Compression

Lossless keeps exact pixels but produces a larger file.

Before you convert

WebP is not supported by very old browsers and some desktop tools. Lossless output can still be large.

Shrink image weight with WebP compression

WebP is a modern image format that typically produces smaller files than PNG at comparable visual quality. Converting a PNG to WebP is useful for websites and apps where download size affects performance.

Lossy mode discards some detail to reach smaller sizes — 80 to 90 percent quality is usually indistinguishable for photographs and screenshots. Lossless mode keeps every pixel identical to the source, but the saving is smaller.

Useful situations

Reduce the size of screenshots, UI graphics, or artwork served on a website.
Prepare images for platforms that accept WebP but charge against PNG file size limits.
Keep a pixel-identical lossless copy while still using a more efficient container.

How to use PNG to WebP

Select a PNG or existing WebP within the size limit.
Pick a quality level, or switch to Lossless for an exact copy.
Convert, compare file size and visible detail, then download the WebP.

What to expect

Lossy WebP is smaller but permanently discards detail — keep the original PNG if you may need it later.
Lossless WebP preserves every pixel but is larger than a lossy file, sometimes larger than the PNG itself.
Very old browsers and some desktop tools cannot open WebP files.

Frequently asked questions

Will a lossy WebP look worse than the PNG?

At 80–90% quality, differences are rarely visible in typical photos and graphics. Zoomed edges and flat colors are where artifacts appear first — compare before deleting the PNG.

Why is my lossless WebP bigger than the PNG?

Lossless compression cannot invent detail and only repackages what exists. For images that already compressed well as PNG, WebP may offer little gain.

Does converting to WebP keep transparency?

WebP supports alpha transparency in both lossy and lossless modes, so transparent PNG areas are preserved by the encoder.
