PNG to WebP

Why convert PNG to WebP

• WebP supports transparency. According to Google, a lossy WebP image with transparency is usually about one third of the size of the same image in PNG.[1][2]
• Chrome, Edge, Firefox and Safari can all display WebP.[3][4]

How to convert

1. “Convert to WebP” is already selected in Step 1. For a smaller file, please lower the quality.
2. In Step 2, choose or drag in your PNG files. You can add several at once, and conversion starts automatically.
3. In Step 3, check the results and download one image, or all images as a ZIP file.

What changes after converting PNG to WebP

• This tool exports still images. If the original is animated, only the first frame is kept.
• The converted image does not contain the shooting information (EXIF) of the original, such as the date, camera model and location. The image is turned upright according to the orientation recorded in the original.

Frequently asked questions

Why is WebP not available in Safari?

The web canvas in Safari cannot export WebP, so in Safari this tool can export only JPG and PNG. Please use Chrome, Edge or Firefox.[5]

What quality setting should I use?

Set the quality in Step 1. The range is 10–100, and the default is 90. A higher value gives better quality and a larger file. If the upload has a size limit, lower the quality and check the converted size in the list in Step 2.

Is the WebP file larger or smaller than the original PNG file?

This tool encodes WebP with lossy compression at the quality set in Step 1, so the WebP file is usually smaller than the original PNG. The size of each file before and after conversion is shown in the list in Step 2.[1]

Can I convert several images at once?

Yes. You can select or drag in up to 100 images at a time. When all images are converted, you can download them one by one or together as one ZIP file.

About the PNG format

• PNG is a W3C Recommendation. The current version is the third edition, published in 2025. PNG uses lossless compression and supports transparency (an alpha channel).[6][3]
• The third edition adds animated PNG (APNG) to the standard. Software that does not support animation shows only one still image.[6]
• All major browsers support PNG.[3]
