About the JPG to WebP Tool
At matched visual quality, WebP generally produces a file 25–35% smaller than JPEG. On a page carrying a dozen photographs, that difference compounds into hundreds of kilobytes — the kind of saving that visibly moves your PageSpeed score and shortens load time on mobile connections.
The conversion is straightforward and happens entirely on your device. Your browser decodes the JPEG, redraws it to a canvas, and re-encodes it as WebP at whatever quality you choose. Nothing is uploaded, there is no queue, and you can convert as many files as you like without an account or a daily cap.
How to Use JPG to WebP
- Choose the JPG or JPEG file to convert.
- Set your target quality. 80–85% is a good default for photographs and is usually indistinguishable from the original.
- Press Convert and check the resulting file size.
- Download the .webp file.
When to Use This Tool
- Optimising blog and article photography for faster page loads
- Preparing product imagery for an online store where speed affects conversion
- Reducing CDN and hosting bandwidth on a high-traffic site
- Building modern-format sources for responsive
markup - Cutting the payload of an image-heavy landing page before launch
Things Worth Knowing
- Both JPEG and WebP are lossy. Converting between them adds a second generation of compression, so start from the highest-quality original you have.
- Because the source JPEG has no transparency, the WebP output will be fully opaque.
- Very small thumbnails sometimes show little benefit — the format overhead becomes proportionally significant.

Frequently Asked Questions
Does converting JPG to WebP lose quality?
Some, because you are re-encoding lossy data with a second lossy codec. At quality 80–85 the difference is generally invisible. To avoid stacking compression, convert from an original PNG or RAW file where possible.
How much file size will I save?
Typically 25–35% compared with a JPEG of equivalent visual quality. Photographs with smooth gradients tend to benefit most.
Should I replace all my JPGs with WebP?
For web delivery, generally yes. For files you email, archive, or hand to print vendors, JPEG remains more universally accepted by desktop software.
Can I convert several images at once?
Use the Bulk Converter tool, which handles multiple files in a single pass and applies the same settings to all of them.
