Convert PNG to JPG

Turn a PNG into a JPG and watch the file size collapse. The usual reason is a PNG carrying photographic content it was never suited to.

Why use this converter

  • Dramatically smaller

    Photographic PNGs commonly drop by 80-95%.

  • Universally accepted

    JPG is the safest format for publishing, email and printing.

  • Ideal for oversized screenshots

    The most common PNG complaint.

  • Batch friendly

    Convert a folder in one pass.

When JPG is the right target

Almost always about weight or compatibility rather than appearance:

  • Photographic content saved as PNG: PNG is a poor container for photos and inflates them badly.
  • Cutting page weight: For photographs a JPG is a fraction of the size.
  • A PNG too large to send: Screenshots routinely exceed attachment limits.
  • Publishing where size matters: Any page carrying many images.

Why photographic PNGs are so heavy

PNG is lossless: it reconstructs the original exactly and never discards detail. It compresses by spotting repetition, which is plentiful in flat colour and almost absent in a photograph.

So a photograph gives PNG very little to work with, and the file stays enormous. The same picture as JPG can be a tenth of the size with nothing visible lost, because JPEG discards precisely the detail the eye does not track.

When to keep the PNG

Keep it when transparency matters — logos, icons and anything designed to sit over another background rely on it, and flattening to white destroys that.

Keep it too for screenshots that are mostly text, diagrams or line art. Those are the images JPEG handles worst, producing faint smudging around sharp edges, which is exactly what PNG exists to avoid.

Frequently asked questions

What happens to transparency?

Transparent areas are filled with white, because JPG has no transparency channel. Keep the PNG if that matters.

How much smaller will it be?

For photographic content, commonly 80-95% smaller. Flat-colour graphics see less benefit.

Will quality drop?

JPG is lossy, but at the quality used here the difference is not visible at normal viewing sizes.

Should I ever keep the PNG?

Yes — for transparency, for text and line art, and for anything you intend to keep editing.
