About this conversion
Why convert PNG to WebP?
Converting an image changes the way its pixels are stored, not the picture itself. Your PNG file keeps its exact dimensions and detail, and the result becomes a WebP file that other apps and websites can use straight away.
Everything happens on your device: the image is decoded, re-encoded, and handed back to you without touching a server. Compare the file sizes above and keep the version that suits your project.

PNG
PNG is a lossless format that keeps every pixel intact and supports transparent backgrounds. Perfect for logos, screenshots, and graphics with sharp edges.
WebP
WebP is a modern web format that produces much smaller files than JPG or PNG while keeping quality, transparency, and even animation support.
Why use it
Fast, free, and private
A converter that does one job properly — no installs, no queues, no limits.
Instant conversion
Drop a file and get the result in a second. The image is processed on your device, so there is no upload wait.
Quality in your hands
Pick the compression level yourself. Keep maximum detail for print, or squeeze the file down for the web.
Nothing is uploaded
Your image never leaves the browser. No servers, no storage, no copy of your file anywhere.
Six formats covered
JPG, PNG, WebP, BMP, TIFF, and GIF are all supported, so you can move images between any of them.
How it works
Three simple steps
No software to install and no account to create — just upload, convert, and download.
Upload
Drop your PNG file onto the box, click to browse, or paste an image straight from the clipboard.
Convert
Adjust the quality slider if you want, then press Convert. The file is processed instantly on your device.
Download
Save the finished WebP file and drop in another image whenever you are ready — there is no limit.
FAQ
Frequently asked questions
Is this PNG to WebP converter free?
Yes — free to use, with no watermark, no file limit, and no account required. Convert as many images as you like.
Do my images get uploaded to a server?
No. Conversion runs entirely inside your browser, so the file never leaves your device. You can disconnect from the internet and it still works.
Will I lose quality when converting PNG to WebP?
Only as much as you decide. WebP is a compressed format, so the quality slider controls the trade-off — set it near maximum and the difference is invisible, while the file stays small.
What is the difference between PNG and WebP?
They store image data differently, which affects file size, quality, transparency, and which apps accept them. Use the converter whenever you need WebP but only have PNG — for example to publish a photo online or open a file in another program.
Can I convert more than one image?
Yes. Finish one image and start the next right away — there is no batch limit and no queue. Every file is converted the same way, one after another.
Which browsers are supported?
Any current browser: Chrome, Edge, Firefox, and Safari on desktop and mobile all work. Nothing extra needs to be installed.

About the PNG to WebP converter
When you should convert PNG to WebP
Websites, apps, and stores often ask for a specific format. If you have a PNG file and something needs WebP, uploading it to another service is unnecessary — this page converts it locally in a couple of seconds.
Quality, transparency, and file size
Format changes affect size more than they affect the picture. Converting to a compressed format shrinks the file, while a lossless target keeps everything exactly as it was. Check the before and after sizes after each conversion to find the balance your project needs.
Private by design
Because conversion happens in the browser, no image is ever sent to us. That makes this tool a sensible choice for photos, product shots, scans, and client work you would rather not share.
