Transparency stays transparent
AVIF can carry an alpha channel and so can PNG. In our test the transparent circle in the middle of the picture was still fully transparent in the PNG, so a cut-out or logo keeps its see-through background.
AVIF to PNG Converter
Add an AVIF file and get a lossless PNG back. A still AVIF with transparency keeps its transparent areas. An animated AVIF is not converted.
To convert avif to png, add the .avif file, keep PNG as the output format and download the result. In our test, an 11,686 byte 10-bit AVIF with transparency became a 20,639 byte png that kept its transparent pixels, so expect a larger file.
Transfers use HTTPS, and files converted on the free tier are deleted after 24 hours, so the result is not a long-term archive. Quality depends on the source file, so open the PNG file once before you share it.
FromAVIFLossyTransparency
AVIF (AV1 Image File Format)
A modern image format from the Alliance for Open Media that stores pictures using AV1 video compression. It compresses far harder than JPG and supports transparency, HDR, 10 and 12-bit colour and animation, but reached browsers only around 2020.
ToPNGLosslessTransparency
PNG (Portable Network Graphics)
A lossless raster format with a full alpha channel. It preserves every pixel it is given and supports transparency, which makes it the usual choice for logos, screenshots, and any image with sharp edges or text.

Why use indox to convert AVIF to PNG?
Opens where AVIF does not
Some editors and viewers still cannot open .avif files. PNG opens in practically every app, browser and upload form, so one conversion makes the picture usable again.
No software on your computer
The conversion runs on indox servers, so it works from Windows, Mac, Linux, Android or iPhone with only a browser. In our test we used it anonymously, with no sign-in.
Animated files are not converted
An animated AVIF is not turned into a still. In our test a three-frame animated AVIF failed and no PNG was offered; the limits below say what to do instead.
What happens to your AVIF
Stays
- Your original AVIF, which is not touched
- The pixel size, 1200 × 800 in our test
- Transparent areas, fully transparent in our test
- 10-bit depth, delivered as a 16-bit PNG
Changes
- File size: 11,686 bytes became 20,639 bytes in our test, 1.77 times larger
- Compression: lossless PNG replaces lossy AVIF storage
- Animation: an animated AVIF fails and gives no PNG
- File name: the download starts with a hash and ends in _converted.png
How do I convert AVIF to PNG online?
- 1
Add your AVIF file
Drop the .avif file on the converter or choose it from your device. Keep the original, because the PNG is a decoded copy and cannot be turned back into the smaller AVIF.
- 2
Confirm PNG, then start the conversion
Check that PNG is the output format and start the conversion. In our test it took 3.2 seconds from the click to Completed, including the upload.
- 3
Download the PNG and check the edges
Save the PNG and open it on a checkerboard or dark background to confirm the transparent areas. The saved file name starts with a short hash, followed by your original name and _converted.png.
What do I get from indox's AVIF to PNG converter?
You add a still AVIF and take away a lossless PNG that keeps transparency and colour depth and opens in the software that refuses AVIF. The page states the size growth and the animated-file failure that we measured, so you know before you convert whether it fits the job.
- One PNG for the AVIF you add, kept at the full pixel size
- Transparency and 10-bit depth carried over in our test
- Nothing to install on Windows, Mac, Linux or a phone
- Size growth and the animated-AVIF failure stated up front
What are the limits for AVIF to PNG?
Size
The upload box shows the live size limit before you add a file. Signing in raises it; a paid plan does not change it.
Formats
AVIF in, PNG out. Pick another output on the converter if you need a different format.
Privacy
Files are encrypted in transit over HTTPS and processed on indox infrastructure.
Deletion
Free-tier files are kept for 24 hours after the job finishes, then deleted automatically.
Limits worth knowing
- Animated AVIF is not supported. In our test a three-frame animated AVIF ended as Failed after about 1.5 seconds and no PNG was offered. A local libheif tool refused the same file too. Pull out one frame with an AVIF-aware tool first, or convert a still version.
- The PNG is normally larger than the AVIF, sometimes much larger on photos. If size matters more than lossless pixels, convert to JPG or WebP instead.
- There is no quality setting. PNG is lossless, so the converter has nothing to trade, and you cannot ask for a smaller PNG.
- We did not test HDR. Our 10-bit sample used standard dynamic range colour. We cannot say how an AVIF with PQ or HLG HDR is handled, so check the result on a calibrated screen if colour accuracy matters.
- The saved file name carries a hash prefix, so rename it if a form or a project expects the original name.
When the result is not what you expected
| What you see | Why | What to do |
|---|---|---|
| Status Failed and no PNG | The file may be an animated AVIF, which this converter did not convert in our test | Extract one frame with an AVIF-aware tool, then convert that still |
| The PNG is much bigger | PNG is lossless and AVIF was heavily compressed | Use AVIF to JPG when size matters and transparency does not |
| A white or black box around the picture | Your viewer is not showing the alpha channel | Open the PNG on a checkerboard background or in an editor with layers |
| Colours look washed out | The viewer may not handle the colour information | Compare in a second viewer before blaming the file |
| A site still rejects the file | Renaming a file does not change its contents | Upload the converted .png, not a renamed .avif |

