Convert PNG to WEBP Free Online

WebP is the modern successor to PNG: it keeps transparency and offers a lossless mode, but produces noticeably smaller files. Converting PNG to WebP typically saves around 26% in lossless mode and far more in lossy mode, making it ideal for logos, icons, and graphics on the web without sacrificing the alpha channel.

Why WebP beats PNG for the web

PNG is lossless and supports transparency, which makes its files large. WebP gives you the same transparency support plus a choice of lossless or lossy compression. Lossless WebP is about a quarter smaller than the equivalent PNG, and lossy WebP can be dramatically smaller while still looking clean—perfect for site graphics where every kilobyte counts.

How to convert PNG to WebP

Upload your PNGs, keep the format on WebP, and convert. For graphics with text or sharp edges, use a higher quality (90+) or lossless mode to keep them crisp; for decorative images you can drop to 80 for a much smaller file. Batch-convert and download everything as a ZIP.

Transparency is preserved

Unlike JPG, WebP fully supports an alpha channel, so transparent PNGs convert cleanly with their transparency intact. That makes WebP the best choice when you want PNG-style transparency but smaller downloads—logos overlaid on colored backgrounds, UI icons, and product cut-outs all work well.

About WebP

WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. WebP typically achieves significantly smaller file sizes compared to PNGs and JPEGs.

Frequently Asked Questions

Does WebP keep PNG transparency?

Yes. WebP supports a full alpha channel, so transparent areas in your PNG are preserved exactly after conversion.

Is WebP lossless like PNG?

WebP offers both lossless and lossy modes. Lossless WebP preserves every pixel like PNG while being roughly 26% smaller on average.

How much smaller will my files be?

Expect about 26% savings in lossless mode, and much larger savings in lossy mode depending on the quality you choose.

Is WebP supported everywhere?

Yes, all modern browsers support WebP. For very old software that does not, convert to PNG or JPG instead.
