Frequently Asked Questions
Why should I convert PNG to WebP?
WebP delivers 25–35% smaller files than PNG at equivalent visual quality and supports both lossless and lossy compression. Smaller images load faster, improve Core Web Vitals scores, and are favored by Google PageSpeed Insights. All modern browsers — Chrome, Firefox, Safari 14+, and Edge — support WebP natively.
Does converting PNG to WebP affect transparency?
No. WebP supports full alpha-channel transparency, so transparent areas in your PNG are preserved exactly in the output WebP file. Enable "Lossless" mode in the quality settings to guarantee pixel-perfect transparency with zero compression artifacts.
Can I convert multiple PNGs to WebP at once?
Yes. Drop up to 10 PNG files simultaneously, set your quality level once, then toggle "Apply to all" to propagate settings across the batch. Download all outputs in a single ZIP archive with one click.