Which conversions are close to AVIF to PNG?
AVIF vs PNG: what is the difference?
| Compared on | AVIF | PNG |
|---|---|---|
| Compression | Lossy or lossless, usually lossy and very compact | Lossless, every pixel stored |
| Transparency | Yes, as an alpha channel | Yes, as an alpha channel |
| Colour depth | 8, 10 or 12 bits per channel | 8 or 16 bits per channel |
| Animation | Image sequences are possible | Not in a plain PNG; APNG is a separate extension |
| Where it opens | Modern browsers, newer apps | Practically every app, browser and form |
| Typical use | Small web images | Logos, screenshots, editing copies |
Who can use a AVIF to PNG converter?
When to use it
- Opening a downloaded AVIF in Photoshop or a photo viewer that does not read it.
- Uploading an AVIF graphic to a site that accepts PNG and JPG only.
- Keeping a transparent logo or sticker that arrived as AVIF.
- Making a lossless copy of an AVIF for editing, without another lossy re-save.

AVIF to PNG FAQs
How do I convert AVIF to PNG for free?
Open the converter, add your .avif file, keep PNG as the output and download the result. In our test we did this anonymously, with no sign-in and no limit message.
Does the PNG keep transparency?
Yes, in our test. The transparent circle in a still AVIF was fully transparent in the PNG. Open the result on a checkerboard to check the edges.
Why is my PNG bigger than the AVIF?
AVIF compresses lossy and very tightly, while PNG stores every decoded pixel without loss. Our 11,686 byte AVIF became a 20,639 byte PNG, 1.77 times larger. Photos can grow more than flat graphics.
What happens to an animated AVIF?
It fails. In our test an animated AVIF with three frames showed Failed and gave no PNG. Use a tool that can extract a single frame first, or start from a still image.
Does converting lose quality?
The PNG does not lose anything further from the decoded picture, but it cannot restore detail that AVIF compression already removed. For editing, it is a safe lossless copy.
Will 10-bit colour survive?
In our test, yes. A 10-bit AVIF gave a 16-bit PNG with 760 distinct red levels in one gradient row. We did not test HDR files that use PQ or HLG.
Why PNG instead of JPG?
Choose PNG when you need transparency or exact pixels. Choose JPG when a smaller file matters more and the picture has no see-through areas.
Can I open AVIF in Windows Photos or Photoshop?
Support depends on your version and installed extensions, and some setups still cannot open AVIF. Converting to PNG avoids the question.
Is the file really an AVIF?
A renamed file can fail. If the converter reports Failed on a still image, check that it is a true .avif file and not a JPG or WebP with a changed extension.
Is the conversion private?
The page says free-tier files are deleted after 24 hours. Do not upload anything you are not allowed to share with a service.
