Why convert JPG to WebP
Images are usually the heaviest part of a web page. Switching photos from JPG to WebP cuts their size without a visible drop in quality, so pages load faster, use less mobile data and score better on speed tests such as Google’s PageSpeed Insights, which often suggests serving images in next-gen formats.
This converter is useful for:
- bloggers and shop owners preparing photos before uploading them
- web developers converting a folder of images for a site
- anyone who needs to fit more photos under an upload size limit
How to use this converter
Choose one or more JPG files, or drop them on the box above. Each photo is converted by your browser and gets a download button, with the old and new size side by side so you can see the saving.
Choosing a quality setting
WebP quality numbers don’t match JPG ones exactly, but the same idea applies: lower means smaller. 80–85% is a good starting point for website photos. For large hero images where detail matters, try 90%. For thumbnails, 65–75% is usually fine. Converting a JPG that was already heavily compressed won’t shrink it much further at high quality settings; lower the quality instead.
What changes in the converted file
- Metadata such as camera settings and GPS location is removed.
- Orientation is applied, so sideways phone photos come out upright.
- Dimensions stay exactly the same. Large camera photos are still large; resizing them for the web saves even more space.
Keep your originals
WebP is a lossy format here, and converting from JPG means compressing an image a second time. Keep your original JPG files as the master copies, and use the WebP versions for publishing.
Using WebP files on your site
Most website platforms accept WebP uploads directly. WordPress has supported them since version 5.8, and Shopify, Wix, Squarespace and Webflow all accept WebP images. On a hand-built site, use the .webp file in a normal img tag; every current browser displays it, so a JPG fallback is no longer needed for most audiences.
Questions
How much smaller will my images be?
Google's own tests found lossy WebP files 25 to 34 percent smaller than JPG at the same visual quality. Your result depends on the photo and the quality setting; the size change is shown for each file.
Do all browsers show WebP images?
Yes. Chrome, Edge, Firefox, Safari and Opera all display WebP, including on phones. That's why it is safe to use on websites.
Does it work on iPhone and in Safari?
Yes. Safari can't create WebP files on its own, so this converter brings its own WebP encoder (Google's libwebp). It produces the same files in every browser, including on iPhone and iPad.
Is EXIF data removed?
Yes. Camera details and GPS location are not copied to the WebP. That makes files smaller and safer to publish.
