About WebP Compression
WebP is a modern image format from Google that covers both JPEG (lossy photos) and PNG (transparent assets) use cases: its lossy mode uses intra-frame prediction from VP8 video coding, producing files about 25-35% smaller than JPEG at the same quality, and its alpha channel compresses far better than PNG.
Compatibility is no longer a concern: Chrome, Edge, Firefox, and Safari 14+ all support WebP, so it is safe for websites and mini-programs. Batch-converting site images from JPG/PNG to WebP is one of the most cost-effective ways to speed up page loading.
What users say
I process dozens of product images for new listings every day. Now I drag the whole batch in, and it compresses and zips everything automatically — main images drop from 800-900KB to around 100KB. Uploading is so much faster.

The application system required photos under 200KB and I could never hit it by tweaking quality myself. The target-size feature took 200 and nailed 199KB on the first try. Submitted successfully.

I convert all illustrations to WebP and compress them — articles load noticeably faster. Batch processing plus format conversion in one step, no more hopping between apps.
