Does WebP support transparency like PNG?

Yes — WebP has full alpha channel support in both lossy and lossless modes. This converter preserves transparency exactly: a transparent logo stays transparent. That's the key advantage over PNG-to-JPG conversion, which flattens transparency to white.

How much smaller is WebP than PNG?

At quality 90 (lossy), expect 50-80% reduction for screenshots and UI graphics — a 3 MB screenshot commonly becomes 400-900 KB. In lossless mode, WebP still beats PNG by roughly 25% thanks to better compression algorithms. The lossy mode is the right default for web delivery; lossless for archival masters.

Will screenshot text stay sharp in WebP?

Yes — WebP's compression handles sharp edges and text much better than JPEG, which produces visible ringing around letters. At quality 90, UI text in WebP screenshots remains crisp and readable. This is precisely why WebP displaced JPEG for screenshot-heavy documentation.

Is WebP supported everywhere?

All browsers released since 2020: Chrome, Edge, Firefox, Safari 14+, and mobile equivalents — effectively 97%+ of web traffic. Older enterprise environments may need PNG fallbacks; the HTML picture element lets you serve WebP with a PNG fallback cleanly.

Does converting PNG to WebP lose quality?

In lossy mode, technically yes — but at quality 90 it's visually imperceptible for screenshots and graphics. For pixel-exact needs (further editing, archival), keep your PNG master and use WebP only for web delivery. You can also convert back anytime with the WebP to PNG converter.

PNG or WebP — which should I use?

PNG for editing masters, files that will be re-saved repeatedly, and compatibility with older tooling. WebP for anything delivered over the web — it's strictly better for that job: smaller, transparency-capable, sharp-edge-friendly. The professional pattern: keep PNG sources in version control, ship WebP to users.

Can I batch convert a whole folder?

Convert files one at a time here — drag, convert, download, repeat. There's no cap on how many you process since everything runs locally on your machine.

What is this

PNG is the web's lossless workhorse — perfect for screenshots, logos, and transparent graphics, but heavy: a UI screenshot can easily run several MB. WebP offers two paths for PNG replacement: lossy mode (quality 90 here) cuts file size by 50-80% with edges that stay visually sharp, and lossless mode typically still beats PNG by ~25%. Either way, transparency in the source PNG is preserved in the WebP output — unlike JPG conversion, which flattens it. Every browser since 2020 renders WebP natively, which is why the format has become the default delivery format for sites like YouTube and eBay. This converter re-encodes your PNG at quality 90 via the browser's Canvas API, keeping dimensions untouched and the alpha channel intact — locally, with no upload. Use it to slim down design assets, app screenshots, and transparent logos for web delivery while keeping pixel-exact PNG masters in your source control.
