What is Image → WebP?

WebP was designed as the modern replacement for JPG and PNG. It supports both lossy and lossless compression, plus transparency, and typically produces 25-35% smaller files than JPG at the same perceived quality. Every modern browser can display WebP, so it's a low-friction win for web performance. This tool encodes to WebP entirely in your browser — batch, no upload, no watermark.

  1. 1Drop JPG, PNG, or GIF files onto the drop zone.
  2. 2Choose a WebP quality (default 92%).
  3. 3Click 'Convert to WebP' — the tool encodes each image via HTML Canvas.
  4. 4Download individually or in batch.

Tips & Best Practices

  • ▸WebP quality behaves like JPG quality — 90% is visually indistinguishable from the source.
  • ▸For lossless PNG-like output, use a lossless-focused encoder (this browser tool always uses WebP's lossy mode).
  • ▸If you still need to support Internet Explorer or macOS <11 Safari, keep a JPG/PNG fallback.

Frequently Asked Questions

Does WebP support transparency?

Yes, WebP has a full alpha channel like PNG. The tool preserves transparency from the source.

Can old browsers open WebP?

Chrome, Firefox, Safari (14+), and Edge all support WebP. Internet Explorer 11 doesn't. If you need IE support, keep a JPG/PNG fallback.
