Does PNG to AVIF keep transparency?

Yes when the PNG has partial or full alpha. We clear the canvas before encoding so transparent pixels are not filled with white.

Why is my AVIF sometimes larger?

Rare for simple logos, more common for tiny icons or already-optimized PNGs. Try a slightly lower quality or keep PNG if the difference is negligible.

Is AVIF lossless like PNG?

This converter uses lossy AVIF with a quality slider. For pixel-perfect masters, keep the PNG; use AVIF for delivery copies.

WebP or AVIF from PNG?

If your stack already prefers AVIF, encode here. If partners only accept WebP, use a WebP-focused tool instead.

About PNG to AVIF conversion

PNG is ideal for logos, UI, and screenshots with sharp edges or alpha. Encoding PNG to AVIF can shrink web assets while preserving transparency when the source has an alpha channel.

Why encode PNG to AVIF

Alpha from transparent PNGs is kept in AVIF output
Often much smaller than PNG for web delivery
Great for sites and CDNs that already ship AVIF
Adjustable quality for photos; still strong for many graphics

When to convert PNG to AVIF

Packaging logos or icons for modern browsers
UI chrome and marketing graphics that currently ship as large PNGs
Design handoff assets you want lighter on production
You need AVIF and must keep a transparent background

PNG wins for lossless editing and universal alpha support. AVIF wins for shipping those same visuals with fewer bytes when the browser stack is ready.

Upload PNG, choose AVIF, download. If the PNG is fully opaque, the AVIF is opaque too. Soft edges and glass-style UI usually keep their transparency.

Typical PNG to AVIF workflows

Replace oversized PNG heroes or sticky logos on marketing sites, convert Figma PNG exports for an AVIF-first image pipeline, or shrink documentation sprites. Spot-check alpha over a checkerboard after download.

PNG vs AVIF for graphics

Keep PNG when editors, print, or older tools need lossless round-trips. Prefer AVIF when the asset is final and your CDN serves format negotiation.

Very flat 1-bit style icons may not shrink dramatically. Photographic PNGs usually benefit more. Encoding can take longer than a PNG save—keep the tab open on large canvases.
