Quality
80%
Lower quality means a smaller file. WebP keeps transparency, so any transparent areas in a PNG are preserved.
Files are converted in your browser and never uploaded. Metadata is removed automatically.

01

Add your PNGs

Drop one file or a folder's worth onto the panel. They are read straight off your disk — there is no upload bar because there is no upload.

02

Set the quality

80 suits most images. Screenshots and flat graphics hold up well much lower; photographs saved as PNG benefit from staying higher.

03

Check the saving, then download

Each file shows its before and after size. Take one, or the whole batch as a ZIP.

Why this one

Built against the ways these tools disappoint.

We ran the same files through the popular alternatives first. These are the gaps we found, and what this tool does instead.

01

Many converters flatten transparency onto a white background without warning.

WebP keeps the alpha channel, so transparent areas stay transparent.

test: convert a logo with a transparent background
02

Converters upload your images to a server to do the work.

Everything runs in your browser — no queue, no file-size cap, nothing on our side to delete.

test: turn your wifi off after the page loads and convert anyway
03

You do not see what the compression cost until after you download.

Each file lists its original and converted size side by side before you save.

test: drop one screenshot and read the two numbers
The detail

How this actually works.

PNG is the right format for logos, icons and screenshots — but it’s heavy, and on a website that weight slows pages down. WebP fixes that: it keeps the transparency PNG is prized for while cutting the file size dramatically — 25–50% for flat graphics, and 60–90% for photographs that were saved as PNG by mistake. Every current browser displays WebP, so for anything web-bound it’s a straight upgrade.

The part cheaper converters get wrong is transparency. Many flatten the alpha channel onto a white background without telling you, which ruins a logo the moment it sits on a coloured page. This keeps the alpha intact, so transparent stays transparent. You pick the quality, and each file shows its original and converted size so the saving is visible before you download.

Everything runs in your browser — your images are converted on your own device and never uploaded. Need a different route? JPG to WebP and AVIF to WebP use the same engine, and Compress Image targets an exact file size when you have a hard limit. The format field guide explains when to keep PNG and when WebP wins.

FAQ

The questions people actually type in.

Are my images uploaded to a server?

No. The conversion runs entirely inside your browser. You can turn your wifi off once the page has loaded and convert anyway.

Does converting PNG to WebP keep transparency?

Yes. WebP supports an alpha channel, so transparent backgrounds survive the conversion intact.

How much smaller is WebP than PNG?

For logos and flat graphics, usually 25–50% smaller. For photographs that were saved as PNG the saving is far larger, often 60–90%, because PNG is a poor fit for photographic detail in the first place.

Is WebP lossless like PNG?

The default here is lossy, which is why the files get so much smaller. Set the quality to 100 for the closest match to the original if you need it.

Can I convert several PNGs at once?

Yes, with no file-count limit. Download them individually or as a single ZIP.

Should I use PNG or WebP for a logo on my website?

WebP, in almost every case — it keeps the transparency a logo needs and is far smaller, so the page loads faster. Keep the PNG original for anything going into print or older desktop software that can't read WebP.
