Why use this tool
Lighter page weight
WebP usually stores photos in fewer bytes than JPG at similar visual quality, so galleries and product pages download faster.
Tune the quality
Start from the default of 85 and move the slider to trade a little detail for a smaller file, or the reverse.
Whole folders at once
Convert up to 200 photos per batch in your browser, then grab them all in a single ZIP.
Supported formats
Use cases
Speeding up a blog
Article header photos are the heaviest part of each page. Converting them to WebP trims page weight without changing the layout.
Online store product shots
A shop has hundreds of JPG product photos. Convert them in batches and upload the WebP versions to the store’s media library.
Page speed audits
A performance report suggests serving images in next-gen formats. WebP is supported by all current major browsers and is a simple first step.
Technical details
This conversion is lossy to lossy: the JPG is decoded and encoded again as WebP, so keep your original JPG files as masters. Re-encoding can’t fix existing JPG artifacts, and very low quality settings add new ones. A WebP at quality 75–85 is usually a good balance for photos on the web. If a converted file happens to come out larger than the JPG, try a lower quality.
All current major browsers display WebP, but some older desktop software, print services and email clients still expect JPG. That’s why many sites keep both versions. Camera EXIF data, including GPS, isn’t copied into the WebP, which is usually what you want for public web images, and the photo’s orientation is applied to the pixels so nothing appears sideways. For a broader comparison, read WebP vs JPG.

Frequently asked questions
Is WebP better than JPG?
For web pages, usually yes: WebP typically produces smaller files at similar visual quality. JPG is still more widely accepted by older software, printers and upload forms. Many sites serve WebP to browsers and keep JPG originals for everything else.
What quality should I use for JPG to WebP?
The default of 85 keeps photos looking close to the original. For large hero images or galleries, 70–80 often looks the same on screen and saves more. Check the new size and preview before deciding on a whole batch.
Does converting JPG to WebP lose quality?
Slightly, because both formats are lossy and the photo is compressed a second time. At sensible quality settings the difference is hard to see. Keep your original JPG files so you can always convert again from the source.
Will WebP images work in every browser?
Current versions of Chrome, Edge, Firefox and Safari all display WebP. Problems usually come from older desktop apps or services outside the browser, which is where keeping a JPG copy helps.
