Why Use a WebP Compressor? (Modern Next-Gen Web Optimization)
WebP is the modern image standard recommended by Google for optimal Core Web Vitals and fast page loading. However, exported WebP images from design software often contain default quality settings that can be further compressed.
Our WebP compressor re-encodes existing WebP photos and transparent graphics to strip unnecessary bytes while maintaining crisp resolution and smooth color transitions.
How WebP Compression Works (Predictive VP8 Encoding & Entropy Coding)
This WebP compressor uses the browser's image encoder with an adjustable quality setting. The result depends on the input and browser; compare actual bytes and visual detail before downloading.
You can open browser-supported WebP files, including lossless inputs, but this tool exports using a quality setting rather than a dedicated lossless mode. Inspect the result before downloading.
How to Compress WebP Online in 4 Easy Steps
- 1Choose one or more WebP images. A single image starts automatically; start a batch with the compression button.
- 2Adjust the quality setting and compare the before/after view.
- 3Check the actual bytes and pixel dimensions. If a form has a fixed KB limit, use the target-size tool.
- 4Download your preferred result or a ZIP of successful files.
A practical WebP comparison
Compare the original and compressed image at the size used on your site. Check transparent edges and gradients, then measure the actual output instead of assuming a percentage saving.
Match the tool to the requirement
A quality setting, a pixel width and a KB limit solve different tasks.
Key Benefits
