FAQ
Are my files uploaded?
No. Conversion runs entirely inside your browser; your images never reach any server, so even sensitive files stay private.
Is it free?
Completely free. No account, no installation.
Can I convert multiple files at once?
Yes — drop several HEIC files at once and download them all as a ZIP.
Will quality be lost?
AVIF is a lossy format; use the quality slider to balance quality and file size.
