Compress WebP Images

WebP is a modern image format developed by Google that delivers noticeably smaller files than JPEG or PNG at the same visual quality. This tool re-encodes your WebP images at a quality level you choose, squeezing out extra bytes for faster page loads and lighter assets — ideal when you are already serving WebP and want it leaner still.

100% private: every image is compressed directly in your browser using the HTML canvas. Nothing is uploaded to a server, so your files never leave your device.

Common Use Cases

Web Performance

Serve the lightest possible images to boost page-load speed and Core Web Vitals scores.

Modern Pipelines

Optimize WebP assets for CDNs, app bundles, and static sites where every kilobyte counts.

Bulk Optimization

Compress up to 20 WebP files at once and download them all in a single ZIP archive.

How to Compress a WebP

1

Add Your Images

Drag and drop WebP files onto the upload zone, click to browse your device, or paste an image straight from the clipboard. You can load up to 20 images in a single batch.

2

Set the Quality

Drag the quality slider from 1 to 100 (or type an exact value). Lower numbers mean smaller files; higher numbers keep more detail. The default of 80 suits most images.

3

Preview & Compare

Open the side-by-side preview to compare the original and compressed versions and check the percentage saved before committing.

4

Download

Save each compressed image individually, or use Download All (ZIP) to grab the entire batch in one click.

Tip: WebP supports transparency. When you compress a transparent WebP here, the canvas keeps the alpha channel, so transparent areas are preserved in the output.

Features

Adjustable Quality

A precise 1–100 slider gives you full control over the trade-off between file size and image fidelity.

Superior Compression

WebP typically produces 25–35% smaller files than JPEG at equivalent quality, with support for both lossy and transparent images.

Batch Compression

Process up to 20 images in one go and export them together as a ZIP archive.

Fully Browser-Based

No uploads, no sign-up, no waiting. Everything runs locally for total privacy and instant results.

Frequently Asked Questions

What is WebP?

WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web, along with support for transparency and animation.

Is WebP supported by all browsers?

Yes. All modern browsers — including Chrome, Firefox, Safari, and Edge — support WebP images, which makes it a safe default for the web today.

How much smaller are WebP files than JPEG?

WebP typically produces files 25–35% smaller than JPEG at equivalent visual quality. Recompressing an existing WebP at a lower quality with this tool can trim it even further.

Does this preserve WebP transparency?

Yes. The compression runs through the HTML canvas, which keeps the alpha channel, so transparent WebP images stay transparent after compression.

Are my images uploaded to a server?

No. All compression happens entirely in your browser. Your images never leave your device, which makes the tool safe even for private or unpublished assets.
