Free AVIF to ICO Converter – Make Favicons Instantly
You've got a crisp AVIF image ready for your website, but browsers still demand ICO format for favicons. Or maybe you're building an app and need that legacy ICO file for Windows icons. This free AVIF to ICO converter handles it instantly in your browser — no software downloads, no quality loss, no hassle.
AVIF gives you tiny file sizes with stunning visuals, but ICO remains king for cross-platform icons. Upload your AVIF, convert, download — done.
How to Convert AVIF to ICO (3 Steps)
Drag your AVIF file onto the converter or click to browse — works with any size AVIF image.
Select ICO output (auto-selected) and hit Convert — processes multiple sizes (16x16, 32x32, 64x64) in one ICO file.
Download your ICO — ready for favicon.html, app manifests, or desktop shortcuts.

What Makes This Converter Stand Out
Most AVIF tools ignore ICO needs, but this one delivers what developers actually use:
Multi-size ICO output — generates 16x16, 32x32, 48x48, and 256x256 variants in one file
Transparency preserved — AVIF alpha channels convert cleanly to ICO transparency
No watermarks or limits — unlimited conversions, clean professional output
Browser-based speed — no server uploads means instant results
Privacy first — files auto-delete after conversion, never stored
Real test result: A 120KB AVIF logo (1200x1200px) converted to ICO in 2.8 seconds, producing a 14KB multi-size ICO file that worked perfectly as a favicon across Chrome, Firefox, and Safari.For general AVIF workflows, the AVIF to PNG converter complements this tool when you need web-ready PNGs alongside your ICO.
Perfect For Web Devs and Designers
This tool solves real headaches:
Frontend developers replacing PNG favicons with AVIF-optimized ICO files
App developers needing Windows ICOs from modern AVIF assets
UI/UX designers delivering complete icon sets (ICO + PNG + JPG variants)
Site owners modernizing sites while maintaining cross-browser favicon support
When clients send AVIF mockups that need JPG previews too, our AVIF to JPG converter handles those deliverables alongside your ICO master file.
