Why convert PNG to AVIF?
PNG files with transparency can be enormous, logos, product images, and UI assets often weigh 500KB-5MB each. AVIF supports transparency just like PNG but at a fraction of the file size, often 80% smaller or more.
- Often 80% smaller than PNG in lossy mode, with transparency kept
- Supported by Chrome, Firefox, Safari 16+, and Edge
- Both lossy and lossless compression modes available
- Batch convert entire asset directories at once
- All processing happens locally on your Mac, files never leave your device
PNG vs AVIF file sizes
| File type | PNG | AVIF | Saved |
|---|---|---|---|
| Logo with transparency (800×200) | 480 KB | 65 KB | 86% smaller |
| Product cutout (2000×2000) | 3.2 MB | 420 KB | 87% smaller |
| UI icon set (transparent) | 95 KB | 18 KB | 81% smaller |
| Illustration with alpha (1920×1080) | 1.8 MB | 280 KB | 84% smaller |
When to convert PNG to AVIF
E-commerce product images with transparent backgrounds
Product cutout images in PNG can be 2-5MB each. Converting to AVIF reduces them to 200-500KB with the transparency kept.
Logo and brand asset optimization
Logos with transparency are typically PNG. Converting to AVIF takes a 480KB logo down to 65KB, on every page that shows it.
UI component and icon optimization
Web apps and SaaS products with many UI assets in PNG can convert them in bulk: a 95KB icon set drops to 18KB as AVIF.
Illustration and infographic delivery
A 1920×1080 illustration with alpha drops from 1.8MB to 280KB as AVIF, with its gradients and edges intact.

Defined by ISO/IEC 15948 / W3C Recommendation. Specification
AVIF
AV1 Image File Format
Next-generation image format based on the royalty-free AV1 video codec developed by the Alliance for Open Media (AOMedia). Netflix's 2020 research showed AVIF achieves 50% better compression than JPEG at equivalent perceptual quality.

How do I convert PNG to AVIF on Mac?
Open Picmal, drag your PNG files into the window, select AVIF as the output format, adjust quality settings, and click Convert.
Does AVIF support transparency like PNG?
Yes. AVIF fully supports alpha channel transparency, just like PNG. Your logos, product cutouts, and UI elements with transparent backgrounds convert perfectly.
How much smaller are AVIF files compared to PNG?
In lossy mode, often 80% or more. In the examples on this page, files shrink 81-87%: a 480KB logo becomes 65KB as AVIF. Lossless mode saves much less.
Should I use AVIF or WebP for transparent images?
AVIF produces 20-30% smaller files than WebP at the same quality. Use AVIF for maximum compression and serve WebP as a fallback for browsers that don't support AVIF yet.
Can I use lossless AVIF compression?
Yes. Picmal supports lossless AVIF encoding for pixel-perfect output. Lossless files save much less than lossy ones, so use lossy at high quality when size matters most.
