About This Tool
PNG files are often much larger than they need to be, especially for
photos or detailed graphics — and WebP can shrink them dramatically,
sometimes by 50% or more, while still supporting full transparency
just like PNG does. This tool converts your PNG images to WebP
entirely inside your browser: drop them in and conversion starts
immediately, with a quality slider so you can control the
size-versus-sharpness trade-off yourself.
Key Features
Instant Conversion
No upload step and no button to click — conversion starts the
moment you add an image.
Private & Secure
Your files never leave your device — nothing is ever uploaded to a server.
Batch Processing
Convert a handful of images or hundreds at once — there’s no batch limit.
Transparency Preserved
WebP supports full alpha transparency, so logos, icons, and cutouts convert cleanly with no white or black backgrounds added.
Works Everywhere
Compatible with desktop, tablet, and mobile browsers — no app to install.
Completely Free
No subscriptions, registrations, sign-ups, or hidden limits.
How It Works

Frequently Asked Questions
Is this tool free to use?
Yes, completely free, with no sign-up and no limit on how many images you convert.
Are my images uploaded to a server?
No. Every image is converted locally in your own browser and never leaves your device.
Will my PNG’s transparency be kept?
Yes — WebP supports full alpha transparency just like PNG, so
logos, icons, and cutout images convert without any background
being added.
Will WebP look worse than my original PNG?
At the default quality setting, the difference is generally
invisible to the eye while the file is significantly smaller. A
live preview shows you the result before you download, so you
can raise the quality slider if you want to be extra safe.
Will WebP images work on my website?
Yes — WebP is supported by all current major browsers (Chrome,
Firefox, Safari, Edge). If you need a fallback for very old
browsers, keep the original PNG alongside the WebP version.
Can I convert multiple PNGs at once?
Yes — drop in as many as you like and each one converts automatically, with no batch limit.
