Drop your JPG or PNG files and download them as WebP: the same picture at the same visible quality, in less space, and shown by every current browser. The conversion runs in your browser, free and without an account.
For a website, switching the images to WebP is among the easiest ways to cut page load times.
How to turn JPG and PNG into WebP
- Drag JPG or PNG files, or the folder that holds them, onto the drop zone.
- Check that WebP is set as the output format.
- Keep the quality at 85, or adjust it for the kind of image.
- Click Convert and download the WebP files singly or as one ZIP.
How much smaller the files get
There is no fixed figure. The saving depends on the picture and changes from file to file. Photos usually end up noticeably lighter than a JPG of the same visual quality. Screenshots and graphics that started as PNG often shrink far more, since WebP offers both lossy and lossless compression. Convert a handful of your own images and compare before you switch a whole site.
Settings for photos and for graphics
Quality runs from 1 to 100 and behaves like the JPG setting: lower numbers mean smaller files with less detail. For photos, the default of 85 is safe, and dropping to 75 or 80 shrinks files further with hardly any visible difference. Logos and screenshots have hard edges that turn soft at low settings, so give them around 90 to 95. Transparency carries over, so a PNG logo on a clear background stays clear.
Where WebP opens, and where it may not
Every current web browser displays WebP, so it is a safe choice for a website. Beyond the browser, support is good but patchy: upload forms, email clients and older image editors sometimes refuse it. Keep your originals, and send a JPG when you do not know what the other person uses. A WebP can always go back to JPG or PNG with the image converter.
On a web page, the HTML picture element can offer the WebP first with a JPG fallback inside it. Each browser takes the first format it understands.
Converting a whole site
The conversion runs on your own device, so there is no batch cap and no daily allowance. Drop the image folder, convert it, and download a single ZIP. Speed depends on your computer or phone, and each image can be up to 50 MB.
The Web images preset in the pipeline builder does the full job for a folder: it resizes every image to 1600 pixels, converts it to WebP and strips the metadata. Pipelines are free to try on up to 3 files, and Pro runs them on up to 500. Credits cover one large job without a subscription, at one credit per 25 files. Larger pipeline runs are processed on our servers in Germany and deleted automatically within two hours.
FAQ
Are my images uploaded?
No. On this page the WebP encoder runs inside your browser, so the images never reach our servers.
Does the WebP keep the photo's location data?
Not reliably. To be certain it is gone, add a metadata-stripping step to the same pipeline, or clean the WebP files with Remove EXIF.
Can animated images become WebP here?
No. The WebP format itself can hold animation, but this tool only handles still images.
