About JPG to AVIF
JPG to AVIF creates AVIF versions of your photos. AVIF is among the most efficient image formats, often producing files far smaller than JPG at the same visual quality, which helps websites load faster and saves bandwidth and storage. It is supported by current Chrome, Edge, Firefox and Safari.
Choose the quality, add one or many JPG files and download the results, bundled in a ZIP when there are several. AVIF encoding is demanding, so large pictures take longer than other conversions. Browsers cannot normally write AVIF on their own, so a small encoder program may be downloaded the first time you convert; your pictures are still processed on your device and never uploaded.
No watermark is added and no account is needed. If you want wider compatibility, JPG to WebP is supported everywhere. To make files smaller without changing the format, use Compress Image, and to convert back use AVIF to JPG.
Frequently asked questions
Is AVIF smaller than WebP?
Often yes, especially for photos, although encoding takes longer. WebP has slightly wider support in older software.
Why is the conversion slow?
AVIF is a demanding format to create. Large photos can take several seconds each. Converting a few at a time is best.
Do I need an account to download?
No. You can use JPG to AVIF and download your result instantly without signing up, and without giving an email address. A free PDFZOID account is optional.
Are my files uploaded to a server?
No. JPG to AVIF works inside your browser, so your pictures stay on your device and are never sent to PDFZOID.
Is there a watermark?
No. PDFZOID does not add a watermark or any branding to your result.
