How to convert JPG to WebP
- Choose your files. Add JPG images. You can select up to 20 files per batch, within the displayed size limits.
- Set the result. WebP is already selected. Adjust dimensions and, for JPG, WebP or AVIF, quality. Check the transparency background where available.
- Convert and download. Download each result or the batch ZIP. Compare file size and appearance before replacing any original.
WebP output: Smaller web images. Transparency can be preserved when the source contains it.

Why websites switch photos to WebP
Image weight is often the largest part of a web page. WebP usually produces smaller files than JPG at a similar visual quality, so pages load faster and use less mobile data. All current major browsers display WebP, and most website builders and content management systems accept it. Converting your JPG library is a straightforward speed win when your platform supports the format.
Settings that work well for photos
Start at quality 80 to 90 and compare the result with the original at the size it will be shown. Savings vary by image: busy, detailed photos tend to shrink less than smooth ones, and a few already well-compressed JPGs may barely change. Resizing matters just as much. A 4,000-pixel photo displayed in an 800-pixel column wastes most of its bytes, so set the longest side close to the display size, often 1,280 or 1,920 pixels. WebP output also accepts a maximum size in KB.
Metadata is dropped, which suits the web
The WebP file is written without the JPG's EXIF data, so camera details and GPS coordinates do not travel to your website. That keeps files a little smaller and avoids publishing where a photo was taken. If you rely on embedded copyright or caption fields, add them back with your publishing tool. Color profiles are not carried over either.
Can you make WebP files without a converter?
Windows Paint and macOS Preview generally do not list WebP among their save formats, so there is no simple built-in route on most computers. Some site platforms convert uploads to WebP automatically; check your platform's media settings before converting by hand.
How ConvitAll encodes WebP
When your browser can export WebP, ConvitAll uses that built-in encoder. When it cannot, a WebP codec bundled with the site runs in a background worker on your device. Up to 20 JPGs can go through in one batch, and a ZIP gathers the results. No upload, no queue.
Questions and answers
How much smaller is WebP than JPG?
It varies with the photo and settings. WebP is often noticeably smaller at similar quality, but some images save little, and a JPG that was already heavily compressed may not shrink at all. Check the size shown for each result before replacing originals on your site.
What quality should I use for JPG to WebP?
Quality 80 to 90 is a good starting range for photos on websites. View the result at its real display size. If you need to hit a page-weight budget, use a maximum KB value and let the tool try lower qualities.
Do all browsers support WebP images?
Current versions of Chrome, Edge, Firefox and Safari all display WebP. Very old browsers and some email clients do not. If you send images by email or to an older system, JPG remains the safer format.
Does the WebP keep my photo’s EXIF and GPS data?
No. ConvitAll writes a new WebP without the original EXIF block, so location, camera model and capture time are left out. For web publishing that is usually helpful, since it avoids sharing where the photo was taken.
