About the Image Converter

A hero photo exported as PNG can weigh five times more than the same image as WebP — and your visitors pay for that in loading time. Drop up to five images here, pick a target format, dial in the quality, and watch exactly how many kilobytes each conversion saves before you download anything.

Converting to JPG flattens transparency onto a clean white background, so logos and screenshots never come out with a muddy black halo. Everything happens on your device with the browser's own canvas encoder: no upload queue, no watermark, no file ever leaving your machine.

How to use it

  1. 1Drop up to 5 images onto the upload zone (or click to browse).
  2. 2Choose the target format — PNG, JPG or WebP — and set quality for JPG/WebP.
  3. 3Click Convert, compare before/after sizes, then download each result.
