PNG to AVIF Converter

Why create an AVIF version from PNG

PNG is often used as the source for transparent web graphics: logos, cut-out product images, interface elements, icons, and illustrations with sharp edges. If your site or app can accept AVIF, you can prepare an additional version of such an image and check whether it works for publication.

This does not mean the original PNG is no longer needed. PNG is convenient as a working file for editing and passing into systems with well-defined requirements, while AVIF is a candidate for a specific web output. The decision is made after comparing the visual result, file size, and support in the system you are using.

Transparency and graphics quality

If a PNG contains a transparent object, check the background, smooth edges, and shadows in the resulting AVIF. A cut-out product on a white card may look fine, but on a dark background it may show an unwanted halo. Logos and small icons need to be reviewed at the sizes the visitor actually sees them.

For screenshots, diagrams, and images with text, readability is especially important. Do not accept degraded lines or letters just because the new file is convenient for a web scenario. When graphics accuracy is critical, keep PNG in the publication or compare another format.

Where an AVIF version may be useful

Product image without a background

A content manager stores the master product file as PNG and tests a version for the catalog. Create an AVIF, place it in a test product card, and check the object edges, text on the packaging, and display time in the accepted workflow. Keep the PNG as the source for the next variants.

Decorative page graphics

An illustration, banner, or background with transparent parts may be used in an interface or promotional block. AVIF should be compared on mobile and desktop layouts, as scale and background can reveal differences that are not visible in a standalone viewer.

Icon or logo

For small elements, edge quality matters more than any assumed benefit of a different file format. If the team has a vector original, use that as the primary source. An AVIF made from PNG works as a testable version for a specific location on the site, not as a replacement for original brand materials.

How to decide whether to publish

1. Select a few files of different types: a product image, an icon, an illustration, and graphics with text.
2. Convert them and compare with the PNG on real backgrounds and page sizes.
3. Check whether your CMS, template, or external publishing channel accepts AVIF.
4. Compare file size only after confirming visual quality.
5. Keep PNG for edits and for preparing an alternative format.

When another format is needed

If the web system does not accept AVIF or you need another compatible option for transparent graphics, compare PNG to WebP. When you need to return an AVIF copy to a working format, use AVIF to PNG. For a photo without transparency that needs to be sent or uploaded in a standard way, PNG to JPG may be appropriate.

A file with animation or unusual display behavior requires separate testing: a static conversion may not match the original purpose. Do not delete the PNG until the final version has been tested with real users or in the published interface.

For a team it is useful to track the link between files: PNG remains the approved source, and AVIF receives an assignment for a specific page or component. If the background, image size, or card layout changes later, prepare a new version from the PNG rather than re-encoding the already published variant. This reduces the risk of accumulating visible defects.
