PNG is lossless and keeps transparency, so it is often larger than the same image as JPG or WebP.

What is a AVIF to PNG converter?
An AVIF to PNG converter decodes an AVIF image and writes the same picture back out as a PNG. People reach for PNG rather than JPG in two situations: the image has transparent areas that have to survive, and the file is going into an editor, a slide deck or a build pipeline where every later save should be lossless. A logo, an icon, a UI screenshot or a cut-out product shot saved from a site as .avif is the usual case.
PNG is the right target for transparency because it has a real alpha channel, so a transparent background stays transparent instead of turning into a white rectangle. It is also the right target when the file will be opened and saved repeatedly, since PNG stores pixels exactly and does not lose a little more each time. What PNG cannot do is undo anything: AVIF is a lossy format, so the PNG is a perfect copy of what the AVIF decoded to, not of whatever the image looked like before it was compressed.
Expect the file to grow, often by a lot. Take a 1,200 x 1,200 product cut-out that a site serves as a small AVIF. Drop it here and it converts straight away: you get the same 1,200 x 1,200 pixels with the transparency intact, and the row shows the size before and after and how much larger the PNG is. Nothing has gone wrong; AVIF spends clever, lossy compression on that picture while PNG describes every pixel losslessly, and there is no quality slider on this page because a lossless format has nothing to trade.
The rest is worth knowing before you convert a batch. Decoding is handled by the browser itself, so AVIF needs a current one: Chrome, Edge, Firefox, or Safari 16 and later. Files that the browser cannot open are reported on their own row rather than failing quietly. The image is redrawn through a canvas, which drops EXIF, GPS and embedded color profiles. Pixel dimensions are untouched. Anything over 100 megapixels is refused with a message, empty files are refused, and there is no byte-size cap. Everything happens client-side, and it is free, no signup, with a daily usage limit.
How to convert AVIF to PNG
Add your AVIF files
Drag them onto the area marked "Drop AVIF images here or click to upload", or click it and pick them. Several files at once is fine, each one starts converting as soon as it is added, and the format is read from the file contents rather than the extension.
Adjust settings if you need to
There is no quality setting to choose, because PNG is lossless, so the results are already on their way in the file list. The panel shows AVIF to PNG and a short note on what PNG keeps.
Check each result
Each row shows a thumbnail, its status and a size line with the size before and after and how much smaller or larger the PNG is, so you can see straight away how much the PNG grew. Click the thumbnail to open the PNG large and switch between Before and After. The X on a row removes that file and Clear All empties the list, which is quicker than reloading when you grab the wrong folder.
Download the results
The download icon on a row saves that file under its original name with a .png extension. Download All (n images) in the list header produces converted-png.zip, and duplicate names are numbered inside it.
Why convert AVIF to PNG?
PNG is the choice when the image matters more than the file size. Three situations make that trade worth it.
The background has to stay transparent
Logos, icons, stickers and cut-out product shots are often served as AVIF with an alpha channel. PNG is the widely supported format that keeps that alpha intact, including the soft, partly transparent pixels along a curved edge or a shadow.
Converting the same file to JPG would place it on a white rectangle, which is fine on a white page and obvious on anything else.
The file is going into an editor
Design tools, slide software and screenshot annotators open PNG without complaint, and PNG does not lose anything when it is saved again. Turning the AVIF into a PNG once gives you a stable master copy that survives any number of edits.
A pipeline or template expects PNG
App icon sets, documentation builds, sprite sheets and a lot of print templates are written around PNG input. An AVIF dropped into one of them tends to fail at build time or show up as a missing image. If the image is headed for a browser tab icon rather than a template, make an ICO from a PNG after this step.
AVIF vs PNG: which to use
| AVIF | PNG | |
|---|---|---|
| Compression | Usually lossy, sometimes lossless. Very efficient on photos and gradients. | Always lossless. Every decoded pixel is stored exactly. |
| Transparency | Full alpha channel. | Full alpha channel. Transparency carries over unchanged on this page. |
| Animation | The format allows image sequences; this converter reads AVIF as a still. | A standard PNG is a single still image, which is what this page writes. |
| Color depth | 8, 10 or 12 bits per channel, including HDR. | Up to 16 bits per channel in the format. Output from this page is 8 bits per channel. |
| Typical file size | Very small for its visual quality. | Much larger for photos, often many times the AVIF. Closer for flat graphics. |
| Browser and software support | Current browsers; patchy in desktop apps and older systems. | Supported by essentially every browser, editor and operating system. |
| Best for | Delivering images on the web at the lowest byte cost. | Editing, archiving, logos and icons, and anything that must keep its transparency. |
What a lossless copy of a lossy file keeps
A PNG made from an AVIF is exact, but exact to the decoded AVIF, not to the photo or artwork the AVIF was made from. If the site that served the file compressed it hard, the smudged texture and soft edges are part of the pixels now, and PNG preserves them faithfully. That is why the conversion never makes an image look better, and why the file grows: PNG has to spell out the compression artifacts pixel by pixel as well.
Some things do change. AVIF can hold 10 or 12 bits per channel and wide-gamut or HDR color. The browser canvas this page draws on works in 8-bit sRGB, so a high bit depth AVIF is reduced to 8 bits per channel on the way through, and a wide-gamut image may look slightly less saturated than the original. For the ordinary 8-bit sRGB AVIFs most websites serve, there is no visible difference.
Transparency is the part that carries over best. Both formats have a full alpha channel, so a feathered shadow or an anti-aliased edge keeps each of its partly transparent pixels, which the Before and After views in the preview show against a checkerboard when you click a row's thumbnail.
Privacy and security
- The conversion is client-side. The browser decodes the AVIF and the Canvas API writes the PNG inside this tab, with no WebAssembly codec and no upload.
- For the daily limit, the page sends only how many files converted, their total size in bytes and the target format. File names and image pixels stay on your device.
- No copy of the AVIF or the PNG is kept on a server. Results sit in the tab's memory until you remove them, press Clear All or close the page.
- The PNG carries no EXIF, GPS or embedded color profile from the AVIF, because it is encoded from the decoded pixels alone.
- A file that is not an AVIF is identified from its first bytes, and a file in another format is turned away with a link to the converter that handles it.
Key Features
Transparency survives
PNG has an alpha channel, so transparent areas in the AVIF stay transparent. Nothing is flattened onto a white background the way a JPG conversion has to.
Lossless output
The PNG encoder stores the decoded pixels exactly, so opening and re-saving the file later does not degrade it further.
Runs client-side
Images are decoded and re-encoded in the browser tab. No image data is sent anywhere; only the number of files and their total size is recorded, for the daily limit.
Batch to a single ZIP
Add a whole folder, let it convert in one pass and take the lot as converted-png.zip with Download All instead of saving each file by hand.
