What is an AVIF file?

AVIF (AV1 Image File Format) is a modern image format introduced in 2019 by the Alliance for Open Media. It uses the AV1 video codec to compress images at roughly half the file size of WebP and up to 70 percent smaller than JPEG, while maintaining equivalent or better visual quality. AVIF supports HDR, transparency, and animation.

Why can't I open AVIF files in Photoshop or Windows?

AVIF is a recent format and desktop software is still catching up. Photoshop versions before 23.2 cannot open AVIF. Windows Photo Viewer, Microsoft Office, and older versions of Figma also lack native AVIF support. Browsers are ahead — Chrome, Firefox, Safari 16.1+, and Edge all display AVIF natively.

Will converting AVIF to PNG lose quality?

No additional quality is lost. AVIF is usually lossy, so some detail was already discarded when the AVIF was originally created. But converting to PNG — a lossless format — stops any further degradation. The resulting PNG is pixel-for-pixel identical to the AVIF source and can be edited, re-saved, and archived without ever losing quality.

Can I convert PNG to AVIF instead?

Yes. If you want to convert PNG images to AVIF format (the reverse direction), our PNG to AVIF converter handles that. PNG to AVIF is useful when you want to reduce file size while maintaining modern browser compatibility. Both directions are free with no signup required.

What's the difference between AVIF and PNG?

AVIF uses lossy AV1-based compression for tiny file sizes and is ideal for web delivery. PNG uses lossless compression for larger but pixel-perfect files, and is universally supported across all software and platforms. AVIF is newer (2019), PNG is mature (1996).

Is AVIF better than WEBP?

AVIF offers better compression than WEBP — typically 20-30 percent smaller files at equivalent quality. However, WEBP has broader software support. For serving images on modern websites, AVIF is the better choice. Both formats support transparency and animation.

How do I convert AVIF to PNG?

Upload your AVIF file using the tool on this page. ConvertFileBox processes it server-side and provides a download link instantly. No signup, no software installation, no file limits. Your file is automatically deleted from our servers after 1 hour.

Can I convert AVIF to PDF?

Yes. If you need your AVIF image in PDF format (for document embedding, printing, or archival), our AVIF to PDF converter handles that. This is a less common conversion but useful for specific workflows involving printed documents or PDF-only platforms.

Is it safe to upload AVIF files?

Yes. Files uploaded to ConvertFileBox are processed on secure servers and permanently deleted within 1 hour of upload. We do not store, share, inspect, or sell your images. No account is required, so there is no email or personal data to leak.

Can I convert multiple AVIF files at once?

Yes. Batch conversion is fully supported — upload multiple AVIF files at once (200 MB limit per file) and download all converted PNGs together. There is no per-session limit.

Which is better for archiving: AVIF or PNG?

PNG. PNG is lossless and universally supported — you can open a PNG file 30 years from now on any system. AVIF is newer and may not be readable by future software without a compatible decoder. For long-term archival, PNG is the safer choice.

What does avif转png mean?

About AVIF to PNG conversion

AVIF (AV1 Image File Format) was introduced in 2019 by the Alliance for Open Media — a consortium that includes Google, Apple, Mozilla, Microsoft, and Netflix. It uses the AV1 video codec to compress still images, delivering up to 50 percent smaller file sizes than WebP and up to 70 percent smaller than JPEG while maintaining equivalent or better visual quality.

PNG (Portable Network Graphics) was created in 1996 as an open alternative to GIF. It uses lossless compression — every pixel is preserved exactly as it was encoded. PNG is universally supported across every browser, operating system, design application, and email client in existence.

Why Convert AVIF to PNG?

AVIF has a compatibility problem on the desktop. Browser support is broad (Chrome 85+, Firefox 93+, Safari 16.1+, Edge 121+), but desktop software is lagging. Adobe Photoshop versions before 23.2 cannot open AVIF. Older versions of Figma, most versions of Microsoft Office, Windows Photo Viewer, and many email clients reject AVIF outright. Converting to PNG solves every compatibility problem instantly.

AVIF vs WEBP vs PNG

AVIF beats WEBP on file size (about 20-30 percent smaller at equal quality). PNG beats both on compatibility and lossless preservation. AVIF is best for serving images on modern websites. WEBP is a middle ground for web delivery. PNG is best for editing, archiving, and universal sharing — every application opens PNG.

Related Conversions You Might Need

If you need to convert PNG to AVIF instead (going the other direction), our PNG to AVIF converter handles that. If you want to compare AVIF against WEBP, our AVIF to WEBP converter does that too. If you need AVIF as a PDF document, our AVIF to PDF converter is available for that specialized use case.

Quality Considerations

The conversion is fast and safe. AVIF is usually lossy (though it supports lossless encoding), so some detail was already discarded when the AVIF was created. Converting to PNG does not restore that lost detail, but it also introduces zero additional compression artifacts. The resulting PNG is a pixel-perfect representation of the AVIF source, and because PNG is lossless, further editing, archiving, and re-saving will not degrade the image.

Files are processed securely on our servers and automatically deleted after 1 hour. No signup required, no watermarks, no per-session limits.

AVIF uses lossy AV1-based compression to achieve file sizes 50-70% smaller than legacy formats — ideal for serving images on modern websites. PNG uses lossless compression to preserve every pixel exactly, producing larger files that are universally supported and safe to edit repeatedly. Converting AVIF to PNG does not restore detail lost during the original AVIF encoding, but it prevents any further degradation. For editing, archiving, or universal compatibility, PNG is the right choice. For raw file size on modern web delivery, keep the AVIF.
