WebP to PNG

Convert WebP and AVIF to PNG or JPG in your browser. Files never upload. Free, batch ZIP, no account.

Drop WebP or AVIF files here

.webp / .avif / .png / .jpg · multiple OK

or drag & drop · paste Ctrl/⌘V

Private: Conversion stays in your browser — files never upload.

How to verify no upload
  1. Open DevTools (F12 or ⌥⌘I) → Network tab.
  2. Drop a WebP/AVIF and wait until the output is ready.
  3. Confirm there is no image POST/upload — only the page and scripts load.

“Try sample WebP” may fetch a public demo from this site — that is not your file upload.

FAQ

Do my files leave my device?

No. Conversion runs in your browser. We only serve the page — your images are never uploaded for conversion.

What formats can I convert?

WebP, AVIF, PNG, and JPG/JPEG as inputs. Output PNG, JPG, or WebP. HEIC is handled by HeicLocal (linked below).

Is EXIF / GPS kept?

No. We re-encode in the browser and do not copy EXIF/GPS — on purpose, for privacy.

Is WebpKit free?

Yes. Free forever — no account, no paid plans, no ads.
