WebP Converter

Convert your image into the modern, smaller-sized WebP format.

When should you use this?

Use this when you want to convert images to the modern, small-file WebP format to speed up your website's page load.

When shouldn't you use this?

If you're uploading to an older system or an app that doesn't support WebP (rare but still happens), JPG or PNG is the safer choice.

Step-by-step

  1. Pick the file you want to convert in 'Image (JPG/PNG)'. Only JPG and PNG files are accepted.
  2. If you have the same image in several sizes, choose the one closest to the size it will appear on your site.
  3. Click 'Convert to WebP and download'. The conversion runs in your browser and the WebP file downloads automatically when it's ready.
  4. Compare the new file size with the original and open the image to check the quality.

Example

A small guesthouse website shows room photos taken on a phone, and the page loads slowly on mobile. Resizing the photos to the width they're actually displayed at, then converting them to WebP, usually cuts the file size noticeably. Swap the image links on the site for the new files and measure the page load again to see the difference.

Screenshots and logos saved as PNG are worth trying too. Zoom in on the result, since fine text and sharp edges are where conversion problems tend to show first.

Converting to WebP

The tool redraws a JPG or PNG image in your browser, saves it as WebP at 92% quality and downloads it as converted.webp. Only JPG and PNG are accepted as input. Transparency in a PNG is kept in the WebP. At similar visual quality WebP usually produces a smaller file than JPG or PNG; the gain depends on the image's content. The quality value is fixed and cannot be adjusted in the tool.

When converting

  • The output is a redrawn copy of the image; embedded information such as EXIF (capture date, location) is not carried over.
  • JPG is already compressed, so converting from JPG to WebP may lower quality slightly. Don't delete the original.
  • WebP is supported by all modern browsers today, but older software and some email clients may not open the file.
  • Before using it on a website, check the image and the file size on the page; if the saving is smaller than expected, keep the original format.

Things to keep in mind

  • Keep your original JPG and PNG files. If you later need a different size or format, you'll want to start from the best source you have.
  • If you converted a PNG with a transparent background, view the result on both a dark and a light background to confirm the transparency survived.
  • An image that's already small and well compressed may barely shrink. Don't expect a big saving on every file.
  • Email clients support WebP less consistently than web browsers do, so JPG or PNG is still the safer choice for newsletters.
