WEBP Format
WEBP is a modern image format developed for the web, supporting both lossy and lossless compression as well as transparency and animation. Lossy WEBP typically produces files twenty-five to thirty-five percent smaller than JPEG at similar visual quality for photographs. Browsers including Chrome, Firefox, Safari, and Edge render WEBP natively, making it a strong default for sites you control.
WEBP transparency competes with PNG for cut-out product shots and UI elements, often at smaller sizes than PNG for comparable content. Not every legacy system accepts WEBP attachments—some email clients still treat it as a generic file—so JPG remains the compatibility fallback when you cannot predict the viewing environment.
FileShrinkr exports WEBP with the same quality slider used for JPG compression. Choose WEBP for blog images, product galleries, and app assets where modern browser support is assured. Compare JPG and WEBP outputs from the same source when migrating a site; smaller WEBP files improve LCP without visible quality loss when tuned correctly.
