AVIF vs APNG: Format Comparison
Key differences between the two formats
| Feature | AVIF | APNG |
|---|---|---|
| Compression | Advanced AV1-based lossy/lossless | Lossless PNG compression |
| File size | Very small | Larger (lossless) |
| Animation | Supports AVIF sequences | Yes (native animated PNG) |
| Transparency | Full alpha channel | Full alpha channel |
| Browser support | Chrome, Firefox, Safari 16+ | Modern browsers (not IE) |
| Software compatibility | Limited (newer format) | Better than AVIF for PNG tools |
| Best for | Web photos, small file delivery | UI animations, browser-compatible animation |
When to Convert
Common scenarios where this conversion is useful
Converting for PNG-based animation workflows
Some animation tools and editors work with APNG but do not support AVIF. Converting an AVIF image to APNG makes it usable as a starting frame or asset in these workflows.
Ensuring transparency compatibility
APNG handles transparency with lossless PNG precision. If an AVIF image with transparency needs to be used in tools that accept PNG but not AVIF, APNG is the right output format.
Web fallback for browsers without AVIF support
For platforms that serve PNG or APNG as a fallback for non-AVIF browsers, converting your AVIF source to APNG provides the compatible version needed for progressive enhancement.
Integrating AVIF content into PNG pipelines
Legacy image processing pipelines built around PNG can accept APNG. Converting AVIF assets to APNG bridges the gap without changing the upstream pipeline.

Frequently Asked Questions
No. A single AVIF image converted to APNG produces a single-frame APNG — essentially a PNG with APNG metadata but no animation. To create an animated APNG you need multiple source frames and animation authoring tools.
If the source AVIF was lossy-encoded, converting to lossless APNG does not recover the original quality — you preserve what the AVIF stored. If the AVIF was lossless, the APNG output is pixel-for-pixel identical.
Yes. Both AVIF and APNG support full alpha channel transparency. Any transparent areas in your AVIF are preserved in the APNG output.
APNG is a superset of PNG — every APNG is also a valid PNG. If you specifically need APNG container format (for tools that check for it, or for future animation expansion), APNG is the right choice. Otherwise, plain PNG works just as well.
Yes. All major modern browsers (Chrome, Firefox, Safari, Edge) support APNG. Internet Explorer is the only major browser that does not.
Yes, typically much larger. AVIF compression is far more efficient than PNG. An AVIF that is 50KB might convert to a 500KB APNG or larger. This is a trade-off for broader compatibility.
No. ChangeThisFile processes everything in your browser using the Canvas API. Your AVIF file is never uploaded or transmitted anywhere.
All modern web browsers, GIMP, Photoshop (with plugin), and most image viewers that support PNG can open APNG files. The APNG animation data may be ignored by apps that only support static PNG.
The conversion runs in your browser and is limited only by your device memory. No hard file size cap is enforced.
This converter handles static AVIF images. For animated AVIF sequences, you would need specialized frame extraction tools before converting to APNG.
