Options
- Quality: from 100 (largest, most faithful) down to 60 (smallest).
- Target size: choose a limit such as 50 KB, 100 KB, 200 KB or 500 KB. The tool finds the highest quality that fits. If even the lowest quality is too large, it also scales the image down a little.
- Maximum size: limit the longest side to 4000, 3000, 2000, 1600 or 1200 pixels. The aspect ratio is kept, and small images are never enlarged.
- Rotate and flip: turn the image 90, 180 or 270 degrees, or mirror it left to right.
Transparency is always kept, so there is no background color to choose.
How to convert with options
- Choose the options first.
- Add the PNG files. They are converted with the current options.
- If you change an option later, click Convert again to apply it to the whole list.
- Download each WebP or one ZIP.
Pick a size that fits the job
Image weight is one of the biggest parts of most pages. A target size gives you a hard limit instead of guessing a quality number. The values below are common starting points, not rules.
| Target | Where it fits | Try |
|---|---|---|
| 50 KB | Thumbnails, small cards, icons | Target 50 KB, maximum size 800 px or 1200 px |
| 100 KB | Blog and article images | Target 100 KB, maximum size 1600 px |
| 200 KB | Product photos, hero images | Target 200 KB, maximum size 2000 px |
| 500 KB | Large banners and full-width backgrounds | Target 500 KB, maximum size 3000 px |
A smaller width often saves more than a lower quality. A PNG screenshot at 3000 pixels shown at 1000 pixels on the page wastes most of its bytes, so set a maximum size that matches how large the image is displayed, and allow for high-density screens by going up to twice the display width.

For a plain conversion use PNG to WebP. To resize without changing the format use the image resizer, and to crop first use the image cropper. For photos, see convert JPG to WebP to a target size. The WebP guide shows how to serve the result with a fallback.
