Compress WEBP Images

WebP is already one of the most efficient image formats, but it can still be compressed further. Our SSIM-based optimizer analyzes each image and finds the lowest quality setting where the visual difference is imperceptible.

How WEBP Compression Works

WebP uses a predictive coding scheme related to VP8 video compression. Like JPEG, quality can be adjusted from 0-100. Our compressor performs a binary search across quality levels, comparing each result against the original using SSIM (Structural Similarity Index). The result is the smallest possible file that still looks identical to your eye.

Tips for WEBP Compression

  • WebP is already efficient — expect 20-50% savings (less than JPG)
  • WebP files exported at quality 100 will see the biggest savings
  • For maximum compression, consider using Medium or Low quality level
  • WebP supports both lossy and lossless — our compressor handles lossy

WEBP Compression FAQ

Is WebP already compressed? Can it be compressed further?

WebP files are often saved at higher quality than necessary. Our compressor finds the optimal quality where further reduction would be visible, typically saving 20-50%.

Does WebP compression preserve animation?

Our compressor currently handles static WebP images. Animated WebP support may be added in a future update.

Should I use WebP instead of JPG?

WebP typically produces 25-35% smaller files than JPEG at equivalent quality. If your target audience uses modern browsers (95%+ support), WebP is the better choice.
