محوّل PNG إلى JPG

The single biggest size reduction available

PNG stores every pixel exactly; JPEG throws away detail the eye is unlikely to miss. Converting a photograph from PNG to JPEG routinely cuts the file by 80–95%, which is why almost no photograph on the web is a PNG today.

The catch is the same as the benefit: the discarded detail is gone. This is a one-way conversion unless you kept the original.

The transparency problem

JPEG has no alpha channel. Where a PNG has transparent pixels, the conversion has to put something there — usually white, sometimes black. If your image has transparency, it will not survive this conversion; flatten it onto a chosen background first, or use WebP instead, which keeps transparency and is still much smaller than PNG.

When PNG to JPEG is the wrong move

• Screenshots and text — JPEG artefacts land exactly on letter edges, where they are most visible.
• Line art, logos and icons — sharp edges and flat colour are what JPEG handles worst.
• Anything with transparency.
• Anything you will edit repeatedly — each save re-compresses.
