Frequently asked questions
How do I convert AVIF to WebP?
Open this page, drop your AVIF file(s) into the box, optionally adjust quality, then click Convert and download the resulting WebP file. Everything happens locally in your browser.
Is it really free?
Yes. FormatBox is completely free with no sign-up and no watermark. There is no hidden cost and no file limit.
Are my files uploaded to a server?
No. Your images are processed entirely in your browser using your device's own capabilities. The files never leave your computer or phone.
Will I lose image quality?
It depends on the format. WebP uses lossy or lossless compression depending on the target. You can adjust the quality slider; higher quality means a larger file.
What is AVIF?
AVIF is a modern image format based on the AV1 video codec. It offers much better compression than JPEG or PNG at the same quality, which is why it is increasingly used on the web and by newer phones and cameras.
Can I convert multiple files at once?
Yes. You can drop several AVIF files at once and they will be converted one by one, each available for download.
