Questions about PNG to ICO
- Does converting PNG to ICO improve the image quality?
- No. PNG and ICO both store every pixel exactly, so the picture is untouched — only the file format changes.
- What happens to transparency?
- It survives. Both PNG 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.
