How to convert JPG to WebP for lighter images and faster pages

This JPG to WebP converter re-saves a JPEG photo as a WebP file, which is often lighter at similar visual quality. Pick a quality level, convert, and compare the size shown on the preview with your JPG before you download. It suits website images, blog photos and product pictures, and it works in a browser with no software to install.

Turn a JPEG into WebP and compare the size

The preview shows the new WebP with its size in KB, so you can judge the saving before you commit. Each change to the quality slider clears the result, which lets you try 90, then 80, and keep the lowest setting where the picture still looks right at the size it will be displayed.

  1. Upload a JPG or JPEG file.
  2. Move WebP quality, or leave it at 90.
  3. Select Convert to WebP and read the size badge.
  4. Select See result, then Download.

Choose a WebP quality for photos

For photographs, leave Lossless mode off and use the quality slider, which runs from 20 to 100. A JPG has already been compressed once, so very low WebP settings stack a second round of loss on top of the first. Moderate settings keep the picture clean and still trim the file. Judge the result at the size it will appear on the page, not zoomed in.

Why Lossless mode can make a WebP bigger than the JPG

Lossless mode stores every pixel of the decoded JPG exactly, including the compression noise already in it, so the WebP can end up larger than the JPG and it does not restore any detail. Use it only when a later editing step needs exact pixels. For web delivery, the quality slider gives the lighter file.

Convert a folder of JPGs to WebP

Switch to Batch to queue many JPG files and convert them with the same quality or Lossless setting. Batch mode is a Premium feature, and the WebP files come back together in one ZIP. Without Premium, convert the photos one by one and note which quality setting worked.

Before you replace images on a website

Open the original and the WebP together in an image comparison slider to spot softened detail. Pictures far wider than your layout should be scaled to the pixel size you need before converting, because the converter does not resize. Logos with a see-through background should start from the PNG version, and a print shop that wants lossless files needs a PNG copy of the JPG instead.

Lower quality settings can soften fine detail, so slide between the original and the WebP before you replace anything. Logos with a see-through background should go to WebP from the PNG version so the transparency carries over, photos wider than your layout can be scaled to exact pixel dimensions, and a print shop or editor asking for lossless files needs a PNG copy of the JPG instead.
