How to Convert AVIF to PNG
Select your AVIF files
Click the upload area or drop one or more .avif images — batch conversion is supported.
Decoding in your browser
Your browser's built-in AVIF decoder reads each image, and it is re-saved as a lossless PNG on your device.
Download the PNGs
Save each converted image — now compatible with every editor and viewer.
What AVIF is and why files arrive in it
AVIF stores still images using the AV1 video codec's compression. It is the most efficient of the widely available image formats — commonly half the size of a comparable JPEG and smaller than WebP — and it supports transparency, wide colour gamuts and high dynamic range.
That efficiency is why sites have begun serving it, and why images saved from those sites arrive with an unfamiliar extension. Browsers display it; a great deal of other software still does not, which is the entire problem this conversion solves.
Converting is faithful but not free
The browser decodes the AVIF and writes the resulting pixels into a PNG losslessly, so the converted image matches what the AVIF displays. What it cannot do is undo AVIF's own compression: a lossy AVIF's artefacts are decoded faithfully and then stored exactly.
The size change goes the wrong way, and dramatically so. PNG storing a photograph losslessly can easily be ten times the AVIF it came from. That is the cost of a format everything can open, and it is why the PNG should be treated as a working copy rather than as the file you archive.
Colour and dynamic range
AVIF can carry wide-gamut and high-dynamic-range image data that ordinary PNG workflows do not preserve. Converting an HDR image produces a standard-range PNG, and the highlights that made the original striking are compressed into the range an ordinary display can show.
For the vast majority of images — screenshots, product photographs, illustrations — none of this applies and the conversion is visually exact. It matters only if the source came from an HDR photographic pipeline, in which case the AVIF is the better master and should be kept.
Transparency, and what to do afterwards
Alpha survives the conversion, so an AVIF with a transparent background becomes a PNG with the same transparency, ready for use in design software that cannot read AVIF directly.
Decoding happens in your browser using its built-in AVIF support, so nothing is uploaded. Keep the AVIF alongside the PNG: if the image ever goes back onto a web page, serving the original will be far better for load time than serving the much larger file you converted it into.
If PNG is more than you need
PNG is the safe destination because everything reads it, but it is not always the right one. For a photograph destined for another web page, WebP keeps most of AVIF's size advantage while being readable by far more software. For a photograph going into a document or an email, JPEG is smaller than PNG and universally accepted.
Choose PNG specifically when the image has transparency, when it contains text or flat graphics, or when it is going into software that demands a lossless import. For an ordinary photograph that simply needs to open somewhere, PNG is the largest possible answer to the question.
