About this tool

While PNG is great for lossless graphics and transparent layers, its file sizes can be extremely large—often leading to slow websites and bloated apps. WebP is a modern image format developed to solve this, offering identical transparency support and visual sharpness at a fraction of the file footprint. Our PNG to WebP Converter recompiles your graphics directly inside your browser window. Since the conversion uses local canvas operations, your proprietary design mockups, proprietary charts, or screenshots are never transmitted to an external server.

Common scenarios

Speeding up websites

Convert transparent PNG icons and website banners to WebP to reduce site weight and improve Core Web Vitals.

Optimizing mobile assets

Compress design layouts and app UI screenshots before packing them into mobile app bundles to save download size.

Sharing mockups

Convert raw interface designs to compact WebP files to share them instantly over Slack, Discord, or email.

FAQ

Why use WebP?

WebP often gives smaller files than PNG while preserving good visual quality.

Does transparency work?

WebP supports transparency, and the converter should preserve it.

Will I lose image quality?

WebP uses highly advanced compression. By adjusting the quality setting (e.g. to 80% or 90%), you can shave off up to 70% of the file size with virtually zero visible difference.

Is WebP supported by all browsers?

Yes. Modern versions of Safari, Chrome, Firefox, Edge, and mobile browsers provide full native support for WebP images.

Are my design files uploaded?

No. The entire conversion runs in your browser's local sandbox, keeping all your graphic assets, logos, and drafts completely private.

Can I convert multiple PNGs at once?

Yes. You can select multiple PNG files to convert and download WebP copies in batches.
