Convert JPG or PNG to WebP

Add the source file, confirm that WebP is selected and adjust the quality setting if needed. The preview reports the generated size before you download the converted image. Processing happens in the browser rather than on a remote conversion server.

A format change creates a new delivery file. It does not add detail missing from the source, and repeated lossy conversion can introduce artifacts. Keep the original JPG, PNG or design export for future editing.

  • JPG to WebP: useful for photographs
  • PNG to WebP: useful when transparency must remain
  • AVIF to WebP: useful for software that cannot open AVIF
  • WebP quality around 75–85: a practical starting range for photos

Choose lossy or lossless behavior by content

Photographs generally respond well to lossy WebP because gradual color changes hide small encoding differences. Screenshots, diagrams and small text need closer inspection and may require a higher quality setting.

Transparency is preserved when the source and browser encoder support it. Check edges against both light and dark backgrounds before publishing a logo or product cutout, because pale halos can be difficult to notice on a single preview color.

Publish WebP with dependable dimensions

Use the converted file at an appropriate pixel width and include width and height attributes in the final HTML. The format alone cannot correct an oversized source or prevent layout movement while the image loads.

Modern browsers support WebP broadly, but an older desktop application or third-party upload form may still reject it. Test the actual destination before converting a large batch, and keep JPG or PNG fallbacks where compatibility is a contractual requirement.
