Frequently Asked Questions

Why convert PNG to AVIF?

PNG (Portable Network Graphics) uses lossless encoding and is best for graphics with sharp edges, text overlays, screenshots, and images requiring transparent backgrounds. AVIF (AV1 Image File Format) uses lossy or lossless encoding and excels at next-gen web images — royalty-free format with better compression than WebP and JPEG. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.

How much smaller than PNG?

Typically 30–50% smaller than PNG with transparency intact — biggest wins on photos.

Photos or graphics for AVIF?

Both — AVIF handles gradients and flat color better than PNG.

When to keep PNG?

Editing masters and pixel-exact screenshots stay PNG for lossless re-edits.

Is my work uploaded anywhere when using PNG to AVIF?

No — conversion runs locally in your browser; unlimited saves on local tools.
