About PNG to WebP
PNG is excellent for preserving transparency and sharp edges, but its lossless compression produces large files. WebP gives you a smaller file at the same visual quality, and it also supports transparency. That combination makes WebP the better choice for almost any image that will be served on a website or inside an app.
This tool converts PNG files to WebP directly in your browser. If your source PNG has a transparent background, the WebP output preserves it. Your images never leave your device — the conversion runs locally using the Canvas API. No upload queue, no server processing, no privacy risk.
At the default 90% quality, the difference from the original PNG is invisible to the naked eye while the file size drops significantly. Every modern browser supports WebP natively — no plugin needed, no watermark, no limit.
Frequently Asked Questions
Why convert PNG to WebP?
WebP produces smaller files than PNG at the same visual quality and supports transparency. It is the better choice for images that will be used on websites or in apps.
Does WebP support transparency?
Yes. If your source PNG has a transparent background, the converted WebP will preserve it. This makes WebP a direct replacement for PNG in many web workflows.
Will the image quality be preserved?
Resolution and color accuracy are fully preserved. WebP uses a more efficient lossy compression than PNG, so you get smaller files at the same visual quality. At the default 90% setting, the difference from the original is invisible. You can adjust the slider to find your preferred balance between size and fidelity.
Is there a file size limit?
There is no hard limit. Since processing runs locally in your browser, the practical limit depends on your device's memory. Most PNG images convert instantly.
Do I need to sign up or pay?
No. There is no account, no watermark, no subscription, and no "upgrade for HD" trap. Every feature is free and unlimited.
Is my photo data safe?
Yes. All conversions happen entirely in your browser using the Canvas API. Your photos never leave your device — no uploads, no servers, no logging.
