JPG to WebP helps you convert JPG images to modern WebP format for smaller file sizes. Processing runs in your browser — your files are processed in your browser whenever possible.

When to use JPG to WebP

Many uploads enforce strict file size limits. JPG to WebP automates optimization so you can get close to your requirements without desktop software or manual quality sliders.

Whether you are preparing a passport photo, a scanned document, or a profile image, this tool gives you a fast, private way to prepare a compliant file.

How it works

Upload your image using drag and drop or the file picker. CompressKB reads the file into memory on your device and processes it using HTML Canvas — no server upload required.

The image is rendered on a canvas and exported in the target format with high-quality default settings.

Your files are processed in your browser whenever possible. Your files stay on your device while you compress or convert them.

Tips for best results

Start with a reasonably sized source image. Cropping unnecessary areas before compression or resizing usually produces better visual quality at smaller file sizes.

Keep your uncompressed original as a master copy. You can always re-run the tool with different settings if needed.
