AVIF to PNG converter

AVIF → PNG kept the transparent corners of our alpha AVIF and expanded the 1,689 byte source to a 3,575 byte PNG.

What you get — and what changes

Element	Result	What happens
Alpha channel	Kept	The transparent AVIF corner decoded to RGBA PNG with a zero alpha value in the sampled pixel.
Visible AVIF artifacts	Kept	PNG stores the decoded AVIF result losslessly, including compression artifacts already present in the source.
ICC profile	Kept	The AVIF-to-PNG output exposed an icc_profile key when opened with our image engine.
Text metadata	Lost	Text chunks from the original PNG used to create the AVIF were still absent after AVIF → PNG.
File size	Changed	The 96×64 transparent AVIF grew from 1,689 bytes to 3,575 bytes as a lossless PNG.
Bit depth	Changed	The output opened as 8-bit RGBA PNG, so this is not a high-bit-depth preservation route.

Sample conversions

AVIF logo returned to an editor

Input: A 96×64 AVIF with transparent corners, created from PNG artwork and saved at quality 90.
Output: A 3,575 byte RGBA PNG. The empty corner was transparent, and the output had an ICC profile key.

AVIF photo for annotation

Input: A compressed AVIF photo that needed arrows and labels in a tool that accepts PNG but not AVIF.
Output: A PNG suitable for editing. The decoded AVIF look stayed the same; the conversion did not restore pre-AVIF detail.

A real AVIF → PNG run

We converted our AVIF sample (15 KB) with Image engine on 2026-10-20. It took 265 ms and produced a 67 KB PNG file, 4.4× larger than the input. The engine raised 1 warning, listed below.

Input · sample.avif · 15 KB

1200 × 800 px, avif

Width: 1,200
Height: 800
Encoding: avif

Output · sample.png · 67 KB

1200 × 800 px, 8-bit, colour type 6

Width: 1,200
Height: 800
Encoding: 8-bit, colour type 6

Image metadata stripped from output.

Is your file a scan?

AVIF → PNG can make a screenshot easier to inspect in older tools, but it still contains pixels. Use OCR routes before or after conversion when text extraction is the real task.

Options and when to change them

width: Resize while converting if the PNG editor or upload target rejects the AVIF's full pixel dimensions.
height: Set alongside width when producing an exact PNG canvas size.
fit: Use contain to pad within a canvas, cover to crop, or fill to stretch to the requested dimensions.
background: Use only with contain resizing when padded transparent margins need a deliberate color.

Do it yourself

ImageMagick 7 with AVIF support

bash

magick in.avif out.png

The PNG preserves decoded pixels, not the source image before AVIF compression.

AVIF to PNG by API or MCP

The HTTP API and the MCP server run the exact engine this page uses (Image engine); the response carries the same warnings the web converter shows. Check support first with GET /api/v1/pairs?from=avif&to=png.

curl

curl -X POST https://filetypeconverters.com/api/v1/convert \
  -H "Authorization: Bearer $FTC_API_KEY" \
  -F "file=@input.avif" -F "from=avif" -F "to=png" \
  -F 'options={"width":0}' \
  --output output.png

API reference

When this is the wrong conversion

Use AVIF → JPG when the destination needs broad photo compatibility and no transparency.
Keep AVIF for production web delivery if file size is the reason the asset exists.
Use the original design export if you need editable layers or vector artwork.

AVIF to PNG questions

Does AVIF → PNG keep transparency?

Yes in the measured alpha case. The output opened as RGBA and the corner pixel had zero alpha.

Why is the PNG larger than the AVIF?

PNG stores decoded pixels losslessly. AVIF's compact compression is lost when the image is expanded for editing compatibility.

Can AVIF → PNG recover original PNG metadata?

No. Metadata that disappeared during PNG → AVIF did not come back when we converted the AVIF to PNG.
