Image to WebP

Convert PNG, JPG, GIF, BMP, or TIFF images to WebP in your browser with adjustable quality.

About WebP Format

WebP is a modern image format developed by Google that provides superior compression for images on the web. WebP images are typically 25-35% smaller than comparable JPEG images and support transparency like PNG.

Benefits of WebP

  • Smaller file sizes - up to 34% smaller than JPEG
  • Adjustable lossy quality for a practical size-versus-detail balance
  • Supports transparency (alpha channel)
  • Widely supported by modern browsers

Convert a still image to WebP with a quality setting you control. Processing uses your browser, so the selected file stays on your device during conversion.

What is an image to WebP converter?

This tool decodes a supported still image with the browser and exports a WebP file from a canvas. WebP can be efficient for web delivery, but the size saving depends on the source image and quality setting.

When to convert an image to WebP

Website images

Create a modern web image when your visitors' browsers can decode WebP.

Smaller photo copies

Try a lower quality setting for a smaller copy of a JPEG or PNG photo.

Transparent graphics

Use a source with alpha transparency when you need transparent pixels in the result.

How image to WebP conversion works

The browser reads the selected image, draws it to an HTML canvas, and requests an image/webp blob at the chosen quality. The export is a still image and cannot add detail that was absent from the source.

WebP compared with PNG and JPEG

WebPWeb deliveryQuality-controlled export; savings vary by image.
PNGGraphics and alphaLossless encoding, often larger for photos.
JPEGPhotographs and sharingWidely recognized lossy format without transparency.

Browser and file support

The converter uses browser image decoding and canvas export. It accepts JPG, JPEG, PNG, GIF, BMP, and TIFF selections; decoding of a particular file still depends on the browser. Animated GIF input is exported as a still WebP frame.

WebP conversion limits

The tool exports one still WebP with a lossy quality setting. It does not offer a lossless toggle, restore compressed detail, or guarantee that every browser can decode every source file.

Frequently Asked Questions

Can I convert PNG or JPG to WebP?
Yes. Select a browser-readable PNG, JPG, JPEG, GIF, BMP, or TIFF image and choose the quality before downloading WebP.
Will WebP always be smaller?
No. Results depend on the source pixels, existing compression, and quality setting; compare the output size for your image.
Are my images uploaded?
Conversion runs in the browser and does not require uploading the selected image to a server.
