PNG to WebP Converter
Turn a PNG into a smaller WebP file without losing its transparent background. Everything runs right in your browser, so your image never gets uploaded.
Everything runs in your browser — your image is never uploaded, sent to a server, or stored. Nothing leaves your device.
How it works
Choose your PNG and the tool re-encodes it as WebP using a quality slider (default 90%). Higher quality keeps more detail but makes a bigger file; lower quality shrinks it further. Transparency carries over untouched, and the width and height stay exactly the same — only the format changes. Your download keeps the original file name, just with a .webp ending.
When to use it
Use this when you want a lighter file for the web — logos, icons, or graphics with transparency — without giving up the see-through background PNG gives you. It's a solid, modern swap for PNG almost anywhere a browser will display the image.
Frequently asked questions
Does WebP keep the transparent parts of my PNG?
Yes. Unlike JPG, WebP fully supports transparency, so any see-through areas in your PNG stay see-through after converting.
Will the file be smaller than my PNG?
Usually, yes. WebP typically produces smaller files than PNG at similar visual quality, which is why it's a popular replacement for PNG on the web.
Is my image uploaded anywhere?
No. The conversion happens entirely in your browser using a canvas element. Your file never leaves your device.
