Why convert images to WebP?

WebP supports lossy and lossless compression plus transparency in one format. Google's compression study measured lossy WebP files about 25–34% smaller than JPEG at equivalent quality, which means faster page loads and less bandwidth.

Does WebP keep transparency?

Yes. WebP stores an 8-bit alpha channel even in lossy mode, so transparent areas from PNG, GIF, or ICO sources are kept instead of being filled with a background color.

Which browsers can display WebP images?

Current versions of Chrome, Edge, Firefox, and Opera display WebP, and Safari has supported it since version 14 on iOS 14. Keep a JPG or PNG fallback only if you still serve very old browsers.

Which image formats can I convert to WebP?

JPG, PNG, BMP, GIF, and ICO files, each up to 5000x5000 pixels.

Convert JPG, PNG, BMP, GIF, and ICO images to WebP online instantly. Fast, secure, high-quality client-side conversion with no upload required.

Convert JPG, PNG, BMP, GIF, and ICO images to WebP in your browser. Each image is encoded as lossy WebP at 92% quality with its alpha channel kept, so one format can replace both JPG photos and transparent PNG graphics on a web page—usually at a smaller file size. Resize if needed, then download single .webp files or a ZIP of the batch; nothing is uploaded.

How to Convert Images to WebP

1
Choose images to convert
Drag and drop or select one or more JPG, PNG, BMP, GIF, or ICO files (up to 5000x5000px each). Animated GIFs are saved as a still WebP image.
2
Match the display size (optional)
Set a width, a height, or both; one empty field keeps the aspect ratio. Scaling an image to the size it is shown on your page saves more bytes than any encoder setting.
3
Encode to WebP
Click "Convert All" to compress every image to WebP at quality 0.92 in your browser—transparent areas are not filled in.
4
Get your .webp files
Use "Download" for one file or "Download All" to receive the whole batch as a ZIP archive.
