How to png to webp

  1. Drop the PNG.
  2. Pick a quality.
  3. 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 this in code

curl -X POST https://api.fylane.dev/v1/jobs \

    "file_id": "<file id>",
    "operation": "image.convert",
    "options": {
      "format": "webp",
      "quality": 82
    }
  }'

The same operation, image.convert — Re-encode to WebP, JPEG, PNG or AVIF at your quality. Upload first with the quickstart; every option is on the operations page. 500 free credits a month, then $5 per thousand.
