Image to WebP
Convert any image to WebP for a smaller file that still supports transparency.
One Format That Replaces Both JPG and PNG
WebP was designed to do both jobs: it compresses photographs more efficiently than JPEG and it supports transparency like PNG, which means a single format can replace both across a website. In practice you can expect roughly a third off a JPEG and around half off a PNG at a quality level nobody notices. Every browser in current use reads it, so for anything that lives on the web there is little reason not to. Keep an original in a traditional format if the image will also be printed or opened in older desktop software.
How to Convert an Image
Upload your image
Load a JPG, PNG, WebP, or GIF file from your device.
Pick the target format
Choose JPG, PNG, or WebP. For JPG, set the quality and a background colour for any transparent areas.
Download the converted file
Compare the source and result sizes shown above the preview, then save the converted image.
Where WebP Fits Best
- Cutting the total weight of an image-heavy website
- Improving page-speed and Core Web Vitals scores
- Replacing both JPG and PNG assets with one format
- Serving transparent graphics at a fraction of PNG's size
- Reducing data use for visitors on mobile networks
- Preparing images for a modern static site or CMS
Image to WebP Questions
Is WebP supported everywhere?
In browsers, yes - every current one reads it. Some older desktop applications still do not, so keep an original if the file leaves the web.
Does WebP support transparency?
Yes, it has a full alpha channel, which is what lets it replace PNG as well as JPEG.
How much will I save?
Roughly a third coming from JPEG and around half coming from PNG, though it varies with the image. The exact numbers appear above the preview.
What quality setting should I use?
85-90% keeps the result visually identical for almost every image while still delivering most of the size saving.
