Reduce WebP File Size in Your Browser
WebP is a modern image format from Google that delivers smaller files than JPEG or PNG at the same visual quality. This tool re-encodes your existing WebP images at a quality level you choose, trimming extra bytes for faster page loads and lighter assets — ideal when you already serve WebP and want it leaner still.

How to Compress a WebP File
Add Your Images
Drag and drop WebP files onto the upload zone, click to browse your device, or paste an image from the clipboard with Ctrl+V. Load up to 20 images in a single batch.
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, and the preview updates live as you adjust.
Preview & Compare
Click a thumbnail to open the side-by-side preview, compare the original with the compressed version, and check the exact percentage saved before you commit.
Download
Save each compressed image individually, or use Download All to grab the whole batch — three or more files are bundled into one ZIP.
WebP Compressor Features
Adjustable Quality
A precise 1–100 slider gives you full control over the trade-off between file size and image fidelity, with live recompression on every change.
Transparency Preserved
Compression runs through the HTML canvas, which keeps the alpha channel — transparent WebP images stay transparent in the output.
Batch Compression
Process up to 20 images in one go and export them together as a ZIP archive when you have three or more files.
Fully Browser-Based
No uploads, no sign-up, no waiting. Everything runs locally for total privacy and instant results.

WebP Compression FAQ
How do I compress a WebP image?
Add your WebP files by drag-and-drop, file browse, or clipboard paste, then move the quality slider to your target level. The tool recompresses each image live in the browser; download them individually or as a ZIP.
Can I compress WebP without losing quality?
WebP compression here is lossy, so higher quality values keep more detail. Set the slider to 90–100 for near-lossless results, or lower it to squeeze out more size. Preview the before/after to find the point where the file gets smaller without a visible drop.
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.
How many WebP images can I compress at once?
Up to 20 images per batch. Each one is compressed independently the moment it is added. When you have three or more files, Download All bundles the results into a single ZIP archive; with fewer, they download separately.
Is WebP supported by all browsers?
Yes. All current browsers — including Chrome, Firefox, Safari, and Edge — display WebP images, which makes it a safe default for the web today.
Are my images uploaded to a server?
No. All compression happens entirely in your browser. Your images never leave your device, which keeps the tool safe even for private or unpublished assets.
