PNG to WebP
Keeps the transparency a JPG would lose, at a fraction of the size. On your device.
More free conversions, where you upload. The Fylane extension does the same work inside any upload form, on its own free share every day.Add to Chrome
How to convert PNG to WebP
- Drop the PNG.
- Pick a quality.
- Press Convert and download the WebP.
What happens to your file
WebP keeps the alpha channel, so logos and cut-outs stay transparent, and its lossy mode makes flat graphics far smaller than PNG can.
At the highest quality setting fine gradients are indistinguishable; at lower settings, edges in flat art can soften slightly. Compare on the page before you download.
Questions
Lossless WebP?
This page uses the lossy mode with your quality; at 92 the difference from lossless is not visible in practice. The API offers both.
Do it once, not on every form
A form that wants a square JPEG under 240 KB says so on the page. The Fylane extension reads that, fits your photo to it, and puts it in the field — without you working out what 240 KB looks like.
And it keeps the result. The next application that asks for a résumé, a cover letter and a photo fills all three from one tap, each one refitted to what that site accepts.
Your files stay in the browser, encrypted, on your machine. Nothing is uploaded to keep them and nothing is sent anywhere to fill a form.
