Drop a PNG file and get a WEBP back in a second. The conversion runs inside this tab — the file is never uploaded, and you need no account.

WebP is roughly 25–35% smaller than JPG at the same quality and is supported by every current browser.

How it works

  1. Add your PNG files — drag them in or pick them from your device.
  2. The page re-encodes them to WEBP locally, using your own processor.
  3. Download the WEBP result, one file or all of them as a ZIP.

No uploads

Photos and PDFs are processed locally in your browser tab. We physically cannot see your files — nothing is transmitted anywhere.

Load the page, switch on airplane mode — conversion keeps working. Or open the Network tab in DevTools: your files trigger no network requests during processing.

Frequently asked questions

Why won't Windows open the HEIC photos from my iPhone?
HEIC is Apple's default camera format and Windows only reads it with a paid codec installed. Converting to JPG or PNG here removes the problem entirely — the file that comes out opens anywhere, and the conversion happens on your own device.
Does converting PNG to JPG lose the transparent background?
It does, because JPEG has no alpha channel — transparent areas are flattened onto white. If you need to keep transparency, convert to WebP or PNG instead; both support it.
Can I convert a whole folder of images at once?
Yes. Drop in as many files as you like and they are converted as a batch, then offered as a ZIP. Mixed input formats in the same batch are fine.
Is WebP smaller than JPG at the same quality?
Usually, by roughly 25–35% for photographs. Every current browser displays WebP, but some older desktop software still does not, which is why JPG remains the safer choice for anything you are emailing or printing.
