What PNG to AVIF conversion does

Convert a PNG into AVIF for modern web delivery with adjustable quality. Encoding uses the browser canvas API and is verified as a real image/avif download.

Smaller files are not guaranteed. Encoding support is Chromium-first today.

How to convert PNG to AVIF

1. Choose a .png file.
2. Adjust AVIF quality if needed.
3. Select Convert & download.
4. Save the .avif file from your downloads.

Why convert PNG to AVIF

AVIF can shrink UI graphics and photos for sites that already serve modern image formats.

AVIF quality control

The quality slider defaults to 90%. Lower values usually shrink the file and can introduce compression artifacts.

Transparency handling

Transparent PNG pixels stay transparent when the browser AVIF encoder supports alpha. This tool does not flatten onto an arbitrary background before encoding.

AVIF encoding compatibility

The tool probes canvas AVIF encoding and checks the blob MIME type. If the browser falls back to PNG or another format, you get a clear error—no mislabeled download and no usage count.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted images remain on your device.

Limits

• Inputs: PNG only, up to 25.0 MB and 8,192 px per side.
• Canvas AVIF encoding must succeed with a verified image/avif blob. Support is Chromium-first.
• Conversion is lossy via the quality slider. Alpha retention depends on the browser encoder.
• Metadata is not preserved.

PNG to AVIF FAQ

Does AVIF preserve PNG transparency?

When the browser’s AVIF encoder supports alpha, transparent PNG pixels stay transparent. This tool does not flatten onto an arbitrary background. It does not claim lossless or pixel-perfect output.

Can every browser create AVIF?

No. Canvas AVIF encoding is Chromium-first today. The tool probes encoding support and verifies the download is image/avif. Unsupported browsers get a clear error instead of a mislabeled file.

Will AVIF always be smaller?

Often for web delivery, but not always. Results depend on the image and AVIF quality. This tool does not promise a smaller file.

Can I adjust AVIF quality?

Yes. Use the AVIF quality slider (50%–100%, default 90%).

Are images uploaded?

No. PNG to AVIF runs locally in your browser and does not upload your image to Looty Tools servers.

Is conversion lossless?

No. Canvas AVIF encoding with a quality slider is lossy. Lower quality usually shrinks the file and can introduce artifacts.
