✦ AVIF IMAGES · PROCESSED LOCALLY

Convert AVIF to PNG
privately in your browser.

Convert AVIF images into losslessly compressed PNG files directly in your browser. PNG is more broadly compatible and works with programs that do not accept AVIF. Your files remain on your device.

FORMAT KNOWLEDGE

What happens when AVIF becomes PNG?

LokalPix decodes the AVIF using browser functions and stores the visible image losslessly as PNG.

AVIF

AV1-based image format

AVIF uses the AV1 codec for still images and supports transparency through an alpha channel as well as HDR colour spaces.

PNG

Lossless output with transparency

PNG stores all visible pixel values losslessly. If the AVIF contains transparency, it is carried over to the PNG.

IMPORTANT

No quality recovery

PNG cannot reconstruct detail removed by AV1 compression. Conversion only changes the file format of the existing pixels.

FORMAT IN DEPTH

AVIF and PNG compared

Technical background for choosing the right format.

How AVIF encodes

AVIF uses AV1 techniques such as intra-frame prediction and quantisation for still images. It supports wide colour spaces and high bit depth. Browsers decode AVIF natively via createImageBitmap.

How PNG encodes

PNG uses lossless DEFLATE compression. It supports transparency through an alpha channel and is compatible almost everywhere.

Why PNG is useful

PNG is more broadly compatible than AVIF and is accepted by most image editors and upload forms.

What is lost?

Earlier AV1 losses remain. HDR information and AVIF-specific metadata are not transferred by default.

FREQUENT QUESTIONS

Questions about AVIF to PNG

Answers about quality, privacy, and format limitations.

Is transparency carried over to PNG?

Yes. If the AVIF has an alpha channel, it is transferred to the PNG. Check the result for cut-out subjects.

Why is the PNG file larger?

PNG is lossless and is usually larger than AVIF for photographs. Larger does not automatically mean better quality.

Does PNG improve AVIF quality?

No. PNG stores the decoded pixels losslessly but cannot undo AV1 losses.

Are resolution and aspect ratio preserved?

Yes. LokalPix does not intentionally change the pixel dimensions during this conversion.

Are metadata preserved?

Metadata are removed by default. AVIF-specific EXIF data are not transferred to the PNG file.

Can I convert several AVIF files?

Yes. Up to 20 files can be processed in one batch and downloaded individually or together as a ZIP archive.
