Before you convert

  • Keep a backup of your original file before converting so you can roll back if needed.

Quality tips

  • Use the resize controls to match the pixel dimensions your project actually needs.
  • Preview the background fill—set it to white, black, or brand colors so transparent elements look intentional.
  • Start with a high-quality setting (85–90%) and only reduce it if file size targets demand it.
  • Download the result immediately and open it in the target application to verify everything matches expectations.
