AVIF to PNG converter: a lossless copy with transparency intact
AVIF files are impressively compact, but plenty of editors, older apps, and upload forms still refuse to open them. Offcloud converts your AVIF images to PNG right in your browser, giving you a lossless, universally supported copy. It is completely free, requires no signup, and your files never leave your device.
Why convert an AVIF image to PNG?
AVIF has become a favorite on the modern web because it packs excellent image quality into very small files. The catch is that support outside browsers is still patchy: many photo editors, design tools, office suites, and website upload forms simply do not recognize the format. Converting an AVIF to PNG removes that friction instantly, because PNG opens everywhere, from decade-old software to every operating system's default viewer.
PNG is the right choice for two situations in particular. If your image has transparency, such as a logo, an icon, a sticker, or a UI element, PNG preserves the alpha channel exactly, and because PNG is lossless, it makes an ideal working copy for further editing with no extra degradation between saves. For a plain photo with no transparency, a JPG usually produces a much smaller file, so pick the output that matches what you actually plan to do with the image.
Decoded in the browser, saved on your device
Your unreleased designs, client assets, and private photos stay on your machine from start to finish: the AVIF is decoded and rewritten as a PNG by the browser itself, using WebAssembly and its built-in canvas. Nothing is uploaded to a server, nothing is stored online, and nothing remains once the conversion is done.
This local approach also keeps things simple: everything is free, you never create an account, and the PNG you download carries no watermark. Because no server ever touches your file, there is no server-imposed file-size cap either; the only practical limit is your device's memory, and it works in any modern browser on desktop or mobile.
Lossless means faithful, not improved
PNG is a lossless format, so the file you download is a pixel-for-pixel copy of what your AVIF decodes to, and it will not degrade further no matter how many times you edit and re-save it. Be aware, though, that no conversion can improve the original: if the AVIF was compressed aggressively, that detail is gone for good, and the PNG will faithfully preserve the image as it is, artifacts included.
Count on a real size increase: PNG's lossless compression simply cannot match AVIF's efficiency, and that gap is the price of universal compatibility and clean editing. Very large images may take a little longer to process on modest hardware, so keep the tab in the foreground and let it finish. It is also worth keeping the original AVIF as a compact archive copy. Finally, remember to convert only images you own or have the rights to use.
Conversion steps
- Open Offcloud in your browser and select your AVIF image, or simply drag and drop it onto the page.
- Choose PNG as the output format.
- Let the conversion run directly in your browser; your file is never uploaded to any server.
- Download the finished PNG to your device as soon as the conversion completes.
Frequently asked questions
Does converting an AVIF to PNG preserve transparency?
Yes. If your AVIF contains an alpha channel, the transparency is carried over to the PNG exactly as it was, which makes this conversion ideal for logos, icons, and other cut-out graphics.
Why is the PNG so much larger than my original AVIF?
AVIF is one of the most efficient image formats available, while PNG stores every pixel losslessly. A significant size increase is completely normal and is the trade-off for a file that opens everywhere and survives repeated editing.
Will converting to PNG improve my image quality?
No. A conversion can never add back detail that AVIF compression already removed. The PNG is an exact, lossless copy of the decoded AVIF, so it looks identical to the source, no better and no worse.
Do I need an account to convert AVIF files to PNG?
No. Offcloud is entirely free, with no signup, no account, and no watermark on your converted PNG files.
Are my AVIF images uploaded to a server during the conversion?
Never. The entire conversion runs locally in your browser, so your images stay on your device from start to finish and nothing is stored online. That is also why there is no server-imposed size limit, only your device's available memory.
