What is PNG to AVIF conversion?
AVIF is the still-image profile of the AV1 video codec, standardised by the Alliance for Open Media AV1 specification and royalty-free for commercial use. It is the current state of the art in image compression, beating both WebP and JPG by significant margins.
For PNG sources the gains are dramatic: a 2 MB infographic PNG often becomes a 100-200 KB AVIF with no perceptible quality loss. Crucially for graphics work, AVIF carries forward features PNG shares — full alpha channel transparency, lossless mode — and adds wide colour gamut support (Display P3, Rec. 2020) and HDR that PNG cannot represent. PNG-to-AVIF is particularly compelling for sites serving high-resolution graphics, data visualisations, charts, or product images with transparent backgrounds. These assets are typically the heaviest payload on a page, and AVIF can cut total image weight by 60-80% versus PNG. The HTML picture element makes it straightforward to serve AVIF first with a PNG fallback for the small percentage of users on older browsers. The trade-off is encoder cost. AVIF encoding via libaom is computationally intensive — typically 3-10 seconds per image depending on resolution and effort level — because the codec uses non-square transform blocks, multi-reference prediction, and adaptive deblocking. This is a one-time build-step cost that pays back on every page load. Browser support covers Chrome 85+, Firefox 93+, and Safari 16+ per caniuse.com/avif, which represents the vast majority of global traffic in 2026.
Why convert PNG to AVIF?
- AVIF is 50% smaller than JPG and 30% smaller than WebP at similar quality
- Supports transparency, HDR colour, and wide colour gamut
- Supported by Chrome, Firefox, and Safari 16+
- Dramatically reduces bandwidth usage and improves page load speed
What is the difference between PNG and AVIF?
The table below compares PNG vs AVIF across key format characteristics.
| Feature | PNG | AVIF |
|---|---|---|
| File extension | .png | .avif |
| Compression type | Lossless | Lossy and lossless |
| Transparency support | Yes (alpha) | Yes (alpha) |
| Animation support | No | Yes |
| File size | Larger | Smallest |
| Best use case | Graphics, transparency | High-quality web |
| Browser support | Universal | Chrome 85+, Safari 16.4+ |
Use PNG for universal support and transparency; choose AVIF for the smallest possible web images.
Frequently asked questions
Is AVIF widely supported by browsers?
AVIF is supported by Chrome 85+, Firefox 93+, and Safari 16+. It covers the vast majority of current browser usage. For older browsers, keep a PNG or WebP fallback.
How does AVIF compare to WebP?
AVIF typically achieves 20-35% smaller files than WebP at the same quality, especially for photographic images. WebP still has broader software support.
Does AVIF support transparent backgrounds?
Yes. AVIF supports alpha channel transparency, so PNG images with transparent backgrounds will retain transparency in the AVIF output.
Should I use AVIF or WebP for my website images?
AVIF produces 20-35% smaller files than WebP but encodes more slowly and has slightly less browser support. Ideal strategy: serve AVIF as the primary source with a WebP or JPG fallback using the HTML picture element. Use the PNG to WebP converter to create the fallback.
Can AVIF preserve the wide colour gamut of my professionally calibrated PNG images?
Yes. AVIF supports ICC profiles and wide colour gamuts including Display P3 and Rec. 2020. If your PNG contains an embedded colour profile, the AVIF output preserves it. This makes AVIF one of the few web formats suitable for colour-critical work like photography portfolios and product catalogs.
Why does AVIF encoding take longer than WebP or JPG?
The AV1 codec uses more sophisticated compression techniques including multi-reference prediction, advanced intra-frame coding, and larger transform blocks. These require more computation but produce substantially smaller files. The encoding cost is one-time; the bandwidth savings apply to every user who loads the page.
Will my PNG infographic with text and charts convert well to AVIF?
Yes, and this is one of AVIF's strengths. Unlike JPG, which struggles with sharp text and hard edges, AVIF handles mixed content (text, charts, photographs, gradients) in a single image very efficiently. Text remains crisp and charts stay sharp even at aggressive compression settings.
Should I use lossy or lossless AVIF for a transparent PNG logo?
For a brand logo where pixel fidelity matters more than every byte, lossless AVIF is appropriate and still typically smaller than the source PNG. For decorative graphics, hero illustrations, and photographic content with transparency, lossy AVIF at a high quality setting yields dramatically smaller files with no visible difference. This converter targets high-quality lossy AVIF by default for the best size-quality balance.
