Make the images on your website smaller: JPG, PNG, HEIC and more become WebP files that load faster and look just as good – one image or hundreds, without uploading anything.

Compression

Lossy suits photos. Lossless keeps every pixel of logos, screenshots and graphics – and is often still smaller than PNG.

80

90 is a good balance of sharpness and file size.

How to convert images to WebP

  1. Choose the compression

    Lossy for photos, lossless for logos, screenshots and graphics.

  2. Add your images

    JPG, PNG, HEIC, AVIF, GIF or BMP. All images in a batch get the same settings.

  3. Download

    Save each WebP or all of them as a ZIP.

Encoded on your device

KeepPixels uses Google's libwebp encoder, compiled to run in your browser. Your images are never uploaded, and the location in photos is removed by default.

Why WebP?

WebP was developed by Google for the web. It compresses better than JPG and PNG and supports transparency, so pages load faster without the images looking worse – something visitors notice and search engines measure.

JPG PNG WebP
File size for photos Small Very large Smallest
Transparency No Yes Yes
Lossless mode No Yes Yes
Shown by browsers All All All current ones

When to use WebP

  • Photos and banners on your own website or online shop.
  • Product pictures for platforms that accept WebP.
  • Graphics with transparency that would be large as PNG.

Need the opposite? WebP to JPG converts WebP files for programs that can’t open them. To shrink files further, resize the images as well.

Frequently asked questions

How much smaller is WebP than JPG?

At a similar visual quality, a WebP is usually noticeably smaller than a JPG and much smaller than a PNG. How much depends on the picture – the result list shows the saving for every file.

Lossy or lossless?

Lossy for photos: quality 80 looks like the original at a fraction of the size. Lossless for logos, screenshots and graphics with sharp edges – it keeps every pixel and is often still smaller than PNG.

Is transparency kept?

Yes. WebP supports transparency in both modes, so PNG logos keep their transparent background.

Do all browsers support WebP?

All current versions of Chrome, Edge, Firefox and Safari show WebP. Some older programs and upload forms still accept only JPG or PNG.

What happens to the photo details?

The location is removed and the other details are kept, unless you choose otherwise.

Are my images uploaded?

No. Everything happens in your browser.
