What is PNG to AVIF conversion?
A 2 MB infographic PNG routinely comes out between 100 and 200 KB as AVIF with nothing perceptibly lost. That number is the whole argument, and it holds because AVIF is the still-image profile of the AV1 video codec — standardised by the Alliance for Open Media AV1 specification, royalty-free for commercial use, and currently the strongest compressor in general browser deployment. It keeps the two PNG features graphics work depends on, full alpha channel transparency and a lossless mode, and adds two PNG never had: wide colour gamut (Display P3, Rec. 2020) and HDR. Sites serving high-resolution graphics, data visualisations, charts, or product images on transparent backgrounds stand to gain the most, simply because those assets are usually the heaviest payload on the page. Total image weight commonly falls 60-80% against PNG. The HTML picture element keeps the rollout low-risk: AVIF first, PNG fallback for the small remainder of users on older browsers. The bill arrives at encode time. libaom typically needs 3-10 seconds per image depending on resolution and effort level, because the codec leans on non-square transform blocks, multi-reference prediction, and adaptive deblocking. That is a one-time build-step cost, repaid on every single page load afterwards. Browser support runs to 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.
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.
