❓ About AVIF Conversion (FAQ)

This tool converts images to AVIF format inside your browser. Your files are never uploaded to a server; processing happens on your device. AVIF encoding support varies by browser; unsupported browsers will see a warning.

Where does the AVIF conversion happen?

Conversion happens inside this page, in your browser. Files are never sent to a server. This protects privacy; speed depends on your device and the image size.

Which browsers support AVIF encoding?

Recent versions of Chrome and Edge generally support AVIF encoding. Firefox and Safari support may be limited or unavailable — in that case the tool clearly warns you and does not convert.

Is transparency preserved?

Yes, AVIF supports transparency (alpha). If the source image has transparency, it is preserved in most scenarios. JPG sources have no transparency to begin with, so nothing changes there.

Why isn't the AVIF output as small as I expected?

File size depends on quality level, resolution, and image detail. A very high quality setting can increase file size. Some images may also already be well optimized.

How does bulk download (ZIP) work?

Successfully converted AVIF files accumulate in browser memory and are downloaded as one ZIP. Files that fail or can't be encoded by the browser are not included.

When should I choose AVIF?

AVIF is a great choice for speed, SEO, and performance-focused images on websites; it usually produces smaller files than JPG/WebP. Keep a JPG/WebP fallback where maximum compatibility is required.

Tip: AVIF is great for web performance but may not open in every browser/app; keep a WebP/JPG fallback for critical use cases.
