PNG is lossless and supports transparency — perfect for screenshots, logos, and graphics with sharp edges. JPG (or JPEG) is lossy but far more efficient for photographs, typically producing files 5 to 10 times smaller than the equivalent PNG.
Convert PNG to JPG when file size matters more than a perfect pixel copy: emailing photos, uploading to sites with size limits, printing at a shop, or preparing images for older software and CMS uploaders that don't accept modern formats.
Morphio decodes your PNG with the browser's native image decoder, paints it onto an HTML canvas with a white background (JPG has no transparency), then exports it as a high-quality JPG usingcanvas.toBlob. The whole pipeline runs locally, so there's no upload progress bar — there's nothing to upload.
