Free Online WebP Compressor
WebP is already an efficient format, but there's often still room to shrink a file further — especially for photos where a slightly lower quality setting makes little visual difference. LovePDFImg's Compress WebP tool re-encodes your images at a quality level you control, so you can find the right balance between file size and appearance.
Compression happens using your browser's Canvas API: each image is drawn to a canvas and re-exported as WebP at the chosen quality, with transparency preserved throughout. Drop in one image or a whole batch, adjust the quality slider, and download every compressed image together as a ZIP — all without uploading anything to a server.
