Convert PNG to WebP

Drop PNGs below to convert them to WebP. Transparency is kept and files are often 60–90% smaller — especially for photos and screenshots saved as PNG.

Processed on your device — files are never uploaded.

How to convert PNG to WebP

  1. Drop PNG files.
  2. Keep WebP selected.
  3. Compress.
  4. Download.

Lossy WebP for photos, high quality for graphics

For photos, quality 75–80 is ideal. For logos and UI with sharp edges, raise quality to 90+ to avoid soft edges, or keep PNG and use lossy PNG compression instead.

Private by design

ShrinkVid never uploads your files. The page loads once, then all decoding and encoding happens on your device using the browser’s built-in WebCodecs API (hardware-accelerated video) and WebAssembly image codecs. That makes it safe for personal, confidential or work files — and there is no queue, no file size cap and no watermark. Read how it works.

Frequently asked questions

Are my files uploaded to a server?

No. ShrinkVid runs entirely in your browser. Files are read and encoded on your own device with WebCodecs and WebAssembly, so nothing is uploaded, stored or seen by anyone else. You can even disconnect from the internet after the page loads and it keeps working.

Is it really free? Is there a watermark or file size limit?

It is completely free with no watermark, no sign-up and no server-side file size limit. Because processing happens on your device, the only practical limits are your device’s memory and speed.
