When to use JPG to WebP

Your Shopify store's product photos are bloating page load times and Google's PageSpeed report is flagging them. Drop the JPGs here and the browser's `<canvas>.toBlob('image/webp')` call re-encodes each one — typically 25–35% smaller at the same perceived quality. The whole batch processes in the tab with no upload, so you keep the original files untouched on disk. What you get back are WebP files ready to drop straight into your theme's `/assets` folder or a Cloudinary upload. Useful any time you're preparing a hero image for a blog post, compressing a portfolio thumbnail, or meeting a Core Web Vitals target before launch.

  • Compress a hero image before pushing a blog post live
  • Shrink product photos to hit a Shopify PageSpeed target
  • Batch-convert portfolio thumbnails before uploading to a CDN

Frequently asked

Is this JPG to WebP converter private? Do you upload my images?
No uploads. The conversion runs on your computer — your images are not uploaded anywhere and the tool works offline.
Why convert JPG to WebP?
WebP files are typically 25-35% smaller than JPG at equivalent quality, making them ideal for websites and apps where fast loading matters.
Does WebP support transparency?
Yes — unlike JPG, WebP supports transparency (alpha channel). Converting from JPG won't add transparency, but you won't lose quality either.
Will my JPG metadata be preserved?
The visual content is preserved but EXIF metadata (camera info, GPS) is stripped during conversion. This can actually improve privacy.
