Convert PNG to WebP
Converting PNG to WebP is the rare move that loses nothing you can see: WebP keeps the full transparency channel and still produces a clearly smaller file. For websites, that means faster pages with the same visual result.
Upload your PNG files above, keep the output as WebP and download the results. The quality slider applies here; the default 85 is where photos and graphics shrink clearly with no visible change.
Why is WebP smaller than PNG?
PNG is lossless by law: it must store every pixel exactly. WebP is allowed to simplify detail the eye struggles to catch, the same trick JPG uses, while still keeping transparency that JPG cannot carry.
The result is the best of both worlds for most web graphics: the logo keeps its transparent background, the photo keeps its look, and the file gets smaller either way.
How to convert PNG to WebP
- Upload your PNG files; up to 20 files per request, each up to 100 MB.
- Keep the output format as WebP.
- Set the quality; 85 is balanced for most images.
- Start the conversion and download the WebP files one by one or as a ZIP.
Does transparency survive?
Yes. WebP carries a full alpha channel, so transparent and semi-transparent areas in your PNG come across exactly. This is the key difference from converting to JPG, where transparency has to be filled with a solid color.
If you are moving a site's icons or logos from PNG, WebP is usually the right target: same transparency, smaller file, and every modern browser displays it.
Where can WebP be used?
All current browsers display WebP, and modern image editors open it. The weak spots are older programs and some office tools; if the image has to open in software from a decade ago, PNG or JPG remains the safer choice.
For anything shown on a website you control, WebP is the practical default: faster pages at the same visible quality, with no compatibility risk that matters today.
A note on measurement: if you are converting for a website, the gain shows up in your page-speed numbers quickly. Lighter images mean a faster first paint, and faster pages keep visitors around longer. It is one of the few optimizations that costs nothing once the files have been converted. Combined with sensible image dimensions, it is usually the single biggest easy win on an image-heavy page. Your visitors never notice the change; they only notice that the page feels quick. That feeling is what brings them back tomorrow.
Does PNG to WebP keep the transparent background?
Yes. WebP supports full transparency, so transparent and semi-transparent areas carry over exactly.
How much smaller is WebP than PNG?
It depends on the image; photos and detailed graphics shrink the most, often by half or more at the default quality. The result card shows the exact saving for each file.
Do all browsers open WebP?
All current browsers do. Very old programs and some office tools may not; for those, PNG or JPG is safer.
