GIF loops to ICO: a real favicon.ico, nothing uploaded
Processed in your browser. Nothing is uploaded. Updated on 24 Oct 2026.The work here is mechanical: your GIF is unpacked into raw pixels and repacked as ICO. Everything else in the old file is dropped, and in exchange you get the sizes Windows and older browsers look for, in a single file. ICO holds one frame, so only the first frame is kept. Icons are saved at small sizes, not at the original size. The whole conversion happens inside this browser tab, so the picture never leaves your device.
Choose the GIF; ICO is already set under Convert to.
The icon is made from the first frame, centred on a square so it is not stretched.
The .ico holds 16, 32 and 48 px icons, plus 64, 128 and 256 px when the GIF is that large.
Press Convert to ICO, then Download and use the file as favicon.ico or a shortcut icon.
Convert Image reads ten formats and writes seven. It opens JPEG, PNG, GIF, WebP, AVIF, BMP, TIFF, ICO, SVG and HEIC, and saves as JPEG, PNG, WebP, AVIF, BMP, TIFF or ICO. Drop up to twenty files in and each row shows the new size beside the old one as it finishes.
What a conversion costs is stated before it runs, not after the download. JPEG has no transparency, so transparent areas are filled with a colour you pick, white by default. BMP is the same. A multi-page TIFF gives you one file per page by default; an animated GIF or WebP keeps its first frame by default, with every frame available on browsers that can read them. An ICO is written as a genuine icon file holding 16, 32, 48, 64, 128 and 256 pixel versions, each stored as a PNG.
Two jobs are refused on purpose. GIF is not written, because a good GIF needs a hand-chosen 256-colour palette and a bad one looks worse than the original. Camera RAW and Photoshop PSD files are not opened, because both need decoders far too large for a browser; export a JPEG or TIFF from your camera software, or a PNG from Photoshop, and bring that here. Nothing becomes an SVG: tracing pixels into shapes is a different job with different results.
The rest of the article, and all 8 questions about Convert Image, are on the Convert Image page.
Reading works for JPEG, PNG, GIF, WebP, AVIF, BMP, TIFF, ICO, SVG and HEIC; writing works for JPEG, PNG, WebP, AVIF, BMP, TIFF and ICO. That is every pair those two lists allow, about sixty of them, and each pair has its own page with the target format already chosen for you.
Frames are counted the moment the file is dropped, and the first one is kept by default, because a still is what people usually want. Chrome and Edge can read every frame, and there the choice 'All 12 frames' gives you one file per frame. Other browsers can only read the first, and the page says so rather than pretending.
Writing AVIF and WebP is done by the browser, and not every browser can. Chrome and Edge write both; Firefox and Safari often cannot write AVIF. A format this browser cannot write is disabled with a note naming the browsers that can, so nothing is silently saved in the wrong format.
Twenty files per batch and 50 MB per file. Nothing is uploaded: the conversion runs in your browser, the TIFF and HEIC readers load only when one of those files arrives, and the converted files are built on your own device.
