What to expect from HEIC to AVIF
What changes in the file, and what to check before you share the result.
Works where HEIC does not
HEIC is the default photo format on recent iPhones, but many websites, upload forms, and Windows apps still reject it. AVIF removes that obstacle while keeping the photo's dimensions.
Resize in the same step
Open the converter settings to set an output width and quality for every AVIF in the batch. Leave the width empty to keep the original dimensions.
HEIC to AVIF questions
Short answers about limits, privacy, and keeping the converted file.
Why do some sites reject my HEIC photos?
HEIC support is uneven outside Apple devices. Many browsers, upload forms, and older programs only accept formats such as JPG and PNG, so converting to AVIF lets you upload the photo anywhere that accepts AVIF.
Is the HEIC to AVIF converter free?
Yes. Without an account you can convert up to 10 files a day, 2 at a time, up to 25 MB each. A free account adds monthly conversion credits and larger files.
How long are my files kept?
Guest uploads and results are deleted automatically after 1 hour. Conversions stay temporary when you are signed in too, unless you save a result to your workspace.
Can I get a permanent link to the AVIF file?
Yes. Save the result to a SteadyLink workspace and it gets a stable link. If you make a new version later, replace the file and the link stays the same.
