About the Compress WebP

WebP is already efficient, but re-encoding at a lower quality still yields big savings — ideal for web performance tuning. This tool re-encodes WebP files entirely in your browser with a live quality slider, perfect for hitting Core Web Vitals image budgets.

How it works

WebP is already efficient, but files exported at quality 90+ still carry headroom. The tool decodes your WebP through the browser's native codec and re-encodes it at your chosen quality, trimming bytes that barely change the picture. Because it all happens locally, a 10-file batch finishes in a blink.

How to use it

Drop your .webp files in, adjust the quality slider — 80 is a solid web default — and process. The results panel lists each file's new size and savings percentage, then you download individually or grab everything as a ZIP archive.

Supported formats & limitations

Input: .webp only (animated WebP uses its first frame), up to 10 files and 30MB each. Output is .webp. Compression is lossy here; if you need bit-perfect output, keep your original, since no tool can re-encode WebP without a fresh generation.

Common use cases

Handy when a downloaded WebP asset is heavier than expected, or when page-speed audits flag oversized hero images. Designers recompress exports from design tools; bloggers squeeze stock images before publishing; teams shrink UI assets for leaner bundles.

Frequently asked questions

Is my image uploaded to a server when I use Compress WebP?

Everything runs locally in your browser via the Canvas API. Your picture never leaves your machine — there is no upload step at all, so processing is as private as working in an offline editor.

What kind of image files work with this tool?

WEBP inputs are supported, up to 30 MB per file. For exotic formats, convert them first with one of the converter tools, then come back.

What are the size and batch limits?

You can queue 10 files per run, each up to 30 MB. Results download individually or bundled as a single ZIP.

Can I fine-tune the result before downloading?

The controls cover WebP quality. Nothing is baked in until you press the action button, and every run gives you a fresh preview to check.
