WebP Compressor

Need to compress WebP files? WebP is Google's modern image format — introduced in 2010 to replace JPEG and PNG with 25-35% better compression at equivalent quality. WebP supports both lossy and lossless compression, plus alpha transparency (like PNG). Despite being more efficient than JPEG, WebP files are often poorly encoded at the source — Photoshop, Squoosh, and other tools default to high quality settings. This WebP compressor re-encodes using the browser's native Canvas API with optimized quality, typically reducing file size 30-60%.

• 1WebP is more efficient than JPEG (25-35% smaller at same quality) — modern websites should default to WebP for image assets.
• 2Browser support is universal in 2026 — all modern browsers support WebP natively, including Safari (since 2020) and iOS (since 14).
• 3Local processing avoids uploading web assets to third-party servers. Critical for unreleased product photos and proprietary design assets.
• 4Free, no account, no watermark — compress as many WebPs as you need. The tool runs the Canvas API natively; there's no server cost.
• 5Transparency preservation: WebP output keeps alpha channel intact — modern alternative to PNG with 25-35% smaller file size.
• 6Quality 80 is the sweet spot — visually identical to source for most web content, 30-50% smaller than default exports.
