To convert AVIF to PNG online, add your AVIF files above, press Convert and download the PNG files. PNG is lossless and keeps transparency. HDR and 10-bit images are reduced to standard 8-bit colour. Everything runs in your browser; nothing is uploaded.
Convert AVIF images to PNG to keep every pixel and any transparency in a format that all software understands, ideal for editing and archiving. It is a free tool from Websolindia, a New Delhi website design and SEO company that builds fast, image-optimised websites.
Unlike most online converters, this tool does not upload your images. Your browser decodes each AVIF file, converts it and creates the PNG file on your own device. That keeps private photos private, avoids upload waits and keeps working on a slow connection once the page has loaded. You can convert up to 50 files at a time and download them one by one or together as a ZIP.

This table compares the two formats so you can decide whether converting is the right move.
| Feature | AVIF | PNG |
|---|---|---|
| Full name | AVIF (AV1 Image File Format) | PNG (Portable Network Graphics) |
| Origin | Specified by the Alliance for Open Media in 2019 | W3C Recommendation in 1996 |
| Compression | Lossy and lossless | Lossless |
| Transparency | Yes | Yes, full alpha (256 levels of transparency) |
| Animation | Yes | No (animated PNG is a separate extension) |
| Colour depth | 8, 10 and 12 bits; HDR capable | Up to 16 bits per channel |
| Typical file size | Often the smallest of the common formats | Large for photos, small for flat graphics |
| Best for | High-quality web images where file size matters most | Logos, screenshots, graphics and anything needing transparency |
| Browser support | Chrome 85+, Firefox 93+, Safari 16.4+, Edge 121+ | Every browser, app and device |
| File extension | .avif | .png |
File size: PNG is typically much larger than AVIF, because AVIF is among the most efficient formats and PNG is lossless.
This is exactly what happens to your file. Nothing is hidden, and you can verify that nothing is uploaded by watching your browser's network tab while you convert.
| Step | What happens |
|---|---|
| 1. Read the file locally | Your browser reads the file from your device into memory. Nothing is sent to a server. |
| 2. Identify the format | We check the file's first bytes (its signature) instead of trusting the extension, so a PNG renamed to .jpg is still handled correctly. |
| 3. Decode the AVIF to pixels | The image is decoded to raw red, green, blue and alpha pixels using your browser's built-in AVIF decoder (a bundled WebAssembly decoder steps in if the browser has none). |
| 4. Resize (optional) | If you set a maximum width, larger images are scaled down with an area-weighted filter. Images are never enlarged, and the proportions are always kept. |
| 5. Keep transparency | Transparency passes straight into the PNG file, because PNG supports it. |
| 6. Encode the PNG | The pixels are written out as PNG using your browser's PNG encoder (lossless). Metadata such as camera details and location is not copied. |
| 7. Report the result | We show the dimensions, the sizes before and after, and the change: (new size − original size) ÷ original size × 100. For example, 500 KB becoming 350 KB is −30%. |
| Setting | Default | Range | What it does |
|---|---|---|---|
| Maximum width | None | 1–20,000 px | Scales larger images down. Never enlarges. |
| What | Formula | Notes |
|---|---|---|
| Size change | (new − original) ÷ original × 100 | Shown for every file. Negative means smaller. |
| Downscale factor | min(1, maximum width ÷ width) | Applied only when you set a maximum width; never above 1. |
Speed depends on your device and the image size. In our Chrome tests on a desktop-class processor, a 6-megapixel photograph took about 2 seconds to convert to WebP or PNG. AVIF is the slowest: about 2.5 seconds on Fast and about 7.5 seconds on Balanced. Phones and older laptops take longer, and images over about 120 megapixels are declined rather than risking a frozen browser.
| Format | Where it opens | Typical use |
|---|---|---|
| AVIF | Chrome 85+, Firefox 93+, Safari 16.4+, Edge 121+ | High-quality web images where file size matters most |
| PNG | Every browser, app and device | Logos, screenshots, graphics and anything needing transparency |
| This converter | Current Chrome, Edge, Firefox and Safari. Needs JavaScript and WebAssembly | Private conversion on your own device |
Yes. AVIF supports transparency, and PNG stores it with a full alpha channel, so transparent areas are kept.
The conversion adds no loss: PNG stores the decoded AVIF pixels exactly. Any loss that was already in a lossy AVIF remains.
AVIF throws away invisible detail to be tiny, while PNG keeps every pixel. For smaller photos, use the AVIF to JPG Converter Online.
They are converted to standard 8-bit colour, so extreme highlights and subtle gradients can look slightly flatter.
Yes, with the PNG to AVIF Converter Online, which brings the file size back down while keeping transparency.
No. Width and height stay the same unless you set a maximum width, which only scales large images down.
Yes. It is free, needs no sign-up, adds no watermark and has no daily limit. You can convert up to 50 AVIF files in one go. It is provided by Websolindia.
No. Your AVIF files are read and converted inside your browser, on your own device. They are never sent to Websolindia or anyone else, which is why this converter is safe for private photos and documents.
Yes. The new file is created from the decoded pixels, so camera details, GPS location and other embedded metadata are not copied. If you need to keep metadata, use a desktop editor.
Up to 50 files per batch and 150 MB per file. Images above roughly 120 megapixels are declined with a clear message rather than freezing your browser.
Current versions of Chrome, Edge, Firefox and Safari. It also needs WebAssembly, which all of those browsers include.
