AVIF to PNG Converter
FileFlip converts AVIF to PNG entirely inside your browser, using ImageMagick compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert an AVIF file to PNG?#
- Drop your AVIF file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to PNG and the conversion starts on its own. FileFlip downloads 14.1 MB of WebAssembly the first time and nothing after that, then runs ImageMagick on your own machine.
- Save the PNG file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting AVIF to PNG lose quality?#
PNG is a lossless format, so nothing further is lost here, but nothing is recovered either. Whatever the AVIF encoder already threw away is gone, and the PNG file will usually be several times larger for exactly the same content.
Is it safe to convert AVIF files online?#
Yes, because nothing is uploaded. FileFlip converts AVIF files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.
What AVIF to PNG actually does to the file#
Converting AVIF to PNG runs on ImageMagick, downloads 14.1 MB of WebAssembly the first time and nothing after that, writes a lossless file that cannot recover what the source already discarded, keeps EXIF metadata, ICC colour profile and transparency, and drops animation frames and extra images.
| Engine | ImageMagick |
|---|---|
| Conversion path | One step: AVIF → PNG |
| Downloaded to your browser | 14.1 MB, once, then cached by your browser |
| Quality | Lossless output, but nothing is recovered |
| You get back | One file |
| Where it runs | In a background worker, so the page stays responsive |
What survives the conversion
| What is in the file | This conversion | Why |
|---|---|---|
| EXIF metadata | Kept | Carried through into the converted file. |
| ICC colour profile | Kept | Carried through into the converted file. |
| Transparency | Kept | Carried through into the converted file. |
| Animation frames | Dropped | The target format has nowhere to put it. |
| Extra images | Dropped | The target format has nowhere to put it. |
Worth knowing before you start:
- ImageMagick is asked for a single image, so only the first frame, page, or icon size is read
What is an AVIF file?#
An AVIF file holds a still image or short animation encoded with the AV1 video codec, packaged inside a HEIF-style container that also carries HDR and wide-colour-gamut data alongside the pixels.
Use AVIF for web images where file size matters most, since it now decodes natively in every major browser and beats JPEG and WebP on compression at the same quality.
Convert AVIF to JPEG or PNG when a file is headed somewhere that still rejects it, such as an older content management system, a print workflow, or an app without AV1 decoding.
What is a PNG file?#
A PNG file stores a raster image using lossless DEFLATE compression, which is why screenshots, logos, and graphics with flat colour or sharp edges use it instead of JPEG.
Use PNG for screenshots, logos, icons, and any graphic with flat colour or transparency, where exact pixel reproduction matters more than file size.
Convert PNG to JPEG or WebP when the image is a photograph and file size matters more than pixel-perfect reproduction, since a photographic PNG is typically several times larger than an equally sharp lossy file.
AVIF to PNG questions people ask#
Why won't a website accept my AVIF upload?
Plenty of older content management systems, forums and stock photo sites still only recognise JPEG, PNG and sometimes WebP, because AVIF support was added to their upload validators later or not at all. Converting the AVIF to JPEG usually clears the block immediately.
What is an AVIF file?
An AVIF file is an image compressed with the AV1 video codec instead of the older JPEG or WebP algorithms, which is why it produces noticeably smaller files at the same visual quality. It was created by the Alliance for Open Media, the same group behind the AV1 video format, and first shipped in 2019.
Do browsers support AVIF now?
Yes. AVIF decodes natively in Chrome, Edge, Firefox and Safari, and caniuse.com puts global browser support above 94% as of mid-2026. That makes it safe to use directly in a website without a JPEG fallback for most audiences.
Is AVIF better than WebP?
AVIF generally compresses photographic images smaller than WebP at the same visual quality, and it supports higher bit depth and HDR, which WebP does not. WebP still encodes faster and has been supported in browsers for longer, which is why some tools default to it.
