Why convert PNG to WEBP?

WebP files are roughly 30% smaller than PNG at the same visible quality, which makes pages load faster without changing how they look.

How to convert PNG to WEBP

  1. Choose your PNG file. Drop it on the box above, or tap to browse. You can pick several files at once.
  2. Confirm the target is .webp. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
  3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .png file?

PNG is lossless: it stores every pixel exactly as it was, and supports a transparent background. It is the right format for screenshots, logos, diagrams, icons and anything with sharp edges or text. Photographs come out noticeably larger than they would as JPG.

What is a .webp file?

WebP is Google's web image format: roughly 30% smaller than JPG at the same visible quality, with support for transparency and animation. Every current browser displays it, but a great many desktop applications still cannot open one, which is why converting WebP to PNG or JPG is such a common need.

What to expect from this conversion

The image is decoded and re-encoded, so keep the quality slider at 85% or above — at that setting the difference is invisible to the eye. Transparency is flattened onto white for formats that cannot store it, such as JPG.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your PNG file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.

Questions about PNG to WEBP

Is this PNG to WEBP converter free?
Yes, completely. There is no account, no daily limit, no watermark and no premium tier.
Is my PNG file uploaded to a server?
No. The conversion runs inside your own browser using your device's processor. The file is read from your disk, converted in memory and saved back to your disk — nothing is transmitted, so there is nothing for anyone to store.
Can I convert PNG to WEBP online without downloading software?
Yes. This is an online PNG to WEBP converter that runs in your browser, so there is nothing to install and no app to trust with your files. It works the same on a phone.
Does converting PNG to WEBP lose quality?
The image is decoded and re-encoded, so keep the quality slider at 85% or above — at that setting the difference is invisible to the eye. Transparency is flattened onto white for formats that cannot store it, such as JPG.
Can I batch convert several PNG files to WEBP at once?
Yes. Select as many files as you like and they are converted one after another in a single tap, with a download for each and a zip of all of them.
Should I keep the original PNG file?
Yes — keep it, converting never touches it. The reason to make a copy in another format is that PNG keeps every pixel exactly, which makes photographs several times larger than they need to be.
