How to use this AVIF to PNG converter
- Add your .avif files to the dropzone, or press Browse files to choose them.
- Confirm the queue looks right, names and sizes are listed for each file.
- Press Convert to PNG. There are no settings, because PNG encoding is lossless.
- Review the size change beside each result before downloading.
- Save the images one by one, or take the whole batch as a ZIP.
Why convert to PNG rather than JPG
- Keeps the alpha channel intact, so cut-outs and logos stay transparent.
- Adds no second round of lossy compression on top of what AVIF already applied.
- Produces a file that opens in every editor, viewer and upload form in existence.
- Handles batches of twenty images with a progress bar and per-file reporting.
- Leaves resolution untouched, so a large source stays large.
- Runs entirely offline once the page has loaded, with no account or limit.
The case for a lossless intermediate
AVIF earns its place on live websites, where every kilobyte affects how fast a page paints. It is a poor working format. Editors that support it are still uncommon, colour handling varies between implementations, and re-saving a lossy file repeatedly compounds compression damage in exactly the way you want to avoid while you work.
Converting to PNG puts the image into a state where none of that applies. PNG stores the decoded pixels exactly, so you can crop, mask, recolour and export a dozen times with the file identical at every step. It is the sensible destination whenever an AVIF is an input to more work rather than a finished asset.
Situations where this is the right conversion
- A logo or icon downloaded from a modern site that needs to keep its transparent background.
- Artwork heading into a design tool that does not list AVIF among its import formats.
- Assets for an application bundle, where the build pipeline expects PNG resources.
- Images for a document template that renders PNG reliably and AVIF not at all.
- Any case where you want a decoded archival copy that does not depend on a young codec.
Understanding the size jump
This conversion produces the largest increase of any in the category. AVIF is the most efficient format here and PNG is among the least efficient for photographic content, so a 300 KB AVIF becoming a 4 MB PNG is entirely ordinary. Nothing has gone wrong; you have simply traded compression for compatibility and editability.
Flat graphics behave much better. Logos, icons, charts and interface screenshots use a limited palette that PNG compresses well, and those files often grow only modestly. If the result is still unwieldy, the PNG compressor reduces the palette where it can do so invisibly, and the image resizer makes a far bigger difference than any encoder setting when the source is larger than it needs to be.
Transparency, colour and dynamic range
Both AVIF and PNG carry a full alpha channel, so transparency survives this conversion untouched. That is the main reason to prefer PNG over JPG here. A JPEG would force every transparent pixel onto a solid colour.
Colour is slightly more nuanced. AVIF can describe wide gamuts and high dynamic range; the PNG this tool produces is standard 8-bit-per-channel sRGB, because that is what a browser canvas exports. For ordinary web graphics that is exactly right and you will notice nothing. For an HDR photograph, expect the converted copy to look a little flatter than the original did on a display capable of showing it.
Local by design
The AVIF file is decoded by your browser, painted onto an off-screen canvas and encoded as PNG in this tab's memory. There is no upload, no server-side queue and no retention policy to read, which is why the tool keeps working when the connection drops. If a compact result matters more than losslessness, the AVIF to JPG converter is the better companion, and WEBP to PNG solves the same problem for the previous generation of web images.
