How do I use the WebP Image Compressor?

To compress a WebP image online, add your WebP files above, set a quality (about 70 to 80 suits most images) or tick Lossless, then press Compress. The files are re-encoded with libwebp in your browser. Nothing is uploaded, and if the result is not smaller you keep your original.

About the WebP Image Compressor Online by Websolindia

Squeeze WebP images even smaller. Re-encode them at a lower quality for the biggest saving, or use lossless mode to keep pixels identical, with transparency preserved either way. It is a free tool from Websolindia, a New Delhi website design and SEO company that builds fast, image-optimised websites.

Unlike most online image tools, this one does not upload your pictures. Your browser decodes each image, re-encodes it with an open-source compression engine and shows you the exact before and after sizes. You can process up to 30 images at a time and download them one by one or together as a ZIP.

Once your image is ready, you may also want the AVIF Image Compressor Online, the JPG Image Compressor Online or the JPG to WebP Converter Online. All of our free image tools are listed in the Image Compressor Tools collection and the Websolindia Image Converter.

When to Use the WebP Image Compressor

  • WebP images on a website that are still heavier than they should be.
  • Transparent WebP graphics where you want a smaller file than PNG.
  • Reducing the size of an image library before uploading it to a CMS.
  • Preparing images for a performance budget, which you can verify with our Website Performance Analyzer.

What to Watch For

  • Lossy WebP re-encoding adds a second round of compression to an already lossy file. Use quality 70 or above and check the result.
  • Lossless mode is exact but can produce larger files than a lossy WebP.
  • Animated WebP files are processed as a still image (first frame only).
  • Metadata is not copied to the result.

StepWhat happens
1. Read and decodeThe WebP is decoded to pixels by your browser.
2. Resize (optional)A maximum width scales larger images down; images are never enlarged.
3. Encode with libwebpThe pixels are encoded as WebP at your quality, or losslessly, by your browser's encoder or by libwebp compiled to WebAssembly.
4. Compare with the originalIf the new file is not smaller than your original, we return your original instead.

WebP Image Compressor Online — Frequently Asked Questions

Is WebP compression lossy or lossless?

Both are available. Lossy trades some detail for a much smaller file; lossless keeps every pixel. The tool offers both.

How much smaller will the WebP be?

It depends on the image and quality. Google reports lossy WebP is typically 25 to 34 percent smaller than comparable JPEG and lossless WebP about 26 percent smaller than PNG; recompressing an existing WebP saves less.

Will transparency be kept?

Yes, in both lossy and lossless modes.

Why did the file not get smaller?

If it was already well compressed, our result was not smaller, so your original is returned unchanged.

Should I use AVIF instead?

AVIF is often smaller still but slower to encode and less widely supported. Try the AVIF Image Compressor Online and keep a WebP or JPG fallback.

Can I convert WebP to another format?

Yes: the WebP to JPG Converter Online and the WebP to PNG Converter Online convert WebP for software that does not support it.

Is the WebP Image Compressor Online free to use?

Yes. It is free, needs no sign-up, adds no watermark and has no daily limit. It is provided by Websolindia.

Are my images uploaded to a server?

No. Your images are read and processed inside your browser on your own device. They are never sent to Websolindia or anyone else, which is why the tool is safe for private photos.

Does the tool keep EXIF and location data?

No. New files are created from the pixels, so camera details, GPS location and other embedded metadata are not copied. Keep your originals if you need that information.

How many images and how large can they be?

Up to 30 images per batch and 150 MB per image. Images above roughly 120 megapixels are declined with a clear message rather than freezing your browser.

Which browsers and devices does it work on?

Current versions of Chrome, Edge, Firefox and Safari on computers, phones and tablets. Large images and AI or AVIF features run faster on a computer.
