Convert PNG to WebP
Convert PNG to WebP instantly in your browser. Smaller files for the web, no uploads.
PNG is great for graphics but heavy for photos and detailed images, which slows down the pages that use it. WebP offers much smaller files with excellent quality and, unlike JPG, it can preserve transparency — making it a strong replacement for PNG on the web. This converter processes your PNG to WebP locally in the browser, so your files never touch a server. Convert a single PNG and download the WebP instantly, or use batch mode to convert up to five images at once into a ZIP. WebP supports both lossy and lossless modes and an alpha channel, so transparent PNGs convert cleanly without a background fill. The result is a smaller, modern file that keeps graphics sharp and pages fast. It is free, private, with no watermark and no file-count limit.

Frequently asked questions
Why convert PNG to WebP?+
WebP produces much smaller files than PNG while keeping quality high, and it still supports transparency. That makes it ideal for web graphics where PNG would be unnecessarily heavy.
Does WebP keep PNG transparency?+
Yes. WebP supports an alpha channel, so transparent areas in your PNG are preserved during conversion — no background fill is added.
How much smaller is WebP than PNG?+
It varies by image, but PNGs often shrink substantially when converted to WebP, especially photographic or detailed graphics. Simple flat graphics save less.
Are my PNG files uploaded?+
No. Conversion runs entirely in your browser using the Canvas API, so your files stay on your device.
Can I convert multiple PNGs to WebP at once?+
Yes. Batch mode converts up to five PNGs to WebP and downloads them together as a ZIP.
