AVIF to PNG Converter
Convert AVIF images into PNGs that preserve transparency and open in every editor, browser, and device.
What Is AVIF?
AVIF (AV1 Image File Format) is a modern image format built on the AV1 video codec, developed by the Alliance for Open Media (AOMedia). It delivers roughly 50% smaller files than JPEG at comparable visual quality, and supports transparency, HDR, wide color gamut, and up to 12-bit color depth.
Browser support for AVIF is now strong — over 93% of browsers in use today can display it — but adoption across the wider web is still under 1% of sites, so plenty of software still doesn't handle it.
Why Convert to PNG?
PNG is the safe, universal choice whenever you need to preserve transparency and hand an image to software that doesn't understand AVIF. Design tools, older image editors, icon generators, and many upload forms all expect PNG (or JPG) rather than AVIF, and PNG's lossless compression means nothing is lost in the conversion beyond what AVIF's own encoding already discarded.
How This Tool Works
This converter runs entirely in your browser using a real libavif decoder compiled to WebAssembly — the same underlying decode technology browsers use natively. Your AVIF file is decoded and re-encoded as a PNG entirely on your device, with any transparency preserved; it's never uploaded to any server. Larger or higher-resolution images take a little longer to process since AVIF decoding is more computationally intensive than older formats.
AVIF vs PNG — When to Use Each
| Feature | AVIF | PNG |
|---|---|---|
| File size | Much smaller for photos | Larger, especially for photos |
| Compression | Lossy or lossless | Always lossless |
| Transparency | Supported | Supported |
| Best for | Photos and complex images | Graphics, screenshots, logos, transparency |
| Color depth | Up to 12-bit | Up to 16-bit |
| Compatibility | ~93% of browsers, ~1% of websites actually use it | Universal — every device, browser, and editor |
| Editing software | Limited support, growing | Universal |
Keep AVIF When
- Serving photos on your own website to modern browsers
- File size and load time matter more than maximum compatibility
- You need HDR or wide-color-gamut image data preserved
Convert to PNG When
- Uploading to design tools, icon generators, or editors that don't accept AVIF
- You need guaranteed-lossless output for further editing
- Transparency needs to survive in software with no AVIF support
- Sharing with someone whose device may not open AVIF
Common Scenarios for AVIF to PNG Conversion
Preserving Transparency
If your AVIF image has transparent areas and you need to hand it to software that doesn't support AVIF, PNG is the format that keeps that transparency intact — unlike JPG, which fills transparent areas with white.
Uploading to Design Tools
Many design and icon-generation tools still don't accept AVIF, but virtually all of them accept PNG. Converting first avoids compatibility errors and lets you keep editing.
Working with Logos and Graphics
AVIF isn't always ideal for flat-color graphics, icons, or logos with sharp edges — PNG's lossless compression handles that kind of image more predictably, and is what most design workflows expect.
Sharing with Older Devices or Software
Not every device or application can open AVIF yet. PNG is universally supported, so converting first guarantees the recipient can view the image without issues.
Archiving with Guaranteed Compatibility
If you're storing images long-term and want a format you're confident will still open in a decade, PNG's decades-long track record makes it a safer archival choice than a newer format. For a compact archive of several converted images, combine them into a single file with Image to PDF.
Other Ways to Convert AVIF to PNG
You can also convert AVIF to PNG using your device's built-in photo viewer (File → Export or Save As), or an image editor like GIMP or Photoshop. FileCast is useful when you want a quick conversion without opening a separate app.
Frequently Asked Questions
Is it safe to convert my images here?
Yes. This tool decodes and re-encodes your AVIF file entirely in your browser, using a WebAssembly build of the same libavif decoder browsers use natively. Your image is never uploaded to a server — when you close the tab, all data is gone.
Does converting to PNG reduce image quality?
No. PNG is a lossless format, so the pixel data from the decoded AVIF is preserved exactly. Any quality loss already happened when the image was originally encoded as AVIF — converting to PNG doesn't add any further loss.
Is transparency preserved?
Yes. Unlike converting to JPG, converting AVIF to PNG keeps any alpha channel (transparency) in your original image fully intact.
Will the file size increase after conversion?
Usually, yes, and often significantly. AVIF is a much more efficient compression format than PNG, especially for photographic content, so converting typically produces a noticeably larger file for the same image.
Why does conversion take a moment for some files?
AVIF decoding is more computationally intensive than older formats. Larger or higher-resolution images take longer to process. Everything still happens on your device — there's no upload involved, just more work for your browser to do.
