PNG to WebP Converter
PNG files are loved for their lossless compression and transparency support, but they are often huge - screenshots and UI graphics can easily reach several megabytes. Converting PNG to WebP shrinks those files dramatically: WebP lossless is up to 26% smaller than PNG for the same pixels, and if you can accept a tiny, invisible quality trade-off, lossy WebP with alpha is smaller still.

Supports JPG, PNG, GIF, SVG, ICO, BMP, AVIF, WebP
PixConvert converts PNG to WebP entirely in your browser. There is no upload step, no queue, and no file size sign-up wall - drag in a single logo or a hundred screenshots and get optimized WebP files in seconds. Transparency is preserved automatically, so rounded corners, shadows, and icon alpha channels survive the conversion intact.
Why convert PNG to WebP?
Up to 26% smaller, losslessly
WebP lossless beats PNG on virtually every image. If you ship lots of screenshots, diagrams, or UI assets, the savings add up fast across a documentation site or app bundle.
Transparency preserved
WebP supports the same alpha channel as PNG. Icons, logos, and cut-outs keep their transparent backgrounds after conversion.
Faster sites and apps
Replacing PNG assets with WebP reduces page weight and app bundle size with zero visual change - one of the cheapest performance optimizations available.
Lossy option for maximum savings
Need even smaller files? Switch to lossy mode with alpha support to shrink PNG-style graphics by 60-90% while keeping edges clean.
How to convert PNG to WebP
- 1
Upload your PNG files
Drag and drop one or more PNG images, or click the upload area to select files. Batch conversion of entire sets is supported.
- 2
Confirm WebP output and mode
WebP is preselected. Choose lossless mode to keep the image pixel-identical, or lossy mode with a high quality value for the smallest possible file.
- 3
Check transparency in the preview
The comparison slider shows the original next to the converted result, so you can confirm alpha edges and fine details look right.

Download your WebP files
Save individual files or get everything at once as a ZIP archive. All processing happened locally in your browser.
Frequently asked questions
Does PNG to WebP conversion keep transparency?
Yes. WebP fully supports the alpha channel, so transparent backgrounds in logos, icons, and cut-out graphics are preserved exactly. Lossless mode is bit-exact; lossy mode keeps clean alpha edges with slightly higher compression.
Is WebP really smaller than PNG?
Google's benchmarks put WebP lossless at about 26% smaller than PNG on average. For lossy conversion of screenshots and interface graphics the reduction is often far larger - frequently 60-90%.
Should I use lossless or lossy mode?
Use lossless when the PNG contains text, thin lines, or exact colors that must not shift - for example technical diagrams. Use lossy (quality 80-90) for photographs or soft-edged graphics where small compression artifacts are invisible.
Will WebP images work in Photoshop and other editors?
Recent versions of Photoshop, GIMP, Figma, and all major design tools open WebP natively. Very old software may need a plugin, in which case keep the original PNG as your editing master.
Is there a file limit or upload wait?
There is no server and therefore no upload wait at all - conversion speed depends only on your device. Batch-convert hundreds of PNGs without creating an account.
