# Converters

Why convert PNG to WebP?

PNG is lossless, which makes it great for editing but heavy on the web — a single screenshot or product cut-out can easily weigh a few megabytes. WebP was built by Google specifically for websites: it supports the same alpha transparency as PNG while producing far smaller files.

This PNG to WebP converter encodes with libwebp compiled to WebAssembly, directly on your device. Your files are never uploaded, so it is safe for client work, unreleased designs and private screenshots.

  • Transparency preserved

    Logos, icons and cut-outs keep their transparent background — no white boxes.

  • Batch convert

    Convert 5 or 500 PNGs at once. There is no per-batch cap and no daily limit.

  • Better Core Web Vitals

    Lighter images load faster, which improves Largest Contentful Paint and page speed scores.

# FAQ

PNG to WebP: common questions

Does converting PNG to WebP lose quality?

WebP can be lossy or lossless. At the default setting the difference is invisible for photos and screenshots; for pixel-perfect graphics, raise the Quality slider toward 100.

Will my transparent PNG stay transparent?

Yes. WebP supports a full alpha channel, so transparent and semi-transparent areas are preserved exactly as in the original PNG.

Do all browsers support WebP?

Every current version of Chrome, Edge, Firefox, Safari and Opera supports WebP, on both desktop and mobile.

Can I convert PNG to WebP for WordPress?

Yes — convert here and upload the .webp files, which WordPress has supported since version 5.8. For automatic conversion on upload, use our free WordPress plugin.
