Does WebP keep transparency?

Yes, fully. WebP supports real transparency, so soft edges, drop shadows, and anti-aliased text all survive exactly as they were in the PNG. This is the main reason to prefer it over JPG when you are converting a logo or an icon.

How much smaller will the file be?

It depends entirely on the picture, so the tool measures yours rather than promising a figure. Photographs saved as PNG tend to shrink dramatically. Flat graphics with few colors shrink less, because PNG is already good at those. Either way the result row shows the real before and after.

Can everyone open a WebP?

Every current browser can, and has been able to for years: Chrome, Safari, Firefox, and Edge all support it. Outside the browser it is patchier, with some older desktop software and a few email clients still unable to. For the web, it is safe. For a file you are emailing to someone unknown, JPG is the safer bet.

Is WebP lossy or lossless?

It can be either. This tool uses lossy WebP by default and measures each result against your original, keeping a setting that still matches it closely. That is where the large size savings come from. Switch Quality to Manual if you have been handed a specific number to hit.

Are my files uploaded anywhere?

No. The conversion runs inside your browser, so your images are never sent to us or to anyone else. You can check by disconnecting from the internet once the page has loaded: the tool keeps working.

Can I convert several PNG files at once?

Yes. Add as many as you like, or drop a whole folder in. Each file is handled on its own and gets its own WebP to download, so a file that cannot be read does not stop the others.

Does converting remove the photo's location data?

Usually, yes. Writing a new file drops the hidden metadata a camera or phone attaches, including GPS coordinates. That is often useful before sharing a photo publicly, but do not lean on it as a privacy tool. Check the file yourself if it matters.

PNG to WebP Converter: Free, No Upload

How it works

Three steps to a WebP

1
Add your PNG files
Drag them in, paste from your clipboard, or browse your files. A whole folder at once is fine.
2
Check the settings
Quality is matched to your original automatically. Set it by hand instead if you have been given a number to hit.
3
Download
Save your WebP files. Nothing was sent anywhere, so there is nothing to delete afterwards.

Why this one

Why convert PNG to WebP here

Transparency survives intact

This is the conversion where nothing is given up. WebP supports full transparency, so a logo with soft edges arrives with those edges exactly as they were. There is no background color to choose here, because nothing needs filling in.

02
Where PNG is still the right answer
Very old software. Some email clients, a few desktop applications, and the occasional corporate CMS still cannot open a WebP. Every browser released in the last several years can, so for anything going on a website this is safe. For a file that has to open in whatever a colleague has installed, keep the PNG.
03
No limits, no queue
Convert as many PNG files as you like, at any size your browser can handle. There is no server to wait for and nothing for us to ration.
04
A whole folder at once
Drop in as many PNG files as you like. Each one is converted separately and gets its own result, so one awkward file cannot spoil the rest of the batch.
05
It shows you the real numbers
Every file reports what it weighed before and after, and which way it moved. Where another format would have come out meaningfully smaller than WebP, that is offered next to the file instead of being quietly withheld.

Who it's for

When you'd use it

Someone speeding up a website
Page weight is mostly images. Swapping PNGs for WebP is usually the largest single improvement available, and it needs no code changes beyond the file names.
Someone with a folder of them
A batch that all needs to be WebP before it goes anywhere, dropped in together rather than converted one at a time.
Someone on a work laptop
Software installs are blocked and the files are not theirs to upload to a stranger's server. A browser tab is the only tool available, and it is enough.
