICO entries, so review the rendered image first.
Check dimensions, palette colors, binary transparent edges, compatibility, and file size in the destination that requested GIF. Keep the ICO when you may need another embedded icon representation.
Made for real pipelines
Convert without uploading your assets. Switch outputs anytime — web, print, icons, and document targets from the same batch.
Convert a browser-decoded ICO to a static GIFConvert an ICO only when the current browser can decode it, using the single rendered icon image it supplies rather than a selected container entry.
Create one local GIF89a frame with up to 255 opaque palette colors and one binary transparent entry; this is not an animation export.
Work within the 50-file, 50-MB-per-file, and 12-megapixel limits, then inspect colors, hard transparent edges, dimensions, compatibility, and final size in the receiving workflow.
Good to know
No. Fileverses can proceed only when the current browser decodes the ICO into an image. If decoding fails, export the icon representation you need as PNG or another browser-readable raster image first, then create GIF from that image here.
The browser supplies one rendered ICO image to the conversion canvas. Fileverses does not inspect the ICO container, list its embedded entries, or let you choose a particular icon size. Verify the rendered result and keep the original ICO if you need a specific entry later.
No. For a browser-decoded ICO, this encoder writes one static GIF89a frame. It does not preserve or create animation, timing, multiple frames, or a moving GIF.
The GIF encoder uses up to 255 opaque palette colors plus one transparent entry. Gradients and subtle colors can band or shift. Transparency is binary: pixels with alpha below 16 become transparent and all other pixels become opaque, so smooth alpha edges are not retained.
No. Fileverses encodes the one browser-decoded raster image without recovering lost detail, rebuilding vector artwork, cropping artwork, or removing a background. It also does not create transparency from an opaque icon.
You can queue up to 50 supported files under 50 MB each, and a decoded image over 12 megapixels is rejected. The GIF is made locally in your browser without sending a supported ICO to a conversion server. A smaller file is not guaranteed; size depends on rendered dimensions, palette, and image complexity.
