What is HEIC?
HEIC is the format iPhones use for photos. It saves space on the phone but is awkward to share, since Windows and many apps cannot open it without converting first.
What is AVIF?
AVIF is a newer format built on the AV1 video codec. It produces noticeably smaller files than JPG or WebP at the same quality, with transparency and high dynamic range.
Questions
Is the HEIC to AVIF converter free?
Yes, it is free with no sign-up and no watermark. There is no cap on how many files you can convert, and nothing to install.
Do my files get uploaded to a server?
No. The conversion runs entirely in your browser using code that loads onto your device, so the file is read, converted, and downloaded locally. It never reaches us or anyone else.
Will the conversion lose quality?
AVIF uses lossy compression, so re-encoding can cost a little quality. Near the top of the quality setting the difference is hard to see, and for most uses it is not noticeable.
