AVIF to PNG
Convert AVIF to lossless PNG in your browser, transparency preserved. Free, private, no upload, no watermark.
About this tool
Converting AVIF to PNG gives you a lossless, universally supported copy of the image with transparency intact. The whole conversion runs in your browser; the file is never uploaded.
Choose PNG over JPG when the AVIF has a transparent background or when you plan to edit the image further and do not want to stack lossy re-encodes.
Common uses
- Preserve transparency in icons and graphics saved as AVIF
- Get a lossless working copy of an AVIF before editing
- Convert AVIF assets for tools and pipelines that expect PNG
Automate via API
The same conversion is available as a REST endpoint for scripts, pipelines, and backends. POST the file, get the converted file back:
curl -X POST https://formatably.com/api/v1/tools/avif-to-png \ -H "X-Api-Key: YOUR_API_KEY" \ --data-binary @photo.avif \ -o photo.png
Direct requests accept up to 4 MB; the large-file flow handles up to 100 MB. Both are covered in the API documentation · Get an API key
AVIF notes
AVIF is the image format derived from the AV1 video codec, offering the best compression of any mainstream format. Browsers and CDNs increasingly serve it, but most editors, upload forms, and older software cannot open it.
- Right-click-saving an image from a modern website often yields AVIF even when the page showed it as a JPG.
- Converting AVIF to JPG or PNG grows the file; that is expected, AVIF is simply that efficient.
- Very old browsers cannot decode AVIF; this tool needs a 2023-or-newer browser.
PNG notes
PNG is the lossless workhorse: screenshots, logos, UI graphics, and anything needing transparency. Every device and program on earth opens it. The tradeoff is size: photos stored as PNG are several times larger than JPEG.
- PNG is lossless, so converting into PNG never loses quality, but converting a photo to PNG can triple its size.
- Transparency is preserved in PNG; JPG has no transparency at all.
Frequently asked questions
Does this work in every browser?
AVIF decoding requires a reasonably recent browser: Chrome 85+, Firefox 93+, Safari 16.4+. On anything current it works out of the box.
Is AVIF to PNG lossless?
The PNG step is: every pixel decoded from the AVIF is stored exactly, including the alpha channel. Any loss in the AVIF itself happened when it was created and cannot be reversed by any converter.
Are my files uploaded to a server?
No. The conversion runs entirely in your browser using WebAssembly and the canvas API; your files never leave your device. There are no ads and no trackers on tool pages. You can verify this yourself: open your browser's developer tools, watch the Network tab while converting, and you will see no upload requests. It even works offline once the page has loaded.
Is there a file size limit?
In the browser there is no hard limit; you are bounded only by your device's memory, and files of a few hundred megabytes are usually fine. The REST API accepts files up to 4 MB in a direct request, or up to 100 MB using the large-file upload flow described in the API docs.
