Common questions

Why convert PNG to WEBP?

WEBP is Google's modern image format designed for the web. It typically produces files 25–35% smaller than PNG while preserving transparency and visual quality — meaning faster page loads, lower hosting costs, and better Core Web Vitals scores. Every major browser has supported WEBP since 2020.

Is transparency preserved?

Yes. WEBP supports full 8-bit alpha-channel transparency, exactly like PNG. Logos, icons, and images with transparent backgrounds will keep their transparency through the conversion.

Will I lose any image quality?

By default we use lossless WEBP encoding when the source PNG is small enough, which preserves every pixel exactly. For larger images we use high-quality lossy WEBP (~90% quality) — visually identical to the original for almost any use case. If you need pixel-perfect preservation, use the API with the lossless flag.

Is there a file size limit?

Free users can convert PNG files up to 25 MB without an account, or up to 10 conversions per day with a free account. Pro users get 500 MB per file and 3,000 credits a month. Business users get up to 5 GB.
