Good to know
  • AVIF output appears only in browsers that can encode AVIF. WebP output is unavailable in a few older Safari versions.
  • Converted files contain no EXIF metadata, so location and camera details are removed. Rotation is applied to the pixels.
  • GIF input uses the first frame only. Multi-image HEIC files (bursts) use the first image.
  • Very large batches are converted one file at a time to keep memory use low.

When to convert AVIF to PNG

PNG is the right target when an AVIF image has transparent areas, when you want to edit it further without adding another round of lossy compression, or when a design tool accepts PNG but not AVIF.

Because PNG is lossless, the result is the AVIF exactly as your browser decoded it. Any detail AVIF compression already removed stays removed, but nothing further is lost.

How to convert AVIF to PNG

  1. Add AVIF files. Drop them on the bay or choose them.
  2. Keep PNG selected. PNG is lossless, so there is no quality slider.
  3. Limit dimensions if needed. Large AVIF photos make very large PNGs; a max width keeps them manageable.
  4. Download. Individually or as a ZIP.

Settings explained

Max width and height
Scales down proportionally. The best way to control PNG file size.
Max size per image (KB)
Reduces dimensions until the PNG fits the limit.

Why sites serve AVIF

Image CDNs often send AVIF to browsers that support it because the files are small, even when the address ends in .png or .jpg. When you save such an image you get AVIF data, sometimes with the wrong extension. Myriadfile detects the real format from the file’s content, so these files convert normally.

If you only need to view or share the image, AVIF to JPG gives a much smaller file. Choose PNG when you will edit the image or need its transparent background.

File size expectations

AVIF is one of the most efficient image formats available, and PNG is one of the least efficient for photos. A 200 KB AVIF photo can easily become a 5 MB PNG. For graphics with flat colours the difference is far smaller.

Transparency and edges

PNG stores full alpha transparency, so soft shadows and anti-aliased edges in AVIF cut-outs are preserved.

Troubleshooting

The AVIF will not load
Your browser needs AVIF support. Update it, or try Chrome, Edge, Firefox or Safari.
The PNG is enormous
Use JPG or WebP for photos, or set a max width.

Frequently asked questions

Is the conversion lossless?

Yes from this point on: PNG keeps the decoded image exactly.

Does it keep HDR?

No. PNG output here is standard dynamic range, 8 bits per channel.

Are images uploaded?

No. Everything happens in your browser.

Can I batch convert?

Yes, add as many files as you like.

Which is smaller, PNG or JPG?

For photos, JPG by a wide margin. For simple graphics, PNG is often competitive.
