Quick answer
A JPG to WebP converter decodes each image and saves it again in Google's WebP format. Google reports lossy WebP files are 25 to 34% smaller than comparable JPEGs. Use quality 75 to 85 for photos, keep the original as a backup, and update your img tags or let your CMS serve the WebP version.
What is a jpg to webp converter?
A JPG to WebP converter is a tool that re-encodes JPG or PNG images as WebP, a format made by Google that supports lossy and lossless compression plus transparency. Size change = (WebP bytes minus original bytes) ÷ original bytes × 100.
How do you use the JPG to WebP Converter?
- Choose one or more JPG or PNG files; a sample JPG is converted first so you can see the result.
- Set the WebP quality; 80 is a safe start for photos.
- Optionally set a max width to resize large photos while converting.
- Check the table for each file's old size, new size and saving.
- Download each WebP file and upload it to your site in place of the original.
Is WebP better than JPG?
For websites, usually yes: Google's WebP documentation reports lossy WebP is 25 to 34% smaller than JPEG at the same SSIM quality, and WebP also supports transparency. JPG is still the safer choice for email attachments, printing and very old software.
Do all browsers support WebP?
Yes, all current major browsers, including Chrome, Edge, Firefox and Safari, display WebP images. For very old browsers you can use a picture element with a WebP source and a JPG fallback in the img tag, as described on MDN's picture element guide.
Does converting to WebP help SEO?
Converting to WebP helps SEO indirectly by making pages lighter and faster, which supports good Largest Contentful Paint. Google Search indexes WebP images like JPG and PNG. Keep descriptive file names and alt text when you swap formats, and update internal references so no image breaks.

Worked example
Example
Example: a 1600 x 900 px JPG product photo saved at high quality converts to WebP at quality 80. Lossy WebP is often a third or more smaller for photos like this, so a 400 KB file might drop to roughly 250 KB or less. The exact saving depends on the image, which is why the table shows the real result for each file.

Frequently asked questions
Are my images uploaded when I convert them?
No. The converter uses your browser's canvas to decode and re-encode each image, so files never leave your device. Large batches depend on your device's memory, so convert very big photos a few at a time.
Can I convert PNG to WebP with transparency?
Yes. WebP supports an alpha channel, so transparent areas in a PNG stay transparent in the WebP file. Check edges around logos in the preview, and use quality 90 or above when sharp lines matter.
Why is my WebP file bigger than the JPG?
A JPG that is already heavily compressed can grow when re-encoded at a high WebP quality. Lower the quality a little, or keep the original JPG for that file. The converter marks any file that got bigger so you can decide.
What WebP quality should I use?
Use 75 to 85 for most photos and 90 or above for images with text or fine lines. Lower values such as 60 suit large background images. Always compare the preview at full size before replacing images on a live site.
How do I use WebP images on WordPress?
WordPress has supported WebP uploads since version 5.8, so you can upload the converted files directly to the Media Library. Many image plugins can also create WebP versions automatically and serve them to browsers that support the format.
Does converting JPG to WebP remove EXIF data?
Yes. Re-encoding through a canvas copies only the pixels, so camera EXIF data such as GPS location, camera model and date is not kept in the WebP file. That helps privacy but also removes any copyright notice stored in metadata.
