Frequently Asked Questions
What is AVIF?
AVIF is a modern image format based on AV1 compression. It is designed to deliver high-quality images with smaller file sizes for the web.
Is AVIF smaller than WebP?
Often, yes, but not always. Results depend on the image and quality setting, so compare the output before replacing production assets.
Are my images sent to ConvertUnlimited servers?
No server-side upload endpoint is used for this AVIF conversion flow. The browser decodes and encodes images locally when AVIF encoding is supported.
Why does AVIF conversion not work in some browsers?
Some browsers can display AVIF but cannot export AVIF through Canvas yet. In that case the page shows a friendly unsupported-browser message.
Can I convert multiple images at once?
Yes. Add multiple files, convert them together, then download each AVIF file or a ZIP archive.
