Frequently Asked Questions
What is AVIF format?
AVIF is a modern image format based on the AV1 video codec. It typically produces significantly smaller files than JPEG or WebP at the same visual quality.
Does my browser support AVIF encoding?
AVIF encoding support depends on your browser and system codecs. The tool automatically detects support and notifies you if AVIF is unavailable.
Does AVIF support transparency?
Yes. AVIF supports an alpha channel, so images with transparent backgrounds stay transparent after conversion.
Can I convert multiple files at once?
Yes. Select multiple images and they will be converted in batch. Download them individually or use Download All for a ZIP archive.
Is my image uploaded to a server?
No. All conversion happens entirely in your browser. Your images never leave your device.
What quality setting should I use for AVIF?
The Quality slider (default 80%) controls compression. For most images 70-85% offers an excellent balance of quality and file size.
