How to use JPG to WebP

  1. Add one or more JPG files.

  2. Set the WebP quality — 80% is a sensible default for photos.

  3. Click Convert to WebP and compare the size reduction shown per file.

  4. Download the WebP files.

About this tool

WebP typically encodes photos 20–35% smaller than JPG at comparable visual quality, which makes pages load faster and improves Core Web Vitals. This tool re-encodes your JPG locally and shows the original size, the new size and the percentage saved so you can judge whether the trade-off is worth it for each image. All modern browsers support WebP; only very old software does not.

If you run a website or blog, swapping JPG images for WebP is one of the easiest wins for page speed — it requires no visual redesign, just smaller files serving the exact same photos to visitors.

Common ways people use this

  • Shrinking blog or product photos before uploading them to a website to improve load times
  • Reducing the size of images bundled into an app or email template
  • Testing how much smaller a set of photos could be before committing to a site-wide format switch

Tips for better results

  • 80% quality is a solid starting point for photos — check the percentage-saved figure and adjust if you want more or less compression.
  • Keep a JPG fallback available only if your audience includes users on genuinely outdated browsers; otherwise WebP alone is fine today.

Frequently asked questions

How much smaller will my images get?
It depends on the photo, but 20–35% smaller than the source JPG at similar quality is typical. The tool shows the exact saving for each file after conversion.
Is WebP safe to use on my website?
Yes. Every current browser supports WebP. If you must support very old browsers, keep a JPG fallback.
Does converting twice lose quality?
Each lossy re-encode discards a little detail. Convert from the highest-quality source you have rather than re-converting repeatedly.
Will WebP hurt my SEO or image search rankings?
No — search engines index WebP images normally, and the faster page load from smaller files is generally a positive ranking signal, not a negative one.
Can I convert a whole batch of product photos at once?
Yes, add multiple JPGs together and each will be converted with the same quality setting, ready to download individually.
