Quick access to the most commonly used image format conversions

This PNG to AVIF converter shrinks heavy PNG images into AVIF files for the web, and keeps transparent backgrounds. Large PNG illustrations, renders and cut-out product photos are where AVIF saves the most: files can drop to a small fraction of the original size.

It is free, with no sign-up and no watermark. AVIF is best for images you publish on a website. For broader app support, PNG to WebP also keeps transparency, and for photos without transparency you could use PNG to JPG. To turn AVIF back into PNG, use AVIF to PNG.

How to use PNG to AVIF Converter

  1. 1

    Add your PNG files

    Drop up to 10 PNGs, up to 20 MB each. Transparent images are fine.

  2. 2

    Keep AVIF selected

    AVIF is the preset output. The files are sent to our server, which encodes them as AVIF.

  3. 3

    Convert and download

    Press Convert, wait a few seconds per image while AVIF encodes, then download each file.

What you can make

Transparent product images

Cut-out product shots keep their transparent background at a much smaller size than PNG.

Lighter hero graphics

Large PNG illustrations and banners are often the heaviest files on a page. AVIF cuts them down.

Renders and artwork

3D renders, digital paintings and AI images saved as PNG compress very well as AVIF.

Web app assets

Convert PNG screens and illustrations used in onboarding, docs and marketing pages.

Screenshot-heavy docs

Help centres with many full-width PNG screenshots load faster with AVIF.

Bandwidth and CDN costs

Smaller images mean less data served per visit, which matters on high-traffic pages.

Why PNG to AVIF makes such a big difference

PNG is lossless. That is perfect for editing, but it makes photos, renders and detailed illustrations very large, often several megabytes each. AVIF is a modern format based on the AV1 video codec, and it compresses images far more efficiently, while also supporting an alpha channel for transparency.

The size gap between PNG and AVIF is much bigger than between JPG and AVIF, because you are going from lossless to efficient lossy compression. For photographic or painted PNGs, reductions of 80 to 95 percent are common. Transparent images keep their soft edges and shadows.

The converter encodes at quality 85 on the AVIF scale, which is a high setting aimed at results that look like the PNG at normal viewing size. Flat graphics with sharp edges, such as UI screenshots or diagrams, save less and may show slight softening around fine text if you zoom in. For those, compare the result with WebP or keep the PNG. Resizing oversized images first with Resize Image adds further savings.

Browser support and how the conversion runs

AVIF displays in current Chrome, Firefox, Safari (version 16 onwards) and Edge (since early 2024), so it is safe to use on most websites. For very old browsers, a picture element with a PNG or WebP fallback covers everyone. Outside the browser, support is still uneven: many image viewers, editors, office programs and email clients cannot open AVIF, so keep your PNG originals as editable masters.

Most browsers can display AVIF but cannot create it. For that reason this conversion runs on our server: each PNG is sent to RegiAI, encoded to AVIF, and the result comes straight back to your browser for download. Files can be up to 20 MB each. If you would rather keep everything on your device, PNG to WebP is created in the browser in Chrome, Edge and Firefox and still gives large savings.

When to keep PNG instead of AVIF

AVIF is excellent for images on web pages, but a PNG is still the better file in several cases:

  • App icons, favicons and store assets. App stores, browser manifests and many platforms require PNG for icons.
  • Screenshots with small text. Lossy AVIF can soften very fine text slightly. Compare the result at 100 percent, and try PNG to WebP if it matters.
  • Pixel art and sprites, where every pixel must stay exact.
  • Files for email, print or clients who may open them in software without AVIF support.
  • Master files you will edit again.

A good rule is PNG for sources and AVIF for what your visitors download. Cutting out a product photo first? Use the Background Remover, then convert its PNG output here for a small transparent AVIF.

Frequently Asked Questions

Still stuck? Contact us.

How do I convert PNG to AVIF?

Add up to 10 PNG files, keep AVIF as the output and press Convert. Download each AVIF when it is finished.

Does PNG to AVIF keep transparency?

Yes. AVIF supports an alpha channel, and transparent areas stay transparent.

Is this PNG to AVIF converter free?

Yes. No account, no watermark and no charge.

How much smaller is AVIF than PNG?

For photos, renders and detailed artwork, often 80 to 95 percent smaller. Simple flat graphics save less.

Is the AVIF lossless?

No. It is lossy AVIF at a high quality setting (85). It looks like the original at normal size but is not a pixel-exact copy, so keep your PNG masters.

Are my PNG files uploaded?

Yes, for this conversion. Browsers generally cannot encode AVIF, so each file is sent to our server, converted and returned to you for download.

What is the maximum file size?

Up to 20 MB per PNG, and up to 10 files per batch.

Why does AVIF encoding take longer?

AVIF compression is computationally heavy. It takes longer than PNG, JPG or WebP, usually a few seconds per image.

AVIF or WebP for transparent images?

AVIF is usually smaller; WebP is supported by more apps and encodes faster. Both keep transparency and both work in all current browsers.

Can I use AVIF on WordPress?

Recent WordPress versions accept AVIF uploads, provided your server's image library supports AVIF. If uploads fail, use WebP.

Can I convert AVIF back to PNG?

Yes, with AVIF to PNG. The transparency returns, but the small loss from AVIF compression stays.

Are the dimensions changed?

No. The AVIF has the same width and height as your PNG.

Can I convert AI-generated PNG images to AVIF?

Yes. Images from generators, including RegiAI's AI Image Generator, often arrive as large PNGs and compress especially well as AVIF.

Does AVIF support HDR?

The format does, but a standard PNG has no HDR data to carry over, so the AVIF made here is standard dynamic range.

Can I convert several PNGs to AVIF at once?

Yes, up to 10 per batch. Each is encoded in turn and downloads separately.
