Quick steps
How to convert JPG to WebP
Choose quality
Try the default, then check the size and visible detail.
Download the WebP
Save it if the result looks right and your destination accepts WebP.
A few useful details
Make a WebP copy for a compatible website
WebP is worth trying when a website needs lighter photographs. Select the JPEG, choose a quality setting and compare the exported size. Keep the original until you have checked the new copy.
You will not save the same percentage on every image. A detailed camera photo and an already optimised JPEG behave differently. Look at small text, faces and edges before choosing the smaller file.
Check that your website or app accepts WebP. If you are preparing a government form or sending a file into an older workflow, JPG may still be the format it asks for.
Before you save the result
The output format is WebP. Always check that the destination accepts that extension.
The original file stays unchanged; download a separate copy only after checking the preview.
Check the website workflow before switching formats
Try the new format on one image first
Before replacing a whole folder of website assets, convert one representative photograph. Check that your content editor accepts WebP, displays it correctly and uses it in the intended placement. That is more useful than assuming a smaller extension automatically fits the whole workflow.
Compare the important parts at the same size
Judge the original and export at the same display size. Fine lettering, facial features and edges against a plain background can reveal visible loss. A small thumbnail view may hide differences that become obvious on a larger product or detail page.
Choose dimensions as well as quality
Converting the format keeps the decoded pixel dimensions in this tool. If the image is far larger than its placement, resizing may be the more useful first step. Then compare a WebP export with the resized JPEG and decide which version suits the destination.
Keep the JPEG for incompatible destinations
Some forms, editors or older workflows still require JPEG. Keep the source rather than converting a WebP back every time. Repeatedly moving between lossy formats can add unnecessary changes to a photo that already has a perfectly usable original.

Frequently asked questions
Does it keep the same dimensions?
Yes. The WebP export keeps the decoded pixel width and height.
Can WebP fix a low-quality JPEG?
No. Changing formats cannot restore detail already lost in the JPEG.
Why use the quality slider?
It lets you choose the trade-off between visible detail and file size. The size shown below the preview is the result to compare.
Will JPG to WebP add transparency?
No. The JPEG source does not contain a transparent background to preserve. Use Background Remover for an actual cutout.
Can I use this to convert several JPEGs together?
This page processes one image at a time. The batch tool currently compresses to JPEG rather than making a batch of WebP files.
