PNG to JPG Converter

PNG stores every pixel exactly, which makes it wonderful for editing and enormous for sending. Converting a photograph to JPG typically cuts it to a fraction of the size with no difference you can see. PhotoTray does it locally, on a folder at a time, without asking you to upload anything.

Why convert

Why convert PNG to JPG

Size, nearly always. A screenshot or a photo saved as PNG can easily be ten megabytes where the JPG would be four hundred kilobytes, and email attachment limits, upload forms and page-load budgets all care about that. The exception is anything with transparency — see the FAQ before converting a logo.

  • Getting photos under an email or upload size limit.
  • Shrinking screenshots that are needlessly large to send.
  • Preparing images for a site or form that rejects large files.
  • Converting an export folder from a tool that only writes PNG.

How it works

Convert PNG to JPG in a few clicks

  1. 1

    Drop your PNG files in

    One or a whole folder — there is no count limit.

  2. 2

    Choose JPG and a quality

    The default is high enough to be visually identical on photographs. Lower it when size matters more than fidelity.

  3. 3

    Get the smaller files back

    In the folder you chose, with the PNG originals untouched.
