Common questions
Start with the final destination requirements, keep the source aspect ratio unless a crop is required, and export only the dimensions needed for smaller messages that send quickly and stay within attachment limits.
Yes. ResizeWizard performs supported resizing, compression, and conversion in your browser, so the image does not need to be uploaded to our servers.
JPG is a practical choice for photographs, PNG for transparency or sharp interface graphics, and WebP for efficient modern web delivery when the destination supports it.
