AVIF to PNG Converter

What Is the AVIF to PNG Converter?

This tool converts an AVIF image to PNG entirely in your browser -- the file is decoded, redrawn onto a canvas, and re-encoded as PNG without ever being uploaded to a server. AVIF (AV1 Image File Format) is a modern image format built on the AV1 video codec, offering noticeably smaller file sizes than JPEG or WebP at the same visual quality. It's well supported for viewing in current Chrome, Firefox, Edge, and Safari, but many older tools, some email clients, and image editors still can't open it -- converting to PNG trades AVIF's smaller size for that universal compatibility.

How to Use This Tool

Click the upload area and choose an AVIF file. The converted preview appears immediately; click Download to save it as a real .png file.

Why Convert AVIF to PNG

The most common reason to convert AVIF to PNG is compatibility -- older software, some CMS/upload forms, and many image editors don't recognize AVIF at all, while PNG works everywhere and preserves transparency losslessly. It's also useful when you need to edit the image in a tool that has no AVIF support.

What Actually Happens to Your Image

Your browser decodes the AVIF file, the tool draws it onto a canvas at the image's own pixel width and height, and the canvas is encoded as PNG. Nothing is resized or color-adjusted by the tool. The result panel displays the pixel dimensions and the original file size followed by the PNG size, and the download keeps your filename with a .png extension. Because decoding is done by your browser, the tool can only open AVIF files that your browser itself supports.

Worked Example

Imagine a 1600 by 900 pixel AVIF hero image that is 120 KB. After conversion, the PNG will have the same 1600 by 900 pixel dimensions but is likely to be much larger, perhaps in the megabytes, since PNG is lossless and AVIF achieves its small size through aggressive, efficient lossy compression. The size badge in the tool shows the real figures for your file. If you only need the picture to open in software that does not understand AVIF, this trade is expected and acceptable.

Good Reasons to Convert

• An image editor, older operating system viewer or presentation program refuses to open AVIF.
• A content management system, marketplace or upload form only accepts common formats such as PNG or JPG.
• You need a lossless working copy for editing, so later saves do not compound compression loss.
• You want to send an image to someone whose email client or messaging app does not display AVIF.

What to Expect From the Output

• Transparency in the AVIF is kept in the PNG, since PNG supports a full alpha channel. The preview appears over a checkerboard so you can confirm this.
• The conversion does not add detail. Compression artifacts already present in the AVIF, such as smoothed textures, are frozen into the PNG as they appear.
• Metadata stored in the original file, like camera details, is not carried into the PNG, since only the decoded pixels are re-encoded.
• If you need a smaller output for photos, converting to JPG or WebP with one of the other tools may give a more practical file size than PNG.

Troubleshooting

• If you get an error that the image failed to load, your browser may not support AVIF, or the file may be damaged or not really an AVIF file. Try a current version of Chrome, Firefox, Edge or Safari.
• Very large images take longer and need more memory, because the conversion happens inside your browser tab.
• Animated AVIF files are not a supported use case for this tool; expect a single static image as output.
• Keep the original AVIF if you want the smallest possible file for web publishing. The PNG is a compatibility copy.

Why Only One Direction

This tool goes from AVIF to other formats only. Encoding to AVIF from a browser canvas is not consistently supported across browsers, so a converter offering that direction could silently produce a different format. For that reason, this page only reads AVIF and does not write it.
