Does converting GIF to ICO improve the image quality?

No. GIF and ICO both store every pixel exactly, so the picture is untouched — only the file format changes.

What happens to transparency?

It survives. Both GIF and ICO carry an alpha channel, so transparent areas stay transparent.

Is there a file size limit?

No limit that we impose. The only ceiling is your device's memory, so a very large photo or a long recording may take a few seconds.

Are my files uploaded anywhere?

No. The conversion runs inside this browser tab, so the file never leaves your device — go offline once the page has loaded and keep converting.
