JPG to WebP converter
Change a JPG image into a WebP without uploading it anywhere. Set a KB limit if your form needs one, then download the converted file.
Runs in your browser — the file never leaves your device

Choose imageCuts file size significantly at the same visual quality, which is why it is the default choice for images on a website you control. The format almost every form and portal accepts. Lossy, so it trades a little detail for a much smaller file, and it cannot store transparency. By contrast, usually the smallest of the three at the same visual quality, and it supports transparency. Excellent for websites, but many government portals still reject it.
What this fixes
Step by step
Drop in a .jpg or .jpeg file, or tap to choose one. It is read directly in this browser and never uploaded.
The format is already set to WebP. Add a KB limit if a form caps the file size, or leave it at 0 to keep full quality.
The result keeps the original pixel dimensions and is named after your file with a .webp extension.
Common questions
The questions people actually ask about this tool — file sizes, formats and what a form will accept.
Still stuck? Contact usUpload your JPG file above and it is converted to WebP straight away. The conversion happens inside your browser, so the file is never uploaded, and you can download the WebP immediately. If a form also caps the file size, set the KB limit before downloading.
No. The extension is only a label — the actual image data inside the file is still in the original format. Many portals read the file header rather than the name, so a renamed file fails validation. A real conversion re-encodes the image data, which is what this tool does.
WebP is a lossy format, so a small amount of detail is discarded when the image is re-encoded. At the default quality the difference is not visible at normal viewing size. Setting a very low KB limit is what makes quality loss noticeable.
No. The converter is free with no daily limit, no watermark and no account. Because it runs in your browser rather than on a server, there is nothing to meter.
