How to convert JPG to WebP
- Drag your JPG files into the box above or click “Choose files” (folders and pasting from the clipboard work too).
- WebP is preselected as the output format; adjust quality, size and target file size if you like.
- Press “Start converting”; files are converted in your browser, in parallel.
- Download the files one by one or grab them all as a ZIP.
Why convert JPG to WebP?
At the same visual quality WebP is usually clearly smaller than JPG and PNG, which improves page speed and Core Web Vitals.
JPG files are already lossy; converting to another lossy format can add generation loss, so keep the quality setting high.
JPG vs WebP
| JPG | WebP | |
|---|---|---|
| File extension | .jpg / .jpeg | .webp |
| Compression | Lossy | Lossy + lossless |
| Transparency | No | Yes |
| Animation | No | Yes |
| Typical file size | Small | Very small |
| Support | Everywhere | All modern browsers |
| Best for | photographs, e-commerce product shots, email attachments | websites, blog images, smaller replacements for JPG and PNG |
JPG (JPEG) is the most widely used image format, built for photographs and based on lossy compression. WebP is a modern format from Google that offers lossy and lossless compression, transparency and animation. Some older software and print/office tools cannot open WebP.
Tips for the best results
- For most photos a quality of 80–85 is visually indistinguishable while making the file much smaller. If you have a size limit, use the “Target file size” option.
- For the web, limiting the width to 1600 pixels cuts file size a lot while keeping visual quality (Resize section).
- Metadata such as GPS location and camera details (EXIF) is always removed from the output.
Privacy and security
Conversion runs entirely in your browser (using WebAssembly); your images are never uploaded to our server and never leave your device. The server only receives anonymous counters that contain no file names or content (source/target format, size, duration). Metadata such as location and camera details is always stripped from the output.
