How to convert PNG to AVIF

Choose a PNG, customize the AVIF output, and download it when your browser supports AVIF encoding.

Select an image from your device or drag it into the upload area.

Choose quality, dimensions, and an optional maximum file size.

Review the preview and file size, then save the converted image.

This free online PNG to AVIF converter includes the following controls and output tools:

Private browser conversion. The image is processed locally and is not uploaded.
Custom dimensions. Set an exact width and height, lock the aspect ratio, and prevent accidental enlargement.
Quality and file-size controls. Set AVIF quality or enter a maximum size in KB to find the highest quality that fits.
Before-and-after preview. Review the original and converted image, output dimensions, format, and file size.
File-size comparison. See the original and converted sizes and the percentage change.
Custom filename. Rename the converted file before downloading it.
Metadata-free export. The newly encoded AVIF does not copy source metadata.

Complex or photographic PNG images can become substantially smaller as AVIF, helping reduce transfer size on modern websites.

Lossy AVIF quality settings may soften sharp text, logos, or interface graphics. Inspect the preview and keep the original PNG.

Transparent PNG pixels remain transparent when the browser AVIF encoder supports alpha output.

AVIF encoding availability varies by browser. Source PNG metadata is not copied into the newly encoded file.

Is this PNG to AVIF converter free?

Yes. Convert one PNG image at a time without an account.

Will transparency remain?

Supported AVIF encoders retain transparent pixels.

Why can export fail?

Some browsers can display AVIF but cannot encode it.

Will AVIF always be smaller?

Not always, especially for small or simple graphics already efficiently encoded.

Does my PNG get uploaded?

No. Conversion happens locally in your browser.
