PNG is the format you reach for when an image needs to survive whatever happens next — editing, cropping, pasting into a slide deck, or being handed to a tool that predates modern codecs. AVIF, meanwhile, is what modern websites and export pipelines increasingly hand you, whether you asked for it or not. Screenshots saved by newer tools, assets delivered by a designer, images pulled from a CDN: more and more of them arrive as .avif, and plenty of software still refuses to open them.
Converting to PNG here is a lossless operation. Your browser decodes the AVIF using WebAssembly, then writes every pixel of the decoded image into a PNG without discarding anything. If the file has an alpha channel, it carries over exactly — semi-transparent edges, soft shadows, and fully transparent regions all survive. There are no compression decisions to make, because PNG compression never throws away image data, and the result opens in practically anything: image editors from any era, office software, upload forms, game engines.
One expectation to set: file size. AVIF is among the most efficient image codecs in common use, and PNG is among the least when it comes to photographs, so a photo converted this way can grow to many times its original size. For screenshots, diagrams, logos, and other flat-color graphics the gap is much smaller — and those are exactly the images PNG was designed for. Also worth knowing: AV1 decoding takes real computation, so a very large AVIF may need a few seconds before your PNG appears.
None of this involves a server. The converter is free, requires no signup, and processes the image entirely on your device — the file is never transmitted anywhere. If you are converting something sensitive, a screenshot of an internal dashboard or a private photo, it stays exactly as private as it was before you opened this page.
Why convert AVIF to PNG?
- PNG is lossless, so nothing beyond the original AVIF compression is ever lost
- Full alpha-channel transparency carries over exactly, including partial transparency
- Every image editor, office suite, and CMS in existence accepts PNG
- Ideal for screenshots, logos, and graphics you plan to keep editing
How it works
- Step 1
Drop your files
Drag your AVIF files into the converter above, or click “Choose files”. Batches are welcome.
- Step 2
Pick your settings
PNG is preselected. Adjust quality or size if you want, or keep the defaults.
- Step 3
Convert and download
Conversion runs locally in your browser. Download files individually or grab everything as a zip.
Frequently asked questions
- Does this tool send my image to a server to convert it?
- No — there is no server side at all. The AVIF decoder and PNG encoder are compiled to WebAssembly and run inside the browser tab. The engine downloads once (about 5 MB) on first use and is cached by your browser after that — your images themselves never travel anywhere.
- Is AVIF to PNG conversion really lossless?
- The conversion step is. PNG stores the decoded pixels exactly, so nothing is lost between the AVIF you drop in and the PNG you get back. Keep in mind that most AVIF files were themselves saved with lossy compression, and converting cannot recover detail the AVIF never contained — it just guarantees no further loss.
- Will transparency be preserved?
- Yes, completely. Both formats support a full alpha channel, so transparent and semi-transparent pixels convert one-to-one. This makes PNG the right target for logos, cutouts, and interface assets that came to you as AVIF.
- Why did my file get so much bigger?
- Because the two formats sit at opposite ends of the compression spectrum. AVIF uses aggressive, modern lossy compression; PNG stores data losslessly. For photographs the size increase is normal and unavoidable. If small size matters more than lossless storage, converting to WebP or JPEG instead will produce far smaller files.
- What about HDR or 10-bit AVIF files?
- AVIF can store 10-bit and HDR imagery, but the output here is a standard PNG, so the extended brightness range will not carry through. The image itself converts fine — it will simply display as a normal standard-dynamic-range picture, which can look a little flatter than the HDR original.
