Practical guidance
Creating smaller web images from PNG photos or graphics while retaining transparent backgrounds.
A static WebP at the original dimensions, encoded with the selected lossy quality setting.
Compare small text and sharp edges at full size. Keep PNG when exact lossless pixels matter.
A transparent product image can benefit from WebP delivery, but lettering and sharp edges may change with lossy encoding. Compare the result on both light and dark backgrounds. A higher quality setting may help, while a larger output is a reason to retain the PNG.
Good to know
Yes. WebP supports transparent pixels, and this converter retains them from static PNG input.
No. The browser encoder uses a quality setting; this tool does not expose a lossless WebP mode. Keep the PNG if exact pixel preservation is required.
No. This tool processes your file inside your browser and does not send its contents, name or metadata to Filemivo.
Yes. It is free to use and has no artificial file-size limit. Your browser and device memory determine the practical limit.
