How to Compress WebP Images Online

WebP is already the smaller format compared to JPG and PNG - but for large photos or busy graphics, there's often still room to shrink it further without a visible quality hit.

How to Compress a WebP Image

LovePDFImg's Compress WebP tool reduces file size directly in your browser using a quality slider.

1. Open Compress WebP.
2. Upload your WebP image.
3. Adjust the quality slider and watch the estimated file size update.
4. Download your compressed WebP.

Finding the Right Balance

Because WebP is already efficient, over-compressing it shows up faster as visible artifacting than the same amount of compression would on a JPG. Start with a small reduction and compare the preview before pushing quality lower - for most web use, a subtle compression pass is all that's needed on top of the format's existing efficiency.

Common Reasons to Compress Further

• Hero images and banners - large, high-resolution WebP files that still weigh down a page's load time.
• Image-heavy galleries - dozens of WebP files where even a small per-image saving adds up across the page.
• Strict upload size limits - a platform or form that caps file size regardless of format.

Key Takeaways

• WebP can usually be compressed further even though it's already efficient.
• Compare quality carefully - WebP shows artifacts faster than JPG at heavy compression.
• Processing happens in your browser - images are never uploaded.
