## PNG is a master; AVIF is a delivery format
Exporting PNG from Figma or Photoshop is correct for source control. Serving that PNG to every visitor is often not. Photographic PNGs are huge because lossless compression cannot discard grain. AVIF can. On a product cutout, it is common to see 70–90% size cuts at a quality that still looks like the PNG on a phone. That is the reason this converter exists: take the graphic you already have and make a next-gen derivative for the web.
Keep the PNG. AVIF is harder to edit in some apps, slower to encode, and still missing from email and a long tail of WebViews. The pipeline is PNG (master) → AVIF (primary web) + WebP (fallback). ToolPin can also do PNG to WebP if you are not ready for AVIF yet.
## Alpha, type, and when AVIF misbehaves
AVIF supports alpha. A transparent PNG can become a transparent AVIF. Test it. Some older Safari versions had AVIF gaps; current versions are fine. Soft hair and smoke are the stress test—check for ringing or a dirty matte.
Type and UI chrome are the other stress test. AVIF’s blockiness can nibble at small text more than PNG does. If the PNG is a screenshot of a dashboard, you may prefer compressed PNG or WebP lossless. AVIF’s wins are biggest on continuous-tone images: photos, paintings, 3D renders, and rich illustrations. A three-color logo might be smaller as SVG or a tiny PNG8.
You cannot recover what a lossy AVIF drops. Do not replace the only copy of a logo with AVIF. Treat this like exporting a JPEG: a publish step.
## Encode cost and browser support
Encoding AVIF in a tab is heavy. Phones may take a while or fail. Use desktop for 4K PNGs. Decoding AVIF for visitors is widely available in current Chrome, Firefox, and Safari, but not in many mail clients or in-app browsers. Always provide a fallback.
ToolPin runs locally. Brand PNGs are not uploaded to toolpin.online. 250 MB limit; memory and time will bite first. No watermark, no account. Animated PNG (APNG) becomes a still AVIF.
Color: 16-bit or wide-gamut PNG will be reduced to what the canvas can draw, typically 8-bit sRGB. That matches the web. It does not match a print master—keep TIFF or PDF for print.
## How to use the file
In HTML,
with AVIF then WebP then PNG/JPEG. In Next.js or similar, let the image pipeline negotiate if you prefer, but a pre-encoded AVIF still helps when you control the asset. Measure LCP. If savings are tiny, skip AVIF for that asset. If savings are huge, convert the rest of the hero set. Never send AVIF to a print vendor.
