Settings and trade-offs
- Compression or WebP conversion: select the original PNG, WebP and quality 80%. Dimensions stay 1200×800.
- Resizing: keep the aspect ratio locked and enter width 600; height becomes 400. Save as WebP at quality 80%.
- Already optimized JPG or WebP files may not shrink. Keep the original if the new file grows or text becomes blurry.
- Size presets unlock the aspect ratio. Changing 1200×800 to 1080×1080 stretches the image; it does not crop it.
Measured in Chromium on September 26, 2026. Sizes are file bytes divided by 1,024. This is one synthetic image, not an average photo compression rate. Output varies by browser and image. Open files at their original size to compare fine lines and text edges; the previews alone are not a quality assessment.
How do I convert PNG or JPG to WebP?
Choose your images, select WebP and create the results. Conversion preserves pixel dimensions. Transparency is supported, but animations export only the first frame.
| Option | Useful for | What to check |
|---|---|---|
| WebP | Web photos and transparent images | Check whether the destination accepts WebP |
| JPG | Photos without transparency | This tool replaces transparent areas with white |
| PNG | Transparency and sharp graphics | No quality slider; output may be larger |

How to use
- Choose PNG, JPG or WebP files.
- Keep WebP as the output format and adjust quality.
- Compare file sizes and previews, then download.
How it works
WebP conversion changes the file format while preserving pixel dimensions. Lower quality may reduce size at the cost of detail.
Common questions
Is transparency preserved?
PNG and WebP preserve transparency. JPG replaces it with white.
Why is the result larger?
Size depends on image content and format. Compare the result with the original or lower quality.
Multiple images and animations?
Process up to 20 files, 100MB total, sequentially. Download a ZIP when at least two results are ready. With aspect ratio locked, resizing calculates each height from its original proportions. Animations export the first frame only.
Is WebP always smaller?
No. An already compressed source or higher quality setting can produce a larger file. Compare the result size and preview.
Can I convert WebP to JPG too?
Yes. Select JPG as the output format. Transparent areas become white.
