Convert PNG to WebP Online

How to convert PNG to WEBP

1. 1

   Upload PNG files

   Add one or more PNG images to the queue. Transparency is read from the source and kept where the encoder supports it.

2. 2

   Set WebP quality

   Open Options and choose a quality level. Start high for text and graphics, and reduce it for large decorative photos.

3. 3

   Convert and download

   Run the queue and download the WebP files individually or as a ZIP.

Portable Network Graphics vs WebP image

Why convert PNG to WEBP?

• Reduce image weight on modern websites without giving up alpha transparency.
• Serve faster product images and illustrations to browsers that support WebP.
• Keep a transparent source in a format designed for the web.
• Create a smaller delivery copy while preserving the original PNG master.

Will quality change?

WebP can be lossy or lossless, but this tool uses a quality setting that usually produces lossy output. Transparent areas are preserved, and most images look close to the PNG at a good quality level. Sharp text and flat graphics can soften at lower settings, and the file may be larger than PNG if you choose near-lossless quality.

Processing and limits

Processing

Browser first, server fallback

Engine

Browser Canvas, with Sharp as the server fallback

Maximum size

Server fallback accepts files up to 100 MB. Browser conversions depend on device memory.

Batch support

Yes, batch conversion is supported.

Quality controls

Adjustable WebP quality. Higher values keep more detail; lower values produce smaller files.

The browser decodes the PNG and asks the canvas to encode WebP locally. If the browser cannot encode WebP, the server uses Sharp. The processed image downloads directly and is not stored as a hosted file.

• Older applications may not open WebP even though modern browsers do.
• Animated PNG is not preserved as an animation in this conversion path.
• Lossy WebP can soften small text and fine line art.

Platform compatibility

WebP is supported in all current major browsers and in many modern image viewers. Windows, macOS, Linux, iOS, and Android support varies by app, so keep the PNG if the file must open in older desktop software.

When not to convert

• Do not use WebP as the only copy when the recipient may open it in an old editor or publishing tool.
• Keep PNG when you need a lossless archive or repeated editing without re-encoding.
• For print production, check whether the printer accepts WebP before replacing the PNG.

Frequently asked questions

Does PNG to WebP keep transparency?

Yes. WebP supports alpha transparency, so transparent parts of the PNG can remain transparent in the output.

Is WebP always smaller than PNG?

Usually for photos and complex images, but not always for tiny icons or flat graphics. Check the output size if storage is the main reason for converting.

What quality setting should I use?

Use a high setting for text, logos, and product images. Lower settings can work for large photographic backgrounds where small artifacts are less visible.

Will all browsers display the WebP?

Current Chrome, Edge, Firefox, and Safari support WebP. Older browsers and some desktop apps may not, so keep a PNG fallback for critical content.

Can I batch convert PNG images?

Yes. Add multiple PNGs, apply one quality setting, and download the converted WebP files together as a ZIP.

Does this tool preserve animation?

This path treats the input as a still image. Animated PNG is not carried into an animated WebP by this converter.
