Convert PNG to WebP online

PNG files are lossless and often huge. WebP keeps the transparency you rely on while cutting the file size by 50–80%. Convert one PNG for free right now, or upgrade to PRO to batch-convert your whole assets folder.

Why convert PNG to WebP?

Up to 80% smaller than PNG for the same visual result, especially on screenshots and UI mockups.

Transparency preserved. WebP has a full 8-bit alpha channel, so logos, icons and cut-outs keep their transparent background.

Faster pages, better rankings. Lighter images directly improve Largest Contentful Paint (LCP), a Core Web Vital that Google uses in ranking.

Universal support. Every modern browser, including Safari on iOS 14+, displays WebP natively.

How to convert PNG to WebP

Step 1

Select your PNG files

Click the drop zone or drag and drop your PNG images. Files stay on your device; nothing is uploaded.

Step 2

Choose quality and size

Move the quality slider (80% is ideal for most images) and set a maximum width to downscale oversized images.

Step 3

Convert to WebP

Press "Convert to WebP". Your browser encodes each PNG to WebP in a fraction of a second.

Step 4

Download

Download each WebP file, or grab the whole batch as a ZIP with PRO.

When should you convert PNG to WebP?

PNG is the right format while you are designing: it is lossless and every export is pixel-perfect. It is the wrong format for publishing. A 1600 px screenshot exported as PNG easily weighs 1–2 MB; the same image as WebP at 90% quality typically lands between 150 and 300 KB with no visible difference. If a PNG is going on a web page, in an email or into an app bundle, convert it.

PNG with transparency

Transparent PNGs (PNG-32) are the most common reason people avoid JPEG, because JPEG has no alpha channel. WebP solves this: it supports lossy compression and transparency in the same file. Product photos on transparent backgrounds, logos and UI overlays all convert cleanly.

Recommended quality for PNG sources

Because PNG originals are typically graphics rather than photographs, choose a slightly higher quality than you would for JPEG: 85–92% keeps text edges crisp and flat colours banding-free. For photographic PNGs (for example exports from a camera app), 80% is plenty.

PNG to WebP: questions

No. WebP supports an alpha channel, and this converter preserves transparency from your PNG. Transparent areas remain transparent in the resulting WebP file.

This tool uses lossy WebP encoding with a quality slider, which gives the biggest savings. At 90–95% the result is visually identical to the PNG for virtually all uses. If you need mathematically lossless output, keep the PNG original for editing and use WebP for publishing.

Typically 50–80% smaller. Screenshots and flat graphics see the biggest gains; photographic PNGs shrink by 70–90% because PNG is a very inefficient format for photos.

Yes. The converter runs in any modern mobile browser (Safari on iOS 14+, Chrome on Android). Select images from your photo library and download the WebP results.
